Range of application
Hydraulic Rama Rama is an alternative to the traditional idealized
new tools. Easy to operate, effort, subject to site constraints,
the Rama compact, flexible, light weight, small size, easy to
carry, suitable for factories, repair place.
working principle
Hydraulic rama is hydraulic starting lever directly move forward,
so the push rod itself does not make the turn.Hook claw seat can be
made directly with the thread pitch forward and back, as long as
the operation after a slight swing handle, hydraulic actuating
lever forward, corresponding hook claw back, the object is pulled
out.
Using method & Note
1、using the slotted end of the handle when the first set into the
oil return valve stem and valve stem oil return tighten clockwise.
2、the hook claw adjust to hold on the pulling objects.
3、he handle into the lift hand hole piston actuating lever forward
tilt back and forth smoothly forward, claw back accordingly, an
object to be pulled out.
4、starting piston rod of hydraulic Rama effective distance is only
50mm, so the use of extended distance not greater than 50mm, pulled
out when there is no stopping, release the oil return valve, so
that the piston rod is retracted starting to go after a good tune
second repeat steps 1,2,3 times out so far.
5、purports to retract the piston rod starts to go, simply use the
slotted end of the oil return handle counterclockwise slightly
unscrew the valve stem, the piston rod in the spring under the
starter gradually retraction.
6、prior to use should be based on the outside diameter of the
object is pulled, pull away and load force, select the appropriate
tonnage hydraulic Rama, avoid overloading, to avoid damage.
7、hydraulic Rama use temp at -5 ℃ ~ 45 ℃ , the use of (GB443-84)
N15 machine oil; at -20 ℃ ~ -5 ℃, the use of (GB442-64) synthetic
spindle oil.
8、in order to prevent equipment damage caused by overloading,
overloading hydraulic unit equipped with automatic unloading valve,
when the object is pulled over the rated load, overload valve will
automatically unloading and instead use a larger tonnage hydraulic
Rama.
