Komatsu Introduces New Power Shift Backhoe Loaders

Komatsu Utility Corporation continues to expand its line of products with two new backhoe loaders: the WB14OPS-2 and the WB15OPS-2. These two models feature Komatsu's new power shift transmission, Electronic Gear Management (EGM) and anti-theft mode for greater performance and versatility.

The new power shift transmission is electronically controlled with four forward and three reverse gears, and can reach a top speed of 25 mph. The operator can switch driving direction and gears during operation without power interruption or disengaging the machine.

"These new backhoe loaders are ideal for digging or loading applications when the front loader or long distance travel require continual gear changes," says Hank Yasuhara, Komatsu director of product marketing.

When the operation, condition or individual needs change, the operator can customize the gear selection to either automatic or manual mode by using two buttons near the steering wheel. Another button (kick down), located on the handle of the loader control 1st and 2nd lever, allows and gear to be selected without using the gear controls.

The EGM controls are positioned on the left of the steering wheel and have been designed to allow the operator to perform all functions without having to take his hands off the wheel. The special microprocessor fitted in the EGM not only manages the commands sent to the transmission, but also offers other important functions such as; system self-diagnostics, automatic connection/disconnection of the 4-wheel drive and activation of the anti-theft alarm using a PIN code.

Finally, the power and efficiency of the power shift transmission is increased by the use of heavy-duty type axles with planetary hub reductions and electrohydraulically operated differential lock. Maximum operator safety is achieved by the superior braking system and the oil immersed multidisc brakes can be independently operated by utilizing either foot pedal.
