Forklift truck

Abstract

The invention relates to a forklift truck, comprising a front frame, a rear frame, a working device, a steering room, an engine, a torque converter, a transmission gear, a front drive bridge and a rear drive bridge. The forklift truck is characterized in that the working device and the steering room are mounted on the front frame; the engine, the torque converter, the transmission gear and a balancing weight are mounted on the rear frame; a lift mechanism of the working device is an eight-bar mechanism; brake devices are symmetrically mounted at both ends of the drive bridge; and each of the brake devices consists of a brake disc and three brake calipers which are evenly distributed along the circumference of the brake disc. The forklift truck has the advantages of wide vision for drivers, stability in cargo loading and unloading, high quality and working efficiency, reliability in braking and multiple functions.

Description

technical field [0001] The invention relates to a construction machine, in particular to a forklift. Background technique [0002] Existing forklift trucks, such as the forklift trucks described in the Chinese patents whose application numbers are 200910111391.3 and 201110217317.7, have working devices installed on the front frame, and cabs, engines, torque converters, gearboxes, and counterweights are installed on the rear trucks. on the shelf. These forklift trucks exist together: first, the cab installed on the rear frame and the working device installed on the front frame will rotate each other and the front and rear distance between the two is relatively large, resulting in the driver's field of vision being relatively narrow. Poor, thus reducing the quality of work and work efficiency; Second, the brake device is composed of a brake disc and two brake calipers, a total of four brake discs and eight brake calipers in the vehicle, under heavy load (Generally refers to ...

Problems solved by technology

These forklift trucks exist together: first, the cab installed on the rear frame and the working device installed on the front frame will rotate each other and the front and rear distance between the two is relatively large, resulting in the driver's field of vision being relatively narrow. Poor, thus reducing the quality of work and work efficiency; Second, the brake device is composed of a brake disc and two brake calipers, a total of four brake discs and eight brake calipers in the vehicle, under heavy load (Generally refers to the weight of the loaded cargo exceeding 20 tons) When driving fast or parking on a ramp, its braking force can no longer meet the requirements of rapid and reliable braking, and there are potential safety hazards; third, the machine has a single operation function

In addition, the forklift truck described in the Chinese patent application number 200910111391.3 has a gantry-type lifting mechanism with a short front suspension distance, which is inconvenient for cargo loading and unloading; the forklift truck described in the Chinese patent application number 201110217317. The mechanism is a six-link structure. When loading and unloading cargo, the inclination angle of the cargo will change accordingly with the change of the lifting height, and the stability of the cargo will decrease.
