Abstract
A frame for a battery-operated industrial truck includes a forward frame segment, a middle frame segment, and a rear frame segment. The middle frame segment is designed to hold a battery block and is provided with a frame top opening and a frame side opening through which the battery block can be inserted in the frame and removed again. To make it possible to easily replace the battery block using different battery replacement systems, the invention teaches that the frame side opening is connected without interruption to a frame bottom opening of the middle frame segment. To increase stability, the middle frame segment has at least one deflection-proof and torsion-proof longitudinal beam that connects the forward frame segment with the rear frame segment, and is preferably realized in the form of a hollow profile.
