(4) For safe usage of wire winch type WH30 model
1) Be sure to switch off and stop conveyor when inclining or relocating it.
2) Check if brake works correctly: Turn handle clockwise and check if brake pawl makes a clicking
sound. And check if handle can be smoothly turned counterclockwise.
3) Do NOT apply oil to brake portion. (Brake does not work if oil gets in it.)
4) Since winch handle is adjustable, firmly fix it before use.
5) Wind wire around winch drum more than 3 times extra. (This procedure is necessary to prevent wire
attachment portion from directly receiving load.)
6) If WH30 has been stored or not been used for a long period, make sure that winch does not slip
before use: While winch is loaded, winch up by turning handle until drum makes 1/2-1 rotation. Then
turn handle in reverse direction and check if winch does not slip.
7) Foreign substances (mud, water, etc.) in brake portion cause brake to slip. Carefully remove them by
wiping with dry cloth etc.
8) Carefully check if wire condition is proper. (Diameter reduction exceeding 7 % of nominal diameter,
strands with kinks, etc. may cause wire breakage and unexpected accidents. In these cases replace
wire.)
9) Use WH30 within its use range and capacity.
(5) Inspection and maintenance of wire winch type WH30 model
1) Remove dirt (mud, moisture, etc.) after use.
2) Properly apply oil to brake pawl, bearing portion and wire.
3) Replace brake pawl if it has become seriously dirty or worn. For rust, gently remove it with sandpaper.
Keep in mind that brake performance will be reduced if brake surface becomes uneven.
4) Correctly replace wire as follows: Loosen hexagon head bolt. Pass wire through wire attachment hole
of drum. Then firmly retighten hexagon head bolt. Wind wire in correct direction as shown in figure
below.
(3) Use range of wire winch type WH30 model

RUNNING THE CONVEYOR
4-1. BEFORE TURNING ON START SWITCH
Before turning on start switch, be sure to check items below:
1. Loose/missing bolts or nuts:
may cause parts to come off conveyor or frame to be bent. Before operation, retighten bolts and
nuts. Supply spares if there are any missing ones.
2. Grounding:
To prevent electric shock, be sure to ground earth wire.
3. Damaged connectors or switch:
may cause electric leakage or motor to burn out due to overload etc. Replace them, if any.
4. Electrical wiring:
To prevent electric leakage or electric shock, make sure that there is no unshielded portion in
electrical wiring.
5. Frame:
Confirm full length of frame is level on top, straight and not bent in any place. Incorrect frame
condition may cause belt deviation or unexpected accidents.
6. Rotation malfunction of tail pulley or rollers:
may damage belt. Replace defective tail pulley or rollers, if any. Remove foreign substances such as
strings, if any.
7. Belt slack:
may cause belt to slip and reduce conveyor performance, and it may damage belt or pulleys. Take up
belt properly. → See “５.TAKING UP THE BELT”, p.19.
8. Inappropriate power source or voltage:
If not sure, contact appropriately qualified specialists.
■Emergency stop
If it is possible to go close to the conveyor or to work beside the conveyor, be sure
to install an emergency stop switch near the conveyor for safety. Before starting
conveyor, check an emergency stop switch for position and also check if it works
correctly.
■Start alarm
If it is not possible to supervise the operation of the full length of the conveyor
from the operating position, install a start alarm for increased safety.
CAUTION

4-2. AFTER TURNING ON START SWITCH
When the following problems occur after turning on start switch, perform as follows:
1. Belt does not run (Motor pulley does not rotate):
Turn off start switch immediately, or motor pulley may burn out. Check electrical wiring and motor
pulley. → See “10. INSPECTION AND MAINTENANCE”, p.26-29.
2. Belt is running in wrong direction:
●For machine with two-point push button 正止switch for normal directional use: If belt runs in wrong
direction, open lid of two-point bush button switch, and switch the wiring connections of Black(T) and
Red(R).
●For machine with three-point push button 正止逆switch for reversible use: Set direction of belt
travel by pressing either push button 正or 逆. When changing direction of belt travel, be sure to
press stop button 止and make sure that motor pulley has stopped completely. Then press either
push button 正or 逆.
NOTE: For machines with 200V three-phase power supply and flat type connector only (without push
button switch), if belt runs in wrong direction, disconnect plug from connector and reconnect it upside-
down.
3. Belt is not correctly aligned:
It may cause belt to become damaged or motor pulley to burn out due to overload. Adjust belt
alignment. → See“ 6. BELT ALIGNMENT ADJUSTMENT”, p.20-22.
4. Motor pulley or rollers make abnormal noise:
Contact our local agent.
5. Belt speed is different from set speed:
It is possible that belt has jammed or become slack. Check and correct belt condition.
For other problems, refer to“10. INSPECTION AND MAINTENANCE” on p.26-29 or contact our local
agent.

CAUTION
■Do NOT touch the conveyor when it is running
There is considerable risk of being caught and injured by the conveyor.
■Beware of entanglement
When working close to the conveyor, take care not to get caught in it. There is a
risk of unexpected injury.

TAKING UP THE BELT
When belt is slackened off, take up the belt following procedure below:
Move tail pulley(*2) together with take-up brackets(*3) outward by turning right and left take-up
screws(*1) clockwise with a spanner. Belt will then be taken up. When turning take-up screws(*1), adjust
them alternately, little by little, to keep their movement lengths the same.
■Belt tension
Do not take up belt too much, but only to the extent that belt does not slip on motor pulley
(drive pulley), i.e. enough to drive belt.
NOTE: Excessive belt take-up may overload motor or shorten service lives of belt and
pulleys.
NOTE: After taking up the belt, if it is not properly aligned, adjust belt alignment. → See “６. BELT
ALIGNMENT ADJUSTMENT”, p.20-22.

1. Frame:
Confirm full length of frame is level on top, straight and not bent in any place. Particularly, carefully
check frame joints. → See figures below.
2. Foreign substances on pulleys and rollers:
Check each pulley and roller for foreign substances. If any, remove them and clean pulleys and
rollers.
3. Foreign substances on belt undersurface:
Check belt undersurface for foreign substances. If any, remove them and clean belt undersurface.
4. Obstacles to belt:
Check belt for obstacles disturbing its correct travel. If any, remove or relocate them.
5. Loading condition:
Improper loading, i.e. not-centered, may cause belt deviation.

BELT ALIGNMENT ADJUSTMENT
6-1. PRIOR CHECKING
When belt is not properly aligned, check machine condition and adjust belt alignment as follows:
6-2. BELT ALIGNMENT ADJUSTMENT
1. Checking belt deviation
Check how belt is deviating before adjusting alignment. Reset positions of parts below as instructed while
running conveyor slowly, and then continue running it for a while to check any further belt deviation.
(→ See figure below.)
-Pulleys of head, tail and take-up units: Set at right angle to frame.
-Take-up pulley of take-up unit: Position and adjust it equally on right and left sides.
NOTE: It is necessary to wait until belt running
stabilizes after each adjustment step and to
adjust belt alignment little by little. Belt running
will not change immediately. Moreover, when
adjusting belt alignment, pay attention to belt
tension so that it will not be excessively loose
or tight.
