28 BAUER machines on a 142 km high-speed railway: what the Yerköy–Kayseri foundations show
On Türkiye's 142 km Yerköy–Kayseri high-speed line, a fleet of 28 BAUER machines is installing Kelly-drilled piles to 30 m and single column mixing columns to 31.5 m. The project illustrates how method selection and fleet coordination are planned on major linear infrastructure.
Tadano GR vs AC Cranes: Rough-Terrain or All-Terrain?
Choosing between a Tadano GR rough-terrain crane and a Tadano AC all-terrain crane is not a simple capacity comparison. The correct family depends on mobilisation, site movement, required load and radius, setup space, ground conditions and counterweight logistics.
Ammann and DEWALT electric compactors: battery power for plates and rammers
Ammann and DEWALT have introduced a battery-powered light-compaction range built around two forward-moving vibratory plates and one rammer. The models are the eAPF 15/40, eAPF 15/50 and eATR 68, retaining key compaction output while cutting noise and exhaust fumes.
How to Choose the Right Ammann Compaction Equipment
Compaction equipment should be selected from the material and required result, not machine size alone. A roller effective on clean gravel can be inefficient on wet clay, and a rammer suited to a narrow trench is inefficient on a large layer. This guide covers Ammann's range.
Kelly Drilling vs CFA vs FDP: Choosing the Right Foundation Method
Kelly drilling, Continuous Flight Auger (CFA) and Full Displacement Piling (FDP) all produce cast-in-place foundation piles, but solve different construction problems. The correct method depends on ground profile, groundwater, pile geometry, reinforcement and nearby structures.

KLEMM KR 806-4GM and KR 806-4E: two efficiency paths for anchor and pile drilling
At bauma 2025 KLEMM presented the KR 806-4GM with a Power-Sharing diesel drive and the KR 806-4E electrohydraulic rig. This article separates verified performance claims from marketing shorthand and explains which site conditions favour each approach.
Power Curbers acquires Miller Formless: what the expanded slipform range covers
Power Curbers Companies finalised its acquisition of Miller Formless Systems on 29 August 2025. Miller Formless continues under its own brand, and the group now holds four brands. This article sets out what the combined range covers and what to confirm before specifying a machine.
