Power Train ­ Engine The Cat C15 engine with ACERTTM Technology delivers the power and reliability necessary to perform in the most demanding underground mining applications. Designed for efficient operation, excellent fuel efficiency, lower emissions, reduced engine noise and lower operating costs. 4 ® Power Train ­ Transmission The Cat four-speed planetary power shift transmission features heavy duty components to handle the toughest jobs. [. . . ] Hydraulic actuated independent circuits provide improved performance and reliability. Cat ET service tool provides service technicians with easy access to stored diagnostic data through the Cat Data Link to simplify problem diagnosis and increase availability. 5 Hydraulics Cat hydraulics deliver the power and control to keep material moving. Pilot Controls. Low effort, pilot operated joystick implement control with simultaneous lift and tilt functions optimizes operating efficiency. The optional ride control system uses a nitrogen filled oil accumulator in the hydraulic lift circuit to act as a shock absorber for the bucket and lift arms. The lift arm and bucket response to movement is dampened over rough ground, reducing fore and aft pitch, improving cycle times and load retention. A smoother, more comfortable ride gives operators the confidence to travel at speeds above 5 km/h (3 mph) during load and carry operations. Field proven Cat high pressure XTTM hydraulic hoses are exceptionally strong and flexible for maximum system reliability and long life in the most demanding conditions. Reusable couplings with O-ring face seals provide superior, leak free performance and prolong hose assembly life. Hydraulic System. Powerful Cat hydraulics deliver exceptional digging and lifting forces for fast cycle times. Lift and Tilt System. High hydraulic flow rates provide fast hydraulic cylinder response and powerful lift forces. Large-bore lift and tilt cylinder delivers exceptional strength, performance and durability. 6 Structures Designed for maximum strength and durability in the harshest operating environments. Frame Design. The frame features robust structural components for outstanding durability in the toughest loading conditions. Caterpillar integrates advanced processes in the design and manufacture of Cat frames and structures. Computer modeling and Finite Element Analysis (FEA) are used extensively throughout design. Strong steel frame structures are designed to resist twisting forces, torsional shock and stresses generated during the loading cycle while protecting drive line and hydraulic system components. Solid steel lift arms absorb high stresses generated during loading without sacrificing strength or durability. The linkage design offers excellent reach and dump clearance for better productivity. Lift arm support pins prevent lowering the lift arms during service and maintenance. The four plate loader tower provides a solid mount for lift arms, lift cylinders and Z-bar tilt lever. The loader frame is designed and built to absorb twisting, impact and high loading forces. The cast steel cross tube provides excellent resistance to torsion and impact loads, keeping pin bores aligned and extending component service life. Proven Z-Bar loader linkage geometry generates powerful breakout force and an increased rack back angle for better bucket loading and material retention. Sealed Pins.
