Im an arborist and and a licensed crane operator. To clear things up for you guys, OSHA does forbid that we ride the ball, they actually specify that we tie into a carbine at the boom tip. Is this practical???Should we fallow this regulation????HMMMM, what do you think??? We have our own 40 ton terex and do crane work a few times a week, and i don't think there is anything wrong with tyeing into the ball.
Hows it going diltree, this is what i think...
I don't see what difference tyeing into the boom tip as apposed to the crane hook makes.
The crane hook, as far as i know, does not have a mechanism which allows the crane driver to drop loads at the touch of a button or anything, so if it cant carry a climber with virtually no weight on the system how can they justify lifting large loads over buildings etc. The crane hook always has a self locking clip, and if the climber feels the need, they can tape the clip closed. The climber should have two points of contact when riding the crane, eg rope through the hook, lanyard through the accessory strop loop.
A strict and complete hazard management plan should be written and shall be followed to avoid any form of harm, this includes a hazard identification and control form which is filled in and signed by everyone.
Notification and approval by osh inspector on big jobs is required.
An experienced and/or trained dog-man must work and communicate between the crane driver and climber
Chains other than strops are to be used on the actual load
Many factors which both the crane driver and contractor must sort and be aware of include things like; site and ground conditions, public and traffic management, electrical conductors, choosing a crane for the job, SWL of crane, slings, ropes and chains. And many more
It comes down to people being alert and aware of the situation at hand as well as keeping a cool head.
