About this product
1. Flat design works for operations in narrow space.
2. The base screw holds facilitates fixation.
3. It dose not need extra cushion block with irrigation tank type axis surface.
4. Pistonc with hard chromium processed is wear and corrosion resistance.
5. The strong spring speeds the main axis retraction.
6. The nut protects the spindle from over-extending.
7. All kinds of models have the 3/8" NPT quick connector.
This hydraulic cylinder is often used in power, chemical, steel, bridge, machinery and other industries, not for the CAR.
(1).The utility model has the advantages of smaller size and greater working capacity, especially in the narrow space position, and has the functions of portability, flexibility, big jacking force, etc.
(2).When the hydraulic jack is used, the bottom should be flat and tough. Oil free wood panels to expand the pressure surface, to ensure safety. Iron can not be used instead of planks to prevent sliding.
(3).When lifting requires a smooth, heavy load slightly to check whether there is any abnormal situation, if there is no abnormal circumstances to continue jacking. Do not arbitrarily lengthen handle or excessive operation.
(4).When several hydraulic jacks work at the same time, they should be directed by someone to make the lifting or falling simultaneously. Two adjacent hydraulic jacks shall be supported with wooden blocks to ensure that the gap is secured against sliding.
(5).When using hydraulic jack, always pay attention to the sealing part and pipe joint part, and must ensure its safety and reliability.
(6).Hydraulic jacks are not suitable for sites where acids, alkalis, or corrosive gases are applied.
