Ed type electro-hydraulic pusher motor is installed in the lower part of the body. The interior is not immersed in oil. The rotation direction can be arbitrary. The frequency of forward and reverse rotation is high. The lifting time can be adjusted steplessly. As required, it can be equipped with regulating valves, limit switches, heaters, brake springs and damping springs.
The lifting mechanism of the double-beam bridge crane used in the workshop generally uses hydraulic brakes, which need to be adjusted according to the requirements of the work. The adjustment of the brakes mainly includes the adjustment of the braking torque and the backlash of the tiles (the thruster compensation stroke Hb). Adjustments and equal backlash adjustments. For brakes with automatic compensation, various adjustments are mainly required during initial installation (before use) and after replacement of new friction pads. If there is no abnormal phenomenon during use, generally no adjustment is required.
