Since the lock style hoisting jack

One , the use
Since the lock style hoisting jack requires chiefly to be used the elder time support heavy object space , and that it may be living yet may back the heavy object when take-offing the oil pressure , but also safe and reliable . Usable to under water , the load is goed back to shrink the list action , and the causing load of nut since the lock is securer , particularly being living in the large project , and being easy operation control and the hydraulic pressure hoisting jack , the design possess secure guarantor to be getting near the unit , and the integral is unloaded the pressure valve and is guarded against the load factor , and in order to safeguard the hoisting jack is in order to benefit the secure operation . What adopts is , and high-handed gum tube and whorl join the joint to that the unit joint , and it is prompt to have the use , and overcomes speedily traditional connector to leak the installation that the oil defect is chiefly used much kinds of professions such as the electric power , structure and machine manufactures , mining area , railroad bridge and shipbuildings and so on to have fixed that the peak disassembles the task .

Two , the use means
1 , in case when pump part of the body oil amount defect , talent requireing to accede to to the pump work oil ( 10#'s machine oil ) earlier to do .
2 , appraise weight , and avoided by all means the overload use .
3 , has fixd the heavy object core , choose the hoisting jack force , have to consider whether the shy stiff degree of the earth is paded with tough and tensile timber moreover , so as not to when geing up severely come into being to topple over peril .
4 , the hoisting jack ascends queen by the heavy object peak , ought to without delay employ tough and tensile timber by the heavy object support prison , and ban emploing the hoisting jack as the support matter , so as not to the burden is not eqilibrium , comes into being to topple over peril .
5 , fast connector together with peak that stirs the pump by the hand earlier when emploing docks , afterwards chooses the good place , it is taut soon by the oil the placeeing screw on the oil pump , in immediate future may do . Shall place the oil screw circles the pine , and the oil vat unloads the lotus .
Please 6 , the electric pump is consulted and follow the power-driven use manual .

Three , the fundamental parameter

Four , pay attention to the matter
A ) the appearance is strike as having ariseed to empty when emploing , yet looseing the oil the placeeing screw in the pump part of the body earlier , and gets up the pump part of the body uprightness that the backing empties and makes a call to some times down , afterwards tightly places the oil screw soon , and in immediate future may go on the use .
B ) is living when possesing loading , avoids by all means by speedily joining to unload second , and reaching to injure the works so as not to happenning the mishap .
C ) native engine is in the way of oil act as the medium , have to make good oil reaching machines and tools keeping in good repair work , so as not to being choked with silt either leaking oil , effect employd in the effect .
D ) fresh either places the long oil pressure hoisting jack , as a result of the oil vat memory possess more air , when startting emploing , the piston rod has probably ariseed little projecting the leaping appearance , yet by the oil pressure hoisting jack zero load moves back and forth to move 2-3's degree , in order to remove the air inner place the cavity . The hoisting jack over a long period of time leave unused since sealing airtight piece does not over a long period of time do to create dense the hardening , thereby the effect oil pressure hoisting jack service life , per month will move back and forth to move the oil pressure hoisting jack zero load 2-3's degree therefore the oil pressure hoisting jack is when being living the disuse .
