RailwayCare DMS-100: Adjustable Integrated Rail Drilling Machine

Powered by a 72V lithium-ion battery pack, the unit drives a high-torque brushless DC motor through a planetary gear reduction system, delivering stable rotational speed across the full drilling range—from φ9.8 mm (high-speed steel bits) to φ31 mm (carbide-tipped rail drills). Typical cycle times are ≤15 s for φ9.8 mm holes and ≤30 s for φ31 mm holes, significantly reducing track possession time.

Key operational advantages include:

●   Tool-free quick-chuck mechanism: Enables drill bit change in ≤2 seconds without auxiliary tools—critical for rapid response in emergency or multi-hole sequences.

●   Dual-axis alignment system: Horizontal positioning via calibrated pointer against reference marks; vertical position fine-tuned via a linear slide rail with ±20 mm travel—allowing accurate reaming of irregular or worn existing holes without rail damage.

●   All-steel clamping frame with elastomeric vibration isolation ensures secure rail engagement and protects internal components from shock loads during drilling.

●   IP54-rated enclosure safeguards electronics against dust ingress and water spray during outdoor operation.

The machine’s compact footprint (0.5 × 0.4 × 0.2 m) and low mass (≤9.8 kg, excluding battery) enable single-operator handling in confined spaces such as tunnels, switches, and bridge decks. It has been validated for reliable start-up and performance in temperatures from –20 °C to +45 °C, making it suitable for seasonal trackwork across diverse climates.

This drilling system eliminates the need for heavy pneumatic or corded alternatives, offering a safe, emission-free, and logistically simple solution for modern rail infrastructure maintenance.
