[0002] Forklifts are important short-distance special engineering vehicles in the logistics industry, and are widely used in material storage, factory workshops, stations, airports, ports, etc. Each scenario requires forklifts to operate safely and efficiently, and even some specific environments require forklifts to have a smaller size and be able to carry heavier goods.

[0003] Therefore, there is an urgent need for a forklift that is small in size, has a strong carrying capacity, and can achieve safe and stable operation requirements. Summary of the invention

[0004] In view of the problems existing in the above-mentioned prior art, the present invention provides a new type of counterbalanced forklift, which has a small size, a strong carrying capacity, and can achieve safe and stable operation requirements, thereby solving the above-mentioned problems.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a new type of counterbalanced forklift, including: an overhead guard, a hydraulic device, a cab moving platform, a cab bearing platform, a guide rail mechanism and a gantry system. The cab moving platform is installed on the cab bearing platform through the guide rail mechanism. The hydraulic device is arranged between the cab moving platform and the cab bearing platform, and is used to control the movement of the cab moving platform on the cab bearing platform. The gantry system is installed at the end of the cab moving platform, and is used to insert workpieces and can move with the cab moving platform. The overhead guard is installed on the cab moving platform.

[0006] Furthermore, an inclined mounting surface is provided at the upper end of the cab bearing platform, and a mounting surface corresponding to the mounting surface of the cab bearing platform is provided at the bottom of the cab bearing platform.

[0007] Furthermore, two hydraulic devices are provided, and the two hydraulic devices are arranged in parallel on the cab bearing platform.

[0008] Furthermore, the hydraulic device is a hydraulic cylinder, the cylinder body of the hydraulic cylinder is installed on the cab bearing platform, and the piston rod of the hydraulic cylinder is connected to the cab moving platform.

[0009] Furthermore, the cab moving platform below the overhead guard is the cab.

[0010] Furthermore, the guide rail mechanism includes: a linear guide rail and a slider installed on the linear guide rail, the linear guide rail is fixed to the cab bearing platform by bolts, and the slider is fixed to the cab moving platform by bolts.

[0011] Furthermore, a steering mechanism and wheels are provided in the cab bearing platform, and the steering mechanism controls the steering of at least two wheels.

[0012] Furthermore, the steering wheel in the steering mechanism is arranged in the moving platform of the cab to control the steering of the wheels.

[0013] Furthermore, a counterweight for balancing is provided on the cab bearing platform.

[0014] Furthermore, a counterweight for balancing is provided on the moving platform of the cab.

[0015] The beneficial effects of the present invention are as follows: the forklift cab is designed to be movable in the direction of the slide rail. Under different load conditions, the relative position of the vehicle center of gravity and the fork load center can be changed by adjusting the position of the cab to achieve a variable rated load. Relying on this function, the position of the cab can be adjusted. Under the condition that the load center distance remains unchanged, the distance between the vehicle center of gravity and the fork load center can change with the change of the position of the cab. The position of the cab is adjusted according to the actual weight of the cargo to be loaded, so that cargo of different weights can be loaded more stably, greatly improving the stability of the vehicle. In addition, the gantry system is fixed on the cab mobile platform, and the lifting height of the cargo can be adjusted by the position of the cab. On the basis of the lifting height of the gantry system, an additional lifting height is added; in addition, when the forklift carries cargo for maneuvering, the driver can sit at a higher position relative to the ground, obtain a better field of vision, reduce the blind spot of vision, and improve the safety of the forklift during maneuvering; this invention enables the forklift to have a smaller body and vehicle mass, with a larger rated lifting capacity, thereby improving the handling efficiency, and also has a more superior stability performance, a larger cargo lifting height, and safer driving conditions.
