POWERFUL & RELIABLE ENGINE
Achieving near‑zero emission levels, while delivering 120.6 HP without compromising power, performance, or fuel economy, that’s the challenge fully met by the compact and powerful Cummins QSF3.8 engine. This engine enjoys wide popularity in the market, and so it has an extensive service network. It’s the engine Sunward required to power the SWE155UF.
PREMIUM COMPONENTS
All key components in Sunward excavators are carefully selected, from the Cummins engine to hydraulics. Hydraulics are often regarded as the heart of the machine. That’s why Sunward sources exclusively from the highest products. For the SWE155UF, we selected a premium brand, KPM for the hydraulic pump and swing motor and KYB to be our main supplier for the Main Control Valve (MCV). Highly reliable brands that are known for their high efficiency and long‑life components, designing them specifically to meet the demands of hydraulic excavators.
BUILT TO LAST
The SWE155UF has been designed with durability in mind. The Cummins engine has built a reputation for high durability, even in extreme working conditions. With special attention on key parts of the SWE155UF, 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.
The SWE155UF’s heavy-duty implements are delicately annealed, which eliminates the residue stress in weld seams and increases the machine’s reliability significantly. After welding, the natural cooling process is prevented by heating the metal in an isolated chamber to 1112 – 1472°F and then cooling it down slowly (5 – 8 hours), avoiding residual stress and defects.
Last but not least, the X chassis has been reinforced, bringing excellent resistance to distortion.
LOW CONSUMPTION
Thanks to the inline 4-cylinder Cummins QSF3.8 engine, the SWE155UF uses less fuel, with total fluid efficiency (including both fuel and Diesel Exhaust Fluid) improved by up to 3 percent, with no compromise on performance.
Sunward’s SWE155UF 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.
DESIGNED FOR VERSATILITY
In the spirit of Sunward’s motto – ‘Innovation Leads to Value’ – the design and engineering of the SWE155UF are focused on generating optimal value for the machine’s owner while offering optimum versatility to the machine’s operator. The SWE155F can be used in a large variety of working conditions and applications. 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.
EASY TO MAINTAIN
To reduce maintenance time and cost, the covers at the rear and on the side open fully to provide direct access to the service points. With very easy access to the fuel tank and centralized grease fittings, the SWE155UF is as easy to maintain as it is to operate.
SAFE CAB
The high‑strength SWE155UF cab is standard and among the first features to ensure a safe and comfortable job. Despite its compact size from the outside, the SWE155UF offers easy access to the roomy cab. Thanks to the large windows and the well‑organized cab, everything is designed to keep operators comfortable and productive as well as safe.
BEST VALUE FOR THE MONEY
Sunward is your smartest investment in reliability, performance, and high ROI. Indeed, the SWE155UF’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. Sunward’s own genuine spare parts are economical as well – and all of this best value for the money is crowned by up to 3 years of warranty, the standard for all Sunward products.
