General
The electric rope hoist is an ideal appliance in your garage, warehouse or other
similar locations for hoisting all kinds of loads.
This rope hoist can not be used for transporting hot molten masses. It can not be
used for operating in aggressive environments and low temperatures.
The group of mechanisms is M1.
The useful life of the electric rope hoist is above 8000 cycles (except wearing
parts). If the hoist has run 8000 cycles, it must have all mechanisms inspected and
maintained.
Read and understand the instruction manual completely and clearly before using
the hoist.
Ensure that operators know how the machine works and how it should be
operated.
The user shall always work in compliance with the operating instructions.
The electric rope hoist 1s not designed for continuous use. The work rate 15
intermittent periodic duty.
The rated load of the machine does not vary with the position of the load.
Safety instructions
1.
I~
en
© 0 1 SS
Always confirm that the service voltage corresponds to the voltage on the rating
plate. Inappropriate supply voltage may result in working abnormally or personal
Injury.
Your socket plug must be grounded and at the same time, your power supply
system must be supplied with a leakage circuit breaker,
It is forbidden to lift loads above the rated load of the hoist.
Use the device only for its intended purpose. Never carry persons with the hoist.
Do not disconnect the plug by pulling the cord. Keep the cord out of heat, oil and
sharp edges.
Do not try to lift fixed or obstructed loads.
Pull out the plug when the hoist is not in use.
Keep children and other unauthorized persons away from the machine.
Do not side-pull loads. Avoid swinging the load or hook.
10. Make sure the hook travels at the direction same with your operation intention.
11. Inspect the electric rope hoist and switches regularly to make sure they are in
good operating conditions.
12. Have your tool repaired by an expert; otherwise it may cause danger for the user.
13. Avoid excessive inching.
14, It is not allowed for you attention to be diverted from operating the hoist,
15. Do not stand or work under a lifted load.
Statutory statement within the safety information
* This appliance 1s not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the appliance by a person responsible for
their safety, Children should be supervised to ensure that they do not play with the appliance.
Installation and use
Unpacking
After opening the carton, carefully inspect the hoist frame, cords, hooks and control
units, etc. for damages, which may have occurred during shipment.
Installation (See Figure 4)
The hoist is provided with an installation system that allows it to be mounted on a
rectangular beam.
The dimension of the rectangular beam must be in accordance with the position and
dimension of the installation holes of the hoist and its strength can hold the rated load.
lt is recommended to turn to a skilled technician for help and inspect the solidity of
the beam structure.
The fastening screw must be properly tightened. Before utilization, a skilled
technician should check that the support system and the coupling of the hoist are well
sized.
Utilization of pulley block (See Figure 5 and Figure 6.)
The hoist 1s provided with an extra pulley and hook, and when they are used correctly,
the machine can hoist double load.
Assemble the pulley with help of bolts as shown in the picture.
The hook originally fixed on the machine can be attached to the rack’s opening which
is designed for this purpose. With help of 2 steel cables to lift the load, the machine 1s
now capable of hoisting a double load.

Operating instructions
1. Before the machine is used for the first time, remove the adhesive tape for fixing
steel cables from the cable drum.
2. The value of the equivalent sound emission pressure level at the operator's
position 1s lower than 70dB.
3. For the machine, the supplying power requirement 1s as follows: the voltage 1s
rated voltage +10% and the frequency 1s rated frequency +1%,
4. The hoist is used at ambient temperature of 0°C ~40°C, and the relative humidity
of air at 25°C is not higher than 85%.. The sea level where it is used is not higher
than 1000m.
5. The transportation and storage temperature of the hoist may be above -25°C and
below 55°C, with the highest temperature of not higher than 70°C.
6. The user shall lift the load from the ground with the lowest seed. When a heavy
weight is lifted from the ground, the steel cable shall be in tense state instead of
slack state.
7. The motor of the hoist is equipped with a overheat switch. During operating, the
hoist may stop running, and it will become operational again only after a break for
the motor to cool down.
8. The electric rope hoist 1s not supphed with any overload stop. Therefore, 1f 1t 1s
unable to lift a heavy weight, do not insist and let the motor cool down, since that
means the load exceeds the maximum capacity of the hoist.
9. Do not leave a load supported by the hoist unattended unless specific precautions
have been taken.
10. Provide a 10A fuse or 10A over-current protector to protect your power supply
system.
11.Do not use limit switches as routine operating stop switches. They are only
emergency devices.
12. Before using this hoist, make sure that the steel cable is correctly winded around
the rope drum with the pitch equal to the diameter of the steel cable. (See Fig. 2).
13. Make sure that the load 1s properly secured to the lifting hook (7) or the pulley and
the operator shall always keep certain distance with the load and the steel cable (6).
Operation
e Check if the emergency stop switch (11) 1s pressed. Turn the red button clockwise
to release it.
Press the push button À (10) to lift the load
Press the push button ¥ (10) to lower the load
For the up limited system, when the hoisted load 1s almost at the top position, the
limit block (4) will move the spacing collar (3) upwards, and then a switch in the
motor will now be engaged to stop the upward movement of the motor.
For the down limited system, when the hoisted load is almost at the bottom
position (about two turns of cable around the drum), the down limit pole (11) will
move, and then another switch in the motor will make the downward movement of
the motor stop. In case the moving direction is different with that it is being
controlled (caused by the steel cable hold down by those directly beside it), the
down limited system may also be actuated.
When the emergency stop switch 1s pressed, the hoist will be stopped.
In case of an emergency, immediately press the red emergency stop switch (9) to
stop the machine. When the emergency stop switch 1s actuated, operating the hoist
is not possible.

Periodic inspection and maintenance
Attention! Always make sure that the machine is not connected to the main
electricity network before any mechanism maintenance is carried out.
Hereinafter, per cycle means that the operator operates the load up and down for
one time. Periodic check means that a part needs to be inspected after the hoist
working per 100 cycles.
Periodically make sure the limit switches function properly. The limited system
should be tested as follows:
When the hoist 1s carrying out hoisting operation (without load), move the spacing
collar (3) towards the rising direction, the motor of the machine must stops
running.
When the hoist 1s carrying out lowering operation, move the down limit pole, the
motor must stops running.
Periodically check the power cords and control cords.
Lubricate the steel cable and the pulley after per 200 cycles.
Confirm 1f the steel cable is in good operating mode after per 30 cycles. If there
are any damages on the steel cable (see Figure 3), replace the steel cable
immediately in accordance with the requirements in the technical data table.
Inspect if the screws securing the bracket and the pulley are well tightened after
per 1000 cycles
Check the hook and the pulley after per 1000 cycles to ensure that they are in good
operating modes.
Before using the electric rope hoist every time, inspect the emergency stop switch
and its button panel to ensure they are in good operating modes.
Inspect the braking system after per 100 cycles. If there are abnormal noises in the
motor or the hoist 15 unable to hold the rated load, the braking system must be
overhauled.
Replace damaged and worn parts, and keep necessary maintenance record.
