VEHICLE MOBILITY SOLUTIONS – BY RVM

RVM B.V. is a Netherlands based company that specializes in woven fabrics. The Vehicle Mobility product range enables drivers around the globe to keep their vehicle moving whenever transport roads are in poor condition or not available at all. They are successfully used by the military, mining companies, 4wd owners and emergency search and rescue services. RVM provides them with easy-to-use surfaces that last.

Heavy Trackway

The RVM Heavy Trackway, Mammoth mat is an portable road. Together with the Fast deployment Tool within a few minutes a road can be laid out, which is 4 meter wide and 25 meter long. In length direction the mat is reinforced by galvanised steel wires and in transverse direction by steel rods. The spring steel rods provide the mat with so called membrane action, enabling it to transfer high wheel loads to the sub-soil without significant rutting or permanent deformation. The mat was especially developed by RVM to allow heavy vehicles to operate in soft terrain without the risk of bogging. The Heavy Trackway, Mammoth mat requires no maintenance, can be used many times without noticeable wear and tear Its flexibility and light weight( 15 kg. / m2 ) makes it easy to roll, drag retrieve and store. The Mammoth mat consists of woven polypropylene fabric with high strength, durability and resistance against chemicals and UV light. Bogging occurs if the Mammoth mat is not used. The Mammoth mat can be used on all types of soft soil, i.e. fine non cohesive sand, clay loam or peat in marshland or in swampy areas.Typical Mammoth mat applications are:

– To make marshy terrains passable for heavy traffic.

– As a building road to an construction site.

– As an emergency road where main road is under repair.

– As a swerving of area or hard standing for heavy equipment.

– To connect a temporary bridge or a ferry with existing roads.

– As a boat landing for landing barges and amphibian vehicles.

– For runways for small airplanes.

– For emergency airfields.

– Platforms for crane operation.

HeliPad

The RVM HeliPad is a safe and stable landing area for helicopters without encountering any obstacles. The need for a clearly marked, safe landing area is evident knowing the effects of a brownout or a whiteout, also called DVE (Degraded Visual Environment). The helicopter rotor downwash creates a dust cloud that minimizes the visual orientation of the pilot. The ground crew gets sandblasted when working in the rotor downwash area if not working with a HeliPad. The brownout also increases wear and tear of engine and rotor due to FOD (foreignobject debris). In order to prevent dust, sand or objects to get airborne due to the rotor downwash, RVM engineers have designed a super lightweight, reinforced HeliPad. Woven fabric panels, put together in length direction or sideways will form the RVM HeliPad. The fabric is woven from specially treated PP yarns together with carbon rod reinforcement in cross direction. With the HeliPad, a smooth surface can be created, covering the dust particles and improving the ground characteristics. The Portable helicopter platform is light weight, easy toinstall, easy to carry and easy to store due to the roll able panels. The size of the platform is flexible by connecting as many panels as needed. Due to the Modular character of the HeliPad it is available in sizes that match the rotor diameter and harsh environment of the situation.

Light Trackway

RVM Vehicle Mobility has developed a Light Trackway for the Amphibious Support Battalion of the Royal Dutch Marine Corps. This division of the Dutch Marine Corps was searching for a light version of the already successful Mammoth mat. The main question was that the Marines would be able to deploy the mat manually so it was not allowed to exceed the total weight of 150 kg. Furthermore it had to be able to carry a wide diversity of equipment like trucks, land rovers, wheel loaders and some tracked vehicles. As shown on the pictures the Light Trackway had to be able to withstand very severe conditions like in the artic area. The product has now further developed into the landscaping area as show by tests done in Canada and the USA.

Bogstrips

The RVM Bog Strips may be used to facilitate the passage of wheeled vehicles across ground that would otherwise be impassable to them; they may also be used to assist in he recovery of a bogged vehicle, including in conjunction with a self-recovery winch or towing vehicle in the case of badly bogged vehicles. Bog Strips may be used in a variety of terrain including loose sand and soft mud, and after use are easily cleaned and stored, rolled up for future use.

Bog Strips are manufactured from a woven synthetic fabric composed of deltaflex yarns, which are specially made to reduce the risk of overheating the fabric under spinning wheel conditions. For reinforcement Bog Strips include transversely located flexible glassfibre rods.Two types are presently vailable, the “Classic” version 5,50 x 0,50m and the “Commercial” version 2,75 x 0,50m.

Individual strips are light enough to be handled by one person and using four strips allows ‘leap-frogging’, enabling a vehicle, for example, to make a climb up through sand dunes or across a wide expanse of soft mud. A simple steel anchor or peg can be used to fix Bog Strips to the ground in particularly slippery surface conditions.
