Abstract: An industrial truck (1) has a compartment for an energy supply unit (5) having a lateral opening (6). A retaining apparatus (15) is provided for fixing the energy supply unit (5) in position in the lateral direction and a contacting apparatus (20) is provided for the electrical connection of the energy supply unit (5) with the industrial truck. The retaining apparatus (15) can pivot between a retaining position and a removal position, and a vehicle-side coupling element (20b) of the contacting apparatus (20) is located on the retaining apparatus (15). In the retaining position of the retaining apparatus (15), the vehicle-side coupling element (20b) is above the energy supply unit (5) and in the removal position the retaining apparatus (15) with the vehicle-side coupling element (20b) is outside the range of motion of the energy supply unit (5).

Abstract: A chassis for a battery-operated industrial truck has a center chassis section (1) configured to hold a battery block. The center chassis section (1) is open on top, has a forward transverse wall (5), a rear transverse wall (6), an open side wall (7) provided with a lateral battery compartment opening (B), and a closed side wall (8) which is at a distance from the open side wall (7) in the transverse direction of the chassis. The center chassis section (1) has a chassis bottom (9) in the form of a rigid and torsion-resistant hollow body.
