Designed, manufactured in accordance with the Regulations World Athletics (WA Certificate: E-04-0387).
Automatically operated hurdle. By setting the height of the board through the activation of the triggers located below it, the counterweights of the bases are automatically housed in the corresponding place according to regulations.
Composed of a base made of extruded aluminium profiles with a specific design that allows easy movement of the counterweights. The profile is closed by means of injected plastic covers both at the front and back.
At the base perpendicularly and in its two front corners, two aluminium tubes of circular section and own design are inserted that position the crossbar at different heights (1.067 m, 1.00 m, 0.914 m, 0.838 m, 0.762 m) by means of handles that in turn move the counterweights housed in the base to the proper position. In said aluminium tubes the mechanism is inserted so that they have no possibility of displacement.
The wooden crossbar, painted according to regulations, is held by two special pieces of injected plastic with a rounded wedge shape in order to avoid physical damage to the athletes. The plastic parts are housed in the upper part of each one of the two aluminium profiles with a circular section that moves vertically, being fixed by means of holes to a stainless-steel bolt. It has a measuring scale to set the different established heights.
The base is prepared to facilitate stacking thanks to the design of the aluminium profile.
The structure is painted with polyester powder paint, which is applied after degreasing treatment, which takes place in pressurised phosphatising bath, and polymerised in an oven at 200º C.
