Reduce the benefits of double girder crane grab weight

What are the benefits of reducing the weight of a double girder grab? The girder crane consists of a fixed base (mobile platform) that is bolted to the struts of the fixed pedestal, a rotating arm on the struts and one end of the electric hoist arm. The rotating shaft is disposed on the lower arm of the rotating shaft. The top is provided with a bearing sleeve, and the rotating shaft is matched with the bearing sleeve. One end of the rotating arm is provided with a weight, and the weight is located at the other end of the rod corresponding to the electric hoist. The heavy hammer securely attaches the tray under the vertical bar of the weight and can place the weight of the weight and then place the weight. The end of the block is provided with a groove, and the weight can be caught in the groove. The bottom of the rotating arm is provided with a T-shaped groove, and the top of the weight bar is provided with a sliding plate.

The slider can be caught in the T-shaped groove on the lower surface of the rotating arm, and can slide in the T-shaped groove and fix the bottom surface of the slider. The rotating electrical machine is disposed below the rotating arm, and the rotating electrical machine is capable of driving the rotating arm to rotate. The advantage of using a jib crane with counterweight: the removal of the swivel bracket can effectively increase the effective stroke of the lifting material; by increasing or decreasing the weight or sliding weight, the range of the jib crane can be increased to accommodate different weights of material. .

The mode of operation of the double box girder crane grab can operate in ground mode and air mode of operation, and the air mode of operation can be referred to as airborne operation. Air operations are the way the cab operates.

The ground operation mode can be divided into two modes of operation: 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 the car, save people, can control driving, and can also hang things. Disadvantages: People use hanging objects to walk more dangerously

2. Remote control: Items that are dangerously dangerous to lift cannot follow. Disadvantages: limited view.

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

Since the overall machinery of the double girder crane is relatively simple, we generally use the ground operation mode, and the remote operation mode is more and more. Of course, there are many ways to use air combat, but less than ground combat. After all, the ground operation mode is simpler than air operation. Which operating mode is used specifically requires the customer to make a selection according to their own conditions
