Abstract: In an industrial truck, in particular a fork-lift truck, having a vehicle frame and a load pickup means (16), which can be displaced in relation to the vehicle frame, at least one wheel which is closer to the load pickup means and, at a distance from this, at least one wheel (20) which is further away from the load pickup means being provided on the vehicle frame, the wheel axle (18) of at least one wheel (20) being capable of moving in relation to the vehicle frame along a movement trajectory with a movement component which is orthogonal with respect to the standing area of the industrial truck, in addition a loading force (B), which is caused by the tare weight of the industrial truck and a load (L) which may have been picked up by said industrial truck, acting on the at least one moveable wheel axle (18), which loading force changes operationally, the at least one moveable wheel axle (18) in addition has or can have an arbitrarily variable additional force applied to it.

Abstract: Industrial truck, in particular fork lift, having an exchangeable battery block (13) and a battery case (3) which accommodates the battery block (13), with the battery case (3) having a lateral access opening (7) to slide the battery block (13) with a first end first into the battery case (3) and pull the battery block (13) with its first end last out of the battery case (3), with the battery block (13) accommodated in the battery case (3) being supported near its first end with at least one independent roller (25) on the battery case bottom (5), characterized in that that on the battery block (13) accommodated in the battery case (3), a projection (21) at the first end opposite the second end of said battery block, which projects over a front edge section (29) of the battery case bottom (5) near the access opening (7) and over the underside of the battery case bottom (5) downward, is provided as lifting abutment for a battery transport device (33), in particular a fork lift device to lift the battery block (

Abstract: The invention relates to a battery changing system comprising an industrial truck and a battery pack, which is or can inserted into a battery compartment of the industrial truck, wherein the battery pack may be inserted into a lateral access opening of the battery compartment with a first end leading into the battery compartment and may be withdrawn from the battery compartment with its first end at the rear, wherein the battery pack accommodated in the battery compartment can be supported in the vicinity of its first end with at least one rolling body on the base of the battery compartment, and at least one transport device, on which the battery pack can be accommodated. The transport device may comprise a changeable adapter, which can be aligned in a predetermined position for a battery changing operation relative to the industrial truck by means of mutually interacting alignment means.

Abstract: The invention relates to a locking mechanism for securing a battery pack (20) which is accommodated in an electrical vehicle (12), in particular in an electrical industrial truck, comprising a vehicle-side plug element (26) and a battery plug element (28), which can be plugged together with said plug element (26) and is connected to the battery pack (20). In this case, it is provided according to the invention that the mechanism comprises a locking element (32), which is arranged on the vehicle (12) and can be moved, in particular pivoted, between a battery release position and a battery locking position, the locking element (32) and the vehicle-side plug element (26) being arranged in relation to one another in such a way that the plug-type connection between the vehicle-side plug element (26) and the battery plug element (28) can be produced and released depending on the position of the locking element (32).

Abstract: The invention relates to a battery changing system, comprising at least one first industrial truck (12), at least one battery pack (14, 20, 42), which is or can be inserted into a battery compartment (16) of the first industrial truck (12), wherein the battery compartment (16) has at least one lateral access opening (18) for inserting the battery pack (14, 20, 42) with a first end (54) leading into the battery compartment (16) and for withdrawing the battery pack (14, 20, 42) with its first end (54) at the rear from the battery compartment (16), wherein the battery pack (14, 20, 42) accommodated in the battery compartment (16) can be supported in the vicinity of its first end (54) with at least one rolling body (52a, 52b) on the base (48) of the battery compartment (16), and at least one transport device (24), on which the battery pack (14, 20, 42) can be accommodated and can be moved away from and towards the industrial truck (12).
