NZS 5446:2007

Heavy vehicle towing connections - Drawbeams and drawbars

This document has been re-assessed by the committee, and judged to still be up to date.

Establishes design, manufacture, installation, testing, maintenance, repair, and certification criteria necessary to ensure that a secure connection can be maintained between towing vehicles and drawbar trailers. Although primarily covering applications incorporating pin or hook type couplings, this Standard also applies to other types of couplings covering both rigid and hinged drawbars.
