7 Operation
1. The electric hoist is operated using the operating handle. When operating the upper position of the switch, the load is
hoisted up. When operating the lower position, the load is lowered. Never switch directly from hoisting to lowering or vice
versa. Always stop the cable winch prior to changing directions.
2. Operate the emergency-off switch to immediately stop the cable winch in case of an emergency and to secure against
restart. To reset the device to operational status, first turn the emergency-off switch clockwise, which will unlock the red key.
The cable winch is now operational.
3.
The electric hoist is designed with limit configuration to limit stop. When load hook is hoisting up to topmost position, the
limit weight touches the up limit bracket, the microswitch of up limit bracket can cut off the circuit and make the motor stop
to insure the safety of operations. When load hook is lowering down nearly to use up the cable, the microswitch of down
limit bracket starts work and cut off the circuit and make the motor stop.
ATTENTION!
If the cable has been unwound to the point where the red indicator mark is visible, the cable
winch must be stopped. Under no circumstances should the cable be unwound past this point.
4. If the cable winch cannot hoist a load immediately, switch it off immediately to prevent damages and accidents.
5. Please be sure that the load is securely fastened to the load hook. Maintain the largest possible distance to the load and
steel cable during operation.
6. Upon lowering a load, please remember that the cable hoist may still unwind a few more centimetres after it was stopped.
Therefore, please stop in sufficient time.
7. Please be sure that the steel cable cannot be moved more than 15° to the side.
8. The cable winch can be operated with a single or double cables, therefore the permissible rated load, see Technical
Specifications, can vary.
9. After unpacking the items, check to make sure that all pieces and accessories correspond with the directions. Check to see
if the rope winch has any dents or damage, if the cable connections have any defects and if the motor shows any signs of
rain or water damage.
10. The electric pulley uses a single-phase energy power supply. The nominal voltage is 230 V + 20%, the nominal frequency
is 50 Hz + 1%. The motor must be safely grounded. In the circuitry of the power supply an over-current protection must be
installed.
11. After connecting the power supply, the pulley can then be raised and lowered in Jog-mode. One can raise and lower
start-up during a dry-run. First when the up and down movement is stable and the brakes work flawlessly, once can test the
pulley with a dummy load.
12. The surrounding area temperature should be between 5 - 40 °C. The height about sea level needs to be under 1000 m.
The area dampness should be at 30-95%.
The temperature for the storage and transport should be about 5 up to 55 °C.
Intermittent rating
This machine is designed for operating type S3 20% - 10 min (periodic intermittent operation). The relative duty cycle is
20%, which means that the device can be operated at rated load for 2.0 minutes during each operating cycle and must then
be switched off for 8.0 minutes to cool off. The device can therefore be continuously used for a duration of 20% of the total
operating cycle of 10 minutes at rated load.
Overload
• The cable winch is not suitable for continuous operation. The motor is protected from overload and overheating by a
temperature switch.
• If the permissible operating time is exceeded, the motor temperature will increase and the temperature switch will shut the
cable winch off. The temperature switch will automatically switch back on after a cooling phase.
• In case of a strain on the cable hoist with a lesser load, the operating time will increase and the cooling time will decrease.
ATTENTION!
In case of direct exposure to sunlight, the temperature of the casing will increase significantly,
which will also decrease the permissible operating time. It is therefore possible that the
temperature switch will switch off after a short time period and the cable winch will shut down.
Please wait until the device is cooled off.
