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

[0007] Further, the hydraulic device is provided with two, and the two hydraulic devices are arranged in parallel on the cab bearing platform.

[0008] Further, 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 with the cab moving platform.

[0009] Further, the cab moving platform below the top protection frame is a cab.

[0010] Further, the guide rail mechanism comprises: a linear guide rail and a sliding block installed on the linear guide rail, the linear guide rail is fixed on the cab bearing platform through bolts, and the sliding block is fixed on the cab moving platform through bolts.

[0011] Further, the steering mechanism and the wheels are arranged in the cab bearing platform, and the steering mechanism controls the steering of the two wheels.

[0012] Further, the steering wheel in the steering mechanism is arranged in the cab moving platform, and is used for controlling the steering of the wheels.

[0013] Further, the counterweight is arranged on the cab bearing platform.

[0014] Further, the counterweight is arranged on the cab moving platform.

[0015] The beneficial effects of the present application are as follows: the cab of the forklift truck is designed to be movable in the direction of the slide rail, and under different load conditions, the relative position between the center of gravity of the whole vehicle and the load center of the forks can be changed by adjusting the position of the cab, so that the variable rated load can be realized. Relying on this function, the distance between the center of gravity of the whole vehicle and the load center of the forks can be changed with the change of the position of the cab under the condition that the distance between the load centers is unchanged, and the position of the cab can be adjusted according to the actual weight of the goods to be loaded, so that the goods of different weights can be more stably loaded, and the stability of the whole vehicle is greatly improved. Moreover, the portal system is fixed on the cab moving platform, and the lifting height of the goods can be adjusted by the position of the cab, so that an additional lifting height is added to the lifting height of the portal system. In addition, when the forklift truck carries the goods to move, the driver can sit at a higher position relative to the ground, so as to obtain a better field of view, reduce the blind area of the field of view, and improve the safety of the forklift truck when moving. The present application enables the forklift truck to have a smaller size and a smaller whole vehicle quality, and has a larger rated lifting capacity, so as to improve the carrying efficiency, and also has superior stability, a larger lifting height of the goods, and safer driving conditions.

[0018] In order to make the purpose, technical scheme and advantages of the present application more clear and explicit, the present application is further described in detail below by means of the drawings and examples. However, it should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the scope of the present application.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0020] like Figure 1 As shown, a novel counterbalance forklift includes: a top guard 1, a hydraulic device 2, a cab moving platform 3, a cab carrying platform 4, a guide rail mechanism 5, and a mast system 6. The cab moving platform 3 is mounted on the cab carrying platform 4 via the guide rail mechanism 5. The hydraulic device 2 is located between the cab moving platform 3 and the cab carrying platform 4 and is used to control the movement of the cab moving platform 3 on the cab carrying platform 4. The mast system 6 is installed at the end of the cab moving platform 3 and is used for inserting workpieces. It can move with the cab moving platform 3. The top guard 1 is mounted on the cab moving platform 3.

[0021] The cab supports the vehicle body, which serves as the carrier for driving and provides structural support for the cab.
