Track and Field Equipment

Track and Field Equipment

The throwing chair is tied down to the ground to provide stability for the thrower. Without tie-downs, the chair can move out from under the thrower as they apply a large amount of force on the chair. Tie-downs are ratchet straps and metal stakes should be used at a minimum of all four corners. Concrete stakes put into the ground at an angle work well, if the ratchet strap has a circle just ahead of the hook. It is not advisable to use aluminum stakes as a very sharp edge will form on the top. Use a sledge hammer to hammer stakes into the ground at a 60 degree angle and angled away from the athlete. The ground should be level. An alternative is a portable ring made of angle irons with holes that the ratchet strap hooks will fit into to secure the chair.
