Presentation; Theory Of Operation - Tractel Minifor TR125 SY Installations-, Gebrauchs- Und Wartungsanleitung

2. PRESENTATION

2.1. Theory of operation

The Minifor™ TR125 SY is a portable electric hoist
for lifting applications, implementing a feed-through
Minifor™ synthetic rope operating through a self-
gripping system giving potentially unlimited height of lift
with the Minifor™ synthetic rope.
The synthetic rope drive system used with the Minifor™
hoist is formed by a special drive pulley, two guide
rollers and two grabs.
The grabs lock the Minifor™ synthetic rope in the drive
pulley whatever the load. In addition to the effect of the
grabs, the locking action on the Minifor™ hoist synthetic
rope in the drive 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™ TR125 SY hoist must only be used with
the Minifor™ synthetic rope of the required diameter
(see specifications) to ensure complete safety and
correct operation.
Tractel declines any
®
consequences arising from use of the hoist with a
synthetic rope other than the Minifor™ synthetic rope.
Each Minifor™ TR125 SY hoist is dynamically tested
before dispatch to 110% of the working load limit.

2.4. Description
Figure 2 on page A shows a standard Minifor™
TR125 SY in the most currently used working position,
ready to operate, suspended to a ring. 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 request, the unit can be
supplied with different control and power supply cable
lengths. Each unit carries a serial number on the front
panel of the casing. The complete number (including
letter) must be given whenever requesting spare parts
or repairs.
Regularly check that all the labels are in place and can
be easily read.
The length of the Minifor™ rope is marked on a label
placed on the stitching of the hook fastening loop (see
§ 16.3).
All the Minifor™ TR125 SY hoists are supplied with a
3-control button-type control pendant (fig. 3, page A):
"Up", "Down" and "Emergency stop".
NOTE : the "Up" and "Down" directions are
represented on the corres- ponding control button by an
arrow pointing in the direction of the controlled
movement, with the unit held in its pendant position
(see fig. 3, page A).
