Launch ATLm hammer
1 TAMAÑO OF THE LAUNCH AREA
The launch area of hammer consists of launching circle registered in a platform, a protective cage and fall of the device. The circle will have an inner diameter of 2,135 m (± 5 mm). The crash sector will have a hammer Angle and a length 34,92º unlimited though related to the level and athletic category of competing launchers. See the drawings
and the following table:
|LAUNCHING AREA OF HAMMER|
|LONGITUDE SECTOR MÍNIMA (m)||90||70|
Installation for the launch of hammer can be combined with the launch of disk, for which the diameter of the circle will launch of 2.50 m at 2,135 m (± 5 mm) for the launch of hammer, placing an internal circular ring 0,1825 m outer ring and 0.02 m in height. The ring will be inserted set to launch circle so that is level with the external ring and does not cause risk to athletes. Will Be painted white.
The fall can accurately be drawn by establishing a 12 m distance between two points located on each line of the sector to 20 m from the center of the circle. For each metro progress from the center of the circle, the distance between the line of the sector is increased by 0.60 m.
2 OUTER BANDS AND SECURITY
To facilitate the development and vision of the competition by athletes and spectators, bands will be reserved minimum free spaces around the circle and around the perimeter of the sector of falls. Space around the circle of launch and foreign shelf should be limited by a circle concentric with him and 10 m. of diameter. The angle of the sector of crashes (34,92º) must be complemented in the sides by two sectors circular 10th in whose space should not be permitted to access unauthorized persons during the launch by security measure, it is advisable to place an additional fence at least 1m tall outside the sector. This fence also serves to stop sliding devices.
3 HEIGHT OBSTÁCULOS FREE
The height between the pavement and pavement and the nearest obstacle (power lines in outdoor facilities; underside of roof, hang beam, luminaire, through air conditioning in covered facilities) both on the area as on the outer bands, should be entirely free and have a minimum of 12 m. In modules covered with training, will suffice the existence of such free height in the first ten metres from the drop sector.
SOLAR ORIENTACIÓN 4
The central axis of the circle of launches and falls can be oriented in the geographic address for as long as is not covered by the environment O-SO (area) / N-NE (circle).
TYPE OF FLOORING 5
The circle of launches will be a pavement different characteristics in crashes and external gangs. The pavement of the circle must have solved the drainage superficial and deep waters, as well as being rough and not slippery, not abrasive, consistent and equipped with safety underfoot, all this in order to be an area suitable for the evolution of the launchers. The circle is typically formed by a concrete floor 25 N / mm2 of resistance to compression, armed with
metal mesh and finishing ruleteado to have sufficient adhesion and getting a flat horizontal surface. If used asphalt or other material, have a similar characteristics. At the edge of the circle will be three sewer (for example: tubes of brass or PVC 20 mm diameter) distributed uniformly and level of the surface of a circle, which will reach permeable infrastructure or are connected to the network of drainage.
The center of the circle of launches from which you measure distances will be signposted and preferably through a brass pipe 4 mm in diameter interior placed at surface level of the circle.
The pavement of crashes sector and its outer bands admitted a maximum outstanding in the direction of the launch of 1 per 1000, to enable the evacuation of superficial waters. The pavement must have solved the drainage deep waters, as well as being a deformable enough material to the impact left clear mark, without causing irreparable damage and without having to sign the footsteps of judges and competitors. The pavement will pitch, preferably, for national and international competitions, and for other competitions in its default, clay or ashes.
Artificial lighting is uniform and so that does not cause glare of athletes, judges nor spectators. Mark the standard UNE-EN 12193 “ Illumination of sports facilities ” and will have the following minimum levels of illumination:
|LEVELS OF ILUMINACIÓN MÍNIMOS
ATHLETICS abroad (all activities)
|COMPETICIÓN LEVEL||Horizontal illuminance|
|And med (lux)||Uniformity
And min / Emed
|International and national competitions||500||0.7|
|Local and regional competitions, training high level||200||0.5|
|Training, school sport and recreation||100||0.5|
In launches of disk, hammer and javelin precautions should be taken to ensure the safety of people, because the object launched can leave the illuminated area and be invisible in part of your flight.
For TV broadcasts of color and recording movies requires a vertical illuminance levels of at least 1,000 lux and 1,400 lux in international competitions, however this value can increase with distance from the camera to the object. For more information regarding vertical illuminance, uniformity, color temperature and Performance index of color must consult the mentioned law.
7 ROUTE OF THE AREA
The layout of the area of launches will agree with drawings
Launch areas hammer should be located in full independence and different location of the remaining athletic fields, with the exception of the possible and partial overlap in their sectors of fall with launches weight, disk and javelin.
Launch areas hammer will consist of a single circle and sector or by several circles and sectors to allow a sports practiced simultaneously.
