Okrugli čelični lanci sa kratkim karikama za produženo podizanje tereta — Bezbednost — Deo 1: Lanci za priveznice srednje tolerancije klase 10X

Round steel short link chains for extended lifting purposes — Safety — Part 1: Grade 10X medium tolerance sling chains

Apstrakt

This document specifies the requirements for medium tolerance sling chains of grade 10X for the use primarily in chain slings,
assuming a nominal stress of 1 000 N/mm2 related to the cross-sectional area of both legs for the respective nominal diameter at the
specified minimum breaking force.
The range for the nominal diameter extends from 4 to 32 mm.
Sling chains according to this document are electrically welded, round steel short link chains with a nominal pitch pn = 3 × dn, heat
treated and tested. Permissible welding processes are flash welding, resistance butt welding and friction welding.
These sling chains are designed for use in a temperature range from -40 °C to +380 °C.
The sling chains are generally surface painted by the manufacturer for easy identification and corrosion protection. At the customer's
request, the surface condition is non-coated. Both characterise the finished condition.
NOTE The term in the title "extended use" implies the following differentiation criteria in relation to the sling chain 10X:
- Extension of the operating temperature range from -40 °C up to +380 °C
- The higher level of impact energy means greater resistance to unexpected shock loads
- A qualified evidence of relative resistance to stress corrosion cracking
