UNISTRUTGenuine P2950-EG 4 Wheel Trolley Assembly for use with P1000, P1001, P5000, P5001, P5500, P5501 and All 1-5/8" or Taller Strut Channel

I bought the trolly wheels from Amazon and then bought the p1000 track from Menards. I installed them onto a 440 lb hoist to make a trolly lift to lift steel plates. I drilled 2 pieces of angle iron and sandwiched the trolly wheels between them then bolted them together. Then I installed the hoist to to the angle iron. It was a simple and self explanatory project. The system works great. The wheels fit perfect and roll so smooth and easy. The track is strong and doesnt flex at all. There is no chance of this failing . I needed 16 feet so I welded 2 tracks together. The wheels roll so easy that I had to put stops on the ends of the tracks so it wouldnt accidentally fly off the ends. Both lenghts of track cost about $50, the 2 sets of wheels cost about $50 and the hoist was about $89. The whole project cost about $200 and a half day to put it all together. I should have done this years ago. Awesome.

Unistrut is the best by far with this kind d of hardware I've built shelves with it and it's super sturdy I'm over 300 lbs and I jumped on my shelf I made and it didn't budge .Great stuff you get whast you pay for.

I'm using these dollies with 1-5/8 SuperStrut from lowes to lift and move 12x7 350lb floating dock sections in a storage area. 6 10ft sections of SuperStrut provide me with a 60ft runway, I use two of these 4 wheel dollies with a chain fall/hoist attached to each. I can lift the docking section then move it to the front and lower it onto a open trailer, it's now a one man job.Please note if designing your system with 1-5/8 tall superstrut the clearance between the plate on these dollies and the top inside of the superstrut is very close. So close I could not find a fastener that that the dolly would not bind on. The hanging brackets that hold the superstrut are $15 each, so you would spend more on the brackets then the superstrut and the dollies combined, I temporarly mounted the superstrut in position with 1 temporary lagbolt in the center of each section of superstrut. Once all hung I marked the suport joyce's location on the superstrut.On exposed Joyce's locatons I cut up angle iron in 1-5/8" lengths, drilled a 5/8 hole towards the top on one side of the angle. Then took the superstrut down and welded the angle perpendicular to the superstrut on its top.On sections where the Joyce's were not exposed I welded a piece of metal across the top of the superstrut with 5/8 holes pre drilled on each end of the plate.At each end of the superstrut where it would be abutting to another section of superstrut to continue the track I welded a piece of the pre-drilled angle iron on top of each superstrut top where the Joyce's were open, and on the side where the Joyce's were enclosed so I could bolt the tracks together once installed.On the exposed Joyce's I thru bolted the welded angle brackets to the Joyce's on the enclosed Joyce's I lag bolted the plates with structural rated 5" screws.Less expensive by far then buying I beam, and also keeps the trellises tight to the ceiling providing more vertical clearance.

Did the job, and now my punching bag slides along a unistrut rail. Only downside is that it really doesn't allow enough clearance for Superstrut brand to also bolt the strut up (I can't speak for other brands). I used the lowest profile lags I could find and I still couldn't bolt from inside the strut along the trolley travel path. Seems like the wheels or frame could be a little bit smaller, and this would allow for the necessary clearance.Otherwise, does the job very well. Happy with the purchase, and project result.

I used a set of 4 of these in the building of my elevator in my garage and they perform flawlessly keeping my elevator exactly in place and moving smoothly.

Fits the Superstrut 1-5/8-in x 1-5/8-in, available at Lowes or Home Depot. There is, however, no clearance for lag bolts. So you must buy the hangers....$15 each, here on Amazon...." Unistrut P1834-EG Channel Trolley Track Intermediate Support Hanger Bracket". Luckily I found them at my local electrical supply, (Kelly & Hayes has them too) for 1/2 that.This works well to move heavy stuff (200lbs) in and out of my truck, on the track, with a block and tackle.I've also seen people use two tracks, and an electric winch to move patients in and out of bed. I have rare muscle disease and saw this in one of my support groups.FYI: There is also High-Profile Strut Channel (2 7/16 " highx 1 5/8) to avoid the brackets, which will fit, but shipping a 10 ft might be a problem?

I ordered 2 of these trolleys to make a movable electric hoist and they worked great. I mounted the hoist with 2 3x3 angles bolted to the trolleys. One issue I ran into was with the clearance of the rollers and the screws I used but I found SPAX 1/4" TORX Powerlag screws from Home Depot just cleared and worked well.

I'm making a sliding "barn" door for access to the area under my rear deck which I'm closing in for extra storage space. While searching for the roller hardware, I found the Unistrut trolley assembly on Amazon. As a retired Electrician, I'm very familiar with the Unistrut product line, but was surprised to find a part I hadn't seen before. I bought two assemblies. I rec'd. them quickly and, after evaluating them, decided that four would be the right amount to carry the weight of a door made of T1-11. Very solid product supplied by a reliable Amazon Store.
