If the voltage is less than 5%, the motor will not reach the operating voltage; thus, before
using the hoist, kindly check if the voltage is normal or not.

III．INSTALLATION OF HOIST
3-1. Mono-rail
3-1-1. The width of I / H-beam girder should be >= (the base width of trolley
wheel + 2 to 4 mm gap) shown as the following:
3-1-2. When one end of girder is opened, the hoist and trolley could be combined and
installed from the opening end
3-1-3. When both ends of girder are closed, or the end of girder cannot be opened to
cause hoist to fail entering-in, please release the trolley plates and install it.
3-2. Double-rail
After hoist and trolley are combined, please set it on the traversing rail directly.
REMARK: There is an eccentricity self-regulation device for the axle of double-rail hoist,
so the movement of the trolley wheel can be balanced on the rail. When main hoist has
no loading, the four trolley wheels may not touch to the rail simultaneously; however,
this circumstance will not be happened after loading.
3-3. Lifting hoist (Cargo elevator)
Lifting cabin should be elevated to the top-end. Kindly move the hoist in order to keep
the centre of gravity of hook is the same as the vertical line of lifting box; then, please fix
the hoist horizontally and correctly.
IV．TESTING
4-1. Confirmation before running
4-1-1. The auxiliary supporting line of the control pendent should be tied firmly and
correctly, to avoid the cable being deformed under force
4-1-2. The position of control pendent should be at 1 metre distance from the floor
4-1-3 A stable voltage is normally (R, S, T,) 3-phase averaged range: 5%~+5%; if the voltage
is insufficient, will cause the motor burn up

4-2. Confirmation before un-load running
4-2-1. Testing the control pendent:
Please press the button “UP” first when testing; do NOT press the button “DOWN”
first. After pressing “UP”, the hook will be lifted up, indicating that it has no
problem; if the hook moves downward, the power connection of hoist is NOT
correct (error phase sequence). As a result, please change two wires of R, S, T,
alternatively, and repeat the above steps until this problem has been solved. If the
hoist was used with a wrong wire-connection (error phase sequence), the limit
switch will be INVALID and it may cause the wire-rope BROKEN or severe damage
of the hoist accidents; therefore, be careful and pay attention to this condition
4-2-2. Press the button switch to keep the hook lifting up:
When hook reaches the position of UP LIMIT, the limit-switch will start to stop the
hook automatically; please press “DOWN” to make sure if the hook is moved
downward
4-2-3. To let the hoist load 100 kg-200 kg loading and move full-distance up and down,
please check the following when moving:
(1) Is the rail proper?
(2) Is any interference for cable?
(3) Is the space enough between the hook and building?
(4) Could the hoist touch the building?
4-3. Confirmation before full-load running
4-3-1. First, please test its lifting up and down movements, and check if the sliding is
appropriate or not after braking?
4-3-2. Is it stable or not? When the hoist is moving?
4-3-3. When hoist is moving, test the voltage of trolley. The voltage should NOT exceed 7%
of the voltage of motor that shows on the nameplate of motor
4-4. Confirmation after testing your hoist
4-4-1. After testing the hoist, please check the rope press block on the drum, if it is
loosened or not?
4-4-2. Check the traversing and runway rail, if they are loosened or not?
4-4-3. Check the temperature of motors, if they are normal or not?
4-5. Confirmation of safety device
4-5-1. Upper- and lower-limit-switch:
Use the spiral limit-switch to ensure that the wire rope would stop when it reaches
upper- and lower-limit during operation

4-5-2. Drum-typed strut rope guide:
Please use the two screws to adjust the rope guide as to touch the wire rope on the
drum; adjust the rope guide limit-switch to ensure that the rope is winded into the
groove, if the rope is out of the groove; press the button (down) so that the rope
could return to its normal way for operation
4-5-3. Overload protection device could prevent over-loading:
In the case of excessive over-loading, the protection device will disconnect the
