Timberline Lodge & Ski Area on Mt. Hood posted the following statement on Facebook Thursday afternoon after an empty chair fell from one of its high speed quads.

At approximately 1:45pm today there was a mechanical malfunction on the Magic Mile chair lift. A chair detached from the cable on the downhill side of the lift. The chair lift was not occupied. No customers or staff were involved in the incident. All guests were offloaded in a timely manner. The Magic Mile will be closed until further notice, pending a thorough investigation involving the lift manufacturer and a 3rd party lift engineer. Timberline Lodge thanks all guests on the lift for their patience and apologizes the inconvenience. We are compiling all details of the incident, which will be posted as soon as possible.

Poma built the Magic Mile in 1992 to replace a Riblet double.  The lift is 5,472′ long, rises 1,089′ and has Poma’s TB-41 grips. Much of this lift operates above tree line, so both its terminals are housed inside buildings that can be buttoned up during storms.  Magic Mile also has indoor parking for all its chairs and grip maintenance bays at the bottom terminal.

Almost exactly a year ago, an empty chair fell from a Doppelmayr detachable quad at Mt. Bachelor in a similar incident which was later blamed on component failure.

Update 4/2/16: Magic Mile has re-opened and Timberline posted the following update this afternoon.

This is a communications update regarding the Magic Mile chairlift malfunction, which we reported on March 31. The lift has been inspected by an independent chairlift engineer along with representatives from the US Forest Service. It was determined that failure of a key component of a carrier grip occurred, resulting in the detachment of an empty chair on the downhill side of the lift.

RLK and Company chairlift technicians followed the recommendations of the chairlift engineer and performed comprehensive inspections and testing on the entire chairlift. It has been determined that the chairlift conforms to industry standards, and is now operating.

Update 5/1/16: We’ve learned Magic Mile’s safety systems worked as designed and this incident was a combination of component failure and operator error.

Will Detachable Lifts Get Faster?

Peter Landsman8 Comments

There’s a lively discussion going on over at Alpinforum about the future of detachable lifts, which haven’t gotten much faster despite huge advances in technology over the last thirty years.  The first modern detachable chairlift, Quicksilver at Breckenridge, went 787 feet a minute when it debuted in 1981.  Since then, manufacturers have installed hundreds of gondolas and chairlifts capable of going more than 1,000 fpm.

30-year old lift: 1000 ft/min
Brand new lift: 1000 ft/min

The first lift to go 1,100 fpm was the Whistler Village Gondola in 1988 and the first capable of 1,200 fpm was Stowe’s gondola in 1991.  Both were built by Poma, the early adopter of faster line speeds.  The only detachable installed in North America since 1991 capable of traveling any more than 1,200 fpm is the Peak 2 Peak Gondola, debuting in 2012. As a tri-cable gondola, P2P has an impressive capability of 1,476 fpm (7.5 m/s.) Doppelmayr claims similar systems can go up to 1,670 fpm (8.5 m/s.)  So far, the fastest 3S ever built goes 8 m/s and one that can go 8.5 will debut in Vietnam next year.  Meanwhile, 1,200 fpm (6 m/s) remains the highest speed for a single cable detachable, a stat that hasn’t changed since 1991.

avg speed over time
From 1984 to 2015, the average speed of a detachable lift in the U.S. increased by only 900 feet a minute.

The truth is the vast majority of detachable lifts built these days have the standard design speed of 1,000 fpm (5.08 m/s) and operate even slower much of the time.  In my experience, many ski areas run so-called high speed lifts at 800 or 900 feet a minute on all but the busiest of days.  As users on Alpinforum note, ski resort operators care more about reducing stops, wear and tear than shaving thirty seconds off a ride time that the average guest won’t even notice.

Kicking Horse Gondola Evacuated by Helicopter

Peter Landsman4 Comments

A transformer failed yesterday afternoon at Kicking Horse Mountain Resort, knocking two lifts out of service.  Crews restarted the Catamount quad on auxiliary but the Golden Eagle Express Gondola sustained damage to its safety systems such that it could not operate.  With nightfall approaching, some of the gondola’s 75 passengers were plucked out of cabins by helicopter at sunset, making for some pretty spectacular GoPro footage.  The rest were roped down by ground teams over about five hours. The 8-passenger, 11,188′ Golden Eagle Express was built by Poma in 2000 and rises more than 3,500 vertical feet.  The gondola remained closed today but the mountain hopes to have it back in business tomorrow.

