1. Main Configuration

The main configurations such as engine, pump and valve are co-designed with internationally famous manufacturers, but Sany owns the intellectual property to make sure the outstanding property, satisfying the specialized demands of Sany’s customers.

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.

Main Valve

high reliablity and little pressure loss, high efficiency in flow distribution and conpound control action.

Isuzu 6BG1 engine

In line with EPA Tier lI and EU Tier II Emission Standards，easily solve the heavy load working condition problems.

2. High Perfermance

High Efficiency

Optimized Power Control

With closed-loop control, the controller automatically regulates the power absorbed by hydraulic pump according to the changes of engine load during the operation, keeping the power of hydraulic pump matching up to the power of engine at all times.

Faster Arm Speed

A quick circuit is added to the arm oil cylinder circuit.

Pressure Loss Reducing

The positive flow hydraulic system and the advanced computer dynamic control technology are used to provide real-time match between engine power and main pump power while effectively maximizing the machine performance and significantly reducing the fuel consumption.

Efficient Electric Control Module

The electric control module has the capability of making quick response to the change of operating variables in order to achieve optimum engine performance.

High Reliability

Excellent Cooling Effect

Fan Guard: The radiator fan is enclosed with a protective net cover that prevents objects from falling into the fan to damage its blades.
Serially Arranged Coolers: water radiator, oil radiator, intercooler and condenser are arranged side by side; the aluminum radiator gives better cooling effect.

Six Cylinder Diesel Engine

Six-cylinder engine ensures high reliability and stability of the machine as a whole.

Displacement 6. 494L

With the engine power of 128.5kw, SY235C has a displacement up to 6. 494L, which reduces the engine heat load and gives a longer service life.

Strong structure

Six-cylinder engine ensures high reliability and stability of the machine as a whole.

Displacement 6. 494L

High-strength machine:
Reinforced X-frame modeled with digital tools, through finite element analysis on loading capacity realizes high-strength structure.

High reinforced swing platform:

Reinforced plates, welded on the two main beam of swing platform, considerably improve the bending resistance performance.

Environmental Friendly

High Economy

Advanced computer dynamic control technology (CDCS) provides real-time match between engine power and main pump power, realizing the perfect combination of power and economy.

Auto Deceleration System

The function of auto deceleration or acceleration reduces fuel consumption by 5-10%. When an operation has been stopped for 3 seconds, the engine speed drops automatically to idle level and maintains the idling state.

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.

3. Operating Environment

Innovative Large Cab

The innovative large cab is equipped with an adjustable seat with suspension. The rigidity of seat can also be adjusted according to the operator's weight.

Silicone Rubber Shock Absorber

The operator station is supported with innovative silicone rubber shock absorber, which hasminimized the shock brought by rough road and engine or hydraulic impact, considerably increased the stability of cab, and improved the comfort of operator.

Longer Control Levers

The control levers and joysticks designed and arranged according to ergonomic, can be operated easily.

Falling Object Protection Structure

The top plate of cab is punch-formed with thick high-strength steel sheet integrated with reinforced ribs, which maximizes the safety of operator.

Hydraulic Lockout Control

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

Multi-functional LCD Monitor Ensures Easier Monitoring and Maintenance

Large LCD monitor can ensure safe, precise and stable operation. This LCD can be easily read from various angles under different light conditions. It equips with the functions of monitoring, maintenance and failure memory.
