SANY digger SY135C adopts the engine customized for SANY. This engine provides strong operating power and ensures high reliability and stability of the digger as a whole. The engine customized for SANY gives high efficiency, low fuel consumption and high reliability while fully guaranteeing the digger’s stability in continuous operation under severe weather conditions and satisfying customers for requirement of engine stability.The engine power of SANY digger SY135C is 72.7kw, and the displacement is increased to 4.329L, which reduces the engine heat load and gives a longer service life.
The principal parts and components, such as the main pump customized for SANY digger, the main valve, swing unit, travel unit, pilot control valve, are of excellent performance. The tri-grouser track shoe rolled with high-strength alloy provides favorable contact, stability and durability. The track links have additional reinforced ribs to increase their strength, which can absorb the shock when the digger travels on rough surface.
SANY SY135C’s reinforced X-frame modeled is with digital tools, through finite element analysis on loading capacity, realizes high-strength structure. And reinforced plates, welded on the two main beam of swing platform, considerably improve the bending resistance performance. The track links have additional reinforced ribs to increase their strength, which can absorb the shock when the digger travels on rough surface. The tension adjusting device is more reliable due to the adoption of a serially-arranged system that includes a grease-in tensioning cylinder and a damper spring.