Kicking Horse posted the following statement on Facebook this morning:

“Further to an electrical issue, the Golden Eagle Express Gondola was manually evacuated yesterday evening. With everyone safe, warm and fed, we apologize to each of you involved for the inconvenience. We are thankful that everyone is safe and credit to the talented team of professionals; Kicking Horse Mountain Resort teams, Golden and District Search and Rescue & Canadian Ski Patrol.  We are hopeful that the Gondola will be spinning later today, though currently is still on standby. We are offering skiing and snowboarding via the Catamount Chair & Pioneer Chair.  Stay tuned for further updates.”

 

Oldest Operating Lifts in the US & Canada

1. Single Chair, Mad River Glen, VT – 1948 American Steel & Wire Single Chair

The single chair at MRG still has its original towers and terminal structures but everything else was replaced by Doppelmayr CTEC in 2007.  As part of that project, towers were removed, sandblasted and repainted before being flown back to new foundations with new line gear.  Doppelmayr also replaced the bullwheels, chairs, grips, drive and haul rope.  This begs the question of ‘when is an old lift a new lift?’

2. Gatlinburg Sky Lift, Gatlinburg, TN – 1954 Riblet double

Everett Kircher of Boyne fame bought this chairlift from Sugar Bowl, CA for $3,000 in 1954.  Originally it was a single chair built in 1939.  Modified sheave assemblies were machined at the Kircher’s car dealership in Michigan when the lift went to Tennessee.  At some point it appears to have gotten newer-style Riblet towers.  Boyne Resorts still operates this lift 800 miles from their nearest ski resort. (edit: JP notes in the comments below that this version was replaced by a Riblet double in 1991.  Thanks JP!)

3. Chair 1, White Pass, WA – 1955 1962 Riblet double

This lift only operates on busy weekends and holidays but it’s an old one and a good one .  A classic Pacific Northwest center-pole double with very few modifications from its original design and no safety bars! (edit: Brian notes in the comments that this lift was actually installed as Chair 2 in 1962.  The original chair 1 operated 1955-1994.)

News Roundup: Tragedy in Oklahoma

A work chair on the Skyride at the Tulsa State Fair failed earlier this week causing two mechanics doing line work to fall.
A work chair on the VonRoll Skyride at the Tulsa State Fair failed earlier this week causing two mechanics doing line work to fall.
  • OSHA is investigating the death of one of two mechanics who fell while doing line work on the Skyride at the Tulsa State Fair.  A work chair on the 1965 VonRoll gondola appears to have failed below the hanger, dangling both men from their harnesses.  Steve Shelton, 43, died of trauma as a result.  His family set up a GoFundMe page to raise money for funeral expenses.
  • Poma is setting steel for Europe’s new highest lift in Russia.  The three-stage, two-passenger gondola on Mt. Elbrus will reach 3,847 m/12,621 feet (Breckenridge’s Imperial Express SuperChair goes 350 feet higher.)
  • Sugarloaf begins removing its oldest lift as part of a ‘lift safety’ initiative.  I guess a lift that doesn’t exist is safer than one that does.
  • Hidden Valley, New Jersey’s three Borvig lifts are out and two new Partek lifts are going in.  The ski area which closed in 2013 also has a new name – the National Winter Activity Center.  Follow the progress live here.
  • The city of Cali in Colombia will open MIO Cable, a 10-passenger Poma gondola, on Friday.  The 6,800′ system has four stations and 60 Sigma cabins that move 2,000 passengers per hour each way.
  • Deer Valley Resort, SkyTrac and the NSAA will host an evening program honoring Jan Leonard on October 14th at Snow Park Lodge.
  • Doppelmayr crews fly 11 towers for a new gondola at Lutsen Mountains, Minnesota.  The $7 million system is going up alongside the resort’s Hall gondola, which will run through October 18th.
  • It’s looking like Saddleback, Maine will have a ski season without a new lift.
