The Hydraulic Rail Stretching Machine YLS-900I is a specialized device for rail tensioning, designed to address the critical need for seamless rail line construction and stress adjustment.
| Quantity: | |
|---|---|
Powered by a high-pressure hydraulic system, it delivers controlled, uniform stretching force to rails—eliminating gaps that cause noise, vibration, and premature wear. Unlike manual or mechanical stretchers, the YLS-900I ensures precision and safety, making it an indispensable tool for modern railway maintenance teams aiming to enhance track durability and passenger comfort.
• High Tensioning Precision: Millimeter-level control over stretching length, ensuring rail stress meets national standards (e.g., GB/T 18115).
• Powerful Thrust: Maximum stretching force of 900kN (90 tons), suitable for all standard rail grades (50kg/m to 75kg/m).
• Safety-Centric Design: Equipped with overload protection and emergency stop buttons, preventing rail deformation or equipment damage.
• Easy Adaptability: Adjustable clamping jaws to fit different rail profiles, reducing the need for multiple specialized tools.
The YLS-900I uses a 31.5MPa hydraulic system with a double-acting cylinder, enabling smooth, bidirectional movement (stretching and retracting). The system also includes a pressure gauge and relief valve, allowing operators to monitor and adjust force in real time—critical for avoiding over-stretching.
Constructed from Q345 high-strength steel, the machine’s frame can withstand heavy loads and impacts during outdoor use. All moving parts are coated with anti-corrosion paint, ensuring durability in rainy, snowy, or dusty environments (service life of 8–10 years under normal use).
The machine features a hydraulic hand pump (or optional electric pump for heavy-duty tasks) and a digital display for stretching length. Even in tight spaces (e.g., between sleepers), operators can easily control the device—reducing labor intensity and improving efficiency.
• Seamless rail line construction (joining rail segments into long, gap-free tracks).
• Rail stress adjustment (compensating for thermal expansion/contraction in seasonal temperature changes).
• Track maintenance (repairing rail buckling or gaps caused by long-term use).
• High-speed railway lines (requiring ultra-low vibration and gap-free tracks).
• Urban subway systems (reducing noise pollution in residential areas).
• Heavy-haul freight railways (handling high loads that exacerbate rail gap issues).
