The brake is arranged on the motor shaft, and is integrated with the driving braking, the parking brake and the emergency brake, which greatly simplifies the structure of the brake and the hydraulic control circuit. The brake is provided with a braking force by a compression spring, and the brake is released from the hydraulic oil, so that the brake can be safely and safely under the condition of the failure of the engine and the failure of the hydraulic pipeline.
Through the calculation of braking brake needs to provide the maximum braking force of the compression spring were traditional design and calculation, and using ptimization toolbox to brake when the length of the spring as the optimization objectives are optimized, the optimization effect is obvious, and significantly improves the brake of storage capacity.
Crane Hydraulic Thruster Brake has the characteristics of simplified structure, reduced volume, reduced quality of the spring, smooth running, good thermal stability, no mechanical degradation problem, and good water stability performance. To sum up, the utility model can improve the comprehensive performance of the brake.
