User manual SMART DEVICES TA2050

[. . . ] Cushion Hitch The cushion hitch is a Caterpillar proven system for protecting components of the hitch and improving ride quality, dampening loads that might otherwise be carried through the frame to the operator. Cushion hitch offers operators a more comfortable haul portion of the work cycle. Durability Cat wheel tractor-scrapers have a history of robust structural design, tested and validated to last in the most rugged loading and hauling conditions. 19 2 Quick loading, high travel speeds and the ability to load and dump on the run yield fast cycle times, allowing Cat Wheel Tractor-Scrapers to consistently deliver high productivity at the lowest cost per ton. [. . . ] ⷠTransmission Hold maintains converter drive for maximum rimpull or holds current gear for best control. Neutral Coast Inhibitor prevents transmission shifts into neutral while moving. smooth Transmission Gear Shifting The TA2050 features ECPC Shift Torque Management (STM) , with improved Shift Control Logic (SCL) and Part Throttle Shifting (PTS). These features allow smoother shifting and greater acceleration on grades while torque is maintained through the shift changes. SCL also provides automatic shift selection that is more specific to the desired machine operation, and downshifts when needed for maximum acceleration when increased throttle is applied. PTS allows shifting at lower speeds during part throttle operation, resulting in improved part throttle fuel economy, quieter machine operation, and better maneuvering in reduced speed operating conditions. brake Performance The TA2050 uses hydraulically-actuated wet disc brakes for exceptional brake performance. The standard Cat Engine Brake reduces brake wear and enhances machine control. 6 3 2 5 7 8 6 4 4 8 1 Structures Cushion Hitch Superior design and construction delivers long term durability. Electronically actuated with parallelogram-type linkage for exceptional strength, with two nitrogen accumulators (4) using free-floating pistons (8) to deliver a smooth ride for enhanced operator comfort and machine durability. Leveling valve (7) applies pressure via an orifice (5) to automatically center the piston in load cylinder (1) · Steel castings are used to eliminate many welded joints and increase strength · Double-kingbolt design (2, 3) withstands high external forces, simplifies installation and removal Lockout Switch An operator-selectable lockout switch, located on the joystick, locks the cushion hitch down for improved control of the cutting edge during loading and dumping. The push-pull arrangement features a hydraulically-actuated bail and cushioned plate, which are bolted to the front of the tractor, and a hook that is attached to the rear of the scraper. Working together, push-pull scrapers can provide the lowest cost per meter (yard) for many applications. 9 Integrated Technologies Sequence Assist Technology options to improve operator comfort and increase productivity. Sequence Assist uses integrated software and position-sensing cylinders to automate many of the tasks an operator performs when loading, hauling and dumping. The operator simply sets preferences for bowl and apron height and subsequently pushes a button to ready the machine for loading, then hauling, then dumping, and then the return to cut. The system automatically sets the cushion hitch, bowl height, apron and ejector. Sequence Assist comes with a convenient load counter for tracking material moved. With Sequence Assist, up to 14 individual implement and machine commands are replaced by four touches of a button, allowing the operator additional time to prepare for the loading cycle and observation of the job site. Load Assist Load Assist builds on Sequence Assist by loading the bowl with the push of a button. As the machine enters the cut, the operator can activate Load Assist so the system takes over control of the cutting edge height, limiting tire spin based on integrated sensors and GPS technology to ensure consistent and full bowl loads. The operator is responsible only for the throttle, steering, and operating the apron. [. . . ] The ladder provides a rigid and angled base of support for easier climbing and descent. For added safety, the steps are illuminated by LED lights. An actuator under the cab operates the step. When not in use, the ladder retracts under the cab. [. . . ]
