Click here and find out why SANY digger top performance

SANY digger adopts powerful customized engine that provides strong operating power and improves fuel efficiency for the machine. The engine is designed with four working modes, and the working mode can be changed on the monitor according to different job sites, which can maximize the operating efficiency and reduce the fuel consumption.

SANY digger’s electric control module has the capability of making quick response to the change of operating variables in order to achieve optimum engine performance. It is fully integrated with sensors of fuel, engine oil, air intake, coolant and exhaust system to conduct real-time monitoring and auto-adjustment on the system conditions, which can ensure the engine won’t overload when it works with full load.

With a dual-pump, dual-circuit constant power control system, the engine can fully develop its power to provide a strong operating force. Optimized operation performance of the engine reduces the loss of power.

Through digger’s electrical control, such as engine throttle position feedback, the engine speed monitoring, and power limit regulation, as well as the hydraulic control, such as main pump positive flow control, straight-trawl proportional control, swing-priority proportional control, and bucked confluence proportional control, the engine can have real time power match with hydraulic pumps, which improves operational productivity and reduces fuel consumption.

SANY digger equipped with advanced computer dynamic control system, which determines engine output power as per the extreme load demand, achieving the optimum control of digger-extreme load operation system.

SANY digger boom and arm use large-box structure, in which welded plates against torsion form a compact, strong and durable integrity that prevents deformation under larger digging force. With optimized deign, the boom and arm can provide considerable working range and depth on the occasion of ditching, excavating and common construction. In addition, standard reinforced bucket with highly rigid steel sheet, tips and side cutters can serve a longer period.
