33.5T Medium Excavator SANY SY335C Highlights

The 36 Ton Medium Excavator SY335C is a SANY excavator uses a high efficiency and low consumption engine customized for SANY that enables optimized power control, faster work speeds, and a full-power variable main pump. These features of the excavator paired with world-leading positive flow control technique, faster arm speeds, and reduced pressure loss improves upon efficiency, cooling and productivity.

Powerful Travel Ability of the Excavator

The new medium SANY excavator enables more powerful travel movement and ability due to a new arm regeneration circuit. This provides faster digging speed and lower energy loss. Other factors include the following:

• Large-torque travel mechanism
• Travel pilot valve with a dampening device to absorb vibration and reduce fatigue
• Secondary boosting technology to spread out excessive force
• Improved swing precision and control
• Optimized main valve provides excellent movement and coordination
• Reduced arm oil pressure loss and improved operation speed
• Ability to select working mode for heavy duty, standard, light duty, and breaker mode

Quality Excavator Comfort and Cab Safety

The excavator provides various features for environmental safety for the vehicle and cab operator including:

• Innovative large cab uses an adjustable seat, has suspension and supports the cab drivers weight
• Longer control levers for ergonomics and ease of use
• Pressure sealed cab to maintain a higher pressure in the cab to keep dust out
• Automatic air conditioner
• Silicone rubber shock absorber
• Anti-tipping and falling object protection structure
• Pump and engine screen
• Anti-skid plates
• Larger view mirrors and an alternate exit
• High-strength top plate

HIGH EFFICIENCY AND LOW CONSUMPTION

Engine Customized for SANY

• 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 high efficiency and low fuel consumption under different working mode, while optimizing the combustion.
• Compared to the SY330C, the updated SY335C improves its performance in several aspects, the arm digging speed increasing by 19 percent, the arm unloading speed raising by 25 percent, the boom boosting speed up by 10 percent, and the machine operating efficiency increasing by 20 percent.

Powerful Travel Ability

• The latest Nabtesco large-torque travel mechanism is adopted to enhance the driving force and reliability, making the travel motor driving force increased to 290KN.
• The latest Kawasaki large-torque swing mechanism is employed to increase the rotary torque by 32 percent, to 132.8 kN.M. The swing starting torque is also enhanced with reduced swing drift.

COMFORTABLE OPERATION

• The spacious and sealed cab is not only creating quiet environment for the operator, but ensures the air pressure inside is higher the outside, preventing the dust invasion. The innovative silicone rubber shock absorber, equipped in the operator station, minimizes the shock brought by the rough road condition or hydraulic impact, considerably increasing the stability of the cab and improving the comfort of the operator.
• Multiple air outlets at different levels and locations give the operators more comfort, especially under stuffy environment.

SAFETY

Falling object protection structure

The cab is punch-formed with thick high-strength steel sheet, and the toughened glass-made door and window, together with the equipped seat-belt, creating a quite safe environment for the operators.

Much more extensive view

The improved cab design elements the previous narrowed blind zone, by reducing the colomn size and decreasing the structural strength of the cab.

EASIER MONITORING AND MAINTENANCE

• Additional oil drain valve on swing mechanism makes gear oil replacement much easier.
• The accessible oil filter installed far away from the engine ensures easy maintenance.
• The radiator, fuel tank, hydraulic oil tank and oil pan are equipped with screw plugs at the bottom, which is convenient for discharging the exterior substance and waste liquid.
