Reduction of starting & stopping shock.      

The swing of load and building is reduced by the smooth inverter performance which restrains the shock of starting and stopping.


Settable traveling speed for efficient operation      

The optimal operation speed (High and Low speed) can be set in the range from 1/10 to standard speed.

Inching and plugging operations are possible.


Small body and easy installation.   TIB is equipped with a regenerative resistor unit as a standard equipment, and it can be installed directly to a crane girder with ease.



Improved ease of maintenance

In case a defect occurs, the function that displays failure mode facilitates the judgment of locating fault.

The main circuit (noncontact) enhances reliability and improves ease of maintenance.


Enhanced safety functions   

In addition to the conventional functions (over load, the protection of regenerative over voltage), the function of detecting input circuit fault is equipped as a standard.


Shared protection board function (TIB-S)      

Circuit breaker box and contactors for on and off (electric power supply) are standard equipment.

The box can combine with shared protection board for crane.

Screw holes are provided for the contactors of light, buzzer and etc.

Top-Running Crane Saddle and Suspension Crane Saddle are available.
