USE AND MAINTENANCE OF ERDÉ TRAILERS 153
These trailers are light duty luggage road trailers and are not suitable for industrial use.
1) COUPLING
On the drawbar: all ERDÉ trailers are equiped with a 50 MM ball coupling with safety
catch, which prevents the trailer becoming detached.
COUPLING AND UNCOUPLING OF TRAILER:
Proceed as follows: lift the end of the handle attaching the coupling to the towball,
operating at the same time the locking trigger on the handle.
Option: It is possible to install an antitheft device that locks the coupling and provides
added security. This is a recommended optional extra.
On the car : towing brackets of a recognised standard should be fitted. Preferably these
should comply with the relevant British and international standards (UL standards
AU113 and 114 and international standards ISO1103 and 3553). European standard for
towball is 50 MM diameter. (Tow bars 400 to 600 kgs sufficient for all ERDÉ trailers)
For additionnal security a safety chain is fitted as standard. This should be secured to
the towing bracket at all times, so that in the event of uncoupling the trailer will still be
attached to the towing vehicle. (UK Reg.1995)
2) MAINTENANCE
VERY IMPORTANT
Road trailers must be kept in a road-worthy condition and it is a legal requirement that
all trailers be maintained and comply with the different regulations. While there is very
little maintenance required on ERDÉ trailers, it is important that the unit should be
checked annually.
After assembly and the first 60 miles, check the tightness of all nuts/bolts of the following
main parts :* wheels
* axle
* drawbar
* coupling head
* mudguard
* lighting
3) HUBS
The wheel hubs including bearing are pregreased for life. No greasing needs to be
done. When necessary, replacement hubs and bearing are available as spares. Do not
put trailer in sea water, damage may occur if hubs/axle immersed in salt water.
4) LOADING
VERY IMPORTANT
For your own safety it is important that the trailer is not over loaded. The suspension
units and tyres are designed to carry the following maximum weights.
MAXIMUM LOAD PERMISSABLE
- MODEL ERDÉ 153
390 Kilos
It is an offence to load the trailer to more than its marked gross weight.
The responsability for loading the trailer must be that of the user and as a guide, the
following table will give some typical loads :
QUANTITY/LOAD
APPROXIMATE UNIT WEIGHT
TOTAL WEIGHT
4 suitcases
25 Kilos
100 Kilos
3 tents
18 Kilos
80 Kilos
6 rucksacks
40 Kilos
240 Kilos
70 logs
3 Kilos
210 Kilos
To obtain good road holding, it is important that the load is loaded with
sufficient weight on the drawbar (5% to 10% of the load). A load on the rear
will cause pitching of the trailer. Once loaded, ensure that the trailer drawbar
is always kept horizontal or slightly on its nose, towards the car. If this is not
the case, change the height of your bracket by using a drop plate which will allow you to
change the height of the coupling.
If fitting a drop plate, refer to drop plate instructions.

5) TYRE PRESSURE
Inflation pressure should be checked regularly to avoid any risk of abnormal wear and
punctures.
350x8 wheel : 2,5 bar/36 LBS per SQ inch - 480x8 wheel : 2,5 bar/36 LBS per SQ inch
400x10 wheel: 3,5 bar/50 LBS per SQ inch - 500x10 wheel: 3,5 bar/50 LBS per SQ inch
135x13 wheel: 2,5 bar/36 LBS per SQ inch - 145x13 wheel: 2,5 bar/36 LBS per SQ inch
If heavily loaded, or for long trips, it is necessary to increase tyre pressure by 0,50 bars.
Please note : all trailers wheels and tyres fitted to these trailers must be pneumatic and
capable of taking the maximum gross unit weight. They must
be rated to 60 MPH and maintained at the correct tyre pressures. As with
motor vehicles, it is illegal to drive with a mix of radial and crossply tyres on
the same axle. Option: a spare wheel and fixing kit is available and is highly
recommended for safety and convenience.
6) ELECTRICAL CONNECTIONS
The electrical fitments are based on the European standars system equiva-
lent BS 149A.
Contact Block N° 1 - Left indicator
(Yellow or orange wire)
Contact Block N° 2 - Fog lamp
(Blue wire)
Contact Block N° 3 - Earth
(White wire)
Contact Block N° 4 - Right indicator
(Green or violet wire)
Contact Block N° 5 - Right tail + N° plate lights
(Brown wire)
Contact Block N° 6 - Stop lights
(Red wire)
Contact Block N° 7 - Left tail + N° plate lights
(Black wire)
7) REGISTRATION
The number plate of the trailer must be identical to the towing vehicle.
