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 QYL2D Ⅰ b 2 158 90 60 QYL4D Ⅰ b 4 170 100 60 QYL6D Ⅰ b 6 200 125 70 QYL8D Ⅰ b 8 200 125 60 QYL10D Ⅰ b 10 200 125 70 QYL12.5D Ⅰ b 12.5 215 125 70 QYL16D Ⅰ b 16 230 150 70 QYL20D Ⅰ b 20 240 150 60 QYL20D Ⅱ b 20 240 150 70 QYL20B Ⅰ b 20 200 100 60 QYL32D Ⅰ b 32 260 165 -- QYL32D Ⅰ gb 32 260 145 -- QYL50D Ⅰ gb 50 270 145 -- Production license #: XK06-206-00564 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.
