1. INTRODUCTION AND DESCRIPTION OF EQUIP-
MENT
The TIRFOR ® machine is a hand-operated lifting and
pulling machine. It is versatile, portable and multi-pur-
pose, not only for pulling and lifting but also for lowering,
tensioning and guying.
The originality of the TIRFOR
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 rever-
se movement of the wire rope.
The machine is fitted with a hook or anchor pin, depen-
ding 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 spe-

2. RIGGING ARRANGEMENTS

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
(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
