Abstract
A fall arrest blockhas a spindle on which a length of lifelineis wound. In normal use, the lifeline (preferably webbing) retracts onto and extends from a drum housing, as the workman moves towards and away from a secure point to which the housing is attached. In the event of a fall, an inertia mechanism sensitive to acceleration of the spindle operates to lock a locking mechanism to hold the spindle against further rotation. An energy absorbing linkis built into the webbing, close to a hookto which the workman is attached. The energy absorbing linkincludes a section of lifeline that is stretchable, but non-elastic. The locking mechanism includes a toothed ratchet wheel that is engaged by a pawl in order to lock the spindle rotation. The toothed ratchet wheel is part of a unitary body with the spindle.
