lever, turn on the power of the transmitter. If the above does not restore the normal operation, the radio-control operation is impossible. Change to the manual operation and operate the crane.

30-33 After the operation lever that corresponds to the error number is manually

returned to the neutral position, check if the error number disappears. When the mode indicator lamp displays “L1” and when the error number does not reappear after operation is started, the operation can be continued. If the operation lever cannot be returned to the neutral position or if the error number does not disappear, the radio-control operation of the part that has a problem is not possible. Change to the manual operation and then operate the crane.

Measures for Emergency Case

2. If the Radio-control is not Possible

1. The unloading solenoid of the radio-control

valve should be fastened so that the crane can be manually stowed. (1) Remove the cap nut. (2) Loosen the lock nut and lightly tighten the screw inside until it cannot be turned any longer.  Fastening the screw too tight may cause

operation failures. Make sure to lightly tighten the screw.

2. After manually stowing the crane, have the

crane and radio-control system inspected/repaired at the nearest TADANO distributor or dealer.

This is a measure to stow the crane in an emergency case. Do not

make any crane operation.

Troubleshooting Guide

Radio wave transmission is hindered under the following conditions, which may stop the crane operation. Take an appropriate measure according to the operational condition.  If the appropriate measure does not improve the situation, use the manual operation.

Operation example

Appropriate measure

Distance between the transmitter and reception unit is too far.

・

Too large a distance between the transmitter and reception unit may not only hinder the radio wave transmission but also increase noise influences. Normally, make the operations within the

operating radius of the crane. Operation is made near the noise-generating source.

M00247

・When a noise generating device such as

a revolving light, electric fan or vehicle’s

air conditioner is used nearby, the

radio-control operation is influenced by

the source.

Turn off the noise-generating device

when it is possible to refrain from using it.

Since a motorcycle also generates a

noise, pay attention to motorcycles

passing through.

Operation is made in a place with an intensive radio wave interference causing noise to the radios and to television screens.

・Approach the transmitter to the reception

unit and operate the transmitter.

A large metal cargo is lifted with the crane. Or, there are obstacles between the transmitter and reception unit such as wire netting or metal doors.

M22678

?

・Metal products between the transmitter

and reception unit hinder the radio wave

transmission. Move yourself to the

location where the reception unit can be

seen and then operate the transmitter.

Daily Inspection

25

Daily Inspection

Inspect the radio-control system at the time of the pre-operational inspection of the main unit of the crane.

(1) Is the case of the transmi t ter o r cont ro l

unit damaged? Do switches or rubber parts of the transmit ter hav e any crack or flaw?

Any damage on the case or any crack or flaw on the rubber parts may allow water or dust to enter inside, causing electronic circuit problems or malfunction of the crane.

(2) Do the motion selection switches and

speed control lever move smoothly?

Adhered dust or dirt may give unfavorable impact on operations of the motion selection switches or speed control lever, causing operation failures or malfunctions of the crane.

(3) Is the fixing screw of the transmitter’s

battery cover securely tightened?

A loose fixing screw of the transmitter’s battery cover may allow water or dust to enter inside, causing electronic circuit problems or malfunction of the crane.

(4) Is the cable between the control unit

and communication unit loose or damaged? Is the antenna of the communication unit damaged or loose?

If the connector of the cable or antenna is loose, a radio wave reaching distance may be reduced or the radio-control system may be subject to noises.

In addition, if the cable or antenna is damaged, the radio-control system may be subject to noises.
