DUAL DIRECTIONAL CABLE ACTUATED EMERGENCY STOP DEVICE

摘要

A dual directional cable actuated emergency stop device has two shaft assemblies attachable to two respective cables spanning along an industrial and/or manufacturing operation. The first shaft assembly is slideably disposed within a housing structure and movable relative to said housing structure along a first path in a direction parallel to an axial centerline of said shaft in response to a force exerted by a cable attached to an end of said first shaft. The second shaft assembly is slideably disposed within said housing structure and movable relative to said housing structure along a second path in a direction parallel to an axial centerline of said shaft and opposite movement of said first shaft, in response to a force exerted by a cable attached to an end of said second shaft. A switch operator movable along a second path between a first position and a second position is responsive to movement of said first or second shaft assemblies and is also responsive to a mechanism for locking the switch operator in a second position after said switch operator moves into a second position. At least one electrical switch associated with the device can be actuated when the switch operator is in said second position and deactuated when said switch operator is in said first position. Windows formed on the device housing cover allow a user to monitor tension of first or second cables attached to respective first and second shaft assemblies, based on the position of a cam associated with each shaft assembly.
