Hoist Trolley for PA200-1000 Electric Hoist 6 Wheel Trolley Assembly for use with Unistrut 1-5/8" Wide and All 1-5/8" or Taller Strut Channel,Suitable for Garage Hoist Systems

They should work great, the ball bearings roll smoothly. However I mounted the strut channel differently and made a mistake using thin fender washers, which distorted and blocked the ability to travel inside the channel. We were able to raise the new AC Air Handler up into the attic with my HF 120vac powered wench and lowered the (old heavy Air Handler) out of the attic. These handled the load well. For that load, they are overkill, but I have another use for the future and will use the proper supports (which was ordered but wasn't delivered in time).

These fit in the rail and hold an electric wench perfectly.

Worked as expected

The trolleys certainly work. I am using them to suspend a winch from unistrut in my attic so I can haul heavy items up via the winch and not risk my life on the ladder. The bearings are ok quality, the body of the trolley itself is thick steel that looks like it was cut out with a torch or plasma, welded together, then sanded/wire wheel'd and plated. As long as the welds hold it will be fine. I am not lifting anything especially heavy with it so I'm very happy with it, however if I was I would routinely check the welds for cracking and I wouldn't stand under the load....

These have worked out great for the hoist I installed in my shop. Fit as described, rolls smoothly and makes mounting hoist a snap.

Working great with a harbor freight hoist.

Worked great for lift with trolly I built to lift items to storage level of garage.

These work well in conjunction with unistrut and the harbor freight electric hoist!
