Before using the TIRFOR winch, it is essential for the safe and correct operation of the
equipment that these instructions be read and fully understood and that all the instructions
are followed. These instructions should be made available to every operator.
The TIRFOR winch allows the operator to carry out work with complete safety. Ensure
that this winch is only handed over for use to an operator who is trained to operate it in a
Never use a winch, which is not in good working condition. Replace any worn or damaged
wire rope. Continuous monitoring of the condition of the winch, its wire rope and anchor
pin is an important safety consideration.
Never attempt to overload the winch.
Standard TIRFOR winches are not designed for use in explosive atmospheres.
The TIRFOR winch is a hand-operated pulling machine for end of bridge anchors.
The unique feature of the TIRFOR winch, is the principle of operation directly on the wire
rope, which passes through the mechanism rather than being reeled onto a drum of a
hoist or conventional winch. The pull is applied by means of two pairs of self-energized
jaws, which exert a grip on the wire rope in proportion to the load being lifted or pulled. A
telescopic operating lever fitted to either the forward or the reverse lever transmits the
effort to the jaw mechanism to give forward or reverse movement of the wire rope.
The winch is fitted with an anchor pin, so that it can be secured quickly to the anchor
block on the anchor beam.
Each winch is supplied with a telescopic operating handle, and usually with a 40ft
standard length of special TIRFOR MAXIFLEX wire rope fitted with a open socket form
end and wound onto a metal reel.
TIRFOR MAXIFLEX wire rope has been specially designed to meet the particular
requirements of the TIRFOR winch. The safe operation of winches used with wire rope
other than TIRFOR MAXIFLEX wire rope cannot be guaranteed.
