Are car cranes allowed for construction vessels?

Hello, it is not allowed, the cranes of the construction ship are dedicated, and do not match the land.

There are many types of truck cranes, and their classification methods are also different, mainly including:

1.Classification by lifting capacity: light truck crane (lifting capacity below 5 tons), medium truck crane (lifting capacity of 5-15 tons), heavy truck crane (lifting capacity of 5-50 tons), super heavy truck crane (lifting capacity of more than 50 tons).

Due to the requirements of use, its lifting capacity has a tendency to increase, such as the production of large truck cranes of 50-1200 tons.

2.According to the type of outriggers: frog outriggers, X-shaped outriggers, and H-shaped outriggers.

The frog outrigger span is smaller, and it is only suitable for cranes of smaller tonnage; X-shaped outriggers are prone to slippage and are rarely used; The H-shaped outriggers can achieve a large span and have obvious advantages over the stability of the whole machine, so the hydraulic truck cranes produced in China mostly use H-shaped outriggers.

3.According to the transmission mode of the transmission device, it is divided into three categories: mechanical transmission, electric transmission and hydraulic transmission.

4.According to the range of rotation of the lifting device in the horizontal plane (that is, the rotation range of the turntable): the full slewing truck crane can rotate 360 ° arbitrarily) and the slewing angle of the non-full slewing truck crane is less than 270 °).

According to the structural form of the boom, it is divided into: folding boom, telescopic boom and truss boom truck crane.

Summary. 1.Before the operation, the load, obstacles within the radius, and the foundation should be investigated as clearly as possible to ensure safe operation.

2.Inspect the job site. The working ground should be solid and flat.

Check that the oil in the hydraulic tank is within the specified notch range. 4.Check the tension and wear of the wire rope used for boom telescopic.

5.Check whether the lifting brake is reliable and the fastening of each component and part. Check the firmness of the spreader and buckle.

6.When the hydraulic pump is started, it should run at a low speed and run without load for a few minutes to observe whether there is oil leakage or abnormal phenomena.

What should I pay attention to when the car crane is working on the ship, and can it be lifted on the side.

1.Before the operation, the load, obstacles within the radius, and the foundation should be investigated as clearly as possible to ensure safe operation. 2.

Inspect the job site. The working ground should be solid and flat. In case of soft foundation, or undulating ground, be sure to pad the appropriate wooden blocks, and only start working after confirming that it is safe to change the key.

4.Check the tension and wear of the wire rope used for boom telescopic. 5.

Check whether the lifting brake is reliable and the fastening of each component. Check the firmness of the spreader and buckle. 6.

When the hydraulic pump is started, it should run at a low speed and run without load for a few minutes to observe whether there is oil leakage or abnormal phenomena.

2) Precautions during operation: 1During operation, it is strictly forbidden to stand under the crane arm.

No one shall sit in the cab of the lower car, and heavy objects shall not exceed the top of the cab, nor shall they be lifted in front of the car. 2.Generally, the inclination of the whole machine shall not be greater than, and the handmaker of the chassis car must be locked.

3.If the wind force is greater than 6, the work should be stopped. 4.

When lifting operations, do not pull the outrigger control valve handle. If you need to adjust the legs, you must put the weight of the guessing bucket to the ground. surface, the boom is located in front or behind, and then adjust 5

When heavy objects need to stay in the air for a long time, the drum should be braked, and the driver is not allowed to leave the control room. 6.The operation should be smooth, and Suixiao grinds slowly, and it is strictly forbidden to pull, push, and operate cautiously.

7.Do not use a crane to lift buried or frozen objects.
