Embodiment Construction

[0018] figure 1 The truck shown has a drive section 10 with a joystick 12 for steering the vehicle by an operator. Arranged on the drive part 10 is a lifting frame 14 which has two spaced-apart profiles 16 , 18 which are connected to each other at their upper ends by means of a cross member 20 . The lifting frame 14 is fixedly connected to the drive part 10 or the frame of the drive part. The forks 22 are guided vertically in the lifting frame 14 and are moved vertically by a lifting device (not shown). The pallet fork has a carrier slide 24 which is guided in guide rails of the profiles 16, 18, wherein only one guide rail 26 is figure 1 visible in . The guidance is carried out by means of rollers on the carrier carriage 24 which are guided in guide rails, wherein in figure 1 Only two rollers 28 are visible. Preferably at least two vertically supported guide rollers are provided in each profile 16 , 18 . The fork arm 30 is connected to the carrier slide 24 . The yoke ha...

Abstract

The invention relates to a high-lift industrial truck which comprises a driving part and a lift frame. The lift frame has at least two mast profiles that are parallelly spaced apart and are connectedby at least one traverse beam and are provided with bearing sliders for a fork. A fork arm is mounted on the bearing slider. The fork arm has a top end (free end) and a root part (connecting part on the bearing slider). The high-lift industrial truck has a lifting device for the fork. Each mast profile has at least two rollers which are spaced in a height direction for guiding the bearing slidersin a guide rail. The guide rail has rolling surfaces which are separated. The rolling surfaces are approximately perpendicular with the forks, wherein in a section which is next to ground in the guiderail, the distance between the rolling surfaces is larger than the distance of the rolling surface in a section above the section. As such, the tip end of the fork arm is lower relative to the root end when at least the lower roller of the at least two vertically space rollers is located in the lower section near the ground.

Description

technical field [0001] The invention relates to a high-lift truck according to claim 1 . Background technique [0002] Pallet trucks are known as low-lift and high-lift pallet trucks. In high-lift trucks, the loaded goods can be lifted to a predetermined height in order to be able to transport them into racks or the like. High-lift trucks therefore have a lifting device with lifting columns. The lifting column comprises at least two approximately parallel spaced column profiles, which are connected to one another by at least one transverse connection. In the lifting column is guided the carrier carriage of the fork, which can receive the load via the fork arm. For each column profile, the carrier carriage has at least two rollers spaced apart in height, which are guided in slide rails of the profile. The cross-section of the column profile is therefore preferably U-shaped, as a result of which two spaced-apart running surfaces are obtained, which run approximately perpen...
