About the Vehicle


Q1. Which is the best truck to buy for a horsebox?

A. In our experience most of the commercial vehicles available today are suitable for our use. More important is the general condition of vehicle and the use it has had in its previous life. If you have a preference for a particular vehicle don't go forward with blinkers!
You may pass a better condition, better value vehicle of another manufacturer. Don't be afraid to ask for a test drive. Check that you can achieve a comfortable and safe driving position.
Remember that a recent test certificate doesn't mean the vehicle is fault free, but it does go part way. If you are not a qualified mechanic always have the vehicle checked out by somebody who is!

Q2.
What do the model numbers on the chassis cab mean?

A. The first numbers indicate the vehicle weight, the second the bhp. of the engine.
Examples. Cargo 0813. The 08 is the code for 7.5 ton.
The 13 represents 130 bhp engine size.
814 Mercedes. = 7.5 ton with a 140 bhp engine.
This number system is adopted by most of the commercial vehicle manufacturers.

Q3. Which size engine should we go for?

A. As horseboxes are usually driven carefully, at first sight it may seem unnecessary to have a large engined vehicle. However, as we are now using motorways more frequently, the need to cruise without engine strain or excessive noise is of paramount importance. This can only be achieved with a large engined unit. If you mainly use the box for short local trips a small engine unit can be a more economical proposition.
The latest 7.5-ton vehicles can have engines as large as 160 bhp. It seems only a few years ago the Bedford TK was king.
It's engine produced only 90 bhp !
As a general rule we would suggest that the larger engine the better, even if your use may dictate a smaller unit, think of the resale value!
If we were buying a 7.5 ton vehicle for a customer we would not look at anything under 130 bhp.

Q4. What does 7490 KG on the plating certificate mean?

A. The GVW (gross vehicle weight) shown on the plating certificate is the Maximum weight the vehicle can be when fully loaded.

Q5. I have heard of people being stopped by the police and then fined for overweight. How can I avoid this happening to me?

A. You should be aware of the unladen weight of your vehicle. This can be easily established by taking the unit to a Public Weighbridge.
Armed with the unladen weight, now add the weight of your load. (Horses, people, tack, dog, sandwiches and mother-in-law).
This total should not exceed the GVW.
For accuracy consider two trips to the weighbridge.
The first unladen and the second fully loaded.
The few pounds this will cost you could save a fine of over £1000.

Q6. Can I be overweight on either axle?

A. It is possible to be prosecuted if overweight on either axle. The plating certificate will show different limits against each axle.
Axle 1 is the front and on a 7490 KG vehicle will be around 3000 KG.
Axle 2 is the rear, and will be around 5000 KG.
To be sure you are legal it is wise to have 3 weighs on the weighbridge.
1). Front wheels on.
2) All wheels on.
3). Rear wheels on.
With the weighbridge ticket you can now compare with the figures on the plating certificate.
The responsible horsebox manufacturer has always been aware that the position of the horses in relation to the rear axle is crucial in achieving a properly balanced vehicle.
We have recently discussed this situation with a customer who is a magistrate. By coincidence he had just fined a commercial operator £600 for being overweight on the front axle.
You have been warned!

Q7. Do I need to use the tachograph?

A. If you are using the box for private purposes
you are not required to use the tachograph.
back to top



Q8. Do I need an Operators Licence for my box.

A. All commercial vehicles over 3500 KG when being used commercially are required to have a current Operators Licence.
If you are using the box for private purposes you are exempt.
Beware. If you are transporting any load for reward, ie. a producer taking ponies to a show, a livery yard owner taking his clients to a show, you must have a current Operators Licence.
In addition the vehicle must not be taxed as private heavy goods, and must be run on a tachograph. Remember that if involved in an accident and it was shown that you were in contravention of any of the above it is unlikely that your insurance would be valid!

About the Container


Q9. Exactly what is a "Coachbuilt" box?

A. The term "Coachbuilt" is seen in many horsebox adverts.
It is generally thought that a new build on either a new or pre used chassis is a "Coachbuilt".
However, the established manufacturers would argue that a traditionally constructed box based on a steel or aluminium frame, (or in days of old a hardwood frame, usually ash), is a true "Coachbuilt". The frame is clad externally with a smooth sided sheet.
Aluminium being the preferred modern material.
Most new boxes are today constructed of a GRP faced board.
Although the manufacturers of these units may disagree, we can't accept these as "Coachbuilt".

Q10. I have been told that a conversion is inferior to a new build.
Is that correct?

A. The obvious difference is that with a conversion we are working from a
box van that is pre-used.
A good condition ex-commercial GRP van can be converted to the same level as a new GRP build. (At a fraction of the cost of the new material). There is an obvious advantage in starting with new materials, but for the average DIY builder working in the open, having a waterproof "shed" from the outset is not only saving money but enables the job to continue "indoors" during bad weather.

Q11. What is GRP or Glasonite?

A. Glasonite is the trade name for GRP board.
The boards are available in single sheets up to a maximum
size of 40'-0" long x 14'-0" high.
They are constructed from a core of plywood (usually ¾" or 18mm thick), faced both sides with a skin of fibreglass. The external skin is usually a smoother finish than the interior. (But not to the fine finish of aluminium).
For many horsebox manufacturers these sheets represent the most economical way of constructing the external wall of a container. Once lifted into position it is a simple matter to fix with either bolts or rivets, cut out the openings for windows and door, the side is ready!
The main disadvantage of such a construction is the lack of lateral strength, and the vulnerability of the board to dampness ingress.
Any damp, which penetrates the outer skin of fibreglass, will seep into the plywood core and could cause rot in the future.
Unless double skinned there can also be a problem with internal condensation.

