CRIBUS 3800 E

Introduction

Mobile drum screen

The Cribus 3800 E redefines the term mobile drum screen. 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 newly developed direct "WHEELGRIP" drum drive.

Advantages at a glance

  • Largest mobile drum screen as a central axle trailer
  • 15% more screen area and 15% more effective screen length versus competition
  • 20% more feed cross-section versus competition
  • Electrical drive of all components for highest energy efficiency
  • New drum drive concept without chain via patented “WHEELGRIP“
  • High degree of maintainability with optimal accessibility and no-maintenance solutions

Highlights

The biggest drum for the greatest performance

With a drum diameter of 7'3" and an effective screen length of 18'1", 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 fractions with larger shapes and sizes and a smooth screening-off process – even with the 4" screen hole size.

Cost savings with electrical drive

Alternativer

The power for the electrical drives comes directly from the mains, is generated by an integrated diesel generator or by a separate power generator.

Savings (mains operation/generator operation compared to hydraulic drive):

• up to 75% / 25% lower power consumption

• up to 30% / 15% lower costs for consumable parts

• up to 25% / 5% lower operating costs

Efficient drum drive

The new 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.

Servicing is a joy

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.

High degree of operator convenience

The machine is operated from outside the work area and has the highest level of operator convenience thanks to the fully electronic controller. The graphical display shows the operating status and all of the functions are clearly visible and easily configurable.
