Cat 834 wheel dozer has a 496-horsepower Cat C18 engine available in Tier 4-Final, Tier 3 or Tier 2 versions. Blade choices include straight, universal, and coal with capacities from 10.3 to 29 cubic yards. The Cat 4F/3R planetary power-shift transmission has a new Advanced Productivity Electronic Control Shifting system, which is designed to provide greater machine momentum through shift points. The impeller clutch torque converter (ICTC) allows the operator to adjust rimpull from 100 to 25 percent in order to match hydraulic effort and rimpull to the operating situation. A completely redesigned operator station has automatic temperature control, new touch-screen display with soft keypad, electro/hydraulic parking brake, and the Cat Comfort III seat with air-ride suspension and integral controls—including the Steering Transmission Integrated Control (STIC) that allows convenient joystick steering. Interior sound levels are reduced to 71 dB(A), Caterpillar says. Cat Vital Information Management System has data-logging capability, and features an Ethernet connection module and an integrated Cat Product Link telematics system, which transmits data to a secure web-based application (VisionLink).
Redesigned with a Cat C18 ACERT Tier 4-Final diesel, Cat D9T dozer has 436 horsepower at 1,800 rpm.
The Cat MH3037 is the third model in a new wheeled-material-handler range that Caterpillar is introducing in the greater-than-25-ton size class.