The location in the track is generally within the semicircles near the edges of the opposite straight to the target, fall is located in the grass area of the interior of the track.
The width of the lines (whitewashed graffiti or) or existing tapes is 5 cm, remain outside areas that delimit. The marking of lines on the platform of the circle must be perfectly acceded, be permanent as well as enrasar with
The marking of lines or tapes on the sector falls must be perfectly acceded and be mobile, unless it is independent character to others.
The full route, you can specify the following details:
7a) median line of the circle: Is the line that restricts the later half of the circle. Is perpendicular to the central axis of the sector declines, coinciding its posterior edge with the center of the circle. line runs and pintará at least 75 cm outside the circle and from both ends with a width of 5 cm and white.
Outside the platform, the line may be painted, made of wood or some other appropriate material.
7b) lateral Lines: the drops sector will be limited by dissymmetric lines are determined as follows: The sidelines of drop sector can be accurately establishing a 12m distance between two points located on each line of the sector to 20 m from the center of the circle. For each metro progress from the center of the circle the distance between sector lines will increase in 0.60 m
The sector aperture (straight separation between the edges of the “ interior lateral lines ”) for a certain distance, must be obtained by multiplying the distance by the factor 0.60.
7c) indicator Lines of distance: Is optional marking over the area of crashes of certain lines that indicate entire distances launch 5 in 5 meters. These lines will be plotted circumference arches with centre in the circle and with 35-40-45-50-55 radios m.... to mark these distances. These arches facilitate visually appraising distances by launchers and spectators.
8 THE CIRCLE
The hammer should jumping off a circle of the dimensions indicated in point 1. See drawings
Circumference circle limit consist of a flat sheet iron, steel or another suitable material, thick minimum 6 mm. The device is typically formed by a series of pieces curves to look jointly to the base platform the circle, so that their faces interiors constitute a perfect circumference of 6,707 mm (± 15mm) The device will be set so that its top face is at the same level as the ground outside and 20 mm (± 6 mm) higher than the inner surface of the circle. This device will be ready to resist all weather conditions, and should be painted white on their faces views. It will allow the existence and use of portable character circles if and when all of the above.
9 BANNERS OR INDICATORS
9th) Banners in the sector: The sector banners are those that complete the extremes of the “ lines of the industry side. ” Will be fully protected metal corrosion, no metal oxidable or other appropriate material. The banderola will be rectangular and of about 400 x 200 mm. The mast will take 8 mm diameter, rising on the level of the pavement a minimum of 600 mm.
9b) indicators of distance: Can be indicators of distance at the intersection of “ sector lateral lines ” and “ indicator lines of distances ” Unregulated characteristics.
9c) Banners indicators: Depending on the category of the competition, it should be noted with a banner or special disk distance from the current record, either global, continental, national. Furthermore there will be banner or a distinctive indicator to bring the best launch of each contestant must be placed over a line or ribbon outside of the “ sector lateral lines ”.
The hammer consists of three parts: a metal head, a cable and a handgrip or handle. See drawings
10th) Head: The head will take spherical shape. It Will Be thick, iron, brass or other material harder than the latter, or a wrapper of any of these metals, fill out of lead or other material solid. If you must be placed Fill in such a way that is set in stone. The center of gravity, in any case, you must be located up to 6 mm from the center of the area. The head of the hammer, devoid of cable and the handgrip, which should be in balance to place it on a hole horizontal, circular of 12 mm diameter with foreign and finished in external circumference Edge alive.See ATLm-8 drawing.
10b) Cable: The cable be straight steel wire and unbreakable, 3mm diameter as a minimum, that cannot delay significantly during the execution of the launch. This cable can be folded in ring in one or both ends as a means of union.
10c) or Grip handle: The grip handle or consist of one or two handles of cable. Will be solid and rigid, in one piece, without hinges of any kind, and made in such a way that cannot be extended so sensitive during the launch. Will Take the form of isosceles triangle or sector in a circle. The handle can have a curved or straight grip and its interior will have a maximum width of 130 mm and a maximum length of 110 mm minimum Resistance to handle broken shall be 20 kN (2000Kgf).
10d) cable Joints: The cable will be linked to head the hammer through a form of articulation in swivel, which can be simple or mounted on a ball bearings. The handgrip will be united to the cable through a fold in keyring It, never by a swivel, so that to flip the hammer, cannot increase the total length of the device. The characteristics of the hammer are fixed in the following table:
|Mass (1) (g)||lab
|Minimum mass (2) (g)||7000||6000||5000||4000|
|Length of the hammer measured from the inner edge of the handle (mm)||Min.||1175||1175||1165||1160|

For the categories Infantil (3kg), Swim (2kg) and Baby (2kg), men and women the Real Spanish Federation athletics has developed some evidence and a system of alternative competition.
