CONTROL SYSTEM FOR TOOL COUPLING

摘要

A control system for a tool coupling of the type that attaches a tool to an excavator dipper stick and provides for rotation of the tool with respect to the dipper stick about an axis, and further provides for tilting of the tool, includes a rotation sensor and a tilt sensor. The rotation sensor is mounted on the coupling for determining the amount of rotation of the tool with respect to the dipper stick about an axis. The tilt sensor is mounted on the coupling for determining the amount of tilt of the tool with respect to gravity. A control is responsive to the rotation sensor and to the tilt sensor for determining the orientation of the tool.
