Mecalac TV1200 tandem vibrating compaction roller nominated for the innovation award for design at Bauma 2019

Mecalac TV1200 tandem vibrating compaction roller nominated for the innovation award for design at Bauma 2019

The Mecalac Group has built its innovative reputation on designing and producing construction machinery for urban job sites. Since the acquisition of the British facility at Coventry in 2017, backhoe loaders, site dumpers and compaction rollers have been added to the existing ranges of excavators and loaders.

Mecalac — Innovation useful to people  

Every Mecalac product shows a drive towards continuous improvement of performance, comfort, ease of handling and safety for the users and the entire job site.

In this way, Mecalac Group R&D brings differentiation through innovation useful to people.

TV1200, focused on two main areas of improvement  

Once a range of compaction rollers arrived among its offerings, Mecalac immediately looked for ways to improve both the efficiency of work and the safety of the driver. We started with the driver’s position. 

Most tandem rollers are manoeuvred using the wheel on the steering column. The presence of this steering column forces the driver to contort himself just to get into the seat. Once in position, he drives with one hand on the wheel, the other on the lever, all while keeping an eye on the trajectory of the front drum.

Fatigue, musculoskeletal problems and risks of falling when climbing on or off are problems inherent to this traditional design. So Mecalac R&D were given the twofold task of easing access and improving the driving position for effectiveness, safety and comfort. 

TV1200 — The trailblazer in a new generation of compaction rollers 

Within Mecalac range of six tandem vibrating rollers, the Mecalac Group chose the TV1200 to showcase its innovation. This new concept is driven exclusively with a joystick on the right console. In removing the rollers steering column, Mecalac has revolutionized the access and driving style of this type of machine. Access has never been this safe, and driving never this comfortable. The freed-up space lets the driver settle easily into position, the steps have been redesigned for easy access from any side, movements are fluid, and there are no obstacles to negotiate. With their back comfortably against the seat and right hand on the joystick, the driver has complete freedom to position their legs comfortably while keeping their eye on the work. With the steering column removed, the driver has a clear view of the major driving information. By offering joystick steering from the right console, Mecalac provides safer, simplified driving in line with new-generation human-machine interface strategies.

TV1200, a reinvented design

Then the Mecalac design had to be adapted to the TV1200. This is design in its original sense — an architecture in respect of efficiency, comfort, and the safety of the driver and all personnel on the job site.The roller’s entire architecture has been redesigned for better visibility to ease operation and respond to user demands.

The curves are redesigned, the shape of the roller support now integrates with that of the hood, and a front grille has been added. The TV1200 is a machine with classic Mecalac looks and adapted to road vehicle strategies. The driver is at the centre of this new design, thanks to innovative standards in ergonomics and construction machine architecture. It is safe and simple to use, once again confirming the Mecalac Group’s ingenuity and innovation.

The TV1200 tandem vibrating compaction roller has attracted the attention of the jury for the Innovation Award organized for the International Bauma trade show in April 2019. The Mecalac Group has been nominated in the design category.
