    I stripped some 10AWG copper and wrapped it around the frame and it lays on the floor pretty stealthy under the stepladder in the rear. So far no shock but I have to investigate further.

    Silicone Rubber Strips for Static Grounding

    I ran into this on our Forklifts and Scissors Lifts. As others have said, dragging a chain or copper wire would work since it is a rental. Others may be reading this that are having trouble on their own equipment. I purchased Shielding High-Temperature Silicone Rubber Strips through McMaster. It solved the problem. You could use this on a Rental if you used some sort of removable Clamp.

    Shocking has to do with ground resistance also: it has to be below a certain limit to avoid shock even with your above arrangement.

    I've seen this happen on older lifts that use diode logic for controlling the hydraulic solenoids. I'm assuming that since they're rental lifts they're newer and don't use diodes but it's something to consider. I have personally experienced this, the shock would occur when holding the handle and the cage. You would received the shock as soon as you stopped operating the lift. I figured one of the diodes was bad, this caused a flyback from the magnetic field collapsing.
    The world is round, you will get there no matter what path you take.

    After driving a scissor lift on carpet on the 38th floor of a high rise, the static shock was strong enough to singe hair.

    On a hanger remodel job, the flooring contractor resurfaced a floor with epoxy right after the demo phase because it fit with their schedule. The general had to put down plastic 5 mil then put plywood on top of that. We were arcing up to 1.5 inches from static. That job was 12 years ago and I still shy away from touching metal when I'm in a lift. BTW, some older aircraft like a DC-6 have leather straps for grounding.
    Back on your heads boys, break is over.

    For the infinitesimal amount of money involved, you could install it permanently and do the next renter a small favor.

    Sure, why not? Leather is skin, and skin is conductive. Come to think of it, I probably have a few old leather belts kickin' around that are overdue to be repurposed.
