Vogele’s total solution ensures efficiency [Gulf Construction]

(Gulf Construction Via Acquire Media NewsEdge) JOSEPH Vogele, part of the German Wirtgen Group, produces not only individual technologies but also complete systems that logically follow one another to enable a hitch-free work process and more quality in road construction.


"The company's integrated system includes units that handle material management, machine operation, feeding the paver with mix, machine and screed technology, and process management – all forming a single unit in Vogele's quality philosophy," says a spokesman for the Germany-based company.

  Feeder technology Uninterrupted asphalt paving is based on the material management of the Vogele PowerFeeder. "High daily laydown rates with outstanding quality can only be realised in this way. Vogele's attention focuses particularly on ensuring that the mix is transferred to the paver with absolute precision and reliability, and without contact," says the spokesman.

Automatic distance control helps the paver operator to concentrate entirely on the transfer of mix. Additional safety is assured by the collision protection system: if there is any risk of a collision, the paver following behind the feeder is automatically stopped, thus preventing a potential collision.

Special technical solutions have been developed to prevent segregation of the mix as it is being transferred to the paver's material hopper. These include conical worm conveyors in the receiving hopper of the feeder and the trough-shaped belt conveyor that serve to homogenise the mix.

  Transfer PaveDock Assistant and PaveDock push-rollers from Vogele combine to ensure maximum process safety when transferring mix in road construction projects without a feeder, the spokesman says.

PaveDock Assistant is a simple and reliable communication system permitting optimum coordination between paver operator and feed vehicle driver. The signal lights mounted on the right and left of the paver's hardtop and the associated controls on the paver operator's ErgoPlus 3 console are key elements. The sprung PaveDock push-rollers efficiently absorb any jolts produced as the feed vehicle docks on.

  Material management "Effective, high-quality material management is crucial in assuring the quality of the end product – the road," says the spokesman. "The powerful and efficient material transfer system from Vogele operates without unnecessary transfer points, ensures a permanent flow of mix and prevents it from segregating. Use of a modern feeder of the Vogele PowerFeeder generation is a safe and economical way to obtain a top-quality mix for paving.

He says the extra material hopper for the paver has been designed without unnecessary edges and corners in order to optimise the flow of mix. "Gently rising conveyors in the paver and a particularly effective system of augers with large-diameter blades ensure a perfect head of mix in front of the screed," he says, adding that effective Vogele material management improves the quality of the paving mix tenfold as compared to classical paving without a feeder.

  Screed technology Vogele's screed technology has also been optimised during the development of the "dash 3" generation of pavers: the geometry of the tamper bar has been modified to give the screed a flatter planing angle, thus ensuring a high-quality paved result.

The SmartWheel on the operator's console is another major innovation that reduces  paving errors. This rotary controller lets the screed be set to the required pave width with absolute precision. Two speeds are available to extend and retract the screed at high or low speed simply by turning the SmartWheel.

Niveltronic Plus, the high-precision automated grade and slope control system, allows extremely even paving true to line and level on any base. This system uses a variety of sensors which can be adapted quickly and flexibly as required. Irregularities in the base are reliably detected and compensated so that the roadway can be produced with the required evenness and layer thickness.

  Automated processes AutoSet Plus has two automatic functions: the repositioning and transport function greatly facilitates the continuation of work when moving the paver from one work section to another, or after the paver has been transported. Simply pressing the execute button quickly and reliably readies the paver for moves on the job site or for transport. Pressing the button again returns the machine to the previously stored working position.

The automatic function for paving programmes, on the other hand, allows the operating personnel to store specific paving programmes in the paving process. Values for tamper and vibrator speed, conveyor and auger speed, height of the auger and pave speed are stored at the push of a button. Once stored, the programme can be retrieved and reused whenever needed.

By automating recurrent functions with AutoSet Plus, quality can be improved and the paving process made more convenient.

  Measurement technology With the thermographic RoadScan module from Vogele, the temperature of the asphalt can be measured directly behind the screed. The results are made available to the paver operator and/or site supervisor in the form of significant values and clearly laid out graphs. In this way, the quality of the mix can be monitored and documented during the paving process.

"If Vogele RoadScan is used in combination with Witos Paving, the 'Analysis' module delivers comprehensive assessments which provide significant basic information for the site supervisor, paving crew and manager of the mixing plant," says the spokesman.

What's more, the measured values can also be continuously forwarded to the Hamm rollers involved in the process and their HCQ Navigator for documentation and analysis of the resultant compaction. Compaction quality can constantly be improved in this way.

Witos stands for Wirtgen Group Telematics and On-Site Solutions. With this, the Wirtgen Group offers extensive, high-grade telematics solutions for fleet management and services, as well as for optimising work processes in road construction.
