Problems solved by technology

The disadvantage of this curved shape member is that it only gives the operator little assistance when dealing with obstacles
The design also makes it difficult to roll over obstacles at an angle, meaning there is a risk of the forklift tipping over when loaded

Embodiment Construction

[0046] figure 1 A side view of a forklift truck 100 according to an embodiment of the invention is shown. The forklift truck 100 comprises a fork 102, wherein the height of the fork 102 is adjustable between a lowered position and a raised position, and wherein, at a front end 108 of the fork 102, a fork wheel bogie 106 is provided, the fork wheel bogie 106 includes front wheels 110 and rear wheels 120 . figure 1 The fork 102 in is in a raised position. The fork 102 has a fork 109 at the front end 108 . A sliding device 130 is attached to the front wheel 110, wherein the sliding device 130 is configured to slide over an encountered obstacle (not shown) and thereby lift the front wheel 110 onto the obstacle. The slide 130 is also adapted to act as a lever in cooperation with the fork 102 so that the rear wheel 120 can be lifted over an encountered obstacle. The forklift 100 may generally be a hand dolly, powered dolly, hand or electric stocker, tiller arm truck or the forkl...

Abstract

The present invention relates to a forklift truck comprising at least one fork (102, 104), wherein the fork (102, 104) is height adjustable between a lowered position and a raised position and wherein a fork wheel bogie (106) is arranged at the front end (106) of the fork (102, 104), each fork wheel bogie (106) comprising a front wheel (110) and a rear wheel (120). A slide device (130) is attached to the front wheel (110), wherein the slide device (130) is configured to be able to slide on an encountered obstacle and thereby lift the front wheel (110) onto the obstacle. The slide device (130) is adapted to act as a lever in cooperation with the fork (102, 104), such that the rear wheel (120) may be lifted onto the encountered obstacle. The invention also relates to a method for climbing an obstacle with a forklift truck (100) and a method for modifying a forklift truck (100).

Description

technical field [0001] The invention relates to a forklift truck according to the preamble of claim 1 , a method for climbing an obstacle with a forklift truck according to claim 9 , and a method of retrofitting a forklift truck according to claim 12 . Background technique [0002] Forklifts are typically used to handle indoor loads on flat, even surfaces. However, there are situations where loads need to be transported over irregular surfaces, such as outdoors in urban environments. Obstacles such as pavement, thresholds, curbs, doorsteps or the like may thus be encountered and based on the height / size of the obstacle and the weight of the load it may be difficult to steer the forklift truck over the obstacle. This is especially problematic when using a forklift where the forks are the first to encounter an obstacle. Obstacles of this type may require additional force from the operator to operate the forklift or the operator may have to manually lift the forks of the fork...
