To carry out the work, our company purchased a SEM 919 motor grader and a SEM 816D bulldozer. This was reported to us by the head of the transport department, Gennady Alaniya: “Two more representatives of “SEM” in our fleet!

The SEM 919 motor grader is designed specifically for performing a large amount of earthmoving work. The high strength of the machine components allows the effective use of the 919 model in difficult road conditions. Engine: The powerful Shanghai D9 diesel engine with a working volume of 8.8 liters is characterized by high efficiency and reduced exhaust gas toxicity. Motor graders of this model are capable of developing power up to 190 hp, and the improved efficient engine cooling system allows the machine to be operated in the ambient temperature range from -40 ° to +50 °. Hydraulic system: The motor grader is equipped with a powerful hydraulic system that ensures the effective operation of standard and additional hydraulic equipment. Load-sensitive hydraulic system allows for maximum efficiency in engine power consumption. Components manufactured at CAT plants ensure smooth and efficient operation of the hydraulic system. Transmission: A nine-speed transmission (6F/3R) installed on motor graders allows for a maximum speed of 40 km/h. An improved design with an intermediate shaft provides gear shifting under load, which preserves useful engine power in the most difficult operating modes.

Operator’s cab: The SEM 919 motor grader is equipped with a comfortable operator’s cab located on the front frame, which provides the most optimal overview of the working area. The electro-hydraulic drive of the controls makes work with the best blade in its class.Axles and braking system: A three-section axle installed on a motor grader is equipped with a limited slip differential and ensures reliable and durable operation of the machine. The unique design of the front axle made it possible to implement optimal wheel inclination angles. A reliable brake system with a pneumatic-hydraulic drive provides effective braking in any conditions.

The SEM 816D bulldozer is a universal machine designed to perform a wide range of earthmoving operations. Equipped with a powerful engine and a hydrostatic drive with stepless speed regulation, the bulldozer of this model demonstrates high productivity and unsurpassed maneuverability. The low cost, which Chinese special equipment is traditionally famous for, in the SEM 816 D model is combined with excellent technical and operational characteristics and trouble-free operation of the machine in the most difficult conditions. Thanks to the implemented Caterpillar quality control system and the use of components from well-known manufacturers, bulldozers of this model demonstrate a long service life and do not require high costs for operation and maintenance.