11 THE CAGE
All launches should be performed from inside a “ cage ” to ensure the safety of spectators, judges and launchers. The design of the “ cage ” depends on constructive characteristics defined by the manufacturer provided you meet regulatory factors listed below.
These factors are provided when the “ cage ” is located in a stadium with spectators located around the perimeter of the track and field when interior combined with the launch of hammer other athletics.
When the “ cage ” or “ cages ”, is present in another situation, (usually areas for training of launches), you can afford a simpler design.
The “ cage ” will be designed, built and maintained in such a way that is able to stop the head of a hammer of 7,260 Kg. moving at a speed of up to 32 meters per second. Likewise shall not be danger rebound in the fixed elements of the “ cage ”, hitting the launcher or escaping from the top of the “ cage ”. On the other hand, no hammer may make their way through any board of the “ cage ” or below the panels.
11th) dimensions of the “ cage ”: “ cage ” should take into plant form of Or as indicated in the drawings ATLm-9 a and b, the width of the mouth will be 6 m and will be located at a distance of 7 m in front of the center of the circle of launch. The front of the cage will be equipped with two panels of mobile network of 2 m wide, of whom only one will be operational each time, the minimum height of the panels of mobile network must be 10 m. The height of the network or panels pendant network on the back of the cage must be at least 7 m and for the past panels adjacent to the revolving doors of 2.80 m, will be 10 m at least. The network will be a minimum of 3.50m from the center of the circle. The left mobile panel is used for athletes that turn in the opposite direction-clockwise and the right to athletes that revolve in the sense clockwise. Given the need to change a panel to another during the competition where present launchers, both left-handers as dexterous, it is essential that these changes require little work and can be performed in a minimum time. The final position of both panels indicated in the drawing, although in the competition only a panel will be closed and only at the time of the attempt. when you are in operation, the mobile panel will have to be exactly at the given index. Will therefore be taken steps in the design of mobile panels for acerrojarlos if they are in a position operational. The construction of these mobile panels and its operation depends on the complete design of the cage and can be with a sliding system, engoznados in a horizontal or vertical axis or demountable. The Only firm requirements are that the panel in operation has to be fully able to stop any hammer that he beats and may not have no danger that can be opened a hammer path between the panels and mobiles.
11b) the network: The network for the cage can be made of appropriate string of natural or synthetic fiber or, alternatively, or highly ductile steel wire tensible. The maximum size of the mesh should be 50 mm for the wire and 44 mm for the network of string.
The minimum extent of the bulk of the wire mesh or depends on the construction of the cage, but the force of resistance to breakage must be, at least, 300kg. In order to ensure the continued safety of the cage, the network of steel shall be inspected at least every 12 months. The visual inspection is not enough for the string of fiber. Instead, should be inserted in the network by the
manufacturers several pieces of displays (tell-tale) of the string standard. One of these can check and be checked every 12 months to ensure the continued resistance of the network.
The network can be made into sections or continuously suspended from a frame or structure well supported and strengthened. It is desirable that the network can be raised and lowered quickly, the network will be suspended without touching on the poles of support for that cannot beat them by a device launched. The poles of support front panels or doors will blink manually with ease and will be built so that they can ensure firmly on the positions required.
11c) Structure: The structure of the cage will generally be formed by poles or vertical metal brackets to sustain a metallic piece to 7m / 10m high set by the bodies or panels which constitute the cage. The structure of the cage will be sufficiently rigid so that does not deviate from its position due to the weight of the network or to the force of the wind.
11d) Subject and editing: The metallic piece will sustentante united solidarity in brackets. The setting to the floor of the media must be preferably through a tube of anchor with cover the depth of Docking (at least 30 cm) to provide adequate rigidity. The whole cage, will resist the thrust of the wind.
11 and) Painted: all the metal elements should be prepared to resist all weather conditions and painted a color that contrast perfectly with the background.
Generally builds the protective cage combined for launches the disk and martillo.Cuando would wish to use the same cage for the launch of disk, the installation can be adapted two alternative forms. The simplest is a circle in which fit two concentric rings, 2,135 m and 2,500 m, but this involves using the same surface of the circle to launches the hammer and disk. The hammer cage will be used for the launch of setting disk panels mobile network outside the opening of the cage.
When you want to have separate circles to hammer and disk in the same cage, the two will have to be placed circles behind each other with their separate facilities 2.37 m in the central line of fall, and with the circle of the disk on the front. In this case panels mobile network will be used for the launch of disk
The sector of maximum danger to hammer launches from this cage, when it is used by the skilful launchers and left-handers in the same competition is approximately fifty-one. the position and alignment of the cage in the field is therefore critical to its safe use.
Is placed outside the “ cage ” furniture for judges to develop their work.