Q12. Which box van construction, is the best to convert?

A. The two most popular forms of van construction are: -
a). Aluminium. The original operator for maximum payload would specify an aluminium container. The construction of such containers are therefore the lightest available, without any consideration to the overall strength of the unit. They can be strengthened, but this takes time and money. Also by the time they become available to us they are usually scratched and dented on the external face.
Not the finish we require for our new horsebox! REMEMBER it requires the same investment in time and money to convert a bad container
as it does a good one.
b). GRP/GRP Board/Glasonite/Fibreglass Faced.
GRP board has a tougher external face, therefore standing up better to the occasional knock.
The disadvantages are that as a raw material it is heavier than aluminium, and is vulnerable to dampness ingress, which can cause the internal core (plywood) to rot without it being apparent from a visible external examination. In addition we must bolt through to the external face to achieve any meaningful fix.
(With a frame construction we have vertical uprights at regular intervals enabling us to achieve a strong fix for partition mountings etc. etc.)

Q13. Should we retain the tilt cab facility?

A. We consider the decision to tilt or not is dependent on the value of the living to the customer. If it is intended to use the living for regular overnight stops, with maybe a number of multi-nights away, the water and draught-proofing problems associated with the hinged front flap, lifting floor and detachable cab access, does not seem a practical option.
If the living were just for day use, with the Luton front more for looks than of real value, we would suggest retaining the tilt cab.
Remember, the asset value of the horsebox is usually increased with a coachbuilt front and full cab access.
On a non-tilt cab unit making the raised section of floor between the driver and passenger seats completely removable can access the engine.
From this access most of the routine engine servicing can be carried out with only a minimum of inconvenience. Should the worst happen and the engine require taking out, the front axle will have to be dropped. As would also be the case if a fixed Luton front was in place, as there is a limited amount of space between the engine and the underside of the Luton. Not enough space for lifting tackle to remove the engine.

Q14. What size container do we need?

A. There are a number of points to consider here.
a). The number of horses to be carried.
b). Size of horses.
c). Living area requirement.
d). Any parking or access limitation.
d). Weight.
In the trade we work on 1mtr (33") for each horse, and 600 cm (24") for ponies. These sizes are for guidance only.
Based on the above a 3 horse could need 9/10' (2.8mtr/3.2mtr).
The same area could accommodate 4 ponies.
A comfortable day living would need 6'-0" (1.8mtr). A toilet/shower or tack area could be fitted into 3'-0" (90cm).
Based on the above an 18'-0" (5.4mtr) container would be adequate.
If you plan to travel herringbone, an 8'-0" (2.45mtr) Wide container would be the best option. We would build a new box to height of 7'-6" (2.25mtr).
In box van terms, this would usually mean an 8'-0" high unit.
REMEMBER height is not just clearance for the horses ears,
but VOLUME. ie. air space.
The greater the volume the more air there is around the horse. This will lead to a more comfortable horse area. An 8'-0" high container on a 7.5 ton chassis
(17.5" wheels) will be approx. 11'-6" high overall.
Any higher than this may give problems with the occasional low bridge, but will certainly give problems with tree branches.

Q15. Which ramp spring system is best?

A. The two most popular systems are:
a) Under slung or b) Exposed side springs.
Of the two, side springs are the most efficient, and the easiest to fit, whilst offering the maximum adjustment.
The system can be fine-tuned so one person can easily lift the ramp.
Unfortunately they don't look as good as unders!
Under springs are by far the most popular.
They require the ramp to be hung in such a way that the drop mounting plates do not infringe the underside of the hanging rail when the ramp
is lowered to the floor.
We supply the spring set with a number of adjustments, enabling the DIY installer achieve a professionally balanced ramp.
In short neither can be said to be best.
Both have their advantages and disadvantages.
For the inexperienced the sides are less problematical.
The unders look better, but don't work quite as well.

Q16. Why do you recommend heavy and expensive rubber flooring in the
horse area?

A. A good quality rubber flooring with a minimum thickness of 10mm. helps the horse achieve a positive grip.
Thin cheap rubber doesn't offer much grip and is less hard wearing.
We supply both 10mm ribbed sheet and liquid granulistic.
Both are good value for money.

Q17. How much ventilation should we allow?

A. It is usual to allow for two opening windows (one nearside, one offside) for each horse carried. The windows must be made from toughened glass, with the head window opening protected by vertical bars.
(Horizontal bars are more vulnerable to a bored horse).
back to top



Q18. Why on "FOXLEA" boxes do you block out the light from the
fibreglass roof?

A. Our usual treatment of the roof is to insulate between the roof sticks, and then Under-draw with white polyester coated ply. The opaque fibreglass acts in a similar manner to a greenhouse.
It only needs to be a bright spring day and the temperature can rise alarmingly.
One of the most common causes of horses sweating up in transit can be traced to an increase in temperature and the lack of ventilation.
A bonus with the above treatment is the reduction in condensation in cold weather.

Q19. What are the advantages of the half-skirted partition?

A. Whilst in transit the horse will be continually trying to balance against the movement of the vehicle. With a half skirt partition we can allow the horse to be snug at his flanks whilst improving his balance by spreading his feet beyond the partition line. By comparison, with a full-length partition if we allow space at floor level for the horse to spread his feet, his upper body will be bouncing in a space too wide for his width.
REMEMBER. We can discuss the theories all day, but it is down to you to establish the method which suits your horses best.
