Ski Chairlift, Aerial Tramway, or Gondola Stoppage in Extreme Cold¶

Aerial ropeways, including open-air mountain ski chairlifts, enclosed alpine gondolas, large-cabin reversible aerial tramways, and open-basket amusement park Ferris wheels, suspend passengers 8 to 60 meters (26 to 200 feet) above steep, rocky, or snow-covered ground on tensioned steel haul ropes. While aerial ropeways are statistically among the safest modes of passenger transport per kilometer traveled (governed by ANSI B77.1 in the United States, CSA Z98 in Canada, and EN 12929 / CEN across Europe), an unexpected mechanical failure, electrical grid blackout, crosswind safety trip, or haul-rope deropement (when the steel cable jumps off a tower's rubber-lined roller sheaves) creates an immediate multi-hour survival crisis. On an open ski chairlift stalled above timberline in minus 15 degrees Celsius (5 degrees Fahrenheit) temperatures with 60-kilometer-per-hour (37-mile-per-hour) crosswinds, immobile riders sitting on conductive metal-and-vinyl seats lose body heat four times faster than active skiers on the slope below, facing severe hypothermia and frostbite within 45 to 90 minutes.

Even more urgent is acute restraint-bar slip and misloading dangle, where a child or adult fails to get their hips all the way back onto the chair at the bottom loading bullwheel, or slips forward under the metal restraint bar on an icy seat, ending up hanging by their arms or caught by a backpack strap 12 meters (40 feet) above hard-packed snow. Knowing how to catch and stabilize a dangling child without getting pulled out of the chair yourself, why you must never bounce or jump from a stalled chairlift (which triggers a deadly harmonic cable wave or fatal decelerative trauma on hardpack snow), and how to thread a ski patrol T-seat / evacuation harness under your arms and skis during a vertical rope lowering saves lives.

Do this now¶

If your ski chairlift, gondola, or Ferris wheel stops unexpectedly right now, or if a rider slips forward under the restraint bar during loading or mid-span travel, execute these six immediate steps:

1. If a child or companion slips partly off the chair at the bottom loading station, SCREAM "STOP THE LIFT" and hook one arm over the metal backrest frame first: You have 3 to 5 seconds before the chair climbs up the first tower beyond the safety net. Shout at the lift attendant to hit the red Emergency Stop button, hook your inside arm tightly around the vertical steel center pole or backrest frame of the chair so you cannot be pulled off, and grab the slipping person's jacket armpit, belt, or backpack harness with your other hand.
2. If a rider is dangling beneath the chair mid-span and cannot be pulled up, release their heavy skis FIRST if reachable and wait for the Ski Patrol Catch Net: Heavy alpine skis and boots add 8 to 12 kilograms (18 to 26 pounds) of dead weight to a dangling child's legs and prevent them from swinging a knee back onto the seat. If you can reach their bindings or if they can kick one ski heel against the other binding lever, pop the skis off (watching that no skiers are directly underneath). If the person is slipping from your grip and is less than 6 to 8 meters (20 to 25 feet) above deep unpacked powder or a held Ski Patrol catch tarp, tell them to drop feet-first with knees slightly bent and roll backward upon landing.
3. If the chairlift stops mid-mountain, KEEP THE RESTRAINT BAR DOWN and never bounce, rock, or swing the chair: Bouncing or swinging a chair on a stalled lift sends a violent vertical and lateral wave down the steel haul rope, which can knock the cable off the adjacent tower's roller assembly (deropement) or activate the brittle-bar safety cutout switch, turning a 5-minute pause into a 4-hour rope evacuation.
4. Huddle shoulder-to-shoulder immediately, tuck hands inside your jacket (out of glove fingers), and break wind exposure before you start shivering: On an open chairlift in sub-zero wind, you do not generate metabolic heat because your legs are hanging still. Immediately zip every vent, pull your hood over your helmet, press your torso tightly against the person next to you, pull your thumbs and fingers out of individual glove slots into a fist inside the palm of your glove (or tuck hands into your armpits), and drape a trail map, backpack, or spare shell across your windward thighs.
5. NEVER jump from a stalled chairlift, even if the ground below looks like "only 5 meters (16 feet)": Because featureless white snow eliminates visual depth perception (flat-light illusion), a chair that looks 4 meters (13 feet) off the ground is routinely 9 to 12 meters (30 to 40 feet) high (equivalent to jumping off a three-to-four-story building roof). Machine-groomed ski trails are also frozen nearly as hard as concrete, and landing in stiff plastic ski boots transfers the entire impact straight into the tibial plateau, pelvis, and lumbar spine.
6. When Ski Patrol arrives beneath your chair for a rope evacuation, keep your skis ON (unless ordered otherwise) and do NOT raise the restraint bar until told: Ski patrol uses a weighted throw-line or tower cable pulley to hoist a padded evacuation T-bar or triangle harness up to your chair. Keep your hands ready to catch the haul cord, thread the harness behind your back and under both armpits as instructed by the ground patroller on the megaphone, and wait until the patroller takes tension on the belay rope before lifting the bar and sliding smoothly off the seat.

