Daxara & Erde Trailer Information

Erde & Daxara TrailerTo ensure trouble-free use of your trailer we hope you will find the following information useful.

Please let us know if you have any comments, experiences or any information we could add to this page to help others.


On the drawbar, all DAXARA & ERDE trailers are equipped with a 50mm ball coupling with safety catch, which prevents the trailer becoming detached.

COUPLING AND UNCOUPLING OF TRAILER, lift the handle attaching the coupling to the towball at the same time as compressing the locking trigger on the handle and lift from the towball or place over the towball. It is possible to install an anti theft device that locks the coupling and provides added security. This is a recommended optional extra, please see the accessories available for your model of trailer (For details click your make of trailer – Erde or Daxara.)

The towing vehicle should be fitted with a towing bracket of a recognised standard. 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 the towball is 50mm diameter.

For additional security a safety chain is fitted as standard. This should be secured to the towing bracket at all times when towing, so that in the event of the trailer uncoupling the trailer will still be attached to the towing vehicle. (UK Reg. 1995).


      Very Important
Road trailers must be kept in a roadworthy 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 DAXARA and Erde trailers, it is important that the unit should be checked annually. After assembly and after the first 60 miles, check the tightness of a nuts and bolts of the following main parts: * wheels * axle * drawbar * coupling head * mudguards * lighting.


The wheel hubs including bearings are pre-greased for life. Therefore 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 or axle are immersed in salt water.

      Very Important
All loads should be evenly spread inside the trailer. For your own safety it is important that the trailer is not over loaded, the suspension units and tyres are designed to carry the trailers’ maximum gross weight which is marked on the identification plate on the trailer.

It is an offence to load the trailer to more than its marked gross weight


Inflation pressure should be checked regularly to avoid any risk of abnormal wear and punctures.

If heavily loaded or for long trips, it is necessary to increase tyre pressures by 0.50 bar (7psi).

Option: a spare wheel and fitting kit is available and is highly recommended for safety and convenience. (For details click your make of trailer Erde & Daxara

Total gross trailer weight of an unbraked trailer includes the weight of the trailer and the load. The maximum legal gross trailer weight of an unbraked trailer is 750kg or 50% of the kerb side weight of the towing vehicle. It is an offence to load the trailer to more than its marked gross weight


Gross trailer weight or maximum authorised mass (MAM): These refer to the total weight of the trailer including its maximum payload. It is the weight marked on the trailer specifications plate and must not in any circumstances be exceeded.

Unladen weight: This is the weight of the trailer without payload. This can vary from catalogue weight due to accessory options and should always be checked on a certified weighbridge.

Payload: This is the weight of the load that the trailer is permitted to carry and is the GROSS TRAILER WEIGHT minus the UNLADEN WEIGHT. If there is any doubt, us a weighbridge.

Trainweight: This is the Gross TOWING VEHICLE weight plus the Gross TRAILER WEIGHT

Kerbside Weight: The kerb weight of the towing vehicle is the weight of that vehicle including all fluids with a full tank of fuel and carrying all spares and tools which the vehicle is usually supplied but without driver, passenger or luggage.

Wheeltrack: The horizontal distance between the centre lines of the wheel tyre treads.

Nose Load/Hitch Load Stability: A trailer must always be towed in a stable condition. To achieve this, the trailer must exert a downwards load on the towball of the towing vehicle. This will vary from trailer to trailer and should be obtained from the supplier. It is likely to be 50 to 75 kg. This is measured with a spring balance or scales supporting the full weight of the hitch at the towing point and as the towing height. Care must be taken when loading the trailer not to change the nose load. Maximum allowable nose load is given by the (towing) vehicle manufacturer.

Maximum permissible length: The normal maximum permissible length of a trailer is 7 metres excluding the drawbar and coupling.

Maximum permissible width: 2.55 metres.Note: In the case of length, width and height, these are overall dimensions including linchpins, hinges, etc., it is possible to increase these dimensions in special circumstances
