Question 26

what are the functions of the cradle

Answer 26

1. The function of the Trunnions are to absorb some of the recoil shock and allow the barrel to be raised and lowered for aiming 2 The cradle provides movement in the vertical plane in relation to the saddle 3 The function is to support the ordnance and recoil mechanism 4 The cradle is fitted with trunnions that are housed in bearings on the saddle and held down by cap squares
