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).
The Cat 336F H Hybrid hydraulic excavator will soon be powered by a Tier 4-Final Cat C9.3 ACERT engine rated at 303 horsepower.
The new Cat 966M, 966M XE, 972M, and 972M XE wheel loaders meet Tier 4-Final emissions regulations with a combination of combustion strategies and after-treatment components.
