AI Technical Summary
When loading and unloading goods, the existing diesel engine power system of the existing crane equipment is difficult to meet the requirements of energy conservation and emission reduction. In addition, when the emergency power supply system fails, the existing diesel engine system is also unable to meet the requirements of energy conservation and emission reduction. A high-power power source is required to start the crane equipment, which increases the equipment configuration cost, has low energy conversion efficiency, and causes energy waste and environmental pollution.
An adjustable counterweight control device is used to balance the weight of the hoisted goods, reducing the lifting load on the transport control device. A hydrogen fuel cell module is used for emergency power supply, and wasted mechanical kinetic energy is recovered. Energy is stored through an energy-saving feedback module to achieve energy conservation and emission reduction.
It reduces the oil consumption of lifting equipment, reduces environmental pollution, ensures emergency operation of equipment, and enables flexible handling and efficient energy recovery of equipment.
