Goldhofer’s latest addition to its STZ-VP family owes its name to 285mm tyres. The STZ-VP 285 is the company’s low-loader semitrailer with the highest load-carrying capacity. This STZ version, with the pendular axle technology, is available in configurations between three and 10 axles and a choice of decks - vessel bridge, crawler deck and flatbed.

Goldhofer’s latest addition to its STZ-VP family owes its name to 285mm tyres. The STZ-VP 285 is the company’s low-loader semitrailer with the highest load-carrying capacity. This STZ version, with the pendular axle technology, is available in configurations between three and 10 axles and a choice of decks - vessel bridge, crawler deck and flatbed. A technically permissible axle load of 16tonnes and a deck profile of just 200mm for the flatbed – the slimmest on the market – make this low loader unique, according to the company.
The STZ chassis features a combination of extremely wide excavator recesses and relatively short bogies. 1449 Goldhofer’s pendular axle technology provides precision-calculated geometry of the axle suspension for free oscillation of the wheelsets. The advantage is optimum distribution of the load to all the tyres and perfect levelling in uneven terrain. A steering angle of up to 65° rounds off the benefits with perfect manoeuvrability, the company said.
Axle suspension is available with tapered roller or compact bearings to meet requirements in terms of mileage and maintenance intervals. The excavator recess brings a reduction in overall load height. The use of the gooseneck with or without a front bogie and the option to combine the front bogies with the MPA-K family and the rear bogies with the THP family ensures versatility.
Also new from BOMAG are compact rubber tyred rollers for the 4.5-11tonne market. The new BW 11 RH-5 models are articulated and feature hydrostatic drives and suit use in compacting chippings on surface dressing. The central positioning of the articulated joint is said to allow the four rear wheels to roll in the gaps between the five front wheels even when driving round bends.
Special bitumen mixes and machines are capable of improving the service life of roads and reducing noise. Mike Woof and Patrick Smith report. The need to improve traffic flow in an important part of the City of Poznan, Poland, led to the decision to build a new 1.13km long dual carriageway.
Wirtgen has developed a novel control system for use on its concrete paving equipment. Matthias Fritz is the product engineer at Wirtgen tasked with developing the system. The new AutoControlpackage uses GPS technology to provide guidance for the machine's steering functions. Fritz added, "It has an augmentation centre for vertical control because it requires millimetre accuracy for height." This 3D control system is for use with the firm's SP15 and SP25 slipform pavers and is said to be a user-friendly, co
