I have to admit I have never used one............not wanted to either!
I have always found plenty of
Step Up Devices close to hand if I need one: A
Double or
Clip attached to the
Standard......a Butt, maybe.......but seeing as we are expected to work to SG4.05 now we probably have a
Single Handrail running the length of the Lift already.....
...........so, as most Lifts we erect these days are usually 6'6" it's quite easy to jump up on your Handrail, reach up and fix Doubles to whatever Standards you have there ready for the next Lift.......
should be at least every other one if you have Staggered correctly..........and the Doubles you fix should be a reasonable height for your next Safety Handrail......
From there it's plain sailing: Slide a Long Un up over the Trannies you have already fixed...........jump up on the Handrail (
preferably with your mate the other end)...........and slap it into the Doubles you have already fixed above. That gives you a start when you climb to the next Lift......and then you continue sliding tubes into the Doubles you have already fixed as you work your way along........
