Single-Acting Lock Nut Low Height Hydraulic Jack

Description of Single-Acting Lock Nut Low Height Hydraulic Jack

The jacking method can avoid high-altitude operations and is convenient for construction, but the jacking technology requires high requirements. A construction method in which the roof structure is assembled or poured on the ground and is gradually lifted to the design level by using jacks and alternately filled columns

Technical Parameter of Single-Acting Lock Nut Low Height Hydraulic Jack

Matters needing attention of Single-Acting Lock Nut Low Height Hydraulic Jack
a) If empty pumping occurs during use, first loosen the oil drain screw on the pump body, turn the pump body vertically, and pump it down a few times, then tighten the oil drain screw to continue to use.
b) When there is a load, do not remove the quick connector to avoid accidents and damage to the machine parts.
c) This machine uses oil as the medium, and the maintenance of the oil and the machine must be done well to avoid blockage or oil leakage, which will affect the use effect.
d) For a new or long-standing hydraulic jack, because there is a lot of air in the cylinder, the piston rod may have a slight sudden jump when starting to use. You can reciprocate the hydraulic jack 2-3 times without load to eliminate air in the cavity. Long-term idle jacks will harden the seals due to the long-term inactivity of the seals, which will affect the service life of the hydraulic jack. Therefore, when the hydraulic jack is not in use, the hydraulic jack should be reciprocated 2-3 times a month without load.

Maintenance matters of Single-Acting Lock Nut Low Height Hydraulic Jack
(1) The bottom of the hydraulic jack should be flat and tough when used. The oil-free wooden board expands the pressure-bearing surface to ensure safety. Iron boards cannot be used instead of wooden boards to prevent sliding.
(2) It is required to be stable when lifting. After lifting the heavy object for a while, check whether there is any abnormality. If there is no abnormality, continue to lift the top. Do not lengthen the handle arbitrarily or operate it excessively.
(3) Not overloaded, super high. When the red line appears on the sleeve, it indicates that the rated height has been reached and the jacking should be stopped.
(4) When several hydraulic jacks are operating at the same time, there must be a special person to command, so that the lifting or lowering can be carried out synchronously. Wooden blocks should be supported between two adjacent hydraulic jacks to ensure intervals to prevent slipping.
(5) When using a hydraulic jack, always pay attention to the sealing part and the pipe joint part, and must ensure its safety and reliability.
(6) Hydraulic jacks are not suitable for places with acid, alkali, or corrosive gas.
