One important factor in assessing artificial turf surfaces is the interaction between the ball and the field. The various sports federations such as FIFA have set up a number of requirements for artificial turf. The ball roll and ball rebound characteristics are one of them. Especially for clubs, municipalities, installers and maintenance companies, Deltec developed the Club Ramp with Ball Rebound to test the ball roll and ball rebound.
Requirements:
The ball has to be positioned at 1 meter height
45 degree slope with 2 rails
Smooth transition from ramp to surface by means of a 500mm radius
The distance of the continued rolling of the ball is measured. This measurement is taken in several directions and different locations on the field. For the ball rebound the ball has to start from 2 meters height, then the rebound height is measured.
Your benefits:
2 tests in one device

Clear measuring scale
In leighweight aluminium
