2 short ratchet straps with SS ratchet, they also had plastic coated
hooks. I ditched them for SS hooks S shape, with plastic tubing to close
off one end and keep it on the strap (like plastic tubing on a gaff, if
that makes sense? )
This is what I replaced with.. bit of over kill but as it turns out they are heavy enough that can simply swing into place rather than reach down and hook... "work hard at being lazy".. accidentally this time
This is the full WoF for light trailer hitches
Mandatory equipment
1. A trailer with a laden weight ( http://vehicleinspection.nzta.govt.nz/virms/in-service-wof-and-cof/general-trailers/towing-connections/light-trailer-drawbar-and-kingpin#note2" rel="nofollow - Note 2 )
of 2000kg or less without a compliant breakaway brake, except for the
following trailers, does not have a safety chain or cable:
- a trailer designed for armament purposes by the New Zealand Defence Force.
- a trailer pump for fire fighting purposes.
2. A trailer with a laden weight ( http://vehicleinspection.nzta.govt.nz/virms/in-service-wof-and-cof/general-trailers/towing-connections/light-trailer-drawbar-and-kingpin#note2" rel="nofollow - Note 2 )
between 2001kg and 2500kg (where the vehicle inspector is able to
determine the laden weight) that does not have a compliant breakaway
brake:
a) is not fitted with two safety chains that cross each other when connected, or
b) has chain links with a material
cross-section less than 7.1mm, or there is no evidence that each chain
has a breaking strength of at least twice the laden weight of the
trailer ( http://vehicleinspection.nzta.govt.nz/virms/in-service-wof-and-cof/general-trailers/towing-connections/light-trailer-drawbar-and-kingpin#note3" rel="nofollow - Note 3 ).
Condition
3. The drawbar or drawbar mounting (or kingpin or kingpin mounting):
a) is not securely attached, or
b) has a bolt, nut or pin that is missing or significantly corroded or damaged, or
c) has corrosion damage ( http://vehicleinspection.nzta.govt.nz/virms/in-service-wof-and-cof/general-trailers/towing-connections/light-trailer-drawbar-and-kingpin#note1" rel="nofollow - Note 1 ) within 150mm of a mounting point, or
d) is cracked or distorted.
4. The drawbar coupling (or kingpin):
a) is not securely attached, or
b) is not mounted in accordance with manufacturer’s specifications, or
c) is worn beyond the manufacturer’s specifications, or
d) is significantly corroded, distorted or cracked, or
e) has a nut or locking pin that is missing or significantly corroded.
5. A safety chain or cable (including any welded joint, securing bolt or shackle):
a) is not securely attached to the drawbar, or
b) is welded to the drawbar, and
i. there is no clear evidence of weld penetration, or
ii. the weld metal has not been applied in accordance with good trade practice, or
iii. there is no evidence that the chain can be welded without reducing its strength, or
iv. the weld is significantly corroded, has deteriorated or is cracked.
c) is significantly corroded, distorted or cracked, or
d) has a bolt or shackle that is missing, significantly corroded, distorted or cracked, or
e) appears to be too weak to withstand a
load of about twice the likely maximum laden weight (as far as can be
reasonably estimated by the inspector) ( http://vehicleinspection.nzta.govt.nz/virms/in-service-wof-and-cof/general-trailers/towing-connections/light-trailer-drawbar-and-kingpin#note3" rel="nofollow - Note 3 ).
Note 1
Corrosion damage is where the metal has been eaten
away, which is evident by pitting. The outward signs of such corrosion
damage is typically displayed by the lifting or bubbling of paint. In
extreme cases, the area affected by the corrosion damage will fall out
and leave a hole.
Note 2
Laden weight means the weight of the trailer and its load, if any,
for the time being carried. A vehicle inspector may be presented with a
trailer (usually unladen, such as a boat, car or horse trailer) that has
a laden weight below 2000kg, but that is likely to have a laden weight
exceeding 2000kg when it carries its normal load. In such a case, the
vehicle inspector should make the vehicle operator aware, for example by
putting a note on the checksheet, that the trailer may not comply with
safety chain or shackle requirements when the trailer carries its normal
load.
Note 3
A safety chain or shackle may be marked as complying with a standard
and with a chain designation size that equals the maximum laden weight
of the trailer, for example, with 25 or 2500 which denotes 2500kg. This
means the chain is suitable for a trailer with a laden weight of up to
2500kg as the standard has already taken into account the required
breaking strength.
