Rokla GmbH Offers Blasting Alternative


German manufacturer Rokla GmbH has begun production of the latest generation of Webster Hydraulic Cutting Units under the brand name “Rockwheel.” The company is collaboration between Rokla GmbH and British engineer Ian Webster.

The Rockwheel is suitable for use in quarrying, demolition and building renovation, roadwork, trench construction, civil engineering, tunnelling, cutting slots and ditches, frozen ground, special underground engineering, removal of tree stumps and extraction of materials. According to the company, the Rockwheel can be a strong alternative whenever blasting is forbidden or not practical. Rockwheel cutting units work just as well underwater as in dry conditions without having to be modified.

“Our three-part Rockwheel cutting units provide the required maximum performance at all times but are significantly lighter in weight than those of the direct competitors,” said company founder Robert Piasecki. “As a result it is possible to achieve a powerful performance with Rockwheel cutting units – even with smaller excavators.”

All Rockwheel cutting units are equipped with high-torque hydraulic engines and are designed so that the picks, which are mounted on the drums at an optimal angle, can penetrate the material with maximum power.

In the middle-sized and medium-performance class, the Rockwheel cutting units have only three main components: the housing, motor and cutting heads (with picks). Currently the largest Rockwheel cutting unit being produced is for 4-ton excavators with a power of 140 kW to 220 kW.

The cutting heads of the cutting units operate smoothly and quietly while operating and rotate at a speed that achieves outstanding excavation and ensures a clean profile, the company said. The design and power components cutting units are adjusted so that the picks grip strongly and hardly ever bounce.

The Rockwheel is available internationally.
