Installation method of group crane electric hoist basket
As an advanced auxiliary construction technology, electric gondola has been accepted by more and more construction companies and has been applied in construction projects. The electric hoist has a compact structure, and the electric hoist whose motor axis is perpendicular to the axis of the drum adopts a worm gear transmission device. Its disadvantages are: large length dimension, large width dimension, rough structure, low mechanical efficiency, and difficult processing. The hydraulic system is dual-controlled, and the pressure can be precisely controlled by the overflow regulating valve and the magnetic contact pressure gauge. The electrical control department adopts low-voltage control, which increases the safety of the control system. Especially in recent years, with the rapid development of my country's economy, more and more high-rise and super high-rise buildings have been built one after another, making the electric gondola rapidly popularized. The electric hoist has a compact structure, and the electric hoist whose motor axis is perpendicular to the axis of the drum adopts a worm gear transmission device.

The hydraulic system is dual-controlled, and the pressure can be precisely controlled by the overflow regulating valve and the magnetic contact pressure gauge. The electrical control department adopts low-voltage control, which increases the safety of the control system. The detailed installation process of the electric gondola: First, the installation of the gondola should check whether the safety lock is flexible. When pulling the pulley, it should be light and not blocked.
Second, check the lifting and tilting mechanism, press the button to make the lifting and tilting mechanism idling, and check whether the operation is normal, there is no noise and blocking phenomenon. The safety rope enters the safety lock and moves the counterweight upward. Start the tilting mechanism, the wire rope enters the tilting mechanism, and the rope end should automatically exit the rope exit.
Before checking the gondola again, you must read the product manual and train the operators to understand the working principle of the equipment, precautions and safe operation procedures.
Finally, the weight of heavy iron must be sufficient. The torque at the counterweight end should be 3 times the torque at the basket end (torque arm = moment). The joint should be firm and reliable. The distance between the sling and the safety lock should be adjusted after assembly. By moving the safety lock, the hanging basket tilts 6-8 degrees, and the safety lock can lock the safety rope until the safety rope reaches the end.
