2.1) Theory of operation

The Minifor™TR10SY is a portable electric
hoist for lifting applications, implementing a
feed-through
operating through a self-gripping system
giving potentially unlimited height of lift with
the Minifor™ synthetic rope.
The synthetic rope conveying system
comprises a special pulley in which the
Minifor™ is clamped under the effect of the
load, and two swivel rollers.
A pre-clamping spring, acting on the roller,
ensures that even when not under load, the
GB
wire rope is held firmly by the pulley. Over and
above the effect of the preclamping spring, the
gripping of the Minifor™ synthetic rope on
the conveying pulley is proportional to the
load.
This technical design ensures a high level
of safety provided the instructions given in this
manual in section 5) "Anchoring and rigging
arrangements" are carefully followed.
The Minifor™ TR10SY hoist must only be
used with the Minifor™ synthetic wire rope of
the required diameter (see specifications) to
ensure complete safety and correct operation.
TRACTEL ® declines any responsibility for
any consequences arising from use of the
hoist with a synthetic rope other than the
Minifor™ synthetic rope.

dynamically tested before dispatch to 110 %
of the working load limit.

2.4) Description
Figure 2 on page A shows a standard
Minifor™ TR10SY in the most currently used
working position, ready to operate, suspended
to a fastening clamp on beam. The standard
hoist is supplied with an electrical control
cable with button-type control pendant (fig. 2,
page A) and an electric power cable. On
is
request, the unit can be supplied with different
control and power supply cable lengths. Each
unit carries a serial number on the front panel
