Windproof wedge is based on the mobile gantry crane requirements, new development key mechanical parts brake device. It is the most important parts of mobile gantry crane to protect the safety operation.
The Windproof wedge is based on digestion and absorption of advanced technology, innovate and design a new type wind device to use during mobile gantry crane working state.
When the windproof wedge is power on, the electric hydraulic pusher start moving, the pusher push rod rises rapidly, and lift up the windproof wedge through the lever and transmission mechanism to make the mobile gantry crane working normally. When power off, with the help of spring force, the electric hydraulic pusher push rod place the windproof wedge on the track through the lever, will totally lock the part crane wheels in the case of sudden storms, play a security role.
The winproof wedge achieve action requirements through electric hydraulic pusher and lever, connecting rod mechanism, reasonable structure, reliable action. And the mobile gantry crane windproof wedge apply reasonable shape wedge and high-intensity, high hardness friction block, ensure the overall operation.
