1. INTRODUCTION AND DESCRIPTION
OF EQUIPMENT
The JOCKEY ™ 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
® machine is the prin-ciple 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, depen-
ding on the model, so that it can be secured quickly to any
suitable anchor point.
The JOCKEY
™ machines, intended for lifting and pulling
materials, are available in two models :
– Jockey
™ capacity 300 kg,
– Jockey ™ J5 capacity 500 kg.
Jockey ™ model : the standard kit comprises a machine
with its operating handle, a 10 m length of special
Jockey
™ wire rope fitted with a hook with safety catch and
two wire rope slings, one 1m in length and the other 2 m
in length. The equipment is contained in a sturdy carton
for carrying and storing the kit. Other lengths of wire rope
are available on special order.
Jockey ™ J5 model : the J5 is available in two standard kits
comprising a machine with its operating handle and with:
- either a 10m length of special wire rope fitted with a
hook with safety catch and two anchor slings of 2m in
length;
- or a 10m length of special wire rope fitted with a hook
with safety catch, two anchor slings of 2m in length and
pulley block allowing the capacity of the machine to be
doubled.
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 spe-
cially designed to meet the particular requirements of
the JOCKEY
™ machine. The manufacturer does not
guarantee the safe operation of machines used with
wire rope other than TIRFOR
® wire rope.
