Abstract: An industrial truck (1) has a drive section (2) and a movable load section (4). The load section (4) has at least one wheelarm (5) with at least one load roller (6) rotatably mounted in a load roller carrier (12) which is mounted by a swivel bearing (13) on the wheelarm (5). The swivel-bearing (13) is a bearing pin (20). A linkage (10) is connected with the load roller carrier (12) by a coupling pin (21). The load roller carrier (12) has two outer bearing levers (12a, 12b) with bearing flanges (32a, 32b) for mounting the bearing pin (20) and bearing flanges (33a, 33b) for mounting the coupling pin (21), and an additional web (30) located between the outer bearing levers (12a, 12b) and having a bearing flange (32c) for mounting the bearing pin (20) and/or a bearing flange (33c) for mounting the coupling pin (21).

Abstract: An industrial truck (1) has a drive section (2) and a load section (4) movable relative to the drive section (2). The load section (4) has at least one wheelarm (5) having at least one load roller (6). The load roller (6) is rotatably mounted in a load roller carrier (12) swively-mounted by a swivel bearing (13) on the wheelarm (5). In the vicinity of the swivel bearing (13), on the upper side of the wheelarm (5), there is an entry guide (20). The guide (20) includes at least one roller (21; 22; 23; 24) rotatably mounted on the wheelarm (5) and projecting upwardly beyond a load-bearing surface (LF) of the wheelarm (5). The swivel bearing (13) of the load roller carrier (12) includes a bearing pin (25). The at least one roller (21; 22; 23; 24) is rotatably mounted on the bearing pin (25).

The load section (4) has at least one wheelarm (5) with at least one load roller (6). A linkage (10) is connected with the load roller (6). A lever system (11) activates the linkage (10). The lever system (11) comprises a first lever (15) swivelably mounted at a first bearing point (16) on the drive section (2) and swivelably mounted at a second bearing point (17) on the load section (4). A second lever (20) swivelably mounted at a bearing point (21) on the load section (4) and coupled at a coupling point (22) with the linkage (10). An intermediate lever (25) is connected at a coupling point (26) with the first lever (15) and at an additional coupling point (27) with the second lever (20).

Abstract: An industrial truck, in particular a counterbalanced front-forklift truck, is provided which can be operated both manually and automatically and has a fork to handle pallets and loads located thereon. The forklift truck is equipped for automatic operation with a control system which can be brought into active connection with the vehicle drive system, the vehicle steering system, the vehicle braking system or the movement control system for the fork.

Abstract: A lift truck has a tractive-power electric motor, an electric motor which actuates a pump for the hydraulic circuits, and batteries which supply the electric motors. In order to obtain a long working life as well as reliability and a high performance, the tractive-power motor or both motors are asynchronous and there are provided devices for sensing the angular positions and angular velocities of the motors and an electronic control unit connected to the sensor devices for controlling the power supplies to the motors in dependence on required velocities for the motors and on the basis of data provided by the sensor devices.

Abstract: An electric drive system in lift trucks has, for driving the lift truck driving wheels, at least one separate excitation electric motor provided with a stator and a rotor which are energized independently of each other by means of an electronic drive and control unit; by this arrangement, space can be saved on the lift truck and the lift truck can be rendered reliable, low in running cost, adaptable to varying load conditions, and adjustable as regards its operational parameters.
