Features & Benefits

Boost productivity by up to 27% in the 55-tonne EC550, boasting levels of performance more commonly found in a 60-tonne machine.

Set new standards

This true 55-tonne crawler excavator, equipped with large bucket, boosts productivity by up to 27% – setting new standards for the industry – combined with the digging forces and lifting capacity more commonly found in a 60-tonne machine. With the China IV compliant engine delivering impressive power and reinforced digging equipment with large pin size, this is an excavator which is big on performance.

Proven engine technology

The China IV compliant Volvo engine has been tried and tested throughout the world since 2014. With technology that has been tested, proven, and enhanced for almost 10 years, this is an engine which customers can rest assured will deliver outstanding levels of quality, reliability, and efficiency.

Heavy-duty undercarriage

Handle heavy loads in even the most challenging conditions thanks to the long, wide lower frame, and robust undercarriage, which provide superior levels of stability and durability. The high-grade 60 tonne caliber undercarriage is in a class of its own, featuring reinforced track link and pins as well as enlarged rollers and shafts.

Right-sized buckets

The EC550 is available with a range of optimum-sized heavy-duty rock buckets especially designed for use in abrasive conditions. The Volvo Tooth System makes easy work of teeth replacements thanks to its place, push and click functionality.

On-Board Weighing

Take control of your productivity and ensure you load the optimum amount of material with On-Board Weighing, part of the Dig Assist suite of tools. The optional system provides real-time information to eliminate under and overloading of haul trucks. The system also records total tonnage for complete production management.

A number of features, including the next generation electro-hydraulic system, contribute to a fuel efficiency improvement up to 23%.

23% more fuel efficiency

Take fuel efficiency to the next level thanks to the next generation electro-hydraulic system with Independent Metering Valve Technology and optimization of the motor/hydraulic pump combination, which lowers engine rpm while optimizing power. The result is a fuel efficiency improvement of up 23%.

Unique Independent Metering Valve Technology

The latest pioneering innovation from Volvo, the next generation electro-hydraulic system with Independent Metering Valve Technology (IMVT) is the most high-performing hydraulic system in the industry. It provides significantly more precise control on the hydraulic system compared to a conventional system, contributing towards unrivalled levels of controllability and efficiency.

Get the most from your machine

While reliable and efficient machines of course play a vital role in reducing costs, enhancing safety and maximizing productivity, it is ultimately the performance of the operator that really makes the difference. We offer a wide range of training initiatives to help operators unlock the full capability of their Volvo excavator.

The best mode for the job

Unique Volvo technology incorporates work modes within the throttle control, for optimum performance. When the operator selects a work mode – I (Idle), F (Fine), G (General), H (Heavy) and P (Power) – the rpm is already set for maximum efficiency.

Machine monitoring made easy

Maximize machine uptime and reduce repair costs with the new Pulse telematics system. Choose to keep track of your machine yourself – including location, condition, reports and more – or let us take care of it with Volvo Active Care. Our Volvo Uptime Center will provide 24/7 machine monitoring, supplying weekly reports and notifying you should preventive maintenance action be required.

With low noise, low vibration and best-in-class visibility, the Volvo ROPS cab provides the ultimate in operator comfort.

Industry-renowned cab

Step inside the best cab on the market. The ROPS cab exceeds industry standards for this class of machine, and with low noise and low vibration, operators will experience the ultimate in comfort. Already boasting best-in-class visibility, the optional Volvo Smart View enhance visibility even more.

Customizable control pattern

Get ready for the working day in no time with customizable settings, including preferred control patterns easily selected from the monitor. Operators can also choose a function to be easily controlled via a shortcut switch on the joystick.

Motion priority functions

Operators can easily select and adjust a number of functions depending on personal preferences and the task at hand, including Boom/Swing and Boom/Travel priority which enables prioritization of one function over another. Operators can also easily adjust the boom down speed, ideal for precision tasks which require optimum control.

Boom and arm bouncing reduction

Boom and arm bouncing reduction technology dramatically reduces machine shock, resulting in a more comfortable and productive operator performance.

Creep mode

The perfect solution for lift and carry operations, creep mode utilizes an independent pump flow during travel to maintain a constant and slower travel speed.

Keep uptime to a maximum thanks to easy machine access and conveniently located service points.

Straightforward servicing

Grouped filters accessible from the ground level make servicing quick and easy, while the 3-point right-hand access ensures the upper structure can be accessed with confidence when needed. Industry renowned features such as bolted anti-slip plates, high visibility guardrails and handrails and large walkways further ensure the highest levels of safety when servicing the machine.

Long service intervals

Reduce operating costs and boost uptime with long service intervals. 5,000 hour hydraulic oil and 2,500 hour hydraulic oil filter change intervals minimize disruption to your operation, helping you achieve uninterrupted productivity for longer.

Engine protection

Keep your turbocharger working in top condition for longer with the optional delayed engine shutdown. To avoid overheating, the intelligent function turns the machine off when the turbo charger has cooled down to the appropriate temperature – and can be set to activate automatically by the operator.

Machine monitoring made easy
