Hydraulic tools, systems for tools, and methods of use or control of same

Abstract

A hydraulic tool that executes a sequence of operations includes: a motor; a pump; hydraulic fluid driven by the pump; a chamber in fluid communication with the hydraulic fluid; a ram movably positioned at least partially in the chamber according to the hydraulic fluid and pressure thereof; a primary trigger configured to cause, upon actuation thereof, activation of the motor thereby causing: the pump to move hydraulic fluid from the reservoir into the ram chamber, extending the ram; a control system; and at least one sensor in communication the control system. When the primary trigger is user actuated and the ram is fully extended or the tool is clamped around a work piece, the pump continues to pump fluid, under at least partial control by the control system, until a threshold condition is determined by the at least one control system using the at least one sensor.
