How to Select a hydraulic system when you to buy hydraulic puller

When choosing the proper system for a specific application, several points must be considered:

Puller Reach

Puller reach is the available distance between the pulling surface of the jaw and the jaw head

of the puller. This distance varies and decreases as jaws are opened. When choosing a puller,

make certain the reach is sufficient to attach the puller.

Puller Spread

Puller spread is twice the distance from the ram to the pulling surface of the jaw. In choosing

the proper puller make certain the puller has a large enough spread to attach to the object

being removed.

Tonnage

Tonnage is the maximum pulling force that can be safely exerted by the puller. Tonnage may

be estimated by looking at the torque curves. The maximum force exerted in tons should

be seven to ten times the diameter of the shaft in inches. IE: a 1.5 inch diameter shaft

would generally require a 15-ton hydraulic puller.

Pump

The pump must have the adequate oil output and reservoir capacity to power the cylinder.
