Why APPI:  Finding a way to get burial vaults weighing up to 4,000 lbs. on and off Bicke’s flatbed delivery truck was complicated because there was no auxiliary power on the truck. However, it was equipped with an I-beam crane rail supported by stanchions at the front and rear of the bed. The limited headroom and lack of power precluded using a typical hoist and overhead trolley.

Our solution was a one-ton capacity 12 VDC hoist used in conjunction with one of our Columbia “Hammerhead” style overhead trolleys. The hoist was deck mounted next to the back of the cab and directly under the crane I-Beam. The wire rope is reeved from the hoist up through a vertical lead sheave under the beam and then through the overhead trolley sheaves and hooked to the anchor point at the outboard end of the I-Beam. This arrangement allows the vaults to be lifted until they clear the top of the truck bed and then move down the I-Beam to their transport position while remaining at a constant height off the deck.

The use of the hammerhead trolleys doubles the line pull at the hook. As a result, Bickes used a 12 VDC hoist that did not overload the electrical system on their truck.

Our Columbia Hammerhead trolleys are available in standard capacities of 1, 3, 7.5, and 10 tons. Manual positioning is standard, but chain-driven and powered options are available for indoor or outdoor use.
