The cable hoist is designed with limit configuration to limit stop. When load hook (12) is
hoisting up to topmost position, the stopper (10) touch the lift limit bracket (8), the micro
switch of lift limit bracket (8) can cut off the circuit and make the motor stop to insure the
safety of operations. When load hook (12) is lowering down nearly to use up the cable (7),
the micro switch of down limit bracket (9) start work and cut off the circuit and make the
motor stop.
Attention! If the cable has been unwound to the point where the red micro
switch is visible, the cable hoist must be stopped. Under no circumstances
should the cable be unwound past this point'
If the cable hoist cannot hoist a load immediately, switch it off immediately to prevent
damages and accidents.
Please be sure that the load is securely fastened to the load hook (12-13). Maintain the
largest possible distance to the load and steel cable (7) during operation.
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.
Please be sure that the steel cable (7) cannot be moved more than 15° to the side.
The cable hoist can be operated with a single or double cables, therefore the permissible
rated load, see Technical Specifications, can vary.
After unpacking the items, check to make sure that all pieces and accessories correspond
with the directions. Check to see if the cable hoist has any dents or damage, if the cable
connections have any defects and if the motor shows any signs of rain or water damage.
The cable hoist uses a single-phase energy power supply. The nominal voltage is 230V +
20%, the nominal frequency is 50Hz + 1%. The motor must be safely grounded. In the
circuitry of the power supply an over-current protection must be installed.
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.
9.1
Intermittent rating
T
his
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.
9.2
Overload (Only for POWX901-POWX902-POWX903)
The
cable hoist
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 hoist off. The temperature switch
w
ill 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 hoist will shut down.
Please wait until the device is cooled off.
