When we use the elevator elevator, there will always be some unexpected situation, if you judge by feeling is not very serious, you can analyze what is caused, so you can speed up the efficiency of maintenance. So what are the reasons for the fall of the platform during the operation of the elevator and cargo elevator?
The elevator has the functions of lifting, rotating and tilting, etc., controlling the self-locking, interlock, stroke switch, mechanical limit and hydraulic explosion protection measures. The elevator has the following characteristics: the platform structure is compact, stable, can adapt to high-frequency continuous operation; The high stability of lifting height can satisfy the stable lifting of various load platforms. Elevator cargo ladder with external protection wang, overload safety protection hydraulic system, ensure safe operation; Hydraulic elevator cargo elevator roller, ball, rotary table, etc. Can meet the requirements of different operating conditions.
Elevator elevator is widely used in halls, theaters, multi-functional halls, studios, such as elevator equipment cultural and sports venues, can also be assembled according to needs steps, site, multi-stage ladder, elevator elevator composition, can be in different stages of the range, rich stage effect.
In the process of use, the combination of various factors may lead to the decline of the platform. What causes this? How can we prevent and deal with this failure? Let’s analyze it.
Check whether the one-way valve of the hydraulic system is normal, such as the problem of not replacing the new one-way valve. Platform overload, checking that the load is not overloaded, overload will cause the platform to fall, this is a relatively easy problem to ignore.
Lifting platform hydraulic cylinder has leakage, because the cylinder sealing is not good, resulting in hydraulic cylinder leakage, usually sealing ring and other accessories. The tubing is not closed well, and when a leak occurs, the platform pressure drops and the platform surface drops. Check carefully if the tubing is broken.
If the valve is damaged, carefully check that the valve of the elevator is closed tightly and the valve is kept clean. If replaced with a new hydraulic valve. Boarding bridge platform quality problems, we need to remind the customer is not to see the platform price, to see the quality, the word of mouth, choose qualified platform manufacturers.
These are the specific reasons that may lead to the sudden fall of the elevator platform, I believe that we know the formula after reading why.
