Operating Conditions; Test Run; Raising A Load - unicraft ESW Series Operating Instructions Manual

When the unwind rope limiter switches off the electrical
cable winch, the circuit is interrupted and the machine is
stopped.
If the electrical cable winch cannot lift a weight immedi-
ately, switch off the electrical cable winch immediately to
avoid damage and accidents.
Ensure that the suspension rope is not deflected by more
than 15° and is not pulled or fastened over sharp edges!
(Risk of damage to the rope).
The direction of unwinding must always correspond to
the switch position, otherwise the electrical limit switch
will not function if it is not observed and serious damage
may be caused to the unit!
If the electrical cable winch is not in operation, it must al-
ways be disconnected from the mains supply.

8.1 Operating conditions

ESW
Temperature range [°C]
Operating altitude
Operating environment
The working area must be dry, fire and explosion pro-
tected and free of any corrosive or poisonous sub-
stances.
The electrical cable winch must not be used to lift or
move dangerous goods such as molten, poisonous or ra-
dioactive materials.
The electrical cable winch may be used outdoors, but not
in heavy rain.
Work duty: S3-20% 10 min
Working cycle 10 minutes, of which 2 minutes operating
time and 8 minutes resting time for cooling down.

8.2 Test run

Before using the the electrical cable winch to lift a load, a
no-load test should be carried out to test all functions. In
particular, the function of the raising and lowering limits
should be tested.

8.3 Raising a load

ATTENTION!
The electrical cable winch may only be connected to
230 V alternating current!
ATTENTION!
- Take care that no person is in vicinity or in line of
the cable behind the the electrical cable winch,
when the the electrical cable winch is under load.
- Make sure that the route of load is free from
barriers.
- Avoid swinging the load.
- The limit switches must not be approached during
operation.
NOTE!
- Do not wrap the rope around the load.
- Check the position of the centre of gravity of the at-
tachment point to prevent movement and slipping of
the load.
- Lifting equipment (eye, chain or similar) must be
loosely positioned at the bottom of the hook.
- The tip of the hook must not be loaded.
- Close the fuse.
NOTE!
- The operator must have sufficient stability and free-
dom of movement.
- The electrical cable winch must be able to swing
freely in the pulling direction.
- Limit switch-off: When the limit of the lifting travel is
reached, the power supply switches off automati-
cally and the load hook stops.
- The load hook is designed in such a way that it de-
forms when overloaded and does not break brittle.
Step 1: Check that the electrical cable winchand the rope
are in perfect and undamaged condition.
Step 2: Attach the winch load hook to a suitable load at-
tachment point and check that the hook securing
device is closed.
Step 3: Check that the load is securely attached to the
hook. Always stay away from the load and steel
cable during operation.
Step 4: First drive upwards only until the load rope is ten-
sioned.
Step 5: First lift the load only a small piece and check
that the rope and load are stable.
Step 6: Lift the load slowly and evenly.
