    The NEW Magic Mountain

    am wondering what the download capacity of the black lift is? this would be supplied in the design package. iirc, most lifts can easily be qualified for 10% { every 10th chair fully loaded downhill } because it takes about 17% to drive an empty lift. with only a 10% load, there would be no...

    The NEW Magic Mountain

    some may not know that once a lift is relocated, it must adhere to the latest B77 standard. very, very expensive as you might guess. there have been, of course, improvements in grip design, tower fall protection, motor control and various safety circuit logic paths during the iterations of the...

    re: magic development. prudent area owners frequently try to balance growth overall, looking out 10 years. lift capacity/efficiency first, with matching snowmaking coverage, trail capacity, bar stools and lodge beds, parking lots { and more }, following. throw in the variances of weather...

    The NEW Magic Mountain

    "lower restraint bar" sign is there, tower is numbered, tip guard is there, and grip match-marks too? those final details are real time killers. looks like a very nice install.

    The NEW Magic Mountain

    must be a gage/guage difference between the bullwheel and line. that said, not sure i've seem hor sheaves to help maintain cable alignment to the entry/exit sheaves before. no matter. the lift is up and running. :thumbup:

    The NEW Magic Mountain

    during acceptance testing, each manually operated switch will be tested. stops, slows, comm, machine room lanyard stops, apu e-stops, etc,etc. tower annunciation must be somehow proven, does a trip on T4 show as T10? not good. load lines, signage, portal ropes, apu instructions, all posted...

    The NEW Magic Mountain

    a successful "load test" means the lift's electronic drive can control the load. to pass, the electronic drive would have to accelerate the line to design speed, hold it there, and then decelerate per the standard. not too fast nor too slow. each individual brake { service, emergency and...

    The NEW Magic Mountain

    when the original skye peak quad (iirc) was built at K, it was intended to have an aux hydraulic drive powered by a grooming machine. never worked, as there was enough pressure but too little flow. more field-testing at K of yanek kunczynski's ideas. good times.

    in the event of a power failure, would a large backup genset be considered an APU by the state?

    The NEW Magic Mountain

    all aerial lifts must have an APU spec'd to start, run and control 110% of the rated lift capacity and must be wired into the e-stop circuit. minimum line speed is 100fpm, concurrently all carriers must be unloaded of passengers within an hour. the designer may specify that a secondary "prime...

    Older Senior wants to get back into skiing

    how about cross-country skiing? or snowshoeing? reduced chances of breaking something when he falls, less chance of a skier collision, he'll likely enjoy being outdoors more on a path close to nature rather than being surrounded by skiing yahoos making him feel old, the weight of...

    VAIL SUCKS

    the jaws of a detachable chairlift grip encircle the haul rope to such a degree that it cannot be plucked off without great force, a faulty spring, or jaw wear from a the haul rope running through it { as in the case of a deropement leading to a carrier being stuck in a sheave train }. impact...

    Bubble lift opinions

    re: wind tolerance. it all depends on prevailing wind direction. imo, "bubbled" carriers have less wind tolerance but only slightly less and only when wind is from the front or sides. the effective area on a bubble chair is a bit larger overall, but wind affect is less due to the curved...

    Bubble lift opinions

    no love for bubbles for the guys/girls that have to maintain and operate them. lots of articulating parts and cables that need adjustment to keep them open / closed at the right position, maintenance checks / repairs on these components, maintenance / repairs / timing on the auto-closers and...

    'Yan lifts of that time period were built to the next biggest line gauge (doubles supported triple chairs, triples supported quad chairs" i know of no L/E lift that was built with a line gauge as you describe. "this is how Bear Mountain at Killington was converted so all one had to do to...

    fyi you gotta add $5 when purchasing a walk-up day ticket, then add 6% tax. that's $90 for a walk-up day ticket and $900 for a pass. https://magicmtn.com/daily-tickets/

    The NEW Magic Mountain

    a ski-lift design must satisfy a variety of load conditions on the lift line, i.e bare rope { no carriers }, empty carriers uphill/downhill, loaded carriers uphill/empty carriers downhill, downhill loading if requested, etc. of course these conditions must be satisfied under both static and...

    the red's got a good amount of carriage travel, so if the splice was done with the drive forward as much as practical, they may be able to get away with just raising the counterweight a time or two to counter the effects of a new rope's initial "stretch". on the other and, modern solid core...
