I use lifts a lot as an electrician. Scissor lifts, bucket trucks, zoom boom (jlg), etc.
There are two definitions to know when dealing with these. Fall arrest and fall restraint. Fall arrest equipment stops your drop if you go over the side. Fall restraint keeps you from going over the side in the first place. Just about every authority having jurisdiction will have their own rules to follow that either supplement or go beyond federal guidelines under OSHA (federal guidelines).
My recommendation, before you buy anything, is contact your state L and I office to see what they require. Each state is different and has their own rules and requirements. You don’t want to spend money on anything until you know it’s accepted by the AHJ for the type of work or conditions you are using it for.
You also need to make sure that trucks fits those requirement and more specifically that bucket. Then you need to find out if that bucket serves as fall restraint and what is needed while you are up there. Then you need to make sure the gear you buy meets your state or county’s requirements
it’s a can of worms and requires you to do some leg work. But it beats the fines that can be assessed if an inspector drives by your job and wants to check your rig and gear. And if something does happen, and you hurt yourself or get killed, L and I will not pay, or your own insurance, if you don’t follow their rules for safety equipment and gear
Folks don’t think about this and it does bite them in the butt often. It’s not just as simple as buying some gear and thinking you are good to go. Do your homework and ask questions to the folks who write and enforce the rules in the state and counties where you work. Once you have those answers, then you can ask about gear type and manufacturers.
