Caterpillar has replaced its D9T model dozer with the new Cat D9, which the OEM said can lower overall costs per unit of material moved by up to 3%.

The new dozer, which features a Cat C18 engine and a range of exhaust aftertreatment solutions available – including configurations to meet U.S. EPA Tier 4 Final/EU Stage V regulations and configurations equivalent to U.S. EPA Tier 2 and Tier 3 – is available with customised configurations to meet a customer’s needs.

Cat also said the machine has gained efficiencies, such as a new torque converter with stator clutch that reduces fuel consumption by as much as 5%, and a reduction in maintenance and repair costs of up to 4%.

The D9 has differential steering for a tight turning radius, along with the ability to maintain ground speed while turning to keep productivity high. Its suspended undercarriage delivers more track contact with the ground, offering less slippage and greater productivity. 

The OEM said the D9 can be equipped with a wide range of blades and attachments, giving it the ability to efficiently work in various applications including production dozing, site maintenance, fleet support and ripping. 

The dozer’s technology features include integrated sensors to provide access to advanced operating technology, the first of which is the Standard Product Link Elite and Vital Information Management System (VIMS) – powerful machine management tools that provide crucial dozer information like location, operating hours, machine condition and production information. 

It also has an available Automated Blade Assist, which uses preset blade pitch positions for load, carry and spread tasks, thus giving it increased efficiency and with reduced operator workload. The Cat AutoCarrysystem, also an option, automates its blade lift to maintain desired blade load to improve load consistency while reducing track slippage and increasing productivity. 

The optional Automatic Ripper Control helps maintain ripper depth and also limit track slip. 

The D9 will be available in the fourth quarter of 2020.
