Radiant Precicom spring buffers absorb kinetic energy at the end of crane and conveyor travel, protecting structure and equipment from impact damage. Manufactured with IS 4454 compression springs housed in mild steel or cast iron bodies, they are engineered for long, low-maintenance service lives.
Technical Specifications

Typical Applications
Manufacturing Process
Spring Wire / Bar Incoming
Grade to IS 4454 Gr1/Gr2 or EN42/EN45; incoming hardness and dimensional check
Spring Coiling / Housing Machining
Compression spring coiled to calculated free length and pitch; housing turned on CNC lathe
Heat Treatment & Shot Peening
Springs stress-relieved at 220–250°C; shot-peened to improve fatigue life
Load-Deflection Testing
100% spring load-deflection curve tested on spring testing machine; result vs. design curve
Assembly
Spring assembled into housing; pre-load set; end plates fitted and pinned
Final Inspection & Marking
Compressed height, free height, load at test length verified; part marked with lot number
