SY465C Sany excavator specs & Dimensions (2012 - 2026)

Secondary Boosting Technology

When the target load is heavy, a pressing of the boosting button on the left joystick can provide an explosive power (lasting 8 sec.) to boost bucket digging force by 10% instantaneously to complete additional work load.

The Reasons for Energy Saving and High Efficiency

With a dual-pump, dual-circuit constant power control system, the engine can fully develop its power. The perfect combination of this two realizes the heavy-duty mode with large workload, the standard-mode with auto-adjusted engine speed and light-duty mode, high efficiency and low fuel consumption, while optimizing the combustion.

Full-power Variables Main Pump

The main pump consists of two plunger-type pumps of serial variable displacement. The two pumps are controlled via full-power variables, meaning that the sum of power of two pumps is kept constant. When a single pump is running, this pump can absorb the power of the other idle hydraulic pump to ensure the full use of engine power.

The Electric Control Module to Achieve The Best Engine Efficiency

The 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 systems to conduct the real-time monitoring and auto adjustment on the system conditions, which can ensure the engine won’t overload when the excavator works with full load.

New Controller

A new controller is used to perform innovative electro-hydraulic control over the machine, the engine can have a real-time power match with hydraulic pumps, which improves operational productivity and reduces fuel consumption. An advanced control dynamic control system (CDCS) determines engine output power as per the external load demand, achieving the optimum control of excavator-external load operation system.

Working Mode Selection H, S, L and B Working Modes

Heavy duty mode: for soil and rock conditions, engine throttle is at the maximum allowing full-power output and the highest operating efficiency. Standard mode: for soil conditions, input power of main pump is about 90% of maximum engine power, reducing fuel consumption and noise. Light duty mode: for the ground and soft soil conditions, input power of main pump is about 80% of maximum engine power, with lower fuel consumption and high economy. Break mode: 90% of the rated power reduces fuel consumption. Four Working Modes Meet The Requirement of Efficient Large-workload Operation and Fuel Economy.

Arm Regeneration Circuit

A quick circuit is added to the arm oil cylinder circuit. When the arm oil cylinder is extended, the oil return circuit is cut off and hydraulic oil flows from the return circuit into the cylinder via a check valve. The hydraulic oil in the arm cylinder rod end does not return to the tank but goes directly to the cylinder head end. As a result, the arm speed is increased, and the fuel consumption is down by 10% under this condition.

Boom and Stick Holding System

The holding valve on the main control valve can prevent the boom and arm from declining under their own weight and extend holding time, improving reliability of the machine.

Anti-swing Valve and Delay Valve

Swing mechanism with anti-swing valve and delay valve makes swing operation more stable and reliable; swing brake ensures safety of machine stopping.

Remarks

Rated figure meets the criterion of GB/T 13331-2005/ISO 10576. Rated rollover loading is 75% of static rollover loading, rated limiting hydraulic weight is 87% of limiting hydraulic weight. Loading radius is the distance from the loading point to the swing center. The figure with * stands for the rated figure of the limiting hydraulic weight.

Hydraulic Lockout Control

When the hydraulic lockout control is placed in LOCK position, all controls are inoperable, which prevents accidents caused by unintentional operation.

Reduce Fatigue

The seat rigidity can be adjusted according to the driver’s weight, even if the big drivers can enjoy a comfortable operation.

Automatic Air Conditioner

The standard large-capacity air conditioner keeps in-cab air fresh by purifying fresh air and recirculation air. The quick temperature control ensures a comfortable temperature in cab all the year round.

Three Stage Air Filtering

Equipped with air pre-cleaner and dual air filtering elements, the three-stage air cleaner ensures supply of sufficient clean air that can reduce the wear of cylinders.
