When a 500kg manual platform trolley experiences a downward movement during the transportation of goods, our first reaction is whether the brake is broken or there is a problem with the hydraulic cylinder. Yes, when encountering this situation, we should first think of this issue. Below, we will summarize why this phenomenon occurs.

1: Is it due to overloading? Each manual platform truck has a fixed weight in kilograms, and if it exceeds this weight, the pressure will be too high, causing this problem.

2: Is it a problem caused by the delivery of parts? The equipment has been traveling on bumpy roads for a long time, resulting in loose parts.

3: After the aging of the hydraulic gasket, the sealing is not tight enough, resulting in this phenomenon. Check if it is a problem with the sealing ring.
