Multi-purpose hydraulic tool |
摘要 |
A multi-purpose hydraulic tool of the open center and closed center type is provided with an OC/CC knob mounted on the trigger activated spool. The spool has a knob which can be turned to easily move between OC and CC operating conditions, without the use of additional tools. A check spool assembly works in conjunction with spool assembly in the open-center condition to provide for release of oil at the end of the return stroke. Adapters are provided so that crimping heads can be easily interchanged.
