POLE VAULT

The Pole Vault facility includes a runway, a box for inserting the pole, two uprights with crossbar and a landing area.

METHOD OF MARKING

Method of marking a runway are same as given in javelin.

The Runway
The minimum length of the runway shall be 40m and the runway is measured from beginning of the runway to the 0-line. It shall have a width of 1.22m ± 0.01m and shall be marked by white lines 5cm in width. The maximum lateral inclination of the runway shall be 1:100 and in the last 40m of the runway the overall downward inclination in the direction of running shall not exceed 1:1000.

Apparatus

BOX
The take-off for the Pole Vault shall be from a box. It shall be constructed of suitable material, preferably with rounded upper edges and shall be sunk level with the runway. It shall be 1m in length, measured along the inside of the bottom of the box, 60cm in width at the front end and tapering to 15cm in width at the bottom of the stop board. The length of the box at runway level and the depth of the stop board are determined by the angle of 105° formed between the base and the stop board. The base of the box shall slope from runway level at the front end to a vertical distance below ground level of 20cm at the point where it meets the stop board. The box should be constructed in such a manner that the sides slope outwards and end next to the stop board at an angle of approximately 120° to the base. If the box is constructed of wood, the bottom shall be lined with 2.5mm sheet metal for a distance of 80cm from the front of the box.

Uprights
The two uprights must be able to be installed on horizontal bases, level with the O-line, such that each can be moved from the 0-line not less than 0.80m towards the landing area (e.g. on a built-in double rail) or in fixed sockets with movable cross bar supports. They must be not less than 5.20m apart with approximately 0.10m between each upright and the landing mat. The lower part of the uprights shall be covered with appropriate padding to protect the athletes and their poles. The landing mats shall be recessed to take the uprights and any horizontal bases. Separate protective pads shall be installed as necessary.

Crossbar support
The crossbar shall rest on pegs so that if it is touched by an athlete or his pole, it will fall easily to the ground in the direction of the landing area. The pegs shall be without notches or indentations of any kind, of uniform thickness throughout and not more than 13mm in diameter. They shall not extend more than 55mm from the supporting members, which shall be smooth and extend 35-40mm above the pegs. The distance between the pegs shall be 4.30-4.37m. The pegs shall not be covered with rubber or with any other material which has the effect of increasing the friction between them and the surface of the bar, nor may they have any kind of springs.

The Landing Area
The landing area shall be not smaller than 6m long (behind the zero line and excluding the front pieces) x 6m wide x 0.8m high. The front pieces must be at least 2m long. The sides of the landing area nearest to the box shall be placed 10cm to 15cm from the box and shall slope away from the box at an angle of approximately 45°.
