What are the benefits of reducing the grab weight of double beam crane? The double beam crane includes a fixed base (mobile platform), a pillar fixed to the fixed base with bolts, a rotating arm on the pillar and one end of the electric hoist arm. The rotation axis is set on the lower arm of the rotation axis. The top is equipped with a bearing sleeve, and the rotating shaft is matched with the bearing sleeve. One end of the rotating arm is provided with a heavy object, which is located at the other end of the rod corresponding to the electric hoist. The heavy hammer fixedly connects the tray under the vertical rod of the heavy hammer, and can place the weight of the heavy hammer, and then place the heavy hammer. The end of the block is provided with a groove, and the weight can be stuck in the groove. The bottom of the rotating arm is provided with a T-shaped groove, and the top of the counterweight rod is provided with a sliding plate.

The slider can be clamped in the T-shaped groove on the lower surface of the rotating arm, and the bottom surface of the slider can be slid and fixed in the T-shaped groove. The rotating motor is arranged below the rotating arm, and the rotating motor can drive the rotating arm to rotate. The advantages of using a short jib crane with counterweight: removing the rotating support can effectively improve the effective travel of lifting materials; By increasing or decreasing the weight or sliding weight, the range of short jib crane can be increased to adapt to materials with different weights.. Lifting and transportation.

The operation mode of grab of double box girder crane can be operated in ground operation mode and air operation mode, and the air operation mode can be called air operation. Air operation is the operation mode of the cab.

The ground operation mode can be divided into two operation modes: handle operation and remote control operation. Next, we will introduce the advantages and disadvantages of handle operation, remote control operation and cab operation.

1. Handle operation mode: people walk with cars, rescue people, control driving, and hang objects. Disadvantages: it is more dangerous for people to walk with lifting objects

2. Remote control: lift dangerous objects and cannot follow. Disadvantages: Limited vision.

3. Air Combat: open vision. Disadvantages: the operation of special personnel requires the cooperation of the following personnel.

Because the overall machinery of the double beam crane is relatively simple, we generally use the ground operation mode, and there are more and more remote operation modes. Of course, there are many ways to use air combat, but less than ground combat. After all, ground operation mode is simpler than air operation.
