The expansion of our Komatsu product line into the 1/64 scale size was announced last year, but now we would like to take a closer look at our 1/64 scale Komatsu D155AX-8 SIGMADOZER with Ripper!

The SAA6D140E-7 engine found in the D155AX-8 dozer is EPA Tier 4 emissions certified and provides exceptional performance while reducing fuel consumption. Through the in-house development and production of engines, electronics and other component parts, Komatsu has achieved pronounced advancements in technology, providing high levels of performance and efficiency in nearly all applications.

The D155AX-8 dozer features the innovative SIGMADOZER, which offers both a high level of productivity and fuel economy through the usage of the blade and the automatic transmission with lockup torque converter. The frontal design concept adopted for digging and rolling up at the center of the blade increases soil holding capacity, while also reducing sideway spillage and reduced digging resistance produces smoother flow requiring less power.

The operator's cab of the D155AX-8 dozer features the integrated ROPS cab with large glass windows for outstanding visibility. The standard air-suspension seat positions the operator comfortably and the high rigidity and superb sealing around the cab greatly reduces the noise and vibration for the operator, and also prevents dust from entering the cab. The dozer's cab mount uses a cab damper to provide excellent shock and vibration absorption. The cab damper softens the shock while traveling over adverse conditions, and the cab damper spring isolates the cab from the machine body, therefore suppressing vibrations and providing a quiet, comfortable operating environment.

The standard Rear View Monitoring System allows the operator to view the rear of the machine on a color monitor screen, the the visibility of the ripper during operation is easily seen. While on the ripper, the new single-shank ripper has been expanded to offer a wider range of operation over that found on previous versions.

The K-Bogie undercarriage system offers many advantages including minimal track slippage for improved traction, reduced impact leading to more durable components and improved operator comfort.

With the features of the life-size model in mind, let's take a look at the details of our new 1/64 scale diecast metal replica. This new model features the SIGMADOZER blade that moves up and down, the accurately detailed ROPS operator cab, working segmented metal tracks that are constructed from individual diecast metal links, and a single-shank ripper that moves up and down. The authentically detailed replica measures 5.25"L x 2.5"W x 2.125"H and will be ready to add to your collection soon!
