User manual CATERPILLAR D11T BROCHURE

[. . . ] MEUI combines the technical advancement of an electronic control system with the simplicity of direct mechanically controlled unit fuel injection. The MEUI system excels in its ability to control injection pressure over the entire engine operating speed range. These features allow the C32 to have complete control over injection timing, duration, and pressure. Air-to-Air Aftercooling Provides cooled compressed air to the engine intake manifold; reducing emissions and maximizing fuel efficiency. Overhead Cams Two, single (one per head) overhead cams are driven by gears on the flywheel end of the engine. Placing the cam gears at the flywheel end significantly reduces noise and vibration. [. . . ] The brakes are applied by springs and hydraulically released for safe and reliable braking performance.

The 3-speed forward, 3-speed reverse transmission offers excellent runout speeds. 1 Elevated Final Drives Isolated from ground and equipment induced impact loads for extended power train life. Crown-shaved drive gears provide smooth, quiet, low maintenance operation. Splash lubrication and Duo-ConeTM Seals extend service life. 2 3 0 0 1 2 2 4 3 6 4 8 5 10 6 7 12 km/h mph Modular Power Train The design permits quick removal and installation of major components such as the engine, transmission and final drives.

Mainframe Strength The D11T and D11T CD mainframes are built to absorb high impact shock loads and twisting forces of severe dozing and ripping. The two frames share the following features: Frame Rails Full box section design keeps components rigidly aligned. Heavy Steel Castings Strengthen the main case, equalizer bar saddle, front cross member and tag-link trunnion. Top and Bottom Rails Made from continuous rolled sections to eliminate welds and machining, which provide superior mainframe durability. Main Case Elevates the final drives well above the ground level work area to protect them from impact loads, abrasion and contaminants. Oil reservoir included in one-piece cast casting. Pivot Shaft The pivot shaft and pinned equalizer bar maintain track roller frame alignment. Heavy Cast Saddle Ribbed design increases frame life. Engine and Radiator Guard Mount The common front engine and radiator mount feature heavy castings. CarryDozer Frame The CarryDozer frame is specifically designed for carrying material long distances. The taller front end accepts additional frame loads generated by the unique CarryDozer blade design. Tag-Link Reduces wear and brings the blade closer to the machine for more precise dozing and load control. Dual Tilt ­ Improves load control and allows the operator to optimize blade pitch angle. Cutting Edges and End Bits ­ Cutting edges are made of DH-2 steel. Abrasion Versions ­ These versions of the "SU" blade and "U" blade extend blade life. Abrasion blades come with rock guards, wear plates and extended wear life cutting edges and end bits. Multi-Shank Ripper ­ Tailors the tractor to the material by using one, two or three shanks. Single-Shank Ripper ­ Operator can adjust the shank depth from the seat using an optional single-shank pin puller. Large one-piece shank is available in deep ripping configuration. · · · · · · Rippers Hydraulic Pitch Adjustment Cylinders Hydraulic pitch adjustment cylinders vary the shank angle to get the best penetration. Rear Counterweights Provide proper tractor balance to maximize dozing production. Recommended if not equipped with any other rear attachment. 10 Safety Product Safety Cat mining machines and systems are designed with safety first. Caterpillar continues to be proactive in developing mining machines that meet or exceed safety standards. Safety is an integral part of all machine and systems designs. ROPS and FOPS The structure is designed to carry loads directly into the tractor main frame and protect the operator. Access/Egress An attachment rear walkway equipped with grab irons and steps, provides access to rear lights, rear and side windows. A hydraulically actuated access ladder is available, for easier machine access and egress. Visibility An attachment visibility arrangement including WAVS rear vision cameras are available. Electrical System Lockout/Tagout A disconnect switch is available to shut off all machine electrical power. Another disconnect switch shuts off the ability to engage the starter, while keeping main power available for diagnostics and troubleshooting. Lighting Standard HID lighting provides superior illumination around the machine for night operations. The 35 watt HID lamps provide lighting equivalent to 4 Halogen lamps, without producing significant glare. Two underhood service lamps illuminate the engine compartment for easy night service. The fender lights will stay on for a 10 minute period after key off to allow the operator to safely egress the machine at night. SAFETY. CAT.
