While designed for pianos these dual dollie trucks are a great solution for moving gun safes, appliances, vending machines, and many other uses. Especially designed with a spring-loaded plunger that allows swivel wheels to be locked for one-person operation or swivel in the unlocked position for two person operation.
Simply place one truck at each end of the load, fasten the straps and press the foot-lever at each end to raise load for moving. The handles fold out of the way when not in use. Comes with 4 7′ straps to hold your piano, organ, or other load in place. The casters “fully retract” off the floor to allow your load to rest on its own weight, will not skid or roll while moving.
