Boost Performance with the MT 3000-2 Offset
Versatile VÖGELE feeder with pivoting conveyor
VÖGELE optimize the supply of mix on every job site with their new PowerFeeder generation. Here we present the advantages offered by the MT 3000-2 Offset.
Innovative pivoting conveyor
The innovative pivoting conveyor forms the centrepiece of VÖGELE Offset Technology. The 1.1m wide conveyor can be pivoted through 55° to both the right and the left, as well as 23° upwards, opening up a whole variety of potential uses. As a result, the mix at the end of the conveyor can be discharged up to 3.5m to the right or left beside the mobile feeder and at heights ranging from 0.8m to 3.7m. This makes the machine ideal, for example, for feeding pavers from the side, as well as for backfilling trenches or the spaces between safety barriers on motorways or long-distance roads. The feeder is also recommended for roadworks on hard shoulders.
Not only asphalt, but also gravel, water-bound base course mix, recycled material and topsoil are delivered right there where they are needed, with spot-on accuracy. Segregation of the mix is prevented at all times during the conveying process by the 30° troughed shape of the conveyor. What’s more, the conveyor is particularly lasting as the endless belts are industrially produced without seams.
“It is impressive to see how cleanly the mix is transferred to the paver. Hardly a single grain is lost by the feeder.” (Karl Keller, Mechanical Engineering Department F. Kirchhoff Strassenbau GmbH & Co. KG)

Intelligent automatic tensioning also contributes significantly to the conveyor belt’s durability: it is only tensioned to the maximum extent when absolutely necessary. In such cases, the belt tension increases until the drive power is transmitted 100%. Belt tension is reduced if a lower conveying capacity suffices. As a result, the belt is only tightly tensioned for short periods, extending its service life considerably.
Maximum conveying capacity for non-stop paving
A non-stop, non-contacting transfer of mix, such as is achieved by the feeder, is a decisive factor for perfect paving quality. Not only, but above all, on large-scale projects when large quantities of mix need to be transferred to one or more pavers as quickly as possible.
With the MT 3000-2 Offset, the highest possible conveying capacity is guaranteed at all times. For the high-performance PowerFeeder from VÖGELE takes just 60 seconds to empty a 25-tonne feed lorry. Several machine features make this possible. For one thing, the feeder’s material hopper can hold up to 8 tonnes of mix. The worm conveyors, proportionally controlled, and large worm blades (diameter 400mm) provide for homogeneous conveyance of mix without residues. Thirdly, the conveyor can transfer up to 1,200 tonnes of material per hour.
This high capacity considerably speeds up the job site logistics and leaves the lorry drivers more time to manœuvre. In this way, the entire machine concept ensures that paving can proceed without interruption, thus avoiding humps which often appear in the pavement when resuming paving after a stop.

The feeding process is complete. The mix has been distributed into the feeder’s receiving hopper and the extra material hopper of the paver.
A variety of potential uses
The new PowerFeeder MT 3000-2 Offset from VÖGELE is perfectly tailored for use when paving “hot to hot” with two pavers.
Large roads, such as motorways or trunk roads, are the best known area of use for mobile feeders. The new PowerFeeder MT 3000-2 Offset from VÖGELE is perfectly tailored for use when paving “hot to hot” with two pavers. Yet the offset technology is also ideal for filling the spaces between safety barriers on motorways or long-distance roads quickly and economically.
In addition, the mobile feeder also demonstrates its strengths when it comes to surfacing footpaths or cycle paths. With its pivoting conveyor, it can travel on the main road and conveniently transfer mix to a small or compact paver on the cycle path. The new VÖGELE PowerFeeder MT 3000-2 Offset is also used in an InLine Pave® train laying binder and surface courses “hot on hot” in a single pass. Its pivoting conveyor alternately supplies mix to the paver for binder course and the paver for surface course by way of a transfer module.
The versatile MT 3000-2 Offset can do far more than these few examples would indicate – and that pays off, as is confirmed by Daniel Stier, Site Manager for contractor F. Kirchhoff Strassenbau: “Thanks to the pivoting conveyor, the machine can be used most effectively.”
Feeding the paver from the side with the pivoting conveyor is particularly useful, for instance, when placing mix on a deeply milled out strip, with no possibility for a feed lorry to manœuvre.
The conveyor can be controlled with such precision that it is ideal for backfilling trenches of every kind.
Even spaces between safety barriers can be filled quickly and economically.
On confined sites, where a “normal” supply of the paver with mix is impossible, material can be transferred from the side.
Easy-to-use yet sophisticated operating concept
Like all machines of the VÖGELE “dash 2” generation, the MT 3000-2 Offset comes with the intuitive ErgoPlus® operating system. Fitted with two seats as standard, the feeder can be operated by one or two persons. On complex job sites, this allows one operator to concentrate exclusively on the conveying process transferring mix from the feed lorry to the paver, while the other operates the conveyor. The conveyor is controlled with high sensitivity via a newly designed joystick in the armrest of the driver’s seat.
To raise or lower the pivoting conveyor, the operator simply pulls the joystick back or pushes it forwards. The joystick is turned to execute a lateral movement. A safety switch prevents displacement of the conveyor due to accidentally touching the joystick: the afore-mentioned functions can only be executed when the safety switch is pressed at the same time.
.
The feeder’s conveying capacity is controlled by two push-buttons on the joystick. The yellow button sets the standard conveyor speed. This speed can be briefly overridden by pressing the white button if a particularly high conveying capacity is required. The conveyor speed is infinitely variable using the red control.
Of course, all vital functions of the conveying process can also be controlled from the operator’s console.