Comparison matrix: aerial ropeway failure modes, height illusions, and evacuation systems¶

Understanding how different aerial lift systems operate explains what is happening during a stoppage and how rescuers will get you down.

Deep dive 1: Preventing and surviving a chairlift restraint-bar slip or dangle¶

Falls from ski chairlifts cluster overwhelmingly at two moments: the first 15 seconds after boarding at the bottom terminal (misloading) and the last 10 seconds approaching the top terminal (lifting the restraint bar too early while icy pants slide off the seat).

1. Why children and skiers in slick Gore-Tex pants slide under the bar¶

1. The "Half-Cheek" Misload at the Bottom Bullwheel: When a small child (or a snowboarder / beginner skier distracted by poles) stands at the "Load Here" line, the moving chair scoops behind their knees. If their backpack hits the backrest or their short legs prevent them from pushing their hips all the way back to the rear of the seat cushion, they end up perched on the front 10 centimeters (4 inches) of the wet, icy vinyl seat. The moment the adult next to them pulls the overhead steel restraint bar down, the bar pushes the child's chest slightly forward while their slick nylon snow pants slide straight out from under the bar.
2. How to Load Children Safely Every Time:
3. Take Backpacks OFF and Hold Ski Poles in One Hand: Before stepping to the load line, remove all backpacks and hold both ski poles in one hand (straps off the wrists).
4. Grab the Child's Waistband / Jacket Back at Load: When riding with a child under 1.25 meters (50 inches) tall, place your hand behind their lower back as the chair arrives and lift/slide their hips all the way back against the backrest before the chair leaves the flat loading carpet.
5. If a Misload Happens in the First 3 Seconds, Do Not Try to Pull Them Up Alone: Shout "STOP" immediately: Every bottom loading station has a 3-to-5-meter (10-to-16-foot) horizontal safety net just beyond the ramp. If a child fails to get onto the seat at the load line, let them drop onto the snow ramp immediately (within the first 2 meters) or scream for the operator to hit the red E-stop before the chair rises past the safety net.

2. How to hold a dangling skier until Ski Patrol deploys the Catch Net¶

If a rider slips under the restraint bar mid-span and is hanging 8 to 15 meters (25 to 50 feet) above the trail:

                                3. Wait for Ski Patrol Catch Net below

1. Anchor Yourself to the Steel Chair Frame First: If you simply lean forward over the edge of an icy chair seat with both arms to grab a 50-kilogram (110-pound) falling person, their downward drop will pull you straight under the restraint bar after them. Lock one elbow or forearm firmly behind the vertical steel center support tube or over the backrest frame, braced with your ski boots against the footrest if present.
2. Grab Fabric or Straps, Not Slippery Nylon Gloves: Smooth waterproof ski mittens pull off a dangling person's hands in two seconds. Grab a double handful of the back of their jacket collar, under their armpits, their belt loop, or the shoulder strap of their bibs.
3. Shed the Skis if You Cannot Hoist Them Up: If two adults on the chair cannot haul the dangling person back onto the seat because their ski boots and skis are catching underneath the front lip of the seat cushion, tell the dangling rider to use the tail of one ski to press down on the heel-release lever of the other ski binding to drop the heavy skis (after shouting "HEADS UP, FALLING SKI" to clear the slope below).
4. How to Land Safely into a Ski Patrol Catch Net / Decelerator Pad:
5. Within 2 to 4 minutes of a lift stop for a dangling rider, Ski Patrol and lift operations race down the slope with a heavy-duty circular nylon catch net or deep foam decelerator tarp held taut by 6 to 10 patrollers directly underneath the chair.
6. Once the Patrol Leader on the ground shouts "NET IS SET, DROP ON THREE," the dangling rider should keep their chin tucked to their chest, cross their arms over their chest, bend their knees slightly, and let go cleanly without pushing off horizontally, allowing their feet and buttocks to contact the center of the net simultaneously and rolling onto their back.

