If multiple 200 ton high efficiency single acting high tonnage lock nut hydraulic jack are used to lift the same equipment, the same type of hydraulic jacks should be used, and the sum of the additional lifting weight of each hydraulic jack should not be less than 1.5 times the gravity of the equipment. 200 ton high efficiency single acting high tonnage lock nut hydraulic jack should be wiped clean before use, and should check whether the components can be active, whether there is any damage, avoid loading the quick joints when there is load, to prevent the occurrence of faults and damaged parts.

New or long-term single-acting hollow hydraulic jacks, because there is more air in the cylinder, when the piston is used, the piston rod may show a slight jump phenomenon. The single acting hollow hydraulic jacks can be reciprocated 2-3 times without load to eliminate The air inside the cavity. Long-term idle jacks, because the seals do not work for a long time, causing the seals to harden, thus affecting the service life of the hydraulic jacks. Therefore, when the hydraulic jacks are not in use, the hydraulic jacks should be reciprocated 2-3 times per month.
