Komatsu PC55MR-5

Description

The Komatsu PC55MR is a compact 5-tonne-class short-tail mini excavator designed for confined areas such as yards, road works, demolition sites and sewer trenches. It has a tight tail swing radius and swing booms that hug the machine, giving more room to work. Compared with the PC50MR, it has greater digging depth and higher operating weight, and suits more demanding digging jobs.

In the model name, PC stands for Komatsu’s crawler excavators, and the number 55 refers to the size class.

Komatsu PC55MR specifications and weight:

The PC55MR-5 has an engine power of 29.1 kW (39 hp), an operating weight of 5,260 kg, a digging depth of 4.13 m and a bucket capacity of 0.16–0.18 m³. For full dimensions and technical data, see the data sheet or the supplier’s PC55MR-5 product page, and explore more options among Komatsu’s mini excavators.

Komatsu states that the new minis use up to five percent less fuel than their MR-3 predecessors, with no loss of performance or productivity. An auto decelerator and idle shutdown are standard, along with the first proportional hydraulic line. The machine has newly developed hydraulic electronic controls and selectable working modes.

The hydraulic system is a CLSS (Closed-centre Load Sensing System) with a variable displacement pump. It delivers power, speed and precise control for all movements, even when several are used at once, regardless of load or rpm. The machine has dedicated piping for a Lehnhoff Powertilt and a single-effect hydraulic quick coupler line, routed over the arm for better protection.

A high-definition 3.5-inch LCD monitor gives excellent visibility, showing alerts, machine information, operation records, settings and maintenance data in a simple format. It is little affected by viewing angle or ambient brightness.

The engine bonnets open wide for quick access to daily inspection points. The fuel and hydraulic oil tanks sit under the side bonnet in a safe, easy-to-reach position, and the cab tilts back for major maintenance. With Komtrax, Komatsu’s wireless monitoring system, you can track the machine, monitor its performance and stay up to date on its status.

For more power and capacity, the PC58MR represents a natural step up. For zero-emission work in smaller weight classes, see the electric Komatsu PC20E–PC33E.

Operating a mini excavator requires proper training. Hesselberg offers a heavy equipment operator course for certification and skills development.