Deep dive 2: Surviving a multi-hour lift stall in sub-zero cold and high winds¶

When a chairlift stops due to a gearbox failure, tower sensor fault, or power outage, do not assume you will be moving again in two minutes. In alpine storms where temperatures drop below minus 10 degrees Celsius (14 degrees Fahrenheit) with 50 km/h (31 mph) winds, wind chill reaches minus 25 to minus 35 degrees Celsius (minus 13 to minus 31 degrees Fahrenheit), where exposed facial skin freezes in under 10 minutes and core body temperature begins dropping rapidly.

1. Five immediate heat-retention tactics on an open chairlift¶

Because you are sitting still in a metal chair suspended in the wind stream with your tight ski boots compressing circulation in your feet: 1. Turn Your Ski Gloves into "Mittens" Immediately: Inside a five-finger ski glove, your isolated fingers freeze quickly. Pull your four fingers and thumb out of their individual finger stalls and ball your bare hand into a tight fist inside the main insulated palm cavity of the glove (wrapping your fingers around a chemical air-activated hand warmer packet if you carry one in your pocket). 2. Unbuckle the Top Two Buckles of Your Tight Ski Boots: Tightly clamped plastic alpine ski boots restrict arterial blood flow to your toes, accelerating frostbite while your legs dangle downward. Reach down carefully (keeping the restraint bar down and one hand on the chair) and flip open the lower foot buckles by one or two notches so warm blood can reach your toes, then wiggle your toes vigorously inside your boots for 60 seconds out of every 5 minutes. 3. Eliminate the Wind Tunnel Behind Your Back and Under Your Thighs: - Many chairlifts have perforated steel mesh seats or open gaps between the seat cushion and backrest where freezing wind blasts straight into your kidneys and lower back. - Stuff a backpack, folded trail map, spare fleece layer, or sit-pad across the gap behind your lower back, and press shoulder-to-shoulder and hip-to-hip with your chairmates (huddling reduces exposed surface area heat loss by up to 35 percent). 4. Protect the Face Without Breathing Moisture Inside Your Goggles: Pull your neck gaiter (buff) or balaclava up over your nose and cheeks, pull your jacket hood over the outside of your ski helmet to seal out wind through the helmet vents, and leave a tiny breathing gap for exhaled steam so your goggles do not ice over completely. 5. Perform Isometric Muscle Contractions Without Rocking the Chair: You cannot bounce or swing your legs (which shakes the cable), but you can perform isometric heat-generating exercises by squeezing your thigh muscles (quadriceps), glutes, abdominal core, and shoulder muscles tightly for 10 seconds, releasing for 5 seconds, and repeating continuously to generate internal metabolic warmth (hypothermia and frostbite).

2. Why you must NEVER jump from a chairlift (The "White-Room" Height Illusion)¶

During almost every prolonged chairlift stoppage, one or two impatient or freezing skiers look down at the snow trail underneath their skis, conclude that the ground is "only 4 meters (13 feet) down," lift the bar, and jump, resulting in shattered calcanei (heel bones), burst lumbar vertebrae (L1-L2), open tibial fractures, or fatal aortic/head injuries: - Why Your Eyes Lie to You Over Snow: The human brain judges vertical height by comparing the size of familiar ground textures (grass blades, pavement cracks, shrubs). Looking down at a featureless white snowfield ("flat light") completely erases stereopsis depth cues, causing riders to underestimate height by 40 to 60 percent. A standard chairlift tower cross-arm sits 9 to 18 meters (30 to 60 feet) above the trail. - Rigid Ski Boots Act as Force Multipliers: Landing from even 5 meters (16 feet) in locked, rigid plastic alpine ski boots prevents the ankle joint from flexing to absorb energy, driving thousands of Newtons of impact straight up the tibia into the knees, hip sockets, and spine.

