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. [. . . ] 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. 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. [. . . ] Caterpillar has been and 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. A secondary engine shutoff switch is located at ground level. Integral to the cab and frame, the ROPS is resiliently mounted to the frame to isolate the operator from vibration for a more comfortable ride. [. . . ]
