First, the scope of application
Hydraulic jack is a simple lifting tools for building bridges and factories, warehouses, wharves, stack weights and vehicle tires and replacement of the tractor crawler, can also be used to install the hull or keel welding work. Using this product, reduce labor intensity and enhance efficiency.
Second, the performance parameters
Model parameters name from the weight (t) minimum height ≤ (mm) or from the high degree of ≥ (mm) height adjustment ≥ (mm

3, annex
2-50 ton hydraulic jack handle one of the Annex
Fourth, the use of methods and key issues
1. Lifting the handle first before slotting into the back end sets of stem oil and oil to stem the clockwise direction Xuanjin.
2. Insert press handle hand hole from top to bottom press dynamic, rod that is lifting the top of a smooth rise, as the jack in the limited digital device, the top-to a certain height is no longer rising.
3. Spare the Pistons fell, with only handle grooving to the oil terminal will stem the anti-clockwise rotation slightly loose, rod that is slowly declining. If loads can not rotate back to stem the oil too fast, otherwise the general rate of decline in the risk.
4. Objects estimated to be lifting weights, keep in mind the use of overloading.
5. Objects used to determine center of gravity, the choice of Jack focal point, placing a smooth, but must also consider the hard and soft ground level, we must be tenacious wooden mats to prevent a skew even when lifting the dumping.
6. Weights from the top, the weights should be in a suitable position under the pad to the tenacity of wood (or other material) support, just in case Jack failed and dangerous.
7. If several jack and use, up from the rate should keep pace, and each of the load jack should also be balanced, otherwise would have dumped dangerous.
8. Jack in this -5 ℃ ~ +45 ℃ in use, use of (GB443-91) N15 mechanical oil in -5 ℃ ~ -20 ℃ to use, use of (GB442-64) of the spindle oil. Jack must maintain sufficient by the filters clean the oil or else the work will be less than the lifting rated highly.
9. Should avoid the use of a sharp shock.
