1. The table top of the lifting freight elevator is not completely fixed, the rail column and the table top will be shaken, the greater the shaking, the greater the noise. Therefore, when installing the hydraulic freight elevator, it must be fixed firmly, and the long-term shaking will not only generate huge noise. More importantly, the wear on the machine is increased, which is easy to cause mechanical failure.
2. The freight elevator wire rope or chain aging, the hydraulic lifting freight elevator protection device wire rope and chain, if the maintenance is improper or the wear is too large, the product will also have a lot of noise. Therefore, regular inspection and maintenance is to ensure that the rail type hydraulic freight elevator is good. The root cause of the situation.
3. There is a problem with the pump station of the hydraulic lift freight elevator, and the motor will also generate certain noise, but the motor with guaranteed quality is usually very low noise, and some bad merchants often use some motors whose quality is not guaranteed in order to reduce the cost, resulting in hydraulic pressure. The lifting platform is running with constant noise.
4. The cylinder is unqualified, causing excessive noise, because the hydraulic system in the fixed hydraulic freight elevator is the main working system. The cylinder is an important part of the hydraulic system. Once damaged or there is a problem, the elevator will be paralyzed.
