SAFETY DEVICES
3.17.9.1
All TIRFOR winches incorporate a shear pin system. In case of overload, the pin fitted to
the forward operating lever, shears and prevents further operations. Reverse operation is
still possible to enable the wire rope to be slackened.
Should the shear pin shear, refer to Chapter 10 procedure 10.30 for replacement
3.17.9.2
instructions.
3.17.10.1 TIRFOR winch Model T-532D is fitted with a two handed rope release system, which
requires deliberate operation by the user to release the winch. (See Para 3.17.4).
3.18.1.1
To guarantee the safe operation of TIRFOR winches, it is essential to use them
exclusively with TIRFOR MAXIFLEX wire rope, which has been specially designed to
meet the requirements of the TIRFOR winch.
3.18.1.2
TIRFOR MAXIFLEX wire ropes have a red strand, which is visible on new rope. One end
of the wire rope has an end fitting (Figure 3. 83. (A)), the other end of the wire rope is
fused and tapered (Figure 3. 83. (B)).
3.18.1.3
A wire rope in good condition is a guarantee of safety, to the same extent as a winch in
good condition. It is necessary to continuously monitor the state of the wire rope, and to
clean and oil it with a rag soaked with motor oil or grease.
