Radiant Precicom rail clamps are designed to secure overhead and gantry cranes against wind and storm loads, as well as provide positive parking restraint during maintenance. Each clamp is hardened to specification and proof-load tested, ensuring dependable performance in the most demanding material-handling environments.

Typical Applications
Manufacturing Process
Material Incoming
EN8/EN24 bar stock received with MTC; PMI/XRF verification; hardness sampling per heat
Rough Machining
Turning/milling clamp body to within 1mm of finish dimensions; stress relief if required
Heat Treatment
Induction hardening of jaw contact surfaces to HRC 45–52; hardness verified after quench & temper
Finish Machining
Final CNC turning/milling to drawing tolerance (±0.05mm on contact surfaces)
Surface Treatment
Shot blasting Sa 2.5 + epoxy primer 40µm + finish coat 60µm, or hot-dip galvanising per IS 2629
Functional Testing
Load test to 1.5× rated clamping force; jaw travel and spring-back checked; dimensional report issued
