What Is a Pulley Puller?

The integral puller uses the hydraulic starting rod to move forward directly, so the push rod itself is not used for transmission, and the claw base can be adjusted forward and backward with the thread. It is easy to operate, as long as the handle is swung back and forth slightly.

Hydraulic puller is an ideal new tool to replace traditional puller. , Flexible use, light weight, small size, easy to carry, labor-saving, non-slip, not restricted by the site, direction (0-360 °), position (2 claws, 3 claws), widely used in gears, bearings, pulleys, etc. .

Hydraulic puller is an ideal new tool to replace traditional puller. Easy to operate, this Rama has a compact structure, flexible use, light weight, small size, and easy to carry. It is labor-saving, non-slip, not restricted by the site, direction (0-360 °), position (2 claws, 3 claws), and is widely used. For disassembly of various discs, flanges, gears, bearings, pulleys, etc.

1 When using, tighten the oil return valve stem clockwise.

2. Adjust the claw base to the claw hook to grasp the object being pulled.

3. Insert the handle into the lifter's hole to tilt the piston start lever forward and back smoothly, and the claw hook will retract accordingly and pull out the pulled object.

4. The effective distance of the piston starting rod of the hydraulic puller is only 50mm, so the extension distance should not be greater than 50mm when used. Stop when it is not pulled out, loosen the oil return valve, and let the piston starting rod retract. Repeat steps 1, 2, and 3 until it is pulled out.

5. To retract the piston starting rod, just loosen the oil return valve rod counterclockwise with the slotted end of the handle, and the piston starting rod gradually retracts under the action of the spring.

6. Before use, you should choose the hydraulic puller of corresponding tonnage according to the outer diameter, pull distance and load of the object being pulled. Avoid overloading to avoid damage.

7. The hydraulic puller is used at -5 ~ 45 , using (GB443-84) N15 mechanical oil; used at -20 ~ -5 , using (GB442-64) synthetic spindle oil.

8. In order to prevent damage caused by overload, the hydraulic device is equipped with an overload automatic unloading valve. When the object being pulled exceeds the rated load, the overload valve will automatically unload and use a larger tonnage hydraulic puller instead.

9. This machine uses oil as the medium. It is necessary to do the maintenance work of the oil and the machine to avoid blockage or oil leakage, which will affect the use effect.

10. For new or long-time hydraulic pullers, because there is more air in the cylinder, the piston rod may have a slight jump phenomenon when it is used. The hydraulic pullers can be reciprocated 2-3 times without load to eliminate Air in the cavity. The puller that has been idle for a long time will cause the seal to harden due to the long-term non-operation of the seal, which will affect the service life of the puller. Therefore, when the puller is not in use, the puller will be reciprocated 2-3 times a month without load.
