More Information
Summary:A hydraulic actuation device includes a tool, an actuation part 21 having a pressure oil supply mechanism 30 configured to send pressure oil from an oil chamber 28 to the tool and return return oil from the tool to the oil chamber 28, an operation handle 70 for adjusting oil passages for the pressure oil and the return oil in the pressure oil supply mechanism 30 and configured to be able to be moved from an initial position, and biasing means configured to bias the operation handle 70 toward the initial position when no external force is applied to the operation handle 70. When the operation handle 70 moves from the initial position, the tool is actuated by the actuation part 21. When the operation handle 70 is returned to the initial position by the biasing means, operation of the tool by the actuation part 21 is stopped.
