ALF
The ALF is a fall arrest device, which locks the rotating wheel in either direction in the
event of a rapid downwards movement (descending too fast, fall or loss of balance) irre-
spective of the direction of travel of the rope. This product is designed to assist climbing
a ladder or structures. It is designed for use on ropes courses, in industrial safety, or
sport climbing activities. The ALF must only be used with ISC approved
Ø
11mm (7/16”)
rope (in Europe semi-static EN1891:1998 (A)). See [ISC Approved Rope] table for more
information.

[B] Care and Maintenance
A visual inspection should be made before, during and after use. The ALF must be
opened and inspected by a trained, competent person, authorised by the manufacturer
(ISC) at a minimum schedule of every 12 months. The frequency of inspections can be
increased to reflect applicable industry guidance, local legislation and intensity of use.
[C] ALF Use
1. The user must always be below the highest anchor point.
2. The rope can be a continuous loop with 2 knots such that when one user has reached
the top of the ladder, the next user may attach to the knot at the bottom of the ladder.
Only one person may use the system at any one time. ALF can be secured at the top of
the system or at the bottom
3. ISC recommend the use of RP066 pulley at the opposite end of the system. When
setting up an ALF system in this way, ISC recommend a tension of between 10kg & 20kg
of force. Attachment knots (inc. connectors) should be a maximum of 300mm
4. The correct rope path must be followed when threading the device.
5. The user can be attached to one end of the rope, whilst a second person holds the
remainder of the rope to take in the slack.
6. Work as close to directly below the anchor point as possible to avoid swing-fall inju-
ries. The ALF should be positioned so that the fall path is unobstructed.
7. The user must be secured to the system by the fall arrest attachment point on a full
body harness.
8. Maximum user weight 140kg (310lb.) Minimum user weight 15kg (33lb).
9. A pre-use check should be made by pulling sharply down on the rope to check locking
function. this should be applied to both sides. Non locking devices should be removed.
[D] ALF Misuse
1. Do not use a sit style harness for fall arrest
2. Do not climb above the highest anchor point
3. Do not use if rope is threaded incorrectly
4. Care should be taken not to load the ALF across its minor axis or against its axles
across a structure or anchor point
R-ALF
The R-ALF is designed for use as part of a work positioning or rescue system in industrial
safety, rescue, or tree climbing situations. The R-ALF will lock in either direction if the
rope is released. To unlock the rope, pull on the tail of the rope and continue to haul. If
the rope is released during lowering, the load will be arrested.
