Sunward SWE 50UF_MAINSunward SWE 50UF_MAIN


Sunward is excited to introduce the SWE 50UF mini excavator at the INTERMAT Fair in Paris, April 2024. This 5-ton model, positioned between the SWE 35UF and SWE 60UF, features a zero-tail swing, ideal for constrained spaces. It boasts a Kubota D1803-T engine, a bucket capacity of 0.14 m³, and a weight of 5.3 tons. With a user-friendly design including comfortable seats and a 7-inch color touchscreen, it ensures efficient control and easy maintenance. 

Building on the success of Sunward’s zero tail range, which earned an iF Design Award, the SWE 50UF continues the legacy of combining best value for money with award-winning design. This excavator is set to be a game-changer in the construction industry.

Sunward is proud to announce the launch of its latest mini excavator, the SWE 50UF, at the upcoming INTERMAT Fair in Paris, April 2024. 

This new model, expertly designed to fill the gap between the SWE 35UF and SWE 60UF, boasts a zero-tail swing feature, making it perfect for narrow space operations. 

The SWE 50UF is equipped with a powerful Kubota D1803-T engine, ensuring robust performance with a significant torque of 150 N·m/rpm. With an operating mass of 5.3 tons and a bucket capacity of 0.14 m³, it offers both efficiency and precision in various construction environments. 

The SWE 50UF stands out for its comfortable and intelligent cabin design, featuring shock-absorbing seats and a 7-inch color touchscreen for seamless flow adjustment and control. The large undercarriage enhances stability, especially on challenging terrains, while the high-displacement travel motor ensures easy mobility. Maintenance is made convenient with a full-open cover, allowing easy access to all parts. 

Furthermore, Sunward’s commitment to innovative design, as evidenced by winning an iF Design Award for its zero-tail range, is continued in the SWE 50UF. This new model is not only a testament to Sunward’s engineering excellence but also to its dedication to cutting-edge design in heavy machinery.

On top of its EU certification, the Sunward SWE 50UF, like all Sunward machines on the European market, is designed to meet European customer needs.


We chose the powerful Kubota D1703 engine for several good reasons. This engine is a vertical, water-cooled, 4-cycle diesel engine with a capacity of 29.7 kW at 2200 rpm. Featuring a built-in solenoid, low fan position, and single side serviceability, the Kubota D1703 offers powerful performance, exceptional reliability and long service life to meet a wide range of applications. The perfect fit for our reliable and versatile SWE 50UF.


All key components in Sunward excavators are carefully selected, from Kubota engine to hydraulics. Because hydraulics are often regarded as the heart of the machine, Sunward sources exclusively from the highest references in the market. For our Sunward SWE 50UF, we selected HENGLI to be our main supplier for the hydraulic pump, and KYB or Nachi for the swing motor traveling and swing motor. All these pumps and components for construction machinery are efficient, reliable, and space-saving. So, it’s no coincidence that Sunward selected them to contribute to the SWE 50UF’s reliability.


The SWE 50UF has exceptional digging forces – 34 kN (bucket) and 23 kN (arm) – easily rivaling all 5.5t excavator competitors on the market. And when it comes to its long-reach capacity, the SWE 50UF’s boom cylinder design provides a ground reach of over 5.8 meters (5 845 mm) and a digging reach that’s over 5.9 meters (5 940 mm) long – making this mini excavator the benchmark of its range.


A mini-excavator’s versatility starts with how well it is designed. The SWE 50UF is a zero-tail mini excavator with truly compact dimensions (2 000 mm width), allowing to bring power and easy work even if very tight areas, without any compromise on safety. Moreover, the SWE 50UF can adapt to any job site, thanks to the complete auxiliary settings built-in as standard – providing fully adjustable pressure and flow monitoring. This results in no less than 3 separate auxiliary lines as standard (while the market provides 1 to 2 lines as standard). Thus, a wide range of attachments can be easily fitted to answer a variety of applications.


This slightly Sunward SWE 50UF mini excavator has it all from the day it leaves the factory:
– Auto idle engine to save fuel and limit the engine’s consumption. – While other manufacturers usually use a flow throttle (because it’s cheaper), we at Sunward opt for a Load Sensing (hydraulic) system, which provides better energy-saving possibilities.
– Safety valves for the boom cylinder for safer operations.
– Auto-shifting traveling motor for smooth operations to the operator.
– TOPS & FOPS cab.
– Battery cut-off switch for safer operations and prolonged battery lifetime and power – which is especially appreciated in the cold weather of Scandinavian countries.
– Double Acting Hydraulic Circuit
– Factory-fitted Hydraulic Quick Hitch Lines
– Factory-fitted Hammer & Rotation Line
– Factory-fitted Case Drain Line
– Factory-fitted One hydraulic pilot control with a double contact switch
– Factory-fitted Tiltrotator Configured Joystick Controls (tiltrotator of your choice)
– 4 LED work lights as standard: 2 on the front of the cab, 1 on the left side of the boom, and 1 on the back


To reduce maintenance time and cost for the SWE 50UF, the covers at the rear and on the side provide direct access to the service points. The standard service points – for fuel, oil, and air filters – are directly accessed via the cover at the rear. So, with very easy access to the fuel tank and centralized grease fittings, these mini excavators are as easy to maintain as they are to operate.


Sunward is your smartest investment in reliability, performance, and high ROI. Indeed, the SWE 50UF’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.
