EquipmentWorld.com | June 2014 15 M eet the latest emissions standards while boosting productivity with Caterpillar's D9T dozer, which features a Tier 4 Final Cat C18 ACERT engine that de- livers 436 net horsepower at 1,800 rpm. With a high torque rise of 36 percent, the dozer is able to tackle the toughest material. The D9T carries over durable features from its predecessor, including a mainframe with cast steel main case, a pivot shaft that transfers blade loads directly to the mainframe, a modular drive train with three-speed powershift transmission and dif- ferential steering system, a heavy-duty undercarriage with track roller frames and bogie suspended rollers. Design enhancements to the D9T include an aluminum bar- plate radiator that offers improved cooling effi ciency as well as increased corrosion resistance. A new air-to-air aftercooler increases combustion effi ciency and fuel economy, and a new air-to-oil hydraulic cooler modulates temperatures to lengthen component life. An Advanced Productivity Electronic Control System improves transmission shifting performance. The APECS works with the Enhanced Auto-Shift system that automatically selects the optimum gear and engine speed match based on the machine's load and ground speed. Blade control technology includes Automated Blade Assist, which allows the operator to select pre-set blade positions, and Autocarry, which automates blade lift during carry seg- ments longer than 100 feet to minimize track slip. The Adap- tive Load Auto Select system adjusts the blade load based on soil type, moisture content and track performance. The D9T has a blade capacity of 17.7 cubic yards (semi-universal) or 21.4 cubic yards (universal). Operator environment enhancements include a multi-color touchscreen information display, seat belt reminder and sound suppression packages. EDITOR'S PICK EDITOR'S PICK SAFE LIFTING SYSTEM Boost effi ciency and safety during horizontal and directional drilling applications with Vacuworx's HDD Pipe Handling System, which uses wireless remote controller operation to tilt and place drill stems at angles between 0 and 30 de- grees without the use of ropes or slings. Designed for use with MC Series lifters, the lightweight unit requires just one worker to lift the drill stem and transfer the pipe into a drilling rig. A 360-degree hydraulic rotator gives operators complete control over the drill stem and enables precise pipe joint placement. Able to handle single joints of steel pipe from 3 to 18 inches in diameter, the system has lift capacities ranging from 1,700 to 5,400 pounds, and is well suited for smaller excavators, forklifts, cranes, wheel loaders and boom trucks. An integrated safety control valve ensures pipe is never dropped. marketplace | by Amy Materson | AMaterson@randallreilly.com DOZER TACKLES TOUGH MATERIAL
