Abstract
An apparatus for removing and intalling batteries from equipment, such as a lift truck. The apparatus includes a mobile frame and a bed is mounted for vertical movement on the frame so that the bed can be moved to a position at the same level as the floor of the battery compartment in the lift truck. A pair of parallel drive chains are mounted for endless travel on the bed, and a coupling is carried by the chain and is adapted to engage a strap which encircles the base portion of the battery. By operating the chains, the battery can be withdrawn from the vehicle onto the bed, and the unit carrying the battery can then be moved to a recharging area where the battery is pushed from the bed onto a recharging rack. To raise and lower the bed, a floating cylinder unit is located within the upper horizontal frame member and is connected to one side of the bed. The cylinder unit acts in conjunction with a crossover levelling mechanism to raise and lower the bed while maintaining the bed in a level attitude regardless of the position of the load on the bed.
