Description

Technical Field

[0001] This utility model belongs to the technical field of engineering machinery and counterweight devices, specifically relating to an engineering machinery and counterweight device. Background Technology

[0002] Counterweights are heavy objects used to balance a moving part of a machine. Forklift counterweights refer to the balance weights placed at the rear of the forklift to ensure that the forks can lift the corresponding load. This ensures that the rear wheels of the forklift have sufficient traction with the ground, allowing the forklift to drive and steer normally. The main functions of counterweights include improving the stability of the forklift, enhancing maneuverability, increasing load capacity, and protecting the safety of the driver.

[0003] Currently, forklifts are mostly equipped with counterweights at the rear to ensure that the rear wheels have sufficient traction with the ground when the forklift is moving goods. However, it is not possible to guarantee that the weight of the goods being moved is consistent each time the forklift is working. The existing counterweights are installed in fixed positions, and the center of gravity of the forklift can only be adjusted by adjusting the weight of the counterweight. Each time a suitable counterweight is moved, it is necessary to reinstall a counterweight of appropriate weight, which is inefficient. If it is not adjusted in time, the stability of the forklift cannot be guaranteed, and the safety is poor.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide an engineering machinery and a counterweight device.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.
