13 Stock crate certification
It is important that stock crate retention is correctly certified to the appropriate standard. This technical bulletin provides explanations of different types of stock crates (fitted to a vehicle with a GVM of 6000 kg or more) their attachments, how to identify them, and how to identify their certification.
Stock crate attachment types
There are three common ways that stock crates are attached to heavy motor vehicles:
The crate attachment is easy to see as the J-hooks sit on the outside (Figure 13-1-1).
Figure 13-1-1. J-hook stock crate
This must be certified to 5413.
A stock crate and vehicle constructed as one integral assembly, usually without a rigid chassis, with the wheel and axle assemblies , suspension and steer dolly (in the case of a full trailer) attached directly to the crate assembly. The stock crate fits directly to the chassis and there are no coaming rails or tie rails. (Figure 13-1-2).
Figure 13-1-2. Monocoque stock transfer vehicle
This must be certified to NZS5413.
Another common attachment is the deck-mounted stock crate. There are no external attachments and the fitment looks very similar to monocoque except that the crate sits on a deck which is visible with a coaming rail and general fitment of load anchorages and tie rails (Figure 13-1-3).
Figure 13-1-3. Deck-mounted stock crate
This crate must be certified to NZS5413 and the deck mounting point must be certified to NZS5444.
Requirements for certification of deck mounted stock crates.
The stock crate is not a vehicle therefore the actual crate bolt mountings and bolts cannot be certified with an LT400. The design can be certified with a design certificate and a plate or label attached to the stock crate.
The design certification for the stock crate anchorage is catered for with an engineer’s design certificate and the engineers certificate will be held on file by the stock crate manufacturer.
The stock crate identification plate or label needs to have all of the following information:
- Company name
- Serial number
- Date of manufacture
- Restraint capacity load
- Restraint capacity individual
- Number per side
A certificate of fitness inspector can be satisfied in regard to the certification of the stock crate bolted mountings if a plate or label providing all the information above is attached to the crate and there is a separate load anchorage certification plate fitted to the vehicle to cover the deck mounting points used to secure the stock crate.
Sample stock crate plate design
- Any vehicles inspected after 1/11/2016 that do not meet the requirements but are fit for purpose (inspector has completed a detailed visual inspection and is confident that the anchorage points are in good condition) may be passed for CoF but must have certification completed (in line with this technical bulletin) before next CoF. Notes must be recorded showing the completion of this inspection and actions needed to be taken before next CoF.
- Any vehicles presented for inspection 1 year after 1/11/2017 will not pass for CoF without correct certification.
- All vehicles presented for first time entry compliance must meet these requirements for stock crate/load anchorage immediately.
