When using hydraulic bottle jacks, lift the heavy load and try to lift a part of it first. Carefully check that there is no abnormality in the hydraulic bottle jack and then continue lifting the heavy load. If it is found that the pad is not flat or firm after it is pressed or if the hydraulic bottle jack is tilted, the hydraulic bottle jack must be returned to the pressure, and the cylinder can only be handled in time if it is handled properly.
During the lifting process, an insurance cross-tie should be laid under the hydraulic bottle jack in time with the continuous rise of the weight to prevent the hydraulic bottle jack from tilting or causing the piston to suddenly drop and causing accidents. When decentralizing heavy objects, gradually pull out the sleepers and sleepers. The distance between the weights must not exceed the thickness of a piece of sleeper to prevent accidents!
If the top height of the heavy object needs to exceed the rated height of the hydraulic bottle jack, it is necessary to first cushion the sleeper with the weight lifted by the hydraulic jack, lower the hydraulic bottle jack, raise the bottom of the hydraulic bottle jack, and repeat the lifting until the desired height is raised.
If only one hydraulic bottle jack is used at one end of the jacking weight, the hydraulic bottle jack should be placed on the axis of symmetry of the weight, and the direction of the long jack of the hydraulic bottle jack should be the same as the direction of easy dumping of the heavy load. If two hydraulic bottle jacks are used on one end of the heavy object, the direction of the base should be placed symmetrically on both sides of the symmetrical axis of the weight.
When two or more hydraulic bottle jacks are used for lifting work at the same time, they must be unified in command, coordinated, and lifted.
Hydraulic bottle jacks should be stored in a dry, dust-free place, not suitable for use in workplaces with acids, alkalis, and corrosive gases, but not outdoor sun and rain!
