CONTROL SYSTEM FOR THE TOOL COUPLING OF AN EXCAVATOR

摘要

A control system for a tool coupling (37) of the type that attaches a tool (36) to an excavator dipper stick (26) 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 (82) and a tilt sensor (85). 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 (86) is responsive to the rotation sensor and to the tilt sensor for determining the orientation of the tool.
