Power Train ­ Engine The Cat C11 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. [. . . ] 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. 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. Sealed colleted pins are fitted to all bucket and lift arm hinge points for longer pin and bushing life. This reduces maintenance costs and extends service intervals. The sealed joints retain lubrication and prevent contaminant entry. Hitch. Spread hitch design widens the distance between upper and lower hitch plates to distribute forces and increase bearing life. The wide opening provides easy service access. Upper and lower hitch pins pivot on roller bearings to distribute horizontal and vertical loads over a greater surface area. Shim adjusted preload reduces maintenance time. An on-board steering frame lock pin is fitted to prevent articulation during maintenance and service. 7 Operator Station Setting a new industry standard for comfort and efficiency. Ergonomic Layout. The operator station is ergonomically designed for total machine control in a comfortable, productive and safe environment. [. . . ] A secondary engine shutoff switch is located at ground level. The operator station has integrated into its construction a ROPS ­ Roll-over protective structure and FOPS ­ Falling object protective structure. This structure is resiliently mounted to the frame, reducing vibration to the operator for a more comfortable ride. Four corner oil-cooled braking system provides excellent control. [. . . ]
