Pictures of a detensioned lift

Allan's Photo Allan 04 Dec 2004

As promised, here's the pics!
#1 a general shot of the lift
#2 counterweight cable shown slack
#3 a side view of the plate clamps (used to secure the haul rope to the rigging)
#4 chair sitting a little low...
#5 view from in front
#6 view from behind
#7 view from the side!

Sorry about the huge message... but I wanted the quality :)

So what kind of work are you doing on the Red Chair, Allan?

Bullwheel bolt replacement - as per the inspector's directive from a couple weeks ago.

Allen how long does that take? what steps are taken to detension the lift?

It takes a day to detension the lift like seen here. In short: First you attach the plate clamps (one for each side) to the rope. Attach one end of the rigging to the clamp, and in this case the other end to the Mueller provided eyes in the concrete. Lower the counterweight to the ground, keep lowering until the ropes are slack (both the counterweight and the haul rope). I'm sure I've missed some steps - but that's the short of it!

Red is back in service now - my partners spent all day on it & got it backtogether. I was about the mountain for most the day... getting my ski-doo stuck more than once...

Would that the Flyer's bolts came out in a day...

If one is detensioning a fixed bullwheel as opposed to the tension sheave Allan is working on, then you need a way to pull slack. There are two ways that I've been privy to; one is a six- or eight- part block system, and the other is a large-bore long-stroke hydraulic ram. You attach the plate clamps the same way as Allan describes, but place the blocks or ram on one side in between the fixed eye and the plate clamp. You then shorten the ram, or reel in the rope on the blocks, until the haul rope become slack on the bullwheel.

Dragging out an old topic with new rigging! Lift is rigged down for a gearbox removal and overhaul.
#1 - Drive station with bullwheel ready to fly
#2 - I forget the name of these things, but they're supposed to stop the rigging/rope from spinning
#3 - closeup of the plate clamp, which holds the rope to the rigging.
#4 - general shot of the rigging
#5 - counterweight tube
#6 - the tension frame which usually sits atop the bullwheel.

#7 - And since the tucks were all sitting on the ground, an inspection was in order and I found a broken wire...

Picture 2 shows what as the name implies an anti twister and as you mentioned it does stop the rope from spinning as the rope is detensioned and retentioned. In picture 3 you also see where the anti twister is attached to the plate clamp.

maybe a little off topic, but Allan, I am unfamilar with Mueller lifts. The only one Ive ever seen was a relocated one in MN. My question is if these pictures are of a tension terminal, 1. where is the carriage travel. 2.the counterweight must be contained in the rear tower mast?? Also if the drive(gearbox/motor) are in the bullwheel mast, it must be close corridors for you to work in.

Allan, in Canada #2 is a Lazy bar, and that looks to be an original Meuller plate clamp.

Ahh the lazy bar - that's the name I've heard before :)

Skier691: The entire structure you see in pic #1 is on rollers and moves on rails underneath. The counterweight is hiding in that mast and if I remember right is a bunch of plates bolted together. Close cooridors is one way to put it :) Everything is in there, gearbox, auxiliary, electric motor, brakes etc... Very confined!

What kind of an overhaul are you doing Allan?
Reply

Allan's Photo Allan 01 Aug 2006

New crown/pinion as well as new bearings & seals. As well as anything else we find! :)

Allan's Photo Allan 12 Aug 2006

Wish I was around to get the pics of the actual removal!!
#1 - Drive station minus gearbox and bullwheel
#2 - Bullwheel on ground
#3 - She's just an empty shell! The electric motor, brake shoes and drum all removed for repair.
#4 - Bullwheel brake shoe, which has since been removed for re-lining..
#5 - The gearbox patiently waiting the Kissling rep to come for the rebuild
#6 - the rollback sheave got new bearings and liner last year... so it stays.

Hi Allan, We saved a bundle by relining the ebrake shoe with 2 strips instead of 1 large piece of material.
(added a number of rivets as well)

Mike - good idea on the two strips thing - do the strips meet in the middle, or is there a gap between them? Where do you get your shoes relined - or if you do it yourself, where do you get the material from? Our place in Castlegar that did all our brake linings closed!

My topic! Here's the other end of the lift.

#1 - general project shot - that's me under the BW on the left.
#2 - Oops derailed tower 4 while running the carriage ahead.
#3 - BW coming off pedestal, this Hiab is the best tool we own.
