Abstract

A handling device is provided for a battery block (1) of an industrial truck having a lateral battery extraction opening. The handling device includes a pallet truck (3) and a battery receptacle (4) mountable on the pallet truck (3). The battery receptacle (4) on the pallet truck (3) can be inserted underneath a battery block (1) that is located in the industrial truck, whereupon the battery block (1) can be lifted and removed from the industrial truck. The battery receptacle (4) has a load-bearing frame by means of which the weight of the battery block (1) can be supported on the tines of the fork of the pallet truck (3). In one development, the handling device includes a battery tray on which the battery block (1) can be set down by the battery receptacle (4) that is located on the pallet truck (3).

Claims

1. A handling device for handling a battery block of an industrial truck having a lateral battery extraction opening and an at least partly open bottom, the handling device comprising:

a pallet truck having at least one fork configured to enter into the lateral battery extraction opening; and

a battery receptacle removably mountable on the pallet truck,

wherein the battery receptacle includes a load-bearing frame, by means of which the weight of the battery block can be supported on the fork of the pallet truck,

wherein the handling device is configured such that the battery receptacle when located on the pallet truck is movable into the at least partly open bottom of an industrial truck underneath a battery block installed in the industrial truck so that the battery block can be lifted and moved laterally out of the industrial truck on the battery receptacle,

wherein the battery receptacle includes a stop for the battery block to determine a depth to which the pallet truck can be inserted underneath the industrial truck,

wherein the battery receptacle includes at least one guide element fastened to the frame of the battery receptacle, by means of which the battery receptacle can be fixed in position in a lateral direction relative to the fork of the pallet truck, and at least one support element fastened to the frame of the battery receptacle, by means of which support element the battery receptacle can be placed on the floor or the ground by lowering the fork of the pallet truck,

wherein the guide element and the support element are formed by a single component, and

wherein the guide element and the support element comprise a flat top portion having a bottom configured to extend over a portion of a top of the fork and a downnwardly-directed flat component extending at right angles to the top portion, the top portion and downwardly-directed portion forming an open, inverted L-shaped groove configured to engage an inner portion of the fork.

2. The handling device as claimed in claim 1, wherein the load-bearing frame of the battery receptacle comprises rectangular hollow sections.

3. The handling device as claimed in claim 1, wherein the handling device comprises a battery tray on which the battery block can be placed by means of the battery receptacle located on the pallet truck.

4. The handling device as claimed in claim 3, wherein the battery tray comprises a longitudinal beam which, as the battery block is being set down, is located between spaced tines of the fork of the pallet truck.

5. The handling device as claimed in claim 4, wherein the battery tray comprises a crossbeam which, as the battery block is being set down, is located in front of the fork of the pallet truck and underneath the battery block.

6. The handling device as claimed in claim 5, wherein at least one of the longitudinal beam and the crossbeam are made of wood.

7. The handling device as claimed in claim 3, wherein the battery tray comprises a crossbeam which, as the battery block is being set down, is located in front of the fork of the pallet truck and underneath the battery block.
