Would like to attach collapsible/fold out cage to rear of forklift to allow unloader/helper to ride along while operator moves cargo from truck to work-site. Assume cage meets same safety standards as those used to lift maintenance workers on forks/front of forklift. Does anyone have experience with something like this? Any comments re: OSHA or other safety regs that might prohibit? Comment in forum or email me at budcoh at columbus dot rr dot com.
