1. PRESENTATION

1.1 Theory of operation

The minifor
feed-through wire rope for lifting and pulling
operations. The hoist implements a self-clamping
drive system providing unlimited lifting wire rope travel.
The drive system is formed by a pulley with
specially-shaped groove in which the wire rope is
clamped under the effect of the load by two swivel
rollers.
A pre-clamping spring which acts on the rollers
maintains the wire rope on the pulley when no load
is attached to the system. Beyond the action of
the pre-clamping spring, the clamping action of the
GB
wire rope on the drive pulley is proportional to the
load.
The technical design of the system ensures a
high degree of safety provided the instructions
given in this manual in the section entitled «
Anchoring the hoist – Installation diagrams » are
strictly observed.

1.3 Description and markings

Figure 1 shows a standard minifor
frequently used operating position, ready for
operation, suspended on a clamp secured to a
beam. The standard hoist is supplied with a 2.5m
electric control cable with control box (Fig. 2) and
a 0.50 m electrical power supply cable. On request,
the unit can be supplied with different control and
power supply cable lengths. Each unit carries a serial
number on the top 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 lifting wire rope is marked on
the end sleeve in the hook. If necessary, check
the wire rope length as it is possible that the wire
rope may have been shortened since the unit was
delivered. All the minifor
