Form of characters hydraulic pressure draws horse branch form of characters of / to draw the horse ( pulling up the iing turn utensil )
One , the work rule
It is with the hydraulic pressure actuating lever directly ging forward to remove that the hydraulic pressure draws the horse , therefore the driving rod in itself does not act as and turns . The hook pedestal may adapt to once more the whorl directly actes as to go forward to draw back shifts the distance , only the little scope sways about the knob when manipulating , the oil pressure moves before the actuating lever , and the hook one another correspondence is drawed back , is drawed the substance to draw out .
Two , the application limit
It is one kind of fresh means of the idealization that the horse was drawed to the substitution tradition that the hydraulic pressure draws the horse . It is convenient to manipulate , and the use is saved labour , not acceping the limit in space , native draws horse composition tightly , and emploing agilely , weight is light , and the bulk is little , and it is convenient to take along , and is applicable to the plant and the repair arena .

Four , use means together with pays attention to the matter
1 , earlier the laddle when emploing turning on the extremity in trough suit enteres back the oil valve staff , and it is taut soon according to clockwise to go back the oil valve staff .
2 , regulates the hook pedestal up claw Gou gripes the substance drawing .
3 , laddle sticks in to lift inner place the handhole making a return journey to launch the piston actuating lever smoothly to go forward forward , claw relevant drawing back of Gou , and is drawed the substance to draw out .
Therefore 4 , hydraulic pressure is extended the distance when drawing the valid distance of piston actuating lever of horse merely 50mm to employ must not to be more than 50mm ceaseeing when not drawing out , and loosens back the oil valve , and allow the piston actuating lever shrink back , till shiftting well rear second time to duplicate 1 , 2 and 3 moves again to draw out .
5 , on the point of causing the piston actuating lever shrink back , and merely have to turn on the extremity in trough in the way of the laddle shall going back the oil valve staff according to circles the pine against the hands of a clock orientation faintly , the piston actuating lever is living below the spring action by degrees to go back to shrink .
6 , ought to draw distance and load force on the basis of the outside diameter that is drawed the substance before the use , and choose relevant shipping ton hydraulic pressure to draw the horse , and avoids by all means the overload use , and avert the breakdown .
7 , native hydraulic pressure draws that the horse is living - and 5 s ~45 employs among the , and adopts ( GB443-84 ) N15's machine oil ; Is living - 20 s ~-5 employs among the , and adopts ( GB442-64 ) to synthetise bobbin oil .
8 , in the interest of guards against the overload from arousing the machines and tools breakdowns , the hydraulic pressure possess the overload to unload the lotus valve voluntarily inner place the unit , and serveing as when being drawed the substance to overtake the rated load , exceedes the lotus valve be able to unloading the lotus voluntarily , but hydraulic pressure reelecting the greatter shipping ton of use draws the horse .
