167 Benninghoven has developed a new mastic asphalt transport boiler that features an all-electric mixer shaft drive. The GKL Silence unit has an electric drive to power the mixer shaft. Flender SIP planetary gear units are used in conjunction with three-phase asynchronous motors as completely ready-to-install planetary geared motors from 1134 Siemens. This design allows the compact two-stage planetary geared motor to be adjusted to the output and speed range required.

Used in conjunction with a four-pole three-phase asynchronous motor, the maximum starting speed is around 7rpm at the mixing shaft. The optimum speed is 4rpm, which can be adjusted by the machine operator using a frequency control.

Compared with conventional hydraulic drives, the electric system offers a high control of speed range as well as quiet operation. This latter feature means that it can be used in areas where noise restrictions apply, extending the operation time. In addition, units can operate without the need for diesel power simply by connecting to a three-phase supply.

The drive system is said to be highly reliable and can be specified for use in challenging climates. The all-electric drive to the mixer shaft also allows the user to capture data and provide information for use in processing technology and servicing. And tanks with capacities of 5m3, 7.5m3 or 10m3 are available.

    Improved surface quality and improved machine design are key trends in the asphalt paving sector, Mike Woof reports There is a big difference in asphalt paving techniques in North America and Europe. In North America, the need to construct long stretches of highway quickly resulted in wide pavers offering high throughput capacity, with compaction equipment then being used to achieve the required density of the various courses. In Europe's highway construction projects, distances tend to be shorter and contr