Deep dive 3: Step-by-step guide to a Ski Patrol vertical rope evacuation¶

If the chairlift cannot be restarted using the auxiliary diesel engine or evacuation APU within 30 to 60 minutes, Ski Patrol initiates a manual rope evacuation (lift evac). Knowing the exact procedure removes panic when patrollers arrive beneath your chair.

   [Snow Ground] ===[Patroller on Friction Brake]===> Lowers rider smoothly

1. Wait for Your Chair's Turn (Patrol Works Systematically): Multiple two-person or three-person Ski Patrol teams start at different sections of the lift and work from chair to chair. Do not raise your restraint bar until a patroller is standing directly below your chair and addresses you by name/chair number over a megaphone.
2. Drop Loose Ski Poles ONLY When Instructed: The ground patroller will first ask you to drop your ski poles onto the snow (clear of the ground crew) so your hands are completely free. Keep your skis or snowboard ON your feet unless the patroller specifically tells you otherwise (sliding off the chair and touching down on the snow slope at the bottom of the rope is much safer and smoother on skis than in slick plastic boot soles).
3. Catch the Haul Line and Thread the Evacuation T-Seat / Harness:
4. The patroller pulls a lightweight rope over the main steel haul cable (or uses a wheeled pulley block rolled down from the tower) to hoist a padded metal/webbing T-Seat, Evacuation Triangle (Evac Sack), or Sit-Harness right up to your chest level.
5. Pull the T-seat or harness into your lap.
6. Follow the Patroller's Exact Threading Call:
   • For a T-Seat / Evacuation Saddle: Straddle the central vertical webbing strap between your legs so the padded horizontal bar sits directly underneath your buttocks/thighs, and pass the upper chest safety loop over your head and underneath both armpits across your chest, clipping the safety carabiner or tightening the chest cinch strap so you cannot tip backward even if you let go with your hands.
   • For a Diaper / Triangle Rescue Harness: Slip the wide padded triangle behind your lower back, pull the two side rings around your waist and the center strap up between your legs, and clip the main lowering carabiner through all three rings at your waist/chest.
7. Raise the Bar, Hold the Upright Webbing (Never the Moving Rope), and Slide Off Smoothly:
8. Once you shout "CLIPPED IN AND READY," the ground patroller takes up all slack on the friction belay device ("Tension On") and commands you to raise the chairlift restraint bar.
9. Place both hands on the vertical webbing straps of your harness right in front of your chest (do NOT grab the moving rope above the pulley).
10. Scoot your hips gently forward off the edge of the chair seat so your weight settles smoothly into the harness without jumping or dropping, keep your ski tips pointed forward and slightly up as you descend, and ski away from the drop zone the moment the patroller unclips you on the snow.

Pre-ride alpine chairlift and gondola survival checklist¶

Before heading onto the mountain with your family or boarding an aerial ropeway, verify these six important preparations:

