Wow. Heard of that and hope the men find a way around that.

One jobs that prohibited moving the lift while in the up position, the way around that was for someone to get caught moving it while in the up position and the contractor and all of his employees getting escorted off the job.

I've been on jobs where this is a requirement and it makes the job more dangerous because it's hard to get the lift in the perfect position on the ground, so rather than wasting time going down and repositioning and going back up to see if you are centered in the work area, guys lean out of the basket and overreach.

I can see possibly not allowing the boom type lift to travel on it's wheels while you are up in the air, but to not be able to swing or extend the boom makes such a lift totally useless, how are you to get to the spot you want to work if you can't swing or extend the boom? And if it will swing or extend to next spot you want to do another task, why not swing or extend to that spot instead of stowing it, rolling the machine on it's wheels then extending/swinging again?

If I add in non productive labor/lost time I'm at 54 hrs thousand for 4" RMC Aluminum. So maybe no too bad. But like others have said the experience of the men doing the install can make that the production units sway up/down.

Again( and thank you). Is there anything I can ask my super or check on with the install/ordering of materials that might help me see if these guys have the experience( with this size conduit) and are doing the work effeciently? Thanks

Google the weight of a 10'stick of intermidiate vs grc 4".
It needs to be hung w/ appropriately rated fasteners and trapeeze- especially if its copper feeders.
Every 7' sounds typical but do not skimp on specs.

Moving the boom is permitted, you just can't move the platform

Why would a boom be able to be moved while up of a scissor is not?
Click to expand...
The jobs prohibited driving either a boom lift or a scissors lift unless the boom or platform was at its lowest position. Makes the job take much longer than if you can drive it while the boom or platform is up. Most are designed to be driven when up, but have a limit switch that sets a very low driving speed when the boom or platform is up. However on some jobs, you are not permitted to drive it with it up, even though the manufacturer says you can.

So I guess there is no way to avoid have to use an Erickson or similiar if you have mutiple conduits on a rack and you need to make 90?

Not always. It can depend on starting at the right end, or laying out from the correct side first.

Sometimes you can assemble a few pieces before fastening them in place. More manpower.
