As a common feature and denominator to all Mecalac excavators, the unique 3-piece-boom with integrated offset, provides the machine with unmatched compactness and versatility. On this basis, Mecalac has developed the MCR range, new innovative concept based on the perfect fusion of a loader with total rotation and a compact crawler excavators 10 km/h high-speed.Mecalac has chosen the 8MCR model to develop the first machine of its offer specialized for work in rail applications: the 8MCR Road-Rail.The 8MCR Road-Rail provides the optimum in compactness allied with highest-in-class performance - required for the majority of service work and railway maintenance.

23KM/H BALANCEThe superior balance of the 8MCR is the basis of numerous benefits of the Mecalac Rail-Road machine.The patented design of the Mecalac boom gives the machine an extraordinary weight distribution. Together with the tracked chassis the machine achieves highest-in-class stability, combined with uncompromi-sing compactness and maximum performance.

COMPACTNESS> The rear short radius assures that the machine works within

the minimum clearance outline> The allround compactness allows easy handling in tunnels

or the subway network> High maneuverability in constricted or cramped working areas> The patented boom kinematics allow to work in minimal

proximity of the machine> An integrated boom offset makes for increased flexibility and a

larger working radius> Transport possible on a standard-size 6x4 truck or a tipper lorry

VISIBILITY

PERFORMANCEThe 8MCR Road-Rail excavator is the ideal solution for users, looking for a compact machine with high performance. The key values are unique: > Load handling of 3 tons at a distance of 2.5 m from the

center of the rail track> Lifting of 1 ton in a full turning radius of 4.5 m distance> Loading of 600 kg at a maximum reach of 6 m> Ability to use hydraulic attachments usually used

by larger size machines, such as the special railway clamshell, a ballast tamping head or a mechanical or hydraulic sleeper layer.

The machine provides the operator with a natural 360° visibility. This assures that the driver is at all times aware of what is happening around the machine – on the rail track or next to it.There is no counterweight in the rear field of vision, and the Mecalac boom, with its high level of flexibility, that adapts precisely to every condition of the work site. The 8MCR Road-Rail has been designed for total operator vision on the work area and its environment.
