Truck crane is a common lifting equipment, widely used in construction sites, logistics warehousing and other fields. The correct use of crane can not only improve work efficiency, but also ensure the safety of the construction process. This article will explain in detail how to properly use the crane, including operating procedures and safety precautions.

Operation procedure

1. Check the status of the crane in advance

Before using the crane, a comprehensive inspection of the equipment is essential. Check key components such as boom, wire rope and electrical system to ensure that all parts are intact. At the same time, confirm the adequacy of hydraulic oil, fuel and other liquids.

2. Do site preparation work

Before using the crane, ensure the flatness and load capacity of the work site. Clear the obstacles on site and ensure that the crane has enough operating space. For different job sites, some special preparation work may be required, such as setting up signs, isolation strips, etc.

3. Determine the weight and lifting point of the objects

Before the lifting operation, accurately measure and confirm the weight of the lifting object, and determine the location of the lifting point. According to the size, shape and center of gravity position of the suspended object, the reasonable selection of the lifting point, to ensure that the suspended object in the lifting process of stable suspension.

4. Control the position of the boom and hook

After starting the crane, the position of the boom and hook is controlled by the control system. According to the height and hanging position of the lifting object, adjust the expansion and rotation of the lifting arm, so that the lifting hook can accurately reach the predetermined position of the lifting object.

5. Lifting and moving objects

After lifting the crane, move the crane slowly to ensure that the crane remains stable during the suspension process. Through coordinated operation, the movement of the crane and the precise positioning of the lifting object are realized. Avoid sudden stop and start, in case of shaking or danger.

6. Finishing the lifting task

After completing the lifting task, slowly place the lifting object to the designated position. Then, the lifting arm is recovered and the hook is closed to stop the operation of the crane. Conduct a full equipment inspection to ensure that the crane is in safe condition.

Safety precautions

1. Check the device stability

Before starting the crane, ensure the stability of the equipment. Check that the leg and leg screws are secure, and that the equipment is parked on a solid, flat surface.

2. Keep communication open

In the operation of the crane, the operator and the command personnel need to maintain smooth communication. Use wireless walkie-talkies or other communication devices to ensure the accurate transmission of operational instructions.

3. Prevent power line contact

When carrying out lifting operations, attention should be paid to preventing the risk of contact between the boom and the hook and the power line. Keep enough safe distance to keep the hook away from the power line.

4. Prevent risks and collapses

During lifting operations, be alert to risks and the possibility of building collapse. Maintain a safe distance between the equipment and the building to ensure that the work site is ventilated.

5. Regular maintenance and overhaul

In order to ensure the normal operation and safety of the crane, regular maintenance and overhaul should be carried out. Check the hydraulic system, electrical system, hook, boom and other key components, timely find and solve problems.

6. Strictly follow the operating procedures

The operator must strictly abide by the operating procedures of the crane and shall not violate the operating instructions of the equipment without authorization. Before operation, ensure that the operator has received relevant training and assessment.

Through proper operation and following safety precautions, the safety and efficiency of the use of the crane can be ensured. In actual use, the operator needs to have professional operation skills and maintain a high degree of vigilance to prevent potential dangers.
