Description

Technical Field

[0001] The utility model relates to the field of forklifts, in particular to a forklift counterweight block which is convenient for installation and disassembly. Background Technique

[0002] At present, the Chinese utility model with the publication number of CN220245472U discloses a detachable forklift counterweight, including a forklift body. A first slide rail is fixed at the top of the forklift body. A first sliding seat is slidably assembled on the first slide rail. A hoist is installed on the first sliding seat. A counterweight assembly is arranged at the tail of the forklift body. An adjusting assembly used in cooperation with the counterweight assembly is further arranged at the tail of the forklift body. When the forklift body proposed by the utility model is in use, workers can move the counterweight block through the hoist and flexibly adjust the number of counterweight blocks in the counterweight box according to the operation needs of the forklift body. Moreover, when adjusting the number of counterweight blocks, there is no need to manually lift the counterweight block, and the operation is convenient, which is conducive to the smooth operation of the forklift body.

[0003] Although the existing forklift counterweight mechanism can pick up and place the counterweight block through the hoisting assembly, there are still other problems in the use process. For example, it is difficult to connect the hook with the counterweight block. Since the counterweight block is placed inside the counterweight box and there is only an opening at the upper part of the counterweight box, when connecting the hook with the lifting ring on the counterweight block, it is necessary for personnel to lean into the box to guide the hook, and the operation is cumbersome and complex. Moreover, it does not have the photovoltaic power supply function. The hoisting assembly needs to rely on electric power during operation, and the existing structure only has the connection method of wiring, which increases the loss of electric resources and has low practicability. In order to solve the above problems, we propose a forklift counterweight block which is convenient for installation and disassembly. Summary of the Utility Model
