Trolley Rail & Short Rail Systems for STS Cranes
Precision-engineered rail solutions for ship-to-shore cranes, designed to ensure smooth trolley rail operation and long-term reliability.
What Are Trolley Rail and Short Rail?
Trolley rails form the running track on STS crane booms and girders, enabling the trolley to move back and forth during container handling. Short rails are specialized connections at the boom hinge joint, bridging the boom rail with the girder rail while allowing the crane to boom up. Engineered for strength and durability, these rails reduce shock, vibration, and wear, ensuring smooth crane operation.

Key Features of Trolley Rail Systems
- High-Grade Steel Profiles – Typically manufactured in A75 or A100 profiles using alloy steels such as 42CrMo4 for maximum strength and durability.
- Secure Installation – Rails mounted on resilient pads and attached with clips, clamps, or bolts for stable alignment.
- Shock-Resistant Short Rails – Reinforced design at boom hinge joints to withstand impacts as the trolley passes between boom and girder.
- Custom Machining – Precision machining available to match specific crane designs and operational requirements.
Materials for Trolley Rails & Short Rails
Our trolley rails are typically produced in A75 and A100 profiles, using high-grade alloy steels such as 42CrMo4 to deliver superior wear resistance and strength.
All materials undergo strict heat treatment, chemical analysis, and hardness testing to ensure stability under heavy crane loads.
By combining premium steel with precision machining, we guarantee long service life, reduced vibration, and consistent performance in demanding port environments.
Tailored Short Rail Solutions
Reinforced Wide-Type Short Rails – Designed for single-box girder crane systems, offering maximum durability.
Standard-Type Short Rails – Optimized for dual-box girder cranes with proven stability.
Flexible Installation Options – Fixed with bolts, clamping plates, or fully welded ends to suit project needs.
Patented Vibration Reduction – Our design improves operator comfort and reduces mechanical wear by minimizing vibration transfer.
