User manual CATERPILLAR MD6290 BROCHURE

[. . . ] Extra leg room, easy-to-reach long-life rocker switches and revolutionary joystick controls make this the most comfortable cab in the industry. Standard HVAC system The high capacity system dehumidifies and pressurizes the cab, circulates fresh air, seals out dust and keeps windows clear. Low Interior Sound and Vibration Levels Multiple isolation mounts along with relocated hydraulic pump and valves significantly improve operator comfort and productivity. In-Dash Instrument Cluster Easy-to-read, high-visibility gauges and warning lamps keep the operator aware of critical system information. 3 Steering and Implement Controls Unprecedented precision and ease of operation. Ease of Operation Two electro-hydraulic joysticks require up to 78% less hand and wrist movement than conventional lever controls for greatly enhanced operator comfort and efficiency. The intuitive control pattern allows both new and experienced operators to quickly become productive. Electronically adjustable control pods help position joysticks for optimal comfort, visibility and proper operation. Joystick Functions · The left joystick primarily controls the machine direction and speed including steering, articulation, return-to-center, wheel lean, gear selection, left moldboard lift cylinder and float. The right joystick primarily controls drawbar, circle and moldboard functions including right moldboard lift cylinder and float, moldboard slide and tip, circle turn, drawbar center shift, electronic throttle control and manual differential lock/unlock. · Intuitive Steering Control Joystick lean angle mirrors the steer tires' turning angle. [. . . ] Controlled Throttle Shifting helps to smooth directional and gear changes without using the inching pedal. Load Compensation ensures consistent shift quality regardless of blade or machine load. This standard feature automatically shifts the transmission at optimal points so the operator can focus on the work to help improve safety, productivity and ease of operation. Power Shift Countershaft Transmission and the Cat C9. 3 engine maximize power to the ground. Eight forward/six reverse gears optimize productivity. Engine Over-Speed Protection prevents downshifting until an acceptable safe travel speed has been established. · · · · · Bolt-On Modular Rear Axle Improves serviceability and contamination control with easy access to differential components. Hydraulic Brakes Hydraulically actuated, oil bathed, multi-disc service brakes at each tandem wheel (1) offer the industry's largest total brake surface area (2) for dependable stopping power and long brake life. The brake wear indicator/compensator system (3) maintains brake performance and indicates brake wear without disassembly, for fast servicing and longer brake service life. The spring-applied, hydraulically released multidisc parking brake, sealed and oil-cooled for long life and low service, is integrated into the Operator Presence System to prevent unintended machine movement. 6 Structures and DCM Service ease and precise blade control. Heavy Duty Durability The frame, drawbar and one-piece forged steel circle are designed for durability in heavy duty applications. The strong A-frame drawbar uses a durable tubular design. The front 240° of circle teeth are hardened to reduce wear and ensure component reliability. Articulation Hitch A large tapered roller bearing at the lower pivot carries loads evenly and smoothly. Sealed to prevent contamination, a locking pin prevents articulation for safety during service or transport. Aggressive Blade Angle Allows material to roll more freely along the blade, particularly dry materials or cohesive soils. Please consult your Cat dealer for availability. 10 Work Tools and Attachments Equip your machine for the job. Moldboard Options Standard 3. 7 m (12 ft) or optional 4. 3 m (14 ft). Left and right side extensions are also available. Ground Engaging Tools (GET) A variety of tools are available from Cat Work Tools, including cutting edges, graderbits and end bits, all designed for maximum service life and productivity. Front Mounted Groups A front mounted push plate/counterweight or front lift group are available. The front lift group can be combined with a front dozer blade or front scarifier for added versatility. Rear Ripper/Scarifier Made to penetrate tough material fast and rip thoroughly for easier movement with the moldboard. The ripper includes three shanks (with holders for five). Nine scarifier shanks can also be added for additional versatility. Snow Removal Work Tools Multiple snow plow, snow wing and mounting options increase machine versatility and utilization throughout the year. 11 Safety Protect your most valuable resource. Designed with Protection in Mind Features are designed to enhance operator and job site safety, such as drop-down rear lights and a rearview camera. Among many standard safety features are laminated glass, back-up lights, and perforated tandem walkways and grab rails. Operator Presence System The parking brake remains engaged and hydraulic implements disabled until the operator is initially seated and the machine is ready for operation. Secondary Steering System Automatically engages an electric hydraulic pump in case of a drop in steering pressure, allowing the operator to steer the machine to a stop. Hydraulic Lockout A simple switch located in the cab disables all implement functions while still providing machine steering control. This safety feature is especially useful while roading. Brake Systems Brakes are located at each tandem wheel to eliminate braking loads on the power train. Redundant brake systems utilize accumulators to enable stopping in case of machine failure, further increasing operational safety. Circle Drive Slip Clutch This standard feature protects the drawbar, circle and moldboard from shock loads when the blade encounters an immovable object. It also reduces the possibility of abrupt directional changes in poor traction conditions. Blade Lift Accumulators (Optional) This optional feature uses accumulators to help absorb impact loads to the moldboard by allowing vertical blade travel. Blade lift accumulators help reduce unnecessary wear and also help reduce impact loading for enhanced operator safety. Rearview Camera (Optional) Visibility is further enhanced with an optional Work Area Vision System (WAVS) through a 178 mm (7 in) LCD color monitor in the cab. Developed specifically for rugged applications, this durable camera improves productivity and increases operator awareness of surroundings. Front and Rear Fenders (Optional) To help reduce objects flying from the tires, as well as build-up of mud, snow and debris, optional fenders can be added. 12 Customer Support Unparalleled worldwide support. Renowned dealer service From helping you choose the right machine to financing and ongoing support, your Cat dealer provides the best in sales and service.
