Javelin cart consists of a main body made of polyethylene and metal supports in steel.
The main body is made of rotational moulding PE C6 polyethylene with a density of 0.935 g/cm³, finished in a textured outer surface. This material has protection against ultraviolet UV rays and is unalterable to atmospheric agents.
It is equipped with four wheels, the rear ones are swivel and the front ones, somewhat larger, are fixed. All of them have a smooth rubber tread and are mounted on axles, allowing the movement of the cart in all directions.
It has a set of cylindrical holes where to place the javelins in a vertical position, with a capacity for 20 units of any regulatory size, and some strips of sports flooring in the lower part where the tip of the javelin rests, so that it does not move and they protect the javelin and the cart.
The cart also has a chalk holder, a spherical container made of translucent coloured polyethylene with a diameter of 400 mm which, thanks to its design, keeps the chalk protected against drafts.
