Achieving near zero emission levels, while delivering from 55 to 98 kW 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 SWE 155UF - and the fact that it complies with the European Union's Stage V emission requirements goes without saying.
All key components in Sunward excavators are carefully selected, from Cummins engine to hydraulics. Hydraulics are often regarded as the heart of the machine. That's why Sunward sources exclusively from the highest references in the market. For the SWE 155UF, we selected Japanese premium brands KPM for the hydraulic pump and swing motor and KYB to be our main supplier for the Main Control Valve (MCV). Both highly reliable brands are known for their high efficiency and long life components, designing them specifically to meet the demands of hydraulic excavators.
The SWE 155UF 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 155UF, 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 155UF'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.
In the spirit of Sunward's motto - 'Innovation Leads to Value' - the design and engineering of the SWE 155UF is focused on generating optimal value for the machine's owner while offering optimum versatility to the machine's operator. The SWE 155UF 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.
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 SWE 155UF is as easy to maintain as it is to operate.
The high strength SWE 155UF cab meets no less than FOPS, TOPS, and ROPS requirements, which are standard and among the first features to ensure a safe and comfortable job in all application environments. Despite its compact size from the outside, the SWE 155UF offers easy access to the roomy cab, welcoming operators of all sizes from everywhere in Europe. Thanks to the large windows and the well organized cab, everything is designed to keep operators comfortable and productive as well as safe.
Sunward is your smartest investment in reliability, performance, and high ROI. Indeed, the SWE 155UF'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
