Bolted Rail Clip — M12

CL3-12 Through-Bolt Crane Rail Clip

The CL3-12 is an M12 through-bolt crane rail clip designed as a bearing-type connection for light duty crane rail and light rail installations. It uses a circular cam mechanism to lock the clip body against the rail foot, providing secure lateral restraint while allowing future adjustment or rail replacement.

The clip body and cam can be hot-dip galvanized without reducing lateral resistance ratings, making the CL3-12 suitable for outdoor and corrosive environments. The clip top incorporates a vulcanized synthetic pressure block for rail retention and load absorption.

Installation uses a standard M12 hex bolt, nut and hardened washer. The modular pressure block can be replaced without replacing the entire clip top assembly, reducing long-term maintenance cost.

Rail Profiles the CL3-12 Suits

The CL3-12 is suited to lighter crane rail and light rail profiles where an M12 bolt configuration is appropriate. For heavier profiles requiring higher lateral load capacity, the CL4-16, CL4-20 or CLX series may be more suitable. Not sure which clip suits your application?

Where the CL3-12 is Used

The CL3-12 suits installations where an M12 through-bolt configuration is appropriate and where future rail adjustability or replacement is a consideration. As a bearing-type connection it is robust, cost-effective and simpler to install than welded clip systems.

Primary Use
Light duty overhead crane runways in workshops and light industrial facilities
Rail Type
Light crane rail (A45, A55) and light rail profiles from 10kg to 37kg
Installation Type
New installations and replacement works where bolt adjustability is required
Environment
Indoor and outdoor — clip body can be hot-dip galvanized for corrosive environments
Maintenance
Pressure block is replaceable without replacing the full clip top assembly

FAQ

CL3-12 Rail Clip: Common Questions

What is the CL3-12 crane rail clip used for?
The CL3-12 is an M12 through-bolt crane rail clip for light duty crane rail and light rail installations. It suits lighter rail profiles including A45, A55 and light rail sections from 10kg to 37kg where an adjustable, bearing-type bolted connection is required.
What bolt size does the CL3-12 use?
The CL3-12 uses a standard M12 hex bolt with nut and hardened washer. This is the smallest bolt size in the CL bolted clip range. For applications requiring higher load capacity, the CL4-16 (M16), CL4-20 (M20) or CLX series clips offer larger bolt options.
What is a bearing-type connection in a rail clip?
A bearing-type connection means the clip transfers lateral loads through direct contact between the clip body and the rail foot, rather than through friction. This makes bearing-type clips like the CL3-12 robust and reliable without requiring precise torque management, and allows the bolt to be re-tightened or replaced without recalibrating the connection.
Can the CL3-12 be hot-dip galvanized?
Yes. The CL3-12 clip body and cam can be hot-dip galvanized without reducing the lateral resistance rating of the clip. This makes it suitable for outdoor installations, coastal environments and other applications where corrosion protection is required.
How does the modular pressure block work?
The clip top incorporates a vulcanized synthetic pressure block that sits between the clip and the rail head. When the pressure block wears, it can be replaced without replacing the entire clip top assembly, reducing maintenance cost over the life of the installation.
How do I know if the CL3-12 is the right clip for my application?
The CL3-12 suits light duty applications with smaller rail profiles. If you have a heavier rail section, higher lateral loads or a larger bolt pattern specified, one of the CL4 or CLX series clips may be more appropriate. Send us your rail profile, application details and any drawings and we'll advise on the right clip type, size and spacing.
