AI Technical Summary
The existing gate locking device is bulky and requires 2-3 people to operate. In an emergency, it cannot be unlocked quickly, which will cause the gate to fail to close in time. Forcing it to close will damage the winch wire rope.
The system employs a mobile lifting mechanism and an automatic hydraulic device for engaging and disengaging the gate support beam. By combining the hydraulic and electrical control systems, it achieves precise positioning and automatic engagement of the gate support seat. Through mechanical linkage, it reduces the need for manpower and meets the requirements for rapid unlocking in emergency situations.
It enables rapid and safe closure of the gate, avoids damage to the winch wire rope, improves equipment response speed and work efficiency, and meets the rapid and safe requirements under extreme working conditions such as flooded factory buildings.
