Olympic Series | SERAPOOL Porselen

194 Anchors should be installed to withstand 20kN. Each lane rope will consist of wave reducing components placed end-to-end having a minimum diameter of 0,10 metre. The design of discs and floats should be so that the floats, by themselves, do not influence the length of the lane rope. A float should be an integral part in between two discs. The lane rope length of the course shall have a negative buoyancy in such a way that at least one half to maximum two thirds of the height of the wave reducing components should be beneath the water surface. The take-up reel of the lane rope should require a tool to lock tensioning into position and to prevent non-authorized tampering. The lane rope shall be equipped with a tension spring, absorbing sudden high point loads and a wire withstanding a tensile force of 12kN. In an 8 lane swimming pool the colour of the lane ropes should be as follows: • Two (2) GREEN ropes for lanes 1 and 8 • Four (4) BLUE ropes for lanes 2, 3, 6 and 7 • Three (3) YELLOW ropes for lanes 4 and 5 The components extending for a distance of 5.0 metres from each end of the pool shall be of RED colour. There shall not be more than one lane rope between each lane. The lane ropes shall be firmly stretched and the tensions should be 1-1,2kN. See Swimming Diagrams, Annex SW 1 FR 2.1.7.2 At the 15-metre mark from each end wall of the pool the components shall be distinct in colour from the surrounding components. FR 2.1.7.3 In 50 metre pools the components shall be distinct to mark 25 metres. FR 2.1.7.4 Lane numbers of soft material may be placed on the lane ropes at the start and turning end of the pool. FR 2.1.8 Starting Platforms Starting Platforms shall be firm and give no springing effect. The height of the platform above the water surface shall be from 0.5 metre to 0.75 metre. The surface area shall be at least 0.5 metre x 0.5 metre and covered with a slip-resistant material. Maximum slope shall not be more than 10 degrees. The starting platform may have an adjustable setting back plate. The platform shall be constructed so as to permit the gripping of the platform by the swimmer in the forward start at the front and the sides; it is recommended that, if the thickness of the starting platform exceeds 0.04 metre, grips of at least 0.1 metre width on each side and 0.4 metre width in the front be cut out to 0.03 metre from the surface of the platform. Handgrips for the forward start may be installed on the sides of the starting platforms. Handgrips for backstroke starts shall be placed within 0.3 mete to 0.6 metre above the water surface both horizontally and vertically. They shall be parallel to the surface of the end wall and must not protrude beyond the end wall. A minimum depth of 1.35 metres, extending from 1.0 metre to at least 6.0 metres from the end wall is required for pools with starting blocks. Electronic read-out boards may be installed under the blocks. Flashing is not allowed. Figures must not move during a backstroke start. FR 2.1.9 Numbering Each starting block must be distinctly numbered on all four sides, clearly visible. It is recommended that lane number 0 shall be on the right-hand side when facing the course from the starting end with exception of 50m events, which may start from the opposite end. Touch panels may be numbered on the top part. FR 2.1.10 Backstroke Turn Indicators Flagged ropes shall be suspended across the pool, 1.8 metres above the water surface, from fixed standards placed 5.0 metres from each end wall. Distinctive marks must be placed on both sides of the pool, and where possible on each lane rope, 15.0 metres from each end wall. FR 2.1.11 Backstroke Ledge A backstroke ledge may be used: • The ledge may be adjustable to 4 cm above or 4 cm below the water level. • The ledge is a minimum of 65 cm in length. • The ledge must be 8 cm in height, 2 cm at the width with 10 degrees of slope
