Lifting Taiwan natural decline
|
One-way valve drain
|
Check valve in the valve group. If it is found that the single valve sealing surface dirt cleaning, check valve.
|
|
Drop valve closed lax
|
Check whether the decline in electricity, such as electricity is ruled out by the fall of the valve itself or the replacement valve failure. Drop valve spool valve must be kept clean, flexible and mobile.
|
|
|
Oil pipe or valve connection parts
|
Tighten or replace the cylinder seal
|
|
|
Lifting platform does not drop