The size of the number plate should be as per BSI standard 520 MM.
Hand written number plates are not acceptable and are illegal.
(Total gross weight of an unbraked trailer includes the weight of the trailer
and the load). It is an offence to load the trailer to more than its marked
gross weight.
TRAILER LAW
The following brief explanation of legislation governing the construction and use of trailer is
given as a guide.
Because legislation and regulation is subject to interpretation, we cannot be held reponsible,
this is not a statement of regulations, only a guide if you are in any doubt you should consult
the DEPT OF TRANSPORT.
THE TRAILER
TOWING WEIGHTS
MGVS (Maximum Gross Vehicle Weight) - WEIGHT OF T LOAD.
1 - MGVW of a trailer fitted with over-run brakes
3 500 Kgs
2 - MGVW of an unbraked trailer must not exceed
750 Kgs
or 50% of the kerb weight of the towing vehicle, whichever the lower.
SUSPENSION:
All trailers must be fitted with a suspension device on all wheels.
COUPLING :
Either a ball (50 MM) or an eye type may be used.
Braked trailers must be fitted with auto-reverse brakes and the coupling must be
hydraulically damped. This is now a requirement but some older trailers may be exempt.
NUMBER PLATE :
A rear number plate must be fitted and must be yellow reflecting
with the same registration number as the towing vehicle. The plate and numbers must
conform to BSAU145A. They cannot be hand written.
WHEELS AND TYRES :
All trailer wheels and tyres for road use must be pneumatic
and capable of carrying MGVW. They must be rated up to 60 MPH and be maintened at
the correct pressure. As with cars, it is illegal to mix radial and crossply tyres on the
same axle.
MUDGUARDS :
Mudgards must be fitted to all wheels, if adequate protection is not
given by the body of the trailer.
DIMENSIONS :
* Max length of 2 or 4 wheel trailers
7 metres
* Max length of 4 wheel trailers
12 metres
(Providing the max gross weight of the towing vehicle exceeds 3500 Kgs)
* Max length of trailer and vehicle
12 metres
* Max width of trailer or vehicle
2,3 metres
* Max width, if towing vehicle MGVW exceeds 3500 Kgs
2,5 metres
BRAKES :
When brakes are required on the trailer they must be fitted to all wheels.
LIGHTS AND PROTECTORS :
Trailer must be fitted with lights and reflectors. Bulbs
and reflectors must be 'E' or 'e' marked.
MAINTENANCE :
it is requirement that all trailers are maintained and used in a
roadworthy condition and comply with the various regulations at all times.
LABELS:
the maximum gross trailer weight of an unbraked trailer (up to
750 Kgs MGVW) must be marked on the trailer.
THE TOWING VEHICLE
The maximum gross trailer weight of an unbraked trailer (in the U.K.) is
750 Kgs or 50 PCT of the kerb weight of the towing vehicle.
The maximum gross weight of both braked and unbraked trailers should not however
exceed those stated in your vehicle hand book or the weight rating of your tow bracket.
TOW BRACKET
A towing bracket which conforms to the British standard AU24/1989, should be fitted to
the towing vehicle.
LIGHTING
Trailer lights are generally connected to the towing vehicle by means of a 12N plug and
12S socket. It is recommended that these are wired to BS AU149A.
If the towing vehicle is fitted with rear fog lights, a CUT-OUT is advisable.
A means of audible or visual warning is required to be fitted in the towing
vehicle to detect such failure of indicator lamp.
Care should be taken in stowage of the 12N and 12S plugs when not
connected, to avoid unnecessary damage.
USING THE TOWING VEHICLE AND TRAILER AS A COMBINATION
A trailer being towed by a passenger vehicle or commercial vehicle less that
7,5 tonnes GVW, must conform to the following maximum speeds:
60 MPH on motorways
60 MPH on dual carriageways and roads
50 MPH on other roads
Unless lower speeds are in operation.
A trailer must not be towed in the outside lane of a 3 lane road or motorway
LOADS
It is critical to your safety that trailers are never overloaded beyond their
design capability in such a way as to make it unsafe.
All loads should be evenly distributed and secured.
