CL4-16 Through-Bolt Crane Rail Clip

The CL4-16, also written CL416, is an M16 through-bolt crane rail clip designed as a bearing-type connection for light to medium duty crane rail and 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 M16 bolt gives the CL4-16 higher load capacity than the CL3-12, making it suitable for a broader range of crane rail and standard rail profiles.

The clip body and cam can be hot-dip galvanized without reducing lateral resistance ratings, making the CL4-16 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 M16 hex bolt, nut and hardened washer, and the modular pressure block can be replaced without replacing the entire clip top assembly, reducing long-term maintenance cost. Inform Rail holds CL4-16 stock in Brisbane and Cairns for fast dispatch to projects across Australia.

Rail Profiles the CL4-16 Suits

The CL4-16 is suited to a wide range of crane rail and rail profiles where an M16 bolt configuration is appropriate. For heavier profiles requiring higher lateral load capacity, the CL4-20 or CLX series may be more suitable.

Where the CL4-16 is Used

The CL4-16 suits installations where an M16 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.

FAQ

CL4-16 Rail Clip, Common Questions

What is the CL4-16 crane rail clip used for?
The CL4-16, also written CL416, is an M16 through-bolt crane rail clip for light to medium duty crane rail and rail installations. It suits lighter rail profiles including A45 and A55 crane rail, light rail sections from 10kg to 37kg and 41kg standard rail where an adjustable, bearing-type bolted connection is required.
What bolt size does the CL4-16 use?
The CL4-16 uses a standard M16 hex bolt with nut and hardened washer. For applications requiring lighter duty, the CL3-12 (M12) is available. For higher load capacity, the CL4-20 (M20) or CLX series clips are recommended.
What is a bearing-type connection in a rail clip?
A bearing-type connection transfers lateral loads through direct contact between the clip body and the rail foot, rather than relying on bolt preload and friction at the interface. Because the load path is bearing rather than friction, hot-dip galvanizing, oil or grease on the contact surfaces does not reduce the lateral resistance rating of a clip like the CL4-16. Bolts are still installed to the torque specified in the product sheet, but the clip's rated capacity does not depend on maintaining that preload.
Can the CL4-16 be hot-dip galvanized?
Yes. The CL4-16 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.
Where can I buy CL4-16 rail clips in Australia?
Inform Rail stocks CL4-16 clips in Brisbane and Cairns and supplies them Australia-wide, from single clips to full project quantities with no minimum order. Send your rail profile and quantities through the Inform Rail Easy Quote form or call (07) 3339 3085 for a fast supply price.
How do I know if the CL4-16 is the right clip for my application?
The CL4-16 suits light to medium duty applications across crane rail, light rail and standard rail profiles. For heavier profiles with higher lateral load requirements, the CL4-20 or CLX series may be more appropriate. Send Inform Rail your rail profile, application details and any drawings for advice on the right clip type, size and spacing.
