Rail Clip for STS Crane

STS Crane Rail Clips

Product Overview

STS crane rail clips are critical components for fixing rails in ship-to-shore crane systems, ensuring stable crane operation and operational safety in port environments. The YB1313B, YB33, and YB55 series clamps differ in material, specifications, and application scenarios, catering to diverse rail fixing requirements for STS cranes.

Product Types and Features

YB1313B Series STS Crane Rail Clamp

Structure Composition: Comprises a four-bolt pressing plate base (material: Q345), four-bolt pressing plate (Q345), double-end studs M16X35 (8.8 grade Dacro), and flange face nuts M16 (8 grade Dacro).
Technical Parameters: Tightening force: 66KN; tightening torque: 200Nm (k=0.2).
Application Scope: Suitable for specific rail fixing in STS crane systems (rail models applicable as per project specifications).
Product Advantages: Q345 material ensures high strength and comprehensive performance, enabling the clamp to withstand heavy loads and maintain rail stability during STS crane operations.

YB33 Series STS Crane Rail Clips

Structure Composition: Includes a pressing plate base (Q235) and upper pressing plate (Q235 + rubber), forming a Y3-type rail clip assembly. Recommended bolts: GB5783-86 M16x40 (8.8 grade); nuts: ZN6177.1-LFT M16 (8 grade).
Technical Parameters: Tightening force: 66KN; torque: 200Nm (k=0.2).
Application Scope: Specifically designed for flexible fixing of A75 and A100 rails in STS crane systems, providing reliable rail stabilization.
Product Advantages: Q235 material offers cost-effectiveness for general applications, while the rubber-integrated upper plate enhances shock absorption, reducing rail impact and noise during STS crane operation.

YB55 Series STS Crane Rail Clamp

Structure Composition: Consists of a pressing plate base (ZG270-500) and upper pressing plate (ZG270-500), paired with bolts GB5783-86 M16X40 (8.8 grade Dacro) and nuts ZN6177.1-SLFT M16 (8 grade Dacro).
Technical Parameters: Tightening force: 66KN; torque: 200Nm (k=0.2).
Application Scope: Suitable for fixing A75 and A100 rails in STS crane setups, ensuring stable rail support under heavy-duty operations.
Product Advantages: ZG270-500 casting material delivers excellent mechanical properties, combining high strength and toughness to withstand harsh port environment loads in STS crane applications.

Technical Requirements

Bolt Tightening Specifications: All three clamp series require a 66KN tightening force and 200Nm torque (k=0.2) to ensure secure rail fixation and prevent loosening during STS crane operation.

Nut Coating Requirement: Nuts must be painted immediately after installation (within 24 hours) to prevent corrosion, maintaining clamp durability and safety in port environments.

Application Scenarios

Primarily used for rail fixation in STS crane systems, these clamps ensure stable rail alignment during container loading/unloading operations at ports, enabling precise and safe crane movement while enhancing operational efficiency.

Selection Guide for STS Cranes

High-Strength Applications: Choose YB1313B (Q345) or YB55 (ZG270-500) series for heavy-duty STS crane operations requiring robust load-bearing capacity.
Shock-Resistant Needs: Opt for YB33 series with rubber components to mitigate vibrations and noise in STS crane rail systems.

Adhere strictly to technical specifications for installation and maintenance to optimize clamp performance and ensure long-term reliability in STS crane operations.
