A drop tester (1) including a gripper mechanism (2) for holding a product (37) to be tested, a guide track, a slider block (3) which is mounted to slide along the guide track and advance the mechanism toward a target location (41) and a release device (40) for triggering release of the product from the mechanism to impact at the target location, characterised in that the gripper mechanism includes gripper arms (15, 16) coupled to the slider block, the gripper arms being rotatable relative to the slider block to enable the orientation of the product to be varied, relative to the target location. The slider block is preferably releasably coupled to a hoisting block (4) which is positionable at a predetermined location along the guide track. More preferably, the gripper arms are pivotally mounted to a housing (23) and coupled to a piston (22) provided within the housing, the arms pivoting between a gripping position and a release position upon advancement of the piston through the housing.

L'invention porte sur un testeur (1) comprenant un mécanisme de préhension (2) servant à retenir un produit (37) à tester, une voie de guidage, un bloc coulissant (3) monté de façon à coulisser le long de la voie de guidage et à faire avancer le mécanisme vers un point cible (41), et un dispositif de dégagement (40) servant à déclencher le dégagement du produit du mécanisme de sorte que le produit retombe sur le point cible. Ce testeur se caractérise en ce que le mécanisme de préhension comporte des bras (156, 16) de préhension couplés au bloc coulissant et pouvant effectuer une rotation par rapport au bloc coulissant afin de pouvoir orienter le produit dans diverses directions par rapport au point cible. Le bloc coulissant est de préférence couplé amovible à une moufle fixe (4) pouvant se positionner à un endroit prédéterminé le long de la voie de guidage. Les bras de préhension sont idéalement montés pivotants sur un corps (23) et couplés à un piston (22) ménagé dans le corps, les bras pivotant entre une position de préhension et une position de dégagement lorsque le piston avance dans le corps.
