Rail Fastening Rails Dennik Clip

Railway Clip is used to fasten the rails to the underlying base plate together with the concrete sleeper. A variety of different types of heavy-duty clips are used to fasten the rails to the underlying baseplate or Sleeper, one common being the E Clip, which is shaped like a stubby paperclip. Another one is the SKL Tension Clamp, which is also the most widely used type all over the world. Others like KPO Clamp and Nabla Clip, also used in different situations.

Description

Technical Parameters

Railway Dennik Clip - Technical Data Sheet (Alternate Version)

Feature	Specification
Product Name	Dennik Clip (Standard A.R.E.A. Style Clip)
Governing Standard	A.R.E.M.A. (American Railway Engineering and Maintenance-of-Way Association) Chapter 5 - Track
Primary Function	To provide a durable, high-retention fastening solution for wooden tie tracks under extreme freight loads.
System Compatibility	Designed for use with cut-spike tie plates on timber sleepers in ballasted track.
Key Characteristic	"Drive-In, Locked-In" mechanical interlock design, offering exceptional resistance to both vertical lift and longitudinal creep.
Material	Spring Steel UNS G51600 (AISI 5160) or equivalent, known for high toughness and fatigue strength.
Heat Treatment	Through-hardened and tempered to achieve a uniform microstructure for consistent performance.
Surface Treatment	Industrial Black Paint or Black Oxide for basic corrosion protection and visual inspection.
Installation	Driven into a pre-punched hole in the tie plate's shoulder using a pneumatic impact hammer with a dedicated driving bit.
Clamping Force (Toe Load)	Extremely High, typically 14 - 18 kN, crucial for preventing rail turnover on curves under heavy axle loads.
Design Focus	Mechanical Reliability over installation speed. The design prioritizes maximum service life with minimal maintenance in grueling conditions.
Typical Axle Load Application	> 35 Metric Tons (e.g., North American Heavy Haul Freight Networks).
Key Advantages	• Near-Zero Probability of Vibration-Induced Unseating • Superior Longitudinal Restraint (Anti-Creep) • High Tolerance for Tie Plate Wear • Simplified Field Inspection (Visual check for full seating)

Application Context: North American Heavy Haul

Component	Compatibility with Dennik Clip	System Role
Sleeper	Timber / Wooden Tie	Primary foundation, with the clip's bite providing key holding power.
Tie Plate	A.R.E.M.A. Standard Cut-Spike Plate	The plate's hardened shoulder houses and locks the clip.
Rail Section	136 RE (or heavier), 115 RE (A.R.E.M.A. Standards)	Provides the base for the clip to bear upon.
Operating Environment	Heavy-Haul, Unit Trains, Mountainous Terrain	Where high traction forces and dynamic loads are prevalent.
