Precautions and safety knowledge for crane operation

The crane is a relatively common type of construction machinery. Generally, cranes are powered by hydraulic pressure and are equipped with various hydraulic devices. If the driver fails to abide by the operation and maintenance rules, it will not only cause the crane to lose the opportunity to fully exert its performance, but also shorten the service life of the components. Colleagues, drivers should also pay attention to safety knowledge when using it to avoid causing unnecessary harm to themselves and others.

Precautions for Crane operation

Before starting the operation, it should be determined through the oil tank level window whether the hydraulic oil is filled up as required. If it is below the specified mark, it must be replenished. When refueling, it is essential to fill through the fuel filter screen and be extremely careful not to mix in oil of different grades or impurities such as water.

The filter element of the oil filter should be inspected after 250 hours of operation. If necessary, it should be cleaned or replaced.

3. The hydraulic oil tank should be drained of water and impurities from the bottom oil drain port once every half a month, and all the hydraulic oil should be replaced every year (or after 2000 hours of operation). If the oil has not deteriorated, the oil change cycle can be appropriately extended. When cranes are operating in particularly harsh environments, the oil replacement cycle should be shortened accordingly.

4. All kinds of valves in the hydraulic system have been fully tested before leaving the factory and the pressure and flow have been adjusted properly. Do not touch them casually.

5. All kinds of machine parts, especially the devices of the hydraulic system, must be kept away from dirt. After doing the work, be sure to clean up all the dust and oil stains thoroughly.

Safety knowledge for crane operation

The structure and performance of each component of the crane being operated; Crane operating procedures and relevant laws and regulations; Safety operation requirements; The structural principle and performance of safety protection devices; Basic knowledge of electric motors and electrical systems; Command signal; Basic knowledge of maintenance and repair.

Safety requirements for crane drivers

The command signals should be clear and comply with the regulations. When hoisting, the Angle between the hoisting ropes should be less than 100 degrees to avoid excessive force on the ropes. The corners and edges through which the hanging rope passes should be padded. When directing an object to flip, ensure that its center of gravity changes smoothly and do not make any movements beyond the intended direction. When entering the area below the suspended heavy object, contact the driver first and set up the supporting device. When multiple people are tied up, one person should be responsible for giving instructions.
