Rail Threader: Hydraulic Rail Transfer Guide for Track Laying

Moving long steel rails into position is one of the slowest, most labor-intensive steps in track construction. Dragging rails causes friction damage, misalignment and injury risk. The Rail Transfer Guide (Rail Threader) solves it: a hydraulic attachment for 6–9 ton excavators that lets rails roll effortlessly into place with full 360° rotation and precision clamping control.

Why Track Crews Choose the Rail Threader for Rail Handling

Rail installation crews battle three problems: heavy rails that resist movement, tight alignment tolerances, and limited track-access windows. Manual threading with crowbars and rollers is slow and unsafe. The Rail Threader eliminates all three:

• Low-Resistance Rolling: Vertical and horizontal rollers let rails glide along the guide with minimal friction — no dragging, no scoring.

• 360° Rotation + 45° Tilt: The hydraulic tiltrotator positions rails at any angle without repositioning the excavator.

• Precision Clamping: Integrated gripping clamp secures and fine-adjusts rail position during laying or removal.

TNZYJ75 Technical Specifications at a Glance

The TNZYJ75 runs on a standard 18–38 L/min auxiliary circuit at 220 bar, so most 6–9 ton excavators drive it without hydraulic upgrades. At 476 kg it stays light enough for compact carriers, yet handles 43, 50, 60 and 75 kg/m rail profiles — covering virtually every international track standard on one attachment.

Engineered for Demanding Railway Environments

Built from high-strength alloy steel, the Rail Threader withstands the shock loads and abrasive conditions of daily track work. The hydraulic tiltrotator delivers smooth, proportional control for exact rail alignment, while the triple-clamp system — 310 mm finger clip, 176 mm mechanical clamp and 81 mm clamp opening — grips rail webs and flanges securely. Maintenance is simple: a hydraulic and lubrication check every 500 operating hours keeps the unit production-ready.

Where the Rail Transfer Guide Delivers Value

From new line construction to emergency repair, the Rail Threader turns a standard excavator into a dedicated rail-laying machine:

• Track installation: Threading and positioning new rails during mainline and siding construction

• Rail replacement: Extracting worn rails and guiding replacements into the sleeper seat

• Depot & logistics: Loading, unloading and staging rail stock in yards and storage areas

• Maintenance windows: Fast rail repositioning during limited skylight access periods
