Since rigging is gone, and this is sort of F/X, thought I might throw my current project out and see if it catches any more ideas: Ok, so my current project amongst many is pricing out some economical barr keep controlled means of lowering a 48" 120# mirror ball and motor from a club’s ceiling without the thing swinging or twisting all over the place. Bridling is not an option either. At first I thought a simple 3/16" wire rope winch would suffice to lower the mirror ball, but due to the size of the mirror ball thus start up twisting from the motor, my thoughts were that this system would need rotation resistant wire rope. Problem is besides a need to braze or weld the ends of it is that 19x7 wire rope requires a 6.3/8" D/d ratio or size of wire rope drum per type of wire rope used is 34 D/d. Given at best a 3" drum on a standard 3/16" wire rope winch, this might be a wee bit of a problem. More flexible rotation resistant wire ropes such as 35x7 with a 20 d/D ratio at 3.3/4" dia for the drum (Wire Rope User’s Manual) are not available in such a small size off the shelf it would seem. With wire rope, the more strands, the more flexible and rotation resistant wire rope it would seem is of need in this situation. So here is my question, what do rescue helicopters use for dropping a person down as far as hoist type and wire rope type given it’s compact size no doubt in being a maximum of stranding? How beyond belt lift or scissors lift which would be out of budget for the project would you approach such a problem of dropping than spinning a 120# mirror ball? Anyone know about helicopter rescue equipment? Furthermore, anyone have a web address much less accurate phone number to Mutual Hardware Corporation? I’m looking for pricing or advice for a resale install of a hoist system to drop a 120# 48" mirror ball in a club. Note that the drop length is expected to be about 10' but service length can be a minimum of 20'. Also that in starting the spin of the mirror ball, we are intending to stop spin by as much as possible which on our part could include weighting the motor further for ballast. This will be in a club install so power is expected to be 120v, power will be by way of plug for maintenance, and control will be conduit based either key pad or push button controlled at a remote location. (This is also preliminary as to the pricing out of a system thus details and other economical or better working ideas will be of use in figuring out what to do and the bid for it.) I’m taking it for a given we want 115v, Single Speed CM hoist given a chain hoist: #3801a 1/8 Ton CM-Techstar Chain Hoist, 32FPM, Limit Switches, 10' of chain, #2685P Rigid Lug for Plain low head trolley, & #2450 Metal Chain Container. #2702a 1/8 Ton CM-LodStar 1/4 HP Chain Hoist, 32FPM, Limit Switches, 10' of chain, #2788 Rigid Lug for use with single chain or low headroom kit, & #2450 Metal Chain Container, #2788 Non-Swivel Load Hook, 60LBS #3102a 1/8 Ton CM-LoadStar 1/4HP Chain Hoist, 16FPM, Limit Switches, 20' of chain, #2788 Rigid Lug for use with single chain or low headroom kit, & #2450 Stock Metal Chain Container, 68LBS #2401a/wb 1/4 Ton CM-ValuStar 1/4HP Chain Hoist, 16FPM, No-Limit Switches, 10' of chain is stock, Stock Snap Hook head, #2450 Stock Metal Chain container, 52LBS #2007 300# CM-ProStar 1/6HP Chain Hoist, 16FPM, No-Limit Switches stock, 10' of chain is stock, Stock Snap Hook head, #2010 Stock Chain Bag. #2000 300# CM-ShopStar1/6HP Chain Hoist, 16FPM, No-Limit Switches, 10' of chain is stock, Standard Snap Hook Head, 25LBS #2007SC Coffing ProStar 1/6HP Chain Hoist, 16FPM, No-Limit Switches, 10' of chain is stock, Non-Swivel, 26LBS #2040 Coffing Pro Star 1/6 HP Chain Hoist, 16FPM, No-Limit Switches, 20' of chain is stock, Non-Swivel, 28LBS Above Hoists, 115v/60Hz, NEMA 1 body. All will need permanent power supply and control set up. Another option is to go motor down to add ballast to the pendulum, but it would require a larger and second set of feeder cable to reel down. Not really recommended. Wire Rope Hoists - Advantages - four wire 5:1 rigging which helps to prevent torsion and as opposed to single line hoists, won’t require rotation resistant wire rope. CM has no Wire rope hoists under 1-Ton. PCM-Performer Tau Wire Rope Winch.

Single Line wire rope Variable Capacity, Speed, & Lifting Height. #1140004, 125KG(187#), 16.73FPM, .25Kw Power, 3/16" Wire rope, 44# On wire rope for a standard single line wire rope aka-McMaster Carr winch: 35x7 rotation resistant wire rope minimum stock size is ½" but will have a tighter bending radii. 19x7 optimum size is 3/16" but minimum bending radius is 6.3/8" which would not fit on a standard 3/16" wire rope drum. Given this, what do rescue hoists use?
