The Shangong Machinery SEM816 crawler dozer is designed for the needs of Chinese users, providing customers with higher production efficiency, lower fuel consumption and an easy and comfortable operating system. The world-class brand of powertrain and control system escorts the reliability, economy and comfort of the machine. Shangong Machinery SEM816 crawler bulldozer evaluation The SEM816 bulldozer inherits Caterpillar's advanced technology, parts are manufactured by internationally renowned brands, reliable quality, and have been comprehensively improved in terms of operating efficiency, fuel consumption, intelligence, maintenance and operation. High efficiency and energy saving: The hydrostatic technology of Caterpillar bulldozers is 10%-30% higher than the same year-on-year. Weichai three-stage electronically controlled engine provides heavy duty/standard/economic three working modes, which can be freely selected according to working conditions. . Multi-function electronically controlled walking handle for in-situ steering, power steering and cruise control; easy to operate and precise control of operation. The SEM816 bulldozer designed specifically for emerging markets uses the latest hydrostatic drive technology. It is equipped with a world-class powertrain and control system to further ensure the reliability and durability of the machine. The hydrostatic drive, load feedback drive train automatically adjusts speed and power to match varying loads; each side track is independently powered by a combined variable displacement piston pump and motor. Outstanding technology with world-class core components gives customers a more productive and efficient machine. Automatic dual-circuit electronically controlled hydrostatic drive enables the machine to achieve infinitely variable speed, fast acceleration and commutation, and precise steering control. The power steering improves the maneuverability of the machine under soft conditions. The in-situ steering provides flexibility and maneuverability of the machine in a small blockage site, which extends the machine's operation in narrow and congested conditions and improves Work efficiency. The L-shaped push arm brings the blade closer to the machine, providing the machine with superior maneuverability, balance and blade penetration. The semi-U-type pusher and straight shovel have a powerful box structure that allows the machine to work under heavy-duty mining. The standard tractor frame, optional multi-tooth ripper and low ground-ratio pressure track provide a rich working device for the SEM816 to handle any dozing conditions. The industry's unique L-shaped push arm makes the thrust more stable. Equipped with a SU-type shovel for both large capacity and good leveling! Caterpillar is designed for four-wheeled belts. The guide wheels and drag chain wheels are maintenance-free for life, and the thickness of the spurs and track shoes is 10% larger. Good cooling capacity, up to 50 °C ambient operating temperature requirements. Maximize operator comfort Considering the long-term operation of the operator, the design of the SEM816 greatly improves the comfort of the operator. The bulldozer combines the direction and steering controls, including the speed adjustment handwheel, into a single handle, while providing a ground speed setting button. This results in unparalleled control, maneuverability and productivity (fast steering, in-situ steering and forward and reverse direction shifting), reducing operator fatigue. The spacious cab is also equipped with a pilot control of the working hydraulic system. Pilot control ensures that the SEM816 achieves a fast response with less control power. Provides easier and more comfortable handling for the operator while improving machine maneuverability. The interior of the cab is also designed to reduce operator fatigue and improve comfort. Commonly used switches are placed at the touch of the operator's hands. The console is more readable. The design of the armrests enhances comfort. The integrated deceleration and brake pedal reduces operator fatigue. The cab has a wide field of view and is equipped with a multi-function suspension seat for easy operation and improved work efficiency. The spacious cab is also equipped with a pilot control of the working hydraulic system. Pilot control ensures that the SEM816 achieves a fast response with less control power. With perfect armrests and handle settings, you can ensure three-point contact when getting on and off the car, fully ensuring safety! The engine uses Weichai's electronically controlled engine, which has strong power and more accurate emission control. With the rapid development of China's infrastructure construction, bulldozers have played a vital role in road construction, railway construction, airports, and water conservancy projects. The SEM816 crawler dozer designed and manufactured for domestic customers' applications and requirements can provide customers with comfortable operation, high productivity and low fuel consumption. In order to ensure the quality of the products, Caterpillar has been focusing on 6 Sigma, lean production and other methods and standards throughout the process of new product development, raw material selection and production process.
