Guided Type Fall Arrester - Body Control System

摘要

A fall arrester (10) including a body (20), a pawl (18) mounted to the body (20) for movement between a disengaged position and an engaging position wherein the pawl (18) engages a catching stop (16) in a guide rail (12), a first connecting element (41) operably connected to the pawl (18), and a second connecting element (60) operably connected to the pawl (18), wherein the pawl (18) is configured to move from the disengaged position to the engaged position in response to a first predetermined force applied to the first connecting element (41) in a first direction and to move from the disengaged position to the engaged position in response to a second predetermined force applied to the second connecting element (60) in a second direction that is different than the first direction.

1. A fall arrester for use in a climbing protection system to protect a user of a ladder, a platform or the like from falls wherein the fall arrester is adapted to be used with, and to be movable along, a guide rail having catching stops engageable by the fall arrester in response to a fall by the user, the fall arrester comprising:
a body; a pawl comprising a pawl tooth, the pawl mounted to the body for movement relative to the body between an engaging position wherein the pawl tooth will engage a catching stop in the guide rail and a disengaged position wherein the pawl tooth will not engage the catching stops in the guide rail; a first connecting element operably connected to the pawl and configured to transmit force to the pawl from a user attached to the connecting element; and a second connecting element operably connected to the pawl and configured to transmit force to the pawl from a user attached to the connecting element; wherein the pawl is configured to move from the disengaged position to the engaged position in response to a first predetermined force applied to the first connecting element in a first direction, and the pawl is configured to move from the disengaged position to the engaged position in response to a second predetermined force applied to the second connecting element in a second direction that is different than the first direction.
