7) Operating the hoist
The hoist is operated by pressing on either the
“Up” or “Down” button on the control box
(fig. 3, page A). The control box must always
be held in the vertical position, hanging on
its control cable. Never turn over the control
box (control cable entry downward) as this can
result in control mistakes.
When the “Up” or “Down” button is released,
the movement stops.
IMPORTANT: For lifting operations at
great heights using a single phase minifor™
TR10SY hoist, the unit should be stopped for
around 15 minutes after 10 minutes of
operation for the minifor™ TR10SY 230V
operating at 15m/min. and after 15 minutes of
operation for the minifor™ TR10SY operating
at 30m/min.
DANGER: The temperature of the
hoist casing, when the unit is operating, can
reach 80°C. Beware that any contact with the
hoist casing can result in severe burns.
The red emergency stop button is used to
immediately stop movement in the event of a
malfunction of the “Up” or “Down” button
(item 1, fig. 3, page A). (see §9: Safety
devices).
The following precautions must be taken
when performing up or down movements:
- the load should not swing or turn,
- keep all possible obstacles at a distance
from the synthetic rope and from the load,
- check that the loose strand is free along
its entire length,
- do not allow the loaded strand to become
loose if the load is not stably bearing on
a sufficiently strong support,
- do not apply short successive actions on
the pushbuttons,
- make sure that the load to be moved is
not attached or blocked by anything
external to the lifting device.
DANGER: you must absolutely keep
the slack section of synthetic rope at a
distance from the loaded rope to keep it from
tangling with the loaded rope section.
For the same reasons, the loose wire rope
strand must be kept away from any
obstacle which could catch it and you
should be careful to prevent the loose
strand from becoming tangled in itself; this
could result in preventing the low limit stop
attached to the loose strand from reaching
the stopping mechanisms (limit stop levers)
on the unit. Blockage of the loose strand
when moving up (load moving down) can
result in rupture of the synthetic rope and
falling of the load.
A deformation of the Minifor™ synthetic rope
can also result in jamming of the hoist.
Whatever the cause of a jam, be sure to
immediately stop the maneuver.
The limit stops are not control components
but safety components. These should never
be used intentionally in this respect and only
serve as stopping mechanisms in the event
of unintentional overshoot of the planned
travel distance.
Never remain stationed or work under a load.
Mark out the working area using barriers to
prevent anyone from passing under the load.
Never use the hoist to lift or carry persons.
8) Shutdown - Storage
Never disconnect the synthetic rope
hook from the load until the load is bearing
and stable on a fixed support of sufficient
strength.
The hoist can remain in position provided
it is properly sheltered from weather and
located in a dry location. Disconnect the unit
electrically when not in use.
Make sure the hoist cannot be used by
unauthorized persons.
For storage, the unit can be stored in its case.
The Minifor™ synthetic rope must be removed
from the hoist and wound on its winder or on
its reel. The Minifor™ synthetic rope must be
