The SY135 is designed to help you work efficiently while maximizing your jobsite productivity. It has many features to help operators achieve the balance of power, smoothness, fuel efficiency and speed. You can depend on the SY135C to get the job done right and on time.

1. Main Configuration

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.

Matching engine output to the highest quality hydraulic components allows the independent systems to act as one and maximize fuel efficiency and machine performance.

2. High Performance/High Efficiency

Optimized Power Control

The engine is designed with four working modes. The working mode can be changed on the monitor according to different applications, which can maximize the operating efficiency and reduce the fuel consumption.

 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 system to conduct 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.

Innovative Electro-hydraulic Control System

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.An advanced computer dynamic control system (CDCS) determines engine output power as per the extreme load demand, achieving the optimum control of excavator-extreme load operation system.

High Reliability

Explosion relief

To improve the overall security of excavator, the additional explosion relief valve of boom and arm are supposed to prevent work device dropping suddenly because of the pipeline bursting.

Reinforced Boom and Arm

The 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. Which optimized deign, the boom and the arm can provide considerable working range and depth on the occasion of ditching, excavating and common construction.

Wearable Bucket

Standard reinforced bucket with highly rigid steel sheet, tips and side cutters can serve a longer period.

Capability Against Distortion and Bending

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

High-strength Swing Platform

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

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.

Control Levers and Joysticks

The control levers and joysticks designed and arranged according to ergonomic, can be operated easily. Each operation button is within the reach of operator.

Audible and visual alarm lamp

In order to safeguard the personal safety, it will send out sound and light warning when excavator is moved in the noisy or poor-sight environment.

Large Rear view Mirror and Alternate Exit

Rear view mirror is mounted on both sides of the cab, which can observe the situation behind the excavator without looking back. A cab window for alternate exit is also provided for operator to escape in case of emergency.
