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
