Because the tonnage of the 8-ton small crane is not very large, once the fault is encountered, the most prone to problems is the slip. Grasping the causes of the slipping hook of the 8-ton small crane and its handling methods can make it have a longer service life and can also increase the safety performance in all aspects.
The reasons for the slipping of the 8-ton small crane are many, mainly in the following aspects:
1. The phenomenon of string oil occurred in the brake storage tank or the spring deceleration capability inside is too weak.
2. A foreign object stuck inside the slot of the small crane brake, causing serious damage to the slot.
3. The balancing valve hole used to keep the internal balance of the 8-ton small crane was seriously blocked, resulting in the loss of the original function of the small crane's balancing valve core, making the internal balance system of the small crane unable to operate normally. As we all know, a very important core component of the 8-ton small crane is the balance valve, which must have good sealing when it is connected to the surrounding devices. Once it is invaded by foreign objects, the components are The closed gap will increase and the resistance between the devices will increase. If you do not perform timely cleaning at this time, the balance function of the 8-ton small crane counterbalance valve will easily fail.
4. The built-in motor of the small crane has self-discharge. Once the self-discharge phenomenon occurs, it means that the starting power to drive the 8 tons of small cranes will become weaker and weaker. In the long run, the small cranes will easily slip out, which will cause accidents in the works.
After clearly understanding the main reason for the slipping of the 8-ton small crane , grasping the following treatment method can quickly restore the original function. First of all, the balance valve of the 8-ton small crane must be re-checked frequently. Once the spring used to pull back the balance valve piston is found to be broken, it must be replaced accordingly. Second, if the valve core of the balance valve has been severely damaged, it is not recommended to perform any maintenance work on it, and the replacement of the new one can reduce the occurrence of slipping on the small crane. The best thing is that when carrying out any operation, it must be carried out in strict accordance with the relevant standards. In dealing with the problem of each adjustment point, it must be taken seriously.
