Mobile Cross Country Jumps
The SpirafixTM 50mm C type ground anchors have now been accepted as the de facto standard
for securing mobile cross country jumps and are to be used at the London Olympics in 2012. Sue
Benson, the course designer said “The fences will be fixed to the ground using Spirafix ground
anchors”, an ecologically friendly alternative to posts and added that she would be able to be
"flexible" with her design "up to the last minute".
Here’s an extract from “The Builders' Forum” by Dan Stark, Eventing USA | Issue Three | 2009
Another anchoring system worth mentioning has recently become available. Eric Bull
(ETBjump.com) is making a stake modeled after one used by the British Military. Last fall, at the
annual course builders’ seminar at Burghley Horse Trials, he observed a graphic demonstration of
portable jump staking. A cable was hooked between the top of a jump and a winch with a scale
measuring the force of pull. Builders were invited to stake the jump using their preferred
techniques. The force needed to move the jump was measured for each. The jump consistently
moved at forces less than those measured in horse/jump collisions. Then the “new” anchors
(actually “Spirafix Anchors”) were set. When the winch was engaged, the rail threatened to break
while the anchors held fast.
