AI Technical Summary
When existing cranes rotate at high speeds, the increased inertia causes the device to tilt, which may lead to serious accidents such as tipping over.
The expansion rod is moved by the push rod, which makes the rubber block contact the base plate, increasing the contact area between the vehicle and the base plate. The expansion rod and the buffer box are moved by the hydraulic rod and the threaded rod system driven by the motor, thereby improving stability.
It effectively reduces the possibility of crane tilting, increases the stability of the device, ensures that the traveling vehicle is accurately positioned when stopped, and prevents tipping over.
