What safety matters need to be paid attention to when using fixed cranes?

Wuxi Xishan Port Hoisting Machinery Co., Ltd. shares what safety matters need to be paid attention to when using fixed cranes?

Fixed crane is a common lifting equipment, often used in construction sites, docks, warehouses and other places to lift and carry heavy objects. Safety is very important when using a fixed crane. Here are some safety things to pay attention to when using a fixed crane.

Check the equipment: Before using the fixed crane, you must carefully check the condition of each component of the equipment and the spreader to ensure that the equipment is in good condition, not damaged or loose, and has the necessary operating manuals, certificates, maintenance records, etc. If any damage or problem is found with the equipment, it should be reported and repaired promptly.

Determine the lifting range: Before use, it is necessary to clarify the weight, size and other special requirements of the lifting object, and compare it with the rated lifting capacity of the crane to ensure that the lifting object meets the safe use range of the crane.

Foundation and support conditions: The safe use of fixed cranes is closely related to infrastructure. It is necessary to ensure that the foundation of the equipment is solid and the ground is solid and flat. If you are using a mobile crane, you also need to ensure that the fuselage has stable support, such as using skids, bricks, etc.

Operators must be qualified: Personnel operating cranes must undergo professional training and assessment, and hold corresponding operating certificates. Operators need to be familiar with the structure, performance, operating procedures and corresponding safety regulations of the crane.

Ventilation and lighting: The workplace should have good ventilation and lighting conditions to ensure that operators can clearly see the working environment and lifting objects, and improve the safety of operations.

Overloading is prohibited: The rated lifting capacity of the crane is limited, and overloading operations are strictly prohibited. During the lifting process, attention should be paid to monitoring the weight of the lifting object to ensure that it does not exceed the rated lifting capacity of the crane, and calculation and confirmation should be made before hoisting the lifting object.

Safety protection devices: Complete safety protection devices should be installed on fixed cranes, such as limiters, lifting height limiters, anti-collision devices, anti-skid devices, etc. These safety devices can provide alarms, cut off power and other protective measures to ensure the safety of operators and equipment.

Prevent falling: During the lifting process, pay attention to prevent the lifting object from slipping or falling, and ensure that the lifting object uses appropriate fixing devices, such as hooks, ropes, etc.

Avoid collisions: During operation, avoid collisions between the lifting object and surrounding equipment, buildings, personnel, etc., and maintain a sufficient safety distance.

Personnel are prohibited from standing under lifting objects: During the lifting process, personnel are strictly prohibited from standing under lifting objects to prevent injuries caused by falling objects.

Properly equipped with spreaders: The crane should be equipped with appropriate spreaders and safety devices to ensure the stability and safety of the hoisted items. The selection of the spreader should meet the characteristics and needs of the lifting object. When using it, check the status of the spreader and whether the fixing device is firm.

Regular maintenance: Stationary cranes require regular maintenance, including cleaning, lubrication, tightening bolts, and inspection of wires and cables, etc. Regular maintenance can ensure the normal operation and service life of the crane, and identify and solve potential safety problems.

Wind conditions: When using a stationary crane, you need to pay attention to weather conditions, especially wind conditions. When the wind force is greater than the safe operating limit of the crane, use should be suspended to avoid safety accidents such as overturning of the lifted object and instability of the crane.

On-duty inspection and communication: During the use of the crane, equipment inspections should be carried out regularly to detect and deal with equipment problems in a timely manner. At the same time, it is necessary to maintain timely communication with relevant personnel to ensure work coordination and safety.

In short, when using a fixed crane, you should strictly follow the operating regulations and standards, and master the corresponding safety knowledge and skills. Proper safe use of cranes can effectively avoid lifting accidents and ensure safe production in the workplace.
