One of the few UK horseboxes offering a 5-passenger cab, the Proteo model comes with a 5 seat cab and this maximises the space in the cab to give all of your passengers a very comfortable ride.

Cab Area
The 5-passenger cab is arranged around 2 front seats and a 3-seat back bench. Depending on the chosen options, it’s possible to rotate the front seats and add a table as to create a nice and relaxing space. The back bench can also be transformed into double bunk beds with curtains. The vehicle can be designed with access to the luton from the horsepart – which enables to add some significant storage space, or the luton can be designed as to be accessible from the cabin offering an extra bunk. There are 3 point seat belts on the rear seat enabling you to carry your passengers including small children very safely. Theault are one of a few companies building UK horseboxes that can legally build the 5 seater models, safety is paramount.

Built on the latest Euro 6 Renault Master chassis with a 170 HP engine either manual or auto transmission, the Proteo guarantees full driving enjoyment thanks to its modern and efficient engines. The powerful engines enable to easily couple a trailer to your horsebox and also ensures better fuel efficiency, more endurance and a silent functioning. The interior is designed to be like stepping into your car, with all the latest technology that you would expect in your car, to enable a smooth transition between your vehicles. For relaxing moments, the new and insulated luton offers a great rest area for the passengers.

EC Type Approval (RCE European Homologation)
The Proteo models offer all the safety features that Theault are renowned for including a crashtested bulkhead wall, which is all part of the European RCE Homologation, as a pioneer . In 2010, THEAULT was the first horsebox manufacturer in the UK & Europe to obtain the EC Type Approval (RCE European homologation) thanks to its strong focus on safety the RCE homologation relies on a rigorous series of technical tests, validation processes and trials. This enables customers on a budget to still be able to afford the safest transport for their horses and passengers.

Horse Area
Manufactured in France in the factory in Normandy, Proteo is the result of THEAULT’s team sharp know-how that guarantees uncompromising quality. The insulated sandwich panels with polyurethane foam used to manufacture the body provides significant advantages. In addition to heat and sound insulation, such material is very light, rot-proof and resistant to ageing. The core parts of the horsebox (body, lateral panels, rear frame, partition…) as well as the insulated luton are designed collectively to be light and resistant to provide safety and comfort to horses and passengers.

Thanks to its innovative 7 positions easy sliding partition, quickly adapting the horse area depending on your transportation constraints. Load and unload your horses from the spacious stalls, with the wide and secure side-ramp you will appreciate the ease with which the ramp lifts and the doors click silently shut. The improved sound absorption and cabin isolation maximizes transportation comfort for horses and passengers. The rear door is available in 3 different configurations as to easily access the tack-room when your horsebox is coupled to a trailer.

Safety Testing
The panels have been successfully tested on a crash performance by the UTAC (French organization called “Union Technique de l’Automobile et du Cycle” which means Technical Union for Motor vehicles and Cycles), single French entity accredited to conduct such tests. The panels resist to a 1350 kg effort on every anchor point of the security belts. Thanks to this tests, the 3 and 5 passenger cabins have been homologated, certifying the very high resistance of the panels in case of emergency braking or impact. Great attention has been set on the key parts of the horsebox, especially the ones that are subject to high pressures (panels, breast separation tube, partition…) Designed as a single piece of aluminium, without any welding nor joints, these parts are thought to have the best weight / resistance ratio. Besides a specific non-slip treatment on the horse part, the wide and secure side-ramp enables to load and unload horses in complete safety. The partition can be easily handled and moved in just a few turns. The wide rear door has been designed to allow rapid horse evacuation if necessary.

Tack room options
With many possible configurations, you may design your tack-room in multiple layouts. By adding different types of lockers, shelving, hanging rails, drawers… the grooms area adapts according to your discipline.
Among the possible equipment and accessories: saddle and bridle-racks, mirror, lockers with roller door, mobile saddle box or even a water supply. The tack locker unit closes with a roller door securing equipment during transportation, while ensuring lockable storage when away from the stables.This model can come very simple or can be made as luxurious as you desire.
