Redefining performance for wheeled excavators

Combining compact design with impressive versatility and stability, the Mecalac MWR range of wheeled excavators make them ideal for urban construction sites and tight workspaces.

The most important features of wheeled excavators in helping them perform efficiently are their stability, manoeuvrability and accessibility.

They are characteristics recognised by innovative and compact construction equipment builder Mecalac, whose wheeled excavator range incorporate designs which address those three key issues.

As Mecalac director Phil Shepley tells Earthmoving Equipment Magazine, the business was able to identify areas for improvement for wheeled excavators after observing its customers work on construction sites.

"The very architecture of this type of vehicle, connected to an oscillating axle under the undercarriage and an upper carriage, gives it an intrinsically higher centre of gravity," he said.

"This results in a lack of stability which leads to discomfort and insecurity." Mecalac's MWR range counters these problems with clever reconfigurations of the way excavators are built.

Stability

"Lowering the centre of gravity has proved to be the key in maintaining balance," Phil said.

"This is achieved by lowering the top of the machine to be BETWEEN the wheels, rather than on top of them like conventional wheeled excavations.

"All the components in the upper carriage have been lowered as much as possible, and the shapes of the upper carriage and undercarriage have been completely redesigned around the oscillation of the wheels.

"With this, a new standard of lifting stability and performance has been born.
