Abstract

The invention discloses a forklift working safety control device. The control device comprises a master controller, a fork leveling switch, a gantry height switch, a gantry angle sensor, a backward inclination action switch, an ascending action switch, a main oil circuit unloading electromagnetic valve, a descending oil circuit unloading electromagnetic valve, an engine controller and a pluralityof forklift fixing structures, wherein the master controller is arranged on a forklift center console, the fork leveling switch is arranged on an operation handle of a multi-way valve inclined linkagevalve rod, the gantry height switch is arranged on a gantry, the gantry angle sensor is arranged on an inclined oil cylinder, the backward inclination action switch is arranged on a multi-way valve assembly, the ascending action switch is arranged on the multi-way valve assembly, the main oil circuit unloading electromagnetic valve is arranged on the multi-way valve assembly, the descending oil circuit unloading electromagnetic valve is arranged on the multi-way valve assembly, the engine controller is arranged in the center console, and the multiple forklift fixing structures are arranged atthe bottom of a frame. The control device has the advantages that the working efficiency and the stability of a forklift can be effectively improved, and the safety of operators and cargoes can be protected.

Description

technical field [0001] The invention relates to the technical field related to forklifts, in particular to a forklift work safety control device and control method that can effectively improve the working efficiency and stability of forklifts and protect the safety of operators and goods. Background technique [0002] During the operation of the working device of the internal combustion forklift, the actual angle of the mast is difficult to accurately determine due to the obstacle of the driver's perspective. When the fork is not in a horizontal position when stacking goods, it is easy to cause the goods to be squeezed and damaged, and the mast of the forklift is in front. In the tilted state, the lifting operation will cause the cargo to fall and cause a safety accident. If the engine speed is forcibly increased when the mast angle cannot be determined, it will seriously affect the stability and operation safety of the vehicle; when the load of the working device is relative...
