APPLICATIONS

Railroad Track Installation & Maintenance

The KT-SD70 delivers reliable 1,200 BPM impact power to quickly drive steel spikes into hardwood railroad ties during track repairs, switch work, and routine yard maintenance. Its balanced 70 lb class design cuts down worker fatigue while maintaining the heavy-duty driving force needed for commercial railways and crane rail systems.

Marine Piers, Docks & Waterfront Construction

Built for tough marine environments, this pneumatic spike driver securely fastens heavy timber decking, pier caps, and retaining bulkheads. The lighter-weight profile gives dock builders the control they need to drive long timber spikes over water without losing pneumatic hitting power.

Underground Mining & Tunnel Operations

This compact air-powered driver is ideal for tight, low-headroom spaces where crews must secure haulage rails, timber cribbing, and tunnel roof supports. An integrated internal oiler and durable 4-bolt back head ensure steady, trouble-free operation across dusty underground mine shafts.

Bridge Trestles & Heavy Timber Framing

Engineered for elevated wooden bridges and large-scale timber framing, the tool easily drives structural fasteners and large drift pins through dense wood beams. Contractors benefit from high-impact energy combined with a shock-absorbing rubber grip for safer, more comfortable handling on high trestles and retaining walls.

  • Swivel air inlet connection

Frequently Asked Questions (FAQ)

  • What air compressor size is required to run the KT-SD70?
    The tool requires an air compressor delivering at least 63 CFM at 90 PSI via a 3/4-inch NPT air hose. Use a compressor rated at 70+ CFM for steady, continuous driving.

  • What is the maximum operating pressure (PSI)?
    Run the tool at 90 PSI (6 bar) for optimal performance. Never exceed the 100 PSI (7 bar) maximum limit to prevent internal damage and tool failure.

  • How do you lubricate and maintain the KT-SD70?
    Fill the built-in internal oiler daily before every shift using pneumatic tool or rock drill oil. Regularly inspect the 4-bolt back head to ensure all bolts remain torqued tight.

  • What safety steps are required before servicing or changing parts?
    Always shut off the compressor, disconnect the air supply, and bleed line pressure before changing parts or servicing. Install an inline shut-off valve at the air line end for fast disconnection.
