Embodiment Construction

[0024] figure 1 An industrial truck according to the invention is depicted. The truck can be any type of industrial truck, such as a fork lift truck, a stacker truck or a reach truck.

[0025] The industrial truck 1 includes a frame 2 . The front of the frame 2 extends into two support arms 3 on which support wheels 4 are arranged. The rear of the frame supports a motor housing 5 in which the electric motor and hydraulic system (not shown) are housed. The electric motor drives drive wheels (not shown) arranged below the frame. The hydraulic system powers the raising and lowering of the load carrier of the truck, as explained further below. The truck may also comprise space for the driver, eg a seat or a platform, and means for maneuvering the truck, eg a joystick or a steering wheel.

[0026] The truck also includes a first lifting mast 6 . The mast can be a fixed mast or a telescoping mast. In the case of a fixed mast, the mast comprises a pair of uprights 7.1, 7.2. T...

Abstract

The invention relates to an industrial truck (1) comprising a first mast (6) comprising two uprights (7.1; 7.2) and a first and a second load carriage (9; 14) arranged to be independently moved in the vertical direction wherein a second mast (12) is arranged between the uprights (7.1; 7.2) of the first mast and that the first load carriage (9) is arranged to be moved along the first mast (6) and the second load carriage (14) is arranged to be moved along the second mast (12).

Description

technical field [0001] The invention relates to an industrial truck comprising two load carriages which are independently movable on two separate masts. Background technique [0002] In warehouses, goods are usually unloaded and placed on pallet racks until they are required for sale or further processing. When orders arrive, stacker trucks are dispatched to pick up the goods and deliver them for further transport or processing. Loading and unloading goods in this way is labor-intensive, since each transfer and pick-up order requires the operation of a truck and a driver. [0003] In order to increase the operational efficiency of cargo handling in warehouses, industrial trucks with a double loading capacity have been developed, for example so-called support arm stackers with a double loading capacity. In this type of truck, a first load is lifted on a first set of forks, which are movable on a mast. Thereafter, the second load is lifted on the support arm of the truck wh...