• Carry a disposable Mylar emergency space blanket and 2 chemical hand warmers in your jacket pocket: A folded Mylar thermal blanket weighs 50 grams (2 ounces), fits in a breast pocket alongside a pair of air-activated iron-oxide hand warmers, and blocks 100 percent of wind chill while reflecting radiant body heat if you are stranded on a chairlift for 2 hours.
• Remove all backpacks before loading a chairlift and secure every dangling strap: Hold your backpack on your lap during the ride so waist belts, hydration tubes, and sternum buckles cannot catch in the steel chair slats and drag you around the top bullwheel.
• Position small children on the INSIDE seat (away from the end post) or right next to an adult who guides their hips onto the chair: Help children under 1.25 meters (50 inches) get their hips all the way against the backrest at the load line, pull the restraint bar down calmly after calling "Bar Coming Down," and instruct children to sit still without leaning forward to look at their ski tips.
• Keep your mobile phone in an warm INSIDE chest pocket (against body heat) with the ski resort's Ski Patrol emergency number saved: Lithium-ion smartphone batteries plunged to minus 15 degrees Celsius (5 degrees Fahrenheit) in an outer shell pocket lose voltage and shut off in 20 minutes. Keep your phone inside your insulated mid-layer and save the resort's direct Ski Patrol Dispatch phone number (printed on the paper trail map and lift tower signs) before your first run.
• Note the Lift Name and the Number painted on the nearest steel Lift Tower: Every ski lift tower has a large black-on-yellow number (for example, Tower 14) painted on the column. If a rider is dangling or having a medical emergency on your chair, calling Ski Patrol with "Red Mountain Express, just below Tower 14" sends rescuers to your exact spot in seconds.
• On Ferris wheels and open gondolas, sit children between adults and never rock the cabin: Keep all passengers seated throughout the ride cycle and never allow anyone to kneel on the bench or lean over the side rail for photos.

Frequently asked questions¶

What should you do if a child fails to get all the way onto a ski chairlift seat and starts slipping under the bar?¶

If the misload happens right at the bottom boarding ramp, scream "STOP THE LIFT" immediately so the attendant hits the emergency stop button while the chair is still over the 3-to-5-meter (10-to-16-foot) bottom safety net, or let the child drop onto the flat snow ramp within the first second before the chair climbs into the air. If the chair is already high off the ground, the adult next to them must immediately hook one arm tightly around the steel backrest or center pole of the chair to anchor themselves first, then grab the back of the child's jacket collar, armpit fabric, or belt with the other hand (never grab slippery mittens, which slide right off). If you cannot pull the child up onto the seat, have them kick off their heavy skis if possible and hold on for 2 to 3 minutes while Ski Patrol stretches a catch net directly underneath the chair.

Why is it so dangerous to jump off a stalled ski chairlift onto the snow below?¶

Looking down at featureless white snow creates a powerful optical illusion ("flat light") that makes a chairlift look half as high as it actually is; a chair that looks 4 meters (13 feet) off the ground is usually 9 to 14 meters (30 to 45 feet) up, the height of a three-to-four-story building. Groomed ski trails are also packed and frozen nearly as hard as concrete, and landing in rigid plastic ski boots prevents your ankles from flexing, driving the full impact straight into your shinbones, knees, pelvis, and spine. Even worse, pushing off a stalled chair sends a violent upward whip through the steel haul cable that can knock the cable off the tower rollers ("deropement") and drop neighboring chairs.

How do you keep from freezing to death if a ski chairlift gets stuck in sub-zero wind for two hours?¶

Because you are sitting motionless suspended in high winds, you must stop heat loss within the first 5 minutes before deep shivering exhausts your energy reserves. Keep the restraint bar down, press your shoulders and hips tightly against your chairmates to share warmth, and pull your fingers out of the individual finger slots of your ski gloves to ball your hands into a fist inside the insulated palm cavity (or tuck your hands into your armpits). Loosen the bottom two buckles on your tight ski boots by one notch so warm blood can circulate to your toes, block the wind gap behind your lower back with a backpack or trail map, pull your hood over your helmet, and perform 10-second isometric muscle squeezes in your thighs and core without rocking the chair.

How does Ski Patrol evacuate riders from a broken chairlift using ropes?¶

When a chairlift cannot be restarted with its backup diesel engine, Ski Patrol teams walk along the lift line with a rescue rope that runs over the main steel haul cable above your chair. Keep your skis or snowboard on your feet and keep the restraint bar down until the patroller standing directly beneath your chair speaks to you on a megaphone. After asking you to drop your loose ski poles, the patroller hoists a padded T-seat or triangle rescue harness up to your lap. You slip the strap between your legs and the safety loop over your head and under both armpits, verify the safety clip is fastened, wait for the patroller to take tension on the belay rope, then lift the restraint bar and slide smoothly forward off the seat so the patroller can lower you gently to the snow.
