Double Flange Crane Wheel
The double-flange crane wheel features raised rims on both sides to deliver superior anti-derailment protection and lateral stability under heavy loads and uneven tracks. Available in forged and cast options with tailored heat treatment for long wear life.
Product Overview
The Double-Flange Crane Wheel is a wheel designed for gantry, bridge and heavy-duty crane travel applications. With flanges on both sides (typical flange height 25–30 mm) and a tread engineered to sit 20–30 mm wider than the rail head, the SL wheel improves tracking, reduces lateral movement and significantly lowers the risk of derailment in demanding operating conditions.
Typical Applications
Gantry & bridge cranes — main travel wheels for heavy lifting and long-span applications.
Steel mills & ports — handles very large static and dynamic loads where load sway creates lateral forces.
Mining transport — works on rough or uneven track conditions, improving stability in curves and gradients.
Specialized rail applications — where anti-derailment and lateral guidance are required (subject to railway standards and certification).
Key Features
Dual anti-derailment protection: Raised flanges on both sides constrain wheel position to minimize derailment risk under side loads and load sway.
High lateral stability: Distributes lateral forces on sloped or uneven tracks to reduce sway, side-slip and overturn risk.
Standardized tread geometry: Tread width designed to match common rail heads (20–30 mm wider than rail top) for reliable seating.
Material flexibility: Supplied in 60# carbon steel, 65Mn, or 42CrMo; available in forged or cast blanks with customized heat treatment.
Durable tread hardening: Induction/high-frequency quenching available—typical hardened layer 15–20 mm—to extend wear life.
Factory inspection: Delivered with UT (ultrasonic) inspection, hardness testing and metallographic records on request.

Selection Recommendations
By load: Standard operatings — 60# carbon steel; heavy or impact-prone services — 42CrMo forged with deeper tempering.
By track condition: For complex track geometry or pronounced lateral forces, choose double-flange wheels combined with lateral guide wheels.
By environment: Corrosive environments (coastal, chemical) — specify protective coatings or corrosion-resistant materials.
Acceptance criteria: Require UT inspection report, hardness values and metallographic certificate from supplier.

FAQs
Q : Is double-flange crane wheels always better than single-flange?
A:Double-flange offers superior lateral restraint and anti-derailment for heavy side loads and uneven tracks, but it can be slightly heavier and more complex. Choose based on load, speed and track geometry.
Q:Why is tread hardening depth important?
A: Hardened depth controls wear life and fatigue resistance of the tread. Heavy-duty applications typically need 15–20 mm or deeper hardened layers for longer service life.
