Transverse cutting units at heart of innovation campaign

Rokla GmbH has launched an innovation campaign under the brand name Rockwheel.
The novel, extremely powerful transverse cutting units are robust, reliable and versatile, and available in various sizes. They are now available in the Australian market at competitive prices from local distributor Semco Equipment Sales, based in New South Wales.
The Rockwheel cutting units combine British ingenuity with decades of experience in cutting design and carry the ?made in Germany? quality seal. Components are sourced entirely from renowned German suppliers and assembled by skilled tradesmen in Baden-W?rttemberg.
Rokla GmbH was founded by Robert Piasecki and Klaus Volkert.
The company has its headquarters and manufacturing plant in Langenburg and produces a wide range of gearless cutting units, as well as cutting units with gearboxes in the lower to high performance category. Until recently the business partners (and friends) held executive posts at the construction equipment manufacturer Terex.
In the run up to the current reorganisation of the business division Terex Compact, they decided to leave the company and to start their own business based on the latest Webster cutting technology designs.
In the middle sized and medium performance class (from 10 to 40 tonnes), the Rockwheel cutting units have only three main components: the housing, motor and cutting heads (with picks). Engineer Webster has dispensed with gearboxes on smaller 10 to 40-tonne excavators, arguing they offer no advantage but cost money.
?Our three-part Rockwheel cutting units provide the required maximum performance at all times but are significantly lighter in weight than those of the competitors,? Piasecki said.
As a result, he added, it is possible to achieve a powerful performance with Rockwheel cutting units, even with 
smaller excavators.
The largest Rockwheel cutting units produced ? the G45 and G55 ? feature housing, motor and cutting heads, 
with gearbox. These powerhouse units are designed for excavators of 40 tonnes and above and have power capacity of 140kW to 220kW.
All Rockwheel cutting units are equipped with high torque hydraulic engines and are designed so the picks, which are mounted on the drums at an optimal angle, can penetrate the material with maximum power.
The cutting heads of the smooth, quietly operating cutting units rotate at a speed that achieves outstanding excavation and ensures a clean profile. The design and power components of the low vibration cutting units are perfectly adjusted, ensuring the picks grip strongly and hardly ever bounce.
The Rockwheel range is suitable for use in environments/applications including demolition and building renovation, roadwork, trench construction, civil engineering and extraction of materials.
Hydraulic transverse cutting units have proven to be a strong alternative whenever blasting is forbidden or impractical.
