We know that the outriggers of small cranes are very important to the work of cranes, but how to operate them in the work is normal?

The role of the outrigger of the small crane is to ensure that the crane can carry out the lifting operation smoothly when lifting, and the crane will not roll over due to imbalance. Therefore, it is very important to avoid the failure of the crane's outrigger. If the outrigger fails, the crane will easily roll over.

However, how can we know that the outrigger has failed? below Huai'an Crane Rental Company Let's introduce the manifestations of crane leg failure:

1. When the crane is working, the chassis has obvious subsidence, which may be caused by the imbalance of the crane;

2. If the outrigger seat of the crane falls automatically, the outrigger also fails;

3. If the outrigger moves too slowly, it is usually because the outrigger structure is stuck by foreign matters. The fault can be eliminated by checking the outrigger structure;

4. After the outrigger switch is turned on, the outrigger has no reaction, and the outrigger structure of the crane should also be checked.

If the outrigger of the crane has the above phenomenon, it means that the outrigger of the crane has a fault, and it should be checked and repaired in time!

1. When the crane is working, four outriggers are used to support the load of the whole vehicle and working device, and the outriggers are supported by the outrigger oil cylinder to start the internal combustion engine. First, operate at low speed for a period of time. After the water temperature and oil temperature are normal, connect the power takeoff of the hydraulic pump and drive the hydraulic pump to start working. Check that there is no leakage in the hydraulic system and the oil pressure is normal, and then start outrigger operation on the right side of the crane.

2. Inspection of operation site. The crane shall not be parked on the seepage well, air raid shelter, soft and inclined ground, retaining wall and high voltage line for lifting operation. If it is necessary to operate on such a site, safety measures shall be taken. If the crane operation site is uneven, steel plates or sleepers of appropriate thickness and size shall be used for filling and padding to ensure a solid foundation under the foot plate.

3. Observe whether there are obstacles before extending outriggers.

4. The horizontal outrigger pin must be pulled out before outrigger installation. When the outrigger is not set, the boom shall not be turned to the side or rear.

5. Before outrigger installation, put the lower gearbox in neutral position, engage the parking brake, and use the stabilizer to engage the axle.
