Rough Terrain Cranes "Reverse Steering System"

January 11, 2005

In relation to our Home Page "Announcement" dated on December 17th, 2004, we would kindly ask Tadano Rough Terrain Cranes customers of the following Model and Serial No. to contact us for the betterment arrangement and safety crane operation.

Part of Malfunction;
Reverse steering system

State of Malfunction;
This reverse steering system is developed to help secure work efficiency on jobsites with the operator's seat turned in the rear direction of the crane. The reverse steering switch should therefore be turned "OFF" after completion of the reverse steering work on jobsites. The switch, however, was left in "ON" position for some reason or other. In such conditions, the crane, if steered, may turn in the opposite directions of the steering direction in case the boom rear-position detection switch fails.

Safe Crane Operation;
Be sure to RELEASE the REVERSE STEERING SWITCH "OFF" after completion of the reverse steering operation. No malfunction will ever occur provided the reverse steering switch is placed in "OFF" position.

Betterment Measures;
(A) In those cases where customers do not or seldom use the reverse steering systems for their jobsite operations, we can invalidate the system itself by removing the reverse steering switch.

(B) In other cases than (A) above, to prevent any misoperation of the reverse steering system (failure to turn "OFF" the switch), we have made modifications to the system circuit so that operation of the system concerned can be automatically disabled when traveling with the reverse steering switch left activated to keep the crane from falling into a reverse steering state even in case of the occurrence of a system failure of the boom rear-position detection switch, and further that an alarm buzzer can sound to warn the operator of the reverse steering switch being left to the ON position. The system of all the applicable models will be replaced with new one.
In view of the time required for technical verification and parts supply in this relation, first we take the following measures and the new system will be provided as soon as possible after completion of the technical verification. To prevent misoperation of the system, we make the instructions for use known to every user.

Applicable model and serial number are as follows;
