Description



Purposes and features:

   When the crane is not working, MQQDZ series of wind rail device (hereinafter referred to as wind rail device) may automatically lower the braking plate if you move the control switch to form floating connection between the wind rail device and track. When the crane is traveling left or right under wind force, there is relative displacement between the ind rail device itself and braking plate, allowing that the supporting bar mechanism is put up under force on one side. In case of too high force, the crane is slowly disengaged from the track under the support of the supporting rod, so that the rolling friction between the crane travel and track is replaced by the sliding friction between the braking plate and track, for braking against wind. If you want to start the crane, you may only switch on the power supply and the electric drive pusher (or motor of screw rod)will automatically jack up the braking plate, allowing that is fully separated from the track surface and higher than it by a specified distance. Now, the crane may be normally operated.
