How To Ensure The Safe Use Of 5 Ton Jib Cranes

 

Jib crane is a light and small lifting equipment. As a kind of mechanical equipment, its operation is very risky, so it is very important to do a good job of protection.

 

Today we mainly introduce the safe operation procedures of 5 ton jib cranes.

 

1. The equipment personnel of the jib crane must hold relevant certificates for replacement parts before they can work.

 

2. It is necessary to wear a safety helmet, suitable clothes and safety belt during operation.

 

3. Professional lifting equipment is required for hoisting, and a suitable crane should be selected according to the load of the jib crane itself.

 

4. According to the "Safety Operation Regulations for Cantilever Cranes", operators must work under the hanging objects to prevent them from falling and endangering personal safety.

 

5. The steel wire ropes used for jib cranes must not be broken, twisted or broken. The wire rope must be selected according to its weight to ensure its normal and safe use.

 

6. Cantilever crane equipment is a good safety protection facility. Please fasten your seat belt before using the device. Ladders should be free from cracks and damage.

 

7. Ladders must be firmly fixed below before use. When the ladder is not high enough, it is forbidden to place other items under the ladder.

 

 

The cantilever crane is a light duty crane composed of a column, a reversing arm, a reversing drive device and an electric hoist.

 

It has the advantages of light weight, large span, large lifting capacity, economy and durability. High mechanical efficiency, convenient equipment, operation and maintenance, and low cost.

 

The cantilever column is made of round pipe, the bottom plate and the rotating shaft are welded at both ends, and the upper part is equipped with a waist ring track. The bottom plate and the concrete bottom plate are connected and fixed by chemical bolts to ensure the stability of the cantilever crane. A through hole is provided on the rotating shaft to complete the concealed installation of the cable from the column. A 360° collector can be installed on the rotating shaft to complete the n×360° rotation of the rotating arm.

 

The cantilever crane uses a circular track to rotate. There are multiple through holes on the track, which are used for equipment limit stops, which can complete the angle constraint of 0-360 degrees. The structure of the vertical jib crane is composed of I-beam and I-beam, which can be used for the equipment and operation of various chain cranes.

 

There are movable pulleys at both ends of the cantilever crane to ensure that the crane can work within a specific stroke.

 

The bracket of jib crane is welded by rectangular tube and steel plate to support the rotating arm. Triangular support, superior mechanical structure, light weight and high safety. Two swivel wheel devices are under the bracket. The wheel tread cooperates with the track of the waist ring, and the structure is stable. One of them is the driving wheel, which is driven by a light worm gear motor to complete the electric rotation of the jib crane.

 

The cantilever crane reversing equipment adopts a round pipe as the shell, and self-aligning roller bearings are installed inside to realize the free rotation of the arm. Due to the performance of the spherical roller bearing, the jib crane can be safely used even if the concentricity of the waist ring and the column is slightly different. A C-shaped track can be installed on the swing arm of the cantilever crane, which is used to install the power cable of the electric hoist.
