Diamond wire saw is top of the tools

The new electropneumatic diamond wire saw was developed for large-scale demolition and civil engineering applications, including subsea cutting, hydroelectric dam dismantling and structural decommissioning.

The machine provides 50 kW of cutting power and 30 m of onboard wire storage, combined with a three-motor drive and pneumatic wire storage system designed to improve cutting performance and wire life.

Plattner said that the core engineering innovation of the DSW 5030-CA is its three-motor drive architecture, which it states is a world first for a diamond wire saw. Previous high-performance wire saws relied on single or dual motor configurations.

The system delivers “a step change” in available torque and power distribution, enabling 50 kW of cutting power on a 125A supply and 37 kW on a 63A supply. This gives operators the flexibility to deploy the machine across sites with different electrical infrastructures.

The DSW 5030-CA’s CutAssist control algorithm automatically adjusts drive parameters during operation, reducing the level of operator input required to maintain cutting performance.

A purpose-built GUI on the wireless remote control allows the saw to be operated from a distance, while an integrated cooling system maintains performance in high ambient temperatures.

Despite its cutting capacity, the machine has also been designed for mobility and rapid deployment between applications and sites.

In their citation, the judges were impressed by the three-motor system, with coordinated controls delivering smooth, efficient cutting while protecting the wire from overload.

They also highlighted the strong customer feedback which confirmed the high productivity and significant time savings.
