SBR-800 and SBR-1200 are mobile concrete mixers with a hydraulically-operated skip, with the capability of power loading of components into the skip and with the reverser for unloading. They can be used as separate mortar-concrete machinery as well as on production lines at precast concrete plants and concrete factories. At the customer's request this equipment is provided with the cement tank, the screw for cement unloading, the sand/ crushed stone-loading belt conveyor. Concrete mixers SBR-800A, SBR-1200A are equipped with an internal combustion diesel engine manufactured by German company "HATZ".

Characteristic features of the engine:

• Noise protection: acoustic radiation is minimized due to constructive measures and high accuracy of manufacturing,
• Universal widely applicable industrial engine,
• Low weight due to lightweight metal structure,
• Low fuel consumption due to direct injection by a multiple-jet nozzle,
• Resistance and durability,
• Low repair costs due to separate cylinders and cylinder heads,
• Particular safety due to the absence of V-belt,
• Simple operation,
• Automatic spraying pump air removal.

Engine structure:

• Air-cooled two-cylinder four-stroke engine,
• Vertical cylinder with direct injection,
