Forklift and forklift control method

Abstract

The present invention relates to a forklift and a forklift control method. A forklift and a forklift control method according to the present invention adjust the fork / mast inclination with reference to the coefficient of friction and also refer to geographical information such that the fork / mast inclination can be adjusted adequately right before the forklift exits from or enters a slope. In addition, when a degree of danger does not decrease even after the fork / mast inclination is tilted backwards to the largest extent, the output of the forklift is reduced, or the brake is actuated, thereby reducing the traveling velocity of the vehicle and substantially reducing the danger of the load falling off.

Description

technical field [0001] The present invention relates to a forklift and a control method for the forklift. More specifically, the present invention relates to a forklift and a control method for the forklift capable of preventing a load from falling during travel. Background technique [0002] Generally, forklifts are used to move loads. In more detail, forklifts move along travel paths and carry loads. [0003] On the other hand, a forklift receives power from a power source to operate a hydraulic system, and the hydraulic system generates hydraulic pressure. The forklift travels by means of hydraulic pressure or an engine or a motor, or lifts the fork by hydraulic pressure. In addition, the fork can be equipped with a mast, which can be tilted forward and backward in the forklift. The previously described power source may be an internal combustion engine or an electric motor. [0004] On the other hand, the load is loaded on the pallet, and the fork of the forklift is i...

Problems solved by technology

[0008] On the other hand, the load is arranged in front of the forklift, so when driving forward, the driving path may be blocked by the load in the field of vision.

Therefore, there is a problem that it is difficult to ensure the information on the driving route, that is, the field of view.

[0009] Therefore, in the past, it was difficult to adjust the inclination angle of the mast of the forklift truck at an appropriate time point. In addition, there were situations where it was not known to what extent the inclination angle of the mast was adjusted.

In particular, proper control of the inclination angle of the mast will be seriously deviated due to the proficiency of the operator. If the operator is an unskilled operator, there may be situations where the inclination angle of the mast is incorrectly set.

Furthermore, due to the wrong judgment of the operator, the inclination of the mast may be controlled in a completely unexpected wrong direction. In this case, there is a possibility that the load may fall.
