Portable hydraulic crimping tool

A hydraulic tool comprising:

• a frame having an anvil adapter and a substantially flat guide surface;
• and
• a movable adapter movably mounted to the frame to move relative to the frame along an axis of translation, the movable adapter being adapted for working a workpiece in cooperation with the anvil adapter and having a substantially flat support surface seated against the guide surface;
• wherein the support surface and guide surface interface to prevent rotation of the movable adapter about the axis of translation relative to the frame, and wherein the frame includes a bearing surface adapted for maintaining alignment of the movable adapter with the axis of translation, the bearing surface being disposed in the frame so that the movable adapter does not contact the bearing surface.

A hydraulic tool comprising:

• a frame with a hydraulic fluid reservoir connected to the frame;
• a ram assembly movably mounted to the frame, the ram assembly comprising an outer ram and an inner ram housed in the outer ram, both inner and outer rams being movable relative to the frame;
• and
• a hydraulic fluid conduit system disposed in the frame between the ram assembly and the fluid reservoir;
• wherein the outer ram is adapted to be advanced relative to the frame by the inner ram and by hydraulic fluid pressure against the outer ram, the outer ram being advanced by the inner ram pressing against the outer ram when hydraulic fluid pressure in the conduit system is below a predetermined pressure, and the outer ram being advanced by hydraulic fluid pressure against the outer ram when hydraulic fluid pressure in the conduit system is above the predetermined pressure.

A hydraulic tool comprising:

• a frame with a hydraulic fluid reservoir connected to the frame;
• a hydraulic fluid conduit system extending through the frame from the reservoir;
• a ram movably mounted to the frame, the ram being adapted to be moved relative to the frame by hydraulic fluid from the conduit system;
• and
• a rapid advance ram actuator movably mounted to the frame for advancing the ram through at least part of a ram travel, the rapid advance ram actuator having one end contacting the ram and another end with an actuator hydraulic fluid contact surface for moving the rapid advance ram actuator relative to the frame using hydraulic fluid from the conduit system;
• wherein the ram has a chamber formed therein, and the rapid advance ram actuator is located inside the chamber.

A hydraulic crimping tool comprising:

• a head section;
• a movable adapter movably connected to the head section to move relative to the head section along an axis of translation, the movable adapter interfacing with the head section so that the adapter is held in a predetermined orientation relative to the head section when the movable adapter is moved along the axis of translation;
• and
• a hydraulic power section with a hydraulic ram connected to the movable adapter to move the adapter along the axis of translation;
• wherein at least one of the ram or movable adapter has a boss mated to a socket to couple the movable adapter and ram, and wherein the boss has a circumferential groove for holding locking means locking the movable adapter to the ram while allowing the head section to rotate freely relative to the ram.
