APS 251 fall arrester

Model APS 251 · Alko Plus

Overview

ALKO PLUS provides a vast range of Fall Arresters which have a wide application of usage in fall arrest while climbing, and in restraint while working on rooftops, platforms and inclined planes. All these systems have uniquely designed rope grabs that grab onto the anchorage line on which they move, thus arresting the fall immediately.

Key features

ALKO PLUS Fall Arrester APS 251 is a detachable Rope Grab Device, made up of high strength steel.
It moves freely along the polyamide twisted rope anchorage line (14mm to 16mm dia), attached at its eye with the user, while he moves up and down.
The rope grab immediately ‘grabs’ on to the line in the event of a fall, thereby arresting the fall.
ALKO PLUS Fall Arrester is provided with a unique Gravity Locking system that prevents incorrect usage.
It is also equipped with a double security opening system and hence will not open unless a deliberate action taken.
