Cribus

Drum screen with electric drive

The Cribus is a mobile drum screen for the highest demands. Numerous innovations create a machine with the highest level of functionality and cost-effectiveness and at the same time set new benchmarks.

The drive system represents the foundation for the extremely high degree of cost-effectiveness – everything on the Cribus is driven electrically, from the hopper to the discharge belts. This minimizes the energy, wear and servicing costs of the whole machine, supported by the direct “Wheelgrip” drum drive.

Advantages of the Cribus

For greatest performance

With a drum diameter of 2200 mm and an effective screen length of 5500 mm, the Cribus has the largest screen area of its class. The feed cross-section to the drum, the drum diameter itself and the unsurpassed gap to the side walls allow a smooth screening-off process – even with large screen hole size.

Advantages of the Cribus

Savings with E-drive

The power for the electrical drives comes directly from the mains or is generated by an integrated diesel generator. Savings (mains operation compared to hydraulic drive):

  •  up to 75% lower power consumption
  •  up to 30% lower wear costs
  •  up to 25% lower operating costs

Advantages of the Cribus

Efficient drum drive

The drive via friction wheel, as an all-wheel drive with the patented “Wheelgrip” technology, has the highest degree of efficiency and at the same time reduces to a minimum the costs attributable to wear and servicing since there are no chains, cogwheels or additional bearings.

Advantages of the Cribus

Maintenance made easy

Simply fold down the side wall to access the drum. No tools are required for exchange. The drum is lifted up with support arms and then removed using lifting gear or fork arms. Large flaps provide excellent accessibility to the whole of the engine compartment. The generator unit can be retracted or set up externally.

Advantages of the Cribus

Mobility the way you want it

Despite its impressive size, the Cribus is easy to manoeuvre as a semitrailer. Operation and maintenance are also easy and convenient. The operating panel with graphic control, automated startup and electric brush adjustment, plus options like hopper sensor control, remote control and more make this machine exceptionally operator-friendly.
