Heavy-Duty Crane Rail Fastening Systems Manufacturer | Custom Port Rail Solutions for QU70-QU120
Crane Rail Fastening System
Our crane rail fastening system is a highly-reliable, heavy-duty rail solution for modern industrial facilities. It relies on post-installed chemical anchoring and Belleville disc-spring structures. It can compensate pre-load loss under heavy-duty vibration conditions, prevents bolt loosening, and achieves reliable fixing of crane rails on concrete foundations.
And it is widely used in ports, shipyards, steel mills and large-scale industrial plants. Its performance directly impacts the operational safety, maintenance costs and long-term service reliability of crane equipment. The crane rail fastening system is one of our core products. We can provide complete solutions covering crane rail clips, steel base plates, rubber rail pads, anchor bolts and all other rail fasteners suitable for heavy-duty applications in ports, mines, railways, crane rails, etc. Customization is available for all crane rail fasteners. And these products can be supplied to distributors worldwide.
Core Functions of Our Crane Rail Fastening System
Our crane rail fastening system shall deliver well balanced performance across four core functions:
Vertical restraint:
It prevents rail uplift under dynamic wheel loads
Lateral guidance:
It resists lateral forces exerted by cranes to keep track gauge stable
Longitudinal elasticity:
It enables controlled rail movement for thermal expansion and contraction
Vibration damping:
It mitigates fatigue loads transferred to rails, bolts and supporting structures
Crane Rail Fastening Systems We Supplied
We are a specialist supplier of crane rail fastening systems. We supply complete fastening solutions compatible with QU70, QU80, QU100, QU120 and other crane rail profiles. Please see the drawings below for our designed fastening systems of QU80 and QU100 rails for our clients. Customization is available for all crane rail fasteners. Feel free to contact us.
1. Our QU80 Crane Rail Fastening System
Below is our QU80 crane rail fastening system, designed for the Wuhan Xingang Sanjiang Port Terminal Project. It is purpose‑built for container RTG (rubber‑tyred gantry crane) track applications on concrete yards. It can serve as a replacement for GANTREX MK6-RF-130, delivering equal or superior operational performance. The system consists of clip assemblies, full-length steel-reinforced rubber pads, double-layer levelling plates, M24 U-shaped pre-cast anchor bolts and other high-strength fasteners, etc. It restricts lateral rail movement, permits longitudinal thermal expansion and contraction, and withstands heavy loads and lateral impact.
