Thread: Hoist

There is no crossbar as such, or gantry. The roller doovy clamps over any of the 4 roof trusses, anywhere along. Pictured it is on the 2nd truss, in the middle, approx 100mm from the vertical support which goes to the pitch of the roof.
The trusses are 28mm heavy wall pipe.

The black vertical supports are moveable, 2" tube, heavy gauge angle approx 8" long to spread the load up top and 100x100 feet on 1" threads to adjust the height. They lock in without the need for bolts by adjusting the height a bit bigger and wedging them in. This means i can lift almost anywhere in the shed and doing engines there is only 900mm 'unsupported' to each big vertical beam. (Dont forget the support that goes upwards as well)

There is also supports going back to the previous truss to stop them pulling backwards (and hold shelving!)


7m-ge fully dressed weighs 220kg, i have lifted this well over 20 times using the rig with no issues. The only time i ever bent a roof beam was trying to lift my old Pitts lathe out of the trailer, which was closer to 1000kg

Chain blocks have far more reach / depth, but I think you are dealing with an 8' ceiling? Not much point having a 20' drop. Plus on a convential chain fall you have the control chain. Gravity is a bitch, if your loading stuff onto a granite plate, that control chain wants to be dangling 'just" there.

The joy of a lever / come-a-long, you have to flick the lever for up or down, otherwise the ratchet just kicks in. So you know the direction you want.

I'm going to admit right know, I'm totally dyslexic, on a chain block, when you have two chains hanging down. I can be lowering somthing down, turn around to to find a tool, then pull the wrong chain. I can't help it.

I've several lever styles here. Drop in when you are this side of town. We can pick something heavy up and have a play. Right now they have never been so cheap. I had cause to buy a 750kg for a recent job. In Beaver brand, that went around $170

Regards.

Phil,

The ceiling height is around 2.4 - 2.7 so I don't have much to play with, particularly if I have to lift the mill. I want to make my gantry height adjustable so I can lower it to get it through the garage door and make it higher if I need to get something off the trailer. So the come-along-type type with the shorter chain is probably all I need. I might but a bid on the one you mentioned.

G'day Christian.

Did you see the gantry at the local pilots place? I believe that's for sale, and its getting closer to going, going, gone time*. That must be some where around the 2.7m height, and has the two hydraulic rams, for height adjustment. It would certainly be a good start, even if it needed modifications. It has castors all ready.

Don't forget with the come-a-long type. Use it up side down, the hook of the chain end onto the top beam, then the handle is just over what ever you are lifting.

Regards Phil.

G'Day Phil,

Ah yes, I think the pilot described it as the "russian tank of gantries". I was thinking of something less big boned... but i'll chase him up.

So that is the reason for the bolt on pulley bracket. Sounds like a good setup then. Bit hard to tell from the pics.

Have never been sure that electric winches were safe to use for hoisting. Most come with a warning that they are not suitable for this purpose. The brake is only there to hold a load when winching, and is not rated for prolonged lowering. The little fibre brake disc in them has been known to overheat and/or disintegrate when lowering heavy loads, and it is a scary moment when you find a load descending in angel gear!
A real hoist has a brake unit on its motor, and not just a small worm activated disc on the gear train. If something goes amiss with this your insurance company will disown you vey quickly. Just my opinion, Combustor.

Nah, its more the Rolls Royce Phaeton of gantries. But it will fit both underneath a standard garage door and telescope up to 2.7 and 3 metres in height in two stages. And comes with a large CO2 fire extinguisher!
