AI Technical Summary
Existing electro-hydraulic windproof brakes are prone to motor submersion and hydraulic device oil leakage in port gantry cranes due to storm surges, posing safety hazards.
The movement of the piston is controlled by an airbag, which drives the movement of the iron wedge assembly by inflating and deflating the airbag. This replaces the traditional electric windproof iron wedge hydraulic device and avoids the problems of oil leakage and water immersion of the motor in the hydraulic device.
This completely solved the problem of oil leakage and seepage in the hydraulic system, ensuring stable operation of the equipment under harsh weather conditions and preventing damage to the motor.
