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 By operating the chains, the battery can be withdrawn from the vehicle onto the bed, and the unit carrying the battery can then be moved to a recharging area where the battery is pushed from the bed onto a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.

Abstract: A device for transferring load units comprises a transfer apparatus for transferring such load units in an elevated condition between first and second carriers each having at least two upwardly open channels extending transversely to the longitudinal direction thereof, the channels being bridged by the load units when located on the carriers, the transfer apparatus being arranged on the second carrier and comprising at least two separate arms each having lifting devices and being displaceable from the channels of the second carrier to the channels of the first carrier and vice versa transversely to the longitudinal direction of the carriers, the channels of the second carrier housing the arms when inactive.

Abstract: A positioning system for a roller cart adjacent a transfer cart in a roller storage and retrieval system of a printing plant has a positioning screw at the pickup station where rollers are transferred between the pickup cart and the transfer cart. This positioning screw has a longitudinal axis extending parallel to the path followed by the pickup cart at the station and is formed with a pair of screw formations which are of opposite hand and which are axially spaced from each other with a gap between their inner confronting ends. An entrainment element on the cart is engageable with these screw formations and can fit between the inner ends thereof. The pickup cart then can be positioned in the station and the screw rotated to displace this cart so that the entrainment element is moved into the space between the ends, for exact positioning of the pickup cart at the station.

Abstract: An attachment device for a fork lift and a support structure, such as a truck bed, includes a track on a truck bed. A carriage engages and is movable along the track. The carriage engaging member is mounted on the lift frame of the fork lift and is engageable with the carriage to permit the fork lift to lift itself upon the truck bed or lower itself therefrom by vertical shifting of the fork lift frame.
