On top of its EU certification, the Sunward SWE 335F, like all Sunward machines on the European market, is designed to meet European customer needs.

For the SWE 335F, we selected the medium-duty Cummins QSB6.7 engine. This engine with heavy-duty components and performance sets the industry standard for reliability and durability and enjoys wide popularity in the market, so it has an extensive service network.

Its increased fuel economy and longer maintenance intervals contribute to lower cost of operation and lower Total Cost of Ownership.

With near-zero emission levels, it complies with the European Union’s latest requirements and delivers 209 kW without compromising power, performance, or fuel economy.

Its incredible output of 209 kW rated at 2 000 rpm even makes it one of the most powerful – if not the most powerful – excavators in the 32-ton weight category.

As hydraulics are often regarded as the heart of the machine, Sunward sources exclusively from the highest references in the market. For the SWE 335F, we selected Japanese premium brands KPM for the hydraulic pump and swing motor and KYB for the Main Control Valve (MCV). Both highly reliable brands are known for their high efficiency and long-life components, designed specifically to meet the demands of hydraulic excavators.

The SWE 335F has been designed with durability in mind. The Cummins engine has built a reputation for high durability, even in extreme working conditions. Also, special attention has been put into the key parts of the SWE 335F, such as the boom and the arm, which are designed with an increased sheet material thickness. All supporting elements are made of high‑strength, high‑ductility, and structural steel die‑forged pieces. This has the great advantage of providing elements with both high wear resistance and structural strength. This process delivers a massive increase in reliability operating under heavy‑duty work. For example, the swingarm and bucket rod are designed with the reliability standard of 20 000 hours.

Also, the SWE 335F’s heavy-duty implements are delicately annealed, which completely eliminates the residue stress in weld seams and increases the machine’s reliability significantly. After welding, the natural cooling process (with the risk of uneven cooling) is prevented by heating the metal in an isolated chamber to 600 – 800°C and then cooled down slowly (5 – 8 hours), avoiding residual stress and defects. This kind of cooling process is usually not adopted by manufacturers who want to save time and money.

Last but not least, the X chassis has been reinforced, bringing excellent resistance to distortion.

Thanks to the inline turbocharged Cummins QSB6.7 engine, the SWE 335F uses less fuel, with improved total fluid efficiency (includes both fuel and Diesel Exhaust Fluid), with no compromise on performance (this engine has an even better performance compared to its previous version, delivering 8 percent more power and almost 13 percent more torque across the entire RPM range).

Sunward’s SWE 335F medium excavator also has the highest hydraulic efficiency, which results in low fuel consumption. With the new premium quality main pump from KPM, and the innovative thinking from Sunward, we increased the machine’s displacement by 7%, power by 4%, and volume efficiency by 6% – making the entire excavator more energy efficient).

Finally, thanks to the 3 attachment work modes, operators can enjoy versatility, but also fuel consumption optimization.

In the spirit of Sunward’s motto – ‘Innovation Leads to Value’ – the design and engineering of the SWE 335F is focused on generating optimal value for the machine’s owner while offering optimum versatility to the machine’s operator.

The SWE 335F can be used in a large variety of working conditions and applications. And thanks to the 3 separate auxiliary lines (2 of them are equipped with a shut-off valve for easy and oil leakage-free installation of attachments), the 3 bucket working modes, and the 3 attachment work modes, an operator needs only a few minutes to fully appreciate the possibilities offered.

The SWE 335F is as easy to maintain as it is to operate. To reduce maintenance time and cost, the covers on the side and the top provide direct access to the service points. With extremely easy access to the fuel tank and centralized grease fittings, we even added handrails to make it easier to get around the machine.

The high-strength SWE 335F cab meets ROPS, TOPS, and FOPS requirements, which are standard and among the first features to ensure a safe and comfortable job in all application environments.

To accommodate tall European operators, the cab is easy to climb in and out of; and its roomy interior provides a comfortable and efficient work environment. Everything is designed to keep operators comfortable, productive, and absolutely safe.

The safety pack – including fire extinguisher, safety hammer, and safety belt – contributes to total peace of mind.

Last but not least, the latest standard equipment is the rear camera – which complements the large windows and glass rooftop to provide a 360° view, allowing to work safely and efficiently, without stress.

Sunward is your smartest investment in reliability, performance, and high ROI. Indeed, the SWE 335F’s expert design includes a well-thought-out selection of components that streamline operation and maintenance. Our design choices result in a machine that provides so many standard features, premium-brand key components, and capabilities at the right price.

And furthermore, Sunward’s own genuine spare parts are economical as well – and all of this best value for money is crowned by up to 5 years of warranty, standard for all Sunward products.
