AI Technical Summary
The existing diesel engine systems of cranes are unable to meet the requirements of energy conservation and emission reduction, requiring high-power power sources, which leads to high equipment configuration costs, low energy conversion efficiency and serious environmental pollution.
By employing an adjustable counterweight control component and sling control device, the lifting load of the lifting equipment can be reduced by adjusting the weight of the counterweight component and the switching method of the sling, thereby reducing the demand for power source and achieving energy conservation and emission reduction.
It achieves reduced fuel consumption and environmental pollution of lifting equipment without increasing the power source configuration, and the system control is simple and reliable, thus reducing the cost of equipment use.
