One of our favourite excavators that stand out for their performance is our 21-ton excavator. This advanced piece of machinery is a powerhouse in site preparation and excavation. Let’s consider what makes this excavator not just a machine, but a pivotal member of any construction team.
Engine and Performance
At the heart of this excavator is a net-rated 117.3 kW engine, providing a hefty 159.5 horsepower, ensuring that no task is too daunting. Its engine system is a leap forward in optimizing fuel efficiency and environmental performance. This system, paired with an advanced common rail fuel injection and turbocharger, not only enhances performance but also significantly reduces fuel consumption by 14% compared to its predecessors.
Hydraulic System
The excavator is equipped with an innovative fuel-saving hydraulic system. This includes spool stroke control, which variably controls the spool port flow rate, adapting seamlessly to the task at hand and improving operational speed while maintaining machine control smoothness.
Digging Power and Productivity
What sets this excavator apart is its real digging power. The combination of a large arm cylinder and improved hydraulics means that the machine’s arm-in motion slowdown is minimized, translating to effective power during excavation. It also boasts a 4% faster cycle time in SP mode, increasing productivity where it counts.
Durability and Maintenance
Durability is key for any construction equipment, and this excavator doesn’t disappoint. It comes standard with high rigidity attachments that ensure strength and longevity. Its maintenance system keeps pins and bushes fully lubricated, significantly extending service life by reducing abrasion and rattling. High strength castings used in the boom and arm, along with a strengthened swing frame, contribute to the excavator’s robust build.
Operator Comfort and Safety
This excavator is not only tough on tasks but also tender on its operators. It boasts a stylish and spacious cabin, a high-definition full-color LCD monitor, and an optional field-view camera monitor for increased safety. The newly designed safety cabin, with its reinforced structure, ensures operator safety, providing peace of mind alongside comfort. The ergonomic design of the cabin reduces operator fatigue, a crucial aspect during long working hours.
Efficiency and Eco-friendly Features
Its fuel efficiency technology doesn’t just save on operational costs; it’s also kinder to the environment. The excavator’s automatic power-boost and power-swing systems, along with one-touch/automatic idling system, ensure that the machine operates at peak efficiency without unnecessary fuel waste.
Technical Specifications
The engine is a water-cooled, 4-cycle diesel with a high-pressure common rail system, turbocharged for maximum performance. The hydraulic system is equally impressive, with dual variable displacement axial piston pumps for major operations and a gear pump for pilot controls. The maximum oil flow of 2 x 211 liters per minute indicates a machine ready to respond rapidly to operational demands.
Auxiliary Systems
With its auxiliary hydraulic system offering a pump flow of up to 422 liters per minute, this excavator is ready to handle a variety of attachments, making it as versatile as it is powerful.
This excavator is a testament to engineering excellence. It’s a machine that assures productivity through its powerful engine, state-of-the-art hydraulics, and commitment to the operator’s safety and comfort. It is a true workhorse, designed to meet the rigorous demands of modern construction with ease and efficiency. For those in the construction industry looking for a reliable and robust excavator, this machine should be at the top of the list.
