ISC ABRALF Pulley System

Durham Lifting’s Abtech ABRALF Pulley System is designed for use in Rescue, Confined Space working and Work Suspension Systems. The RALF Pulley has an over-speed brake built in so that the Pulley will lock on and hold when a fall occurs. The load rated Becket Eye on the RALF means that it can be used in combination with Prussik Pulleys to create a 3 : 1 or 5 : 1 Mechanical Advantage System. Conformance: CE 0120 ANSI Z359 :4: 2007
