Operation method
1. Oil valve stem screw tighten on deasil first
when using.
2. Adjust hook claw to claw hook hold the
objects.
3. Raise handle hand hole to lift filling
pump upper and lower, corresponding to go backwards, claw hook have back
and forth inside to insert, the object is pulled out
to draw the quilt.
4. Cylinder rod form journey once is 60mm
for the hydraulic pressure of drawing
the horse, so can’t be greater than 60mm
while stretching the distance while
using, when the work was not pulled out
stop in time, lossen the oil valve stem,
let the cylinder rod contract back, the
second time repeated 1, 2, 3 step after setting.
5. If want to make cylinder rod contact
back, it only need go back to lossen the right
valve stem in counterclockwise direction
little to little, the cylinder rod has gone
back to contract gradually under the
function of the spring.
6. Should according to external diameter
of the object, draw distance and load
strenght, choose corresponding hydraulic
pressure of tonnage draw horses before
using, must guard against overloading to
use, avoid damaging.
7. Last horse hydraulic pressure using
in-5 degrees Centigrades-in 45 degrees
Centigrades, adopt(CB443-84) by N-15
machinery oil; in -20degrees Centigrade
-in -5 degrees Centigrade, adopt(CB442-64)
formate the spindle oil.
8. In order to prevent to cause machines
damage for overload, hydraulics setting
set up overload to unload valve
automatically, work piece will don’t retreat and
enter, should reelect with large hydraulic
pressure of tonnage draw horses at
this moment.
