Cautions for Use of HEKVEK Double-acting Hydraulic Jack
Before using HEKVEK double-acting hydraulic jack, it is necessary to check whether all parts are normal. When using it, we should strictly follow the key parameters in HEKVEK instructions and avoid all means by high overload. Otherwise, when the lifting height or lifting tonnage of the mechanism is larger than the top of the cylinder, important lubricants will be produced.
If the manual volume of HEKVEK hydraulic pump body is not urgent, the first step to join the pump must be to fully filter N33.
The center of gravity should choose the proper and accurate pick-up point from the bottom to the cushion level, and study the premise of hard to the ground at the same time. It is necessary to liner solid wood and keep it stable so as to avoid self-weight sinking or skewing. If jacks are blocked, it is necessary to maintain stable weight and prevent jacks from servicing.
If HEKVEK jacks need to be lifted at the same time, in addition to accurate placement, more branch valves should be used, and the load of each jack should be balanced, focusing on maintaining synchronous lifting rate. Some studies have also been carried out to prevent deflection and danger of lifting objects due to the uneven weight of the land.
When the manual pump is applied to the quick joint and docking, then choose the correct address, tighten the pump with the oil drain screw, it can work. You need to make the piston rod, twist the manual pump a little, the hand wheel counterclockwise and the unloading cylinder, the piston rod will gradually fall off. Otherwise, the fall will also cause risks.
This is a spring reset structure, which can be quickly removed after hoisting, but not practical. The connection hose is pulled. Because the lifting stroke is small, users should carefully use it not to exceed the rated stroke in order to avoid damage.
