The approved rope for use with the ALF is ISC workLINE (11mm Low Stretch Kernmantle, EN1891A).RP433
The LH-ALF has been designed for material handling (not recommended for use with people). The LH-ALF has brake pawls on one side only which means that there is no restriction on hauling speed/movement (on the normal two-way locking R-ALF device, unintentional locking can occur when hauling too quickly).
The one-way locking LH-ALF is therefore ideal in a setting where a user needs to haul quickly, such as when unloading materials from a supply vessel at an offshore wind turbine.
The LH-ALF can be used in a 2:1 hauling system (SWL 250kg) and is available as kit:
RP433 LH-ALF 
RP063 Medium Aluminium Prussik Pulley 
KH407 Pear Scaffold Karabiner (Anchor Connector) 
KH221 Aluminium Oval Karabiner (Supersafe) 
The above kit is supplied in a carry bag, with sufficient rope to achieve a 10m (32ft) Height of Lift as standard. Other Heights of Lift and bespoke kits are available- please contact us for further information.
