5. Assembly, wiring and test run
WARNING : ALWAYS make sure that the load supporting structures and load attaching
device are strong enough to hold the weight of load and hoist.
Have all assembly works by the authorized people. Off-limits to unauthorized
people in assembly works area.
5.1 Assembly
For detailed assembly instructions, refer to the urethane wheel crane’s assembly manual. The end
carriage can be easily set on the travel rails with the following procedure.
<Low-head type carriage>
(a) Detach all track wheels and axles from the end carriage as shown in Fig. 1.
The end carriage frame can be erected without detaching it from the girder. Reassemble the track
wheels and axles when the end carriage is in position.
There is always the risk of the hoist and trolley moving when installing, therefore it is easy to fix
them to the girder.Also, pay attention when assembling with the power supply cable, junction cable
and other accessories.
(b) Installing as shown in Fig. 1.

(c) Precautions in installation (Refer to Fig. 2)
Pay attention to the following points when coupling the end carriage to the girder on site.
Fig. 2
Keep the end carriage frames parallel (Aand B should be the same).
Minimize any discrepancy between the left and right end carriage frames position (D should be
minimized).
WARNING : If improperly assembled and installed, the crane will repeatedly strike the
stopper on the travel rail. This may cause bolts to loosen or other trouble.
Keep the end carriage at a right angle to the girder.
Minimize any discrepancy in angling between the left and right end carriage frames (X and Y
dimensions).
WARNING : When installing the hoist and trolley on the girder, refer to the “Safety
Instructions” for your hoist and trolley respectively provided.
<Overhead type crane>
(a) Generally, the simple way to erect the completed crane is shown in Fig. 3. Lift crane into position
of following figure, then turn the crane so as to fit on the travel rails.
Fig. 3
(b) Precautions in installation (Refer to Fig. 4).
The end carriage comes set at a right angle to the girder and squared to size when delivered,
nevertheless, pay attention to the following points when coupling the end carriage to the girder on-
site.

Fig. 4
Minimize any discrepancy between the left and right end carriage frames position (D should be
minimized).
WARNING : If improperly assembled and installed, the crane will repeatedly strike the
stopper on the travel rail. This may cause bolts to loosen or other trouble.
Keep the end carriage at a right angle to the girder.
Minimize any discrepancy in angling between the left and right end carriage frames (X and Y
dimensions).
When using a urethane wheel crane, please lay a dedicated earth wire. When using an earth brush,
do not paint on the running surface of the track wheel. (Painting can also cause the track wheel to
slip)
WARNING : When installing the hoist and trolley on the girder, refer to the “Safety
Instructions” for your hoist and trolley respectively provided.
<Double girder crane>
Many double girder cranes come equipped with peripheral equipment and accessories, and there are
equally as many different ways to erect them.
(a) If the crane can be erected with the left and right end carriage frames attached to the girder, then
erect the crane according to the same procedure described for overhead cranes, check dimensions
after erecting the equipment, and adjust where necessary.
(b) If the crane cannot be erected with the left and right end carriage frames attached to the girder, then
first erect the end carriage frames on the travel rails as shown in Fig. 5. Next, turn the girders so as
to fit between the travel rails and lift into position, and attach the girders to the end carriage frames
on the travel rail.When assembling, set the end carriages to a right angle with the girder and square
with one another, and adjust span as necessary. (Refer to Fig.5)

(c) Precautions in installation (Refer to Fig. 6).
Pay attention to the following points when coupling the end carriage to the girder on-site.
Fig. 6
Minimize any discrepancy between the left and right end carriage frames position (D should be
minimized). If improperly assembled and installed, the crane will repeatedly strike the stopper on
the travel rail. This may cause bolts to loosen or other trouble.
Minimize any discrepancy in rail gauge between the traverse rails (RG1 and RG2 dimensions9.
Keep the end carriage frames parallel (Aand B should be the same).
5.2 Wiring
DANGER : ALWAYS turn OFF power source or breaker switch to prevent electric shock
before beginning the wiring process.
HAVE all wiring performed by an authorized electrician.
Power can be supplied by the cable power supply, tro-reel, or trolley duct systems. For wiring from the
power source to the crane’s control box, refer to “9. Power supply” in this manual.
5.2.1 Control box internal wiring
Control box wiring differs depending on whether the emergency stop device (option) to the push
button switch is attached or not, and whether an electric chain hoist or rope hoist is used. Check
wiring diagrams before wiring.
For your reference, typical wiring schemes are shown in Figs. 7 through 12.
