1: hydraulic jack at the lifting operation, to select the appropriate tonnage hydraulic jacks: the carrying capacity can not overload the carrying capacity of hydraulic jacks choose must be greater than 1.2 times the weight of gravity; hydraulic jack minimum height appropriate, in order to facilitate removal, use The minimum height of the hydraulic jacks should headroom weights at the bottom urging adapt the process when landing pad support heavy sleeper, hydraulic jack lifting height greater than the thickness of the sleeper of sleepers and deformation.
2: If you use multiple Pancake Lock Nut jacks lifting the same equipment, the same model should be used hydraulic jacks and hydraulic jacks each rated lifting capacity of the device and not less than the assumed 1.5 times gravity.
3: hydraulic jacks should be wiped clean prior to use, and should check the parts are flexible, without injury, when there is a load should not remove the quick connector, to avoid accidents and damage to components.
4: Before using hydraulic jacks should be placed flat, not tilted to pad the bottom level, to prevent ground sinking or partial load shift tilt or tip over leaving the hydraulic jack, the jack at the bottom of the pad can be tough in the hydraulic pillow surgery or steel to expand pressure area to prevent slip and fall or accident; do not use wood or steel with oil as a liner, when the force to prevent slipping accidents; weight is lifting position must be safe, solid site to preventing damage to the device.
