ABSTRACT In a jaw-type rock crusher having a stationary jaw and a cantilevered swing jaw, an enlarged, unobstructed top feed opening with protected swing jaw hinge supports is provided by attaching the upper lateral support arms of the crusher's swing jaw to two preferably single shear hinge supports laterally disposed on either side of the top feed opening. The stationary jaw and swing jaw of the crushing apparatus are supported in a stationary frame having side panel structures which extend upward from the area of the crushing chamber to the height of the swing jaw hinge axis so as to cover the hinge supports of the swing jaw. Preferably the rearward extent of the top feed opening is delineated by a shock-absorbing backwall hingedly attached to the stationary frame behind the swing jaw's hinge supports so that the impact forces of crushable materials fed into the crushing apparatus are absorbed by the backwall.
