ISC LH-ALF Material Handling Pulley (One Way Locking) (RP433A)
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).
