1. INTRODUCTION AND DESCRIPTION
OF EQUIPMENT
The tirfor
®
machine is a hand-operated lifting and pulling
machine. It is versatile, portable and multi-purpose,
not only for pulling and lifting but also for lowering,
tensioning and guying.
The originality of the tirfor
®
machine 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-energised 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 machine is fitted with a hook or anchor pin,
depending on the model, so that it can be secured
quickly to any suitable anchor point.
tirfor
®
machines, intended for lifting and pulling materials,
are available in two ranges each with three models of
different capacities:
– T-500D range for light duty applications (with safety
release catch).
– TU range for heavy duty applications (with safety
release catch).
Each machine is supplied with a telescopic operating
handle, and usually with a 20 m standard length of
special tirfor
®
wire rope fitted with a safety hook and
wound onto a metal reeler. Longer or shorter lengths
of wire rope are available on request.
This manual together with a guarantee card are supplied
with each machine, as well as the CE declaration
of conformity.
IMPORTANT :
tirfor
®
wire rope has been specially
designed to meet the particular requirements of the
tirfor
®
machine.
The manufacturer does not guarantee the safe
operation of machines used with wire rope other
than tirfor
®
wire rope.
2. ASSEMBLY DRAWINGS
Various ways of rigging are shown in Figs. 2.1, 2.2, 2.3
and 2.4. Figs. 4 and 5 show particular arrangements
(one forbidden and the other recommended).
The machine may be anchored to a fixed point with the
wire rope travelling towards the machine (Figs. 2.1, 2.2,
2.3), or travel along the wire rope, with the load, the wire
rope itself anchored to a fixed point (Fig. 2.4).
In example 2.2, the maximum working load of the pulley
and the anchor point should be equal to or greater than
twice the load.
N.B. Whatever the rigging arrangement, and if the
machine is anchored directly to a fixed point, ensure
that there are no obstructions around the machine
which could prevent the wire rope, the machine and
anchor from operating in a straight line. It is therefore
recommended to use a sling of an appropriate capacity
between the anchor point and the machine (Fig. 3).
