Double acting hollow hydraulic jack for sale
Electric Double acting hollow hydraulic jack has a strong jacking lift, so that some heavy objects can be it is very good lifting lifting, very convenient to carry, is our daily work inspection, maintenance of the important lifting tools. The synchronous jacking overcomes the problem that the lifting weight of a single jack should tilt, which leads to the damage and danger of the lifting weight.
Should be used when using multiple synchronous diverter valve, and to the top of each should be balanced lifting loads and keep the speed of lifting and falling synchronous intelligent tensioning jack has several such as mechanical jacks and hydraulic jack, principle is different from the principle of wave pressure transmission is based on the basic principle is the PASCAL's principle, that is, in all parts of the liquid pressure is consistent, so, in a balanced system, the smaller piston top pressure is small, and the big pressure on the piston is bigger, it can keep the liquid stationary.
Double acting hydraulic jack, hydraulic piston return; piston rod plating 40Cr metal layer Increase surface brightness and hardness Prevent air corrosion; the piston and the guide ring are made of copper, which is more wear resistant. The special guide ring design can withstand an eccentric load of up to 5% of the rated load capacity of the jack. It is equipped with a dust-proof ring to prevent dust from entering the cylinder. All models include quick connectors and dust caps. Up to 13 seals inside the cylinder to ensure sealing performance and extend service life.
We will recommend different hydraulic jack for customers according tonnage, stroke and application:
1. Require multiple jacks to lift at the same time or multi-point synchronous jacking, please choose electric synchronous hydraulic jack.
2. For objects that require heavy lifting, please choose electro-hydraulic jack.
3. If you need to replace the bridge support, please choose the thin synchronous hydraulic jack.
4. If you need long-term load work, please choose self-locking hydraulic jack.
5. Limited operating space should choose ultra-thin hydraulic jack with low body height.
6. When using hydraulic cylinder, first try to lift a part of the weight first, carefully check the hydraulic jacks after abnormalities, and then continue to lift the heavy objects. If the mat is found to be uneven after being pressed, not strong or the hydraulic jack is skewed. When it is necessary, the hydraulic jack must be depressurized and returned to the road, and the front can be disposed of in time to operate again.
