This paper presents the design of a cradle for mounting solar energy concentrator dishes. The cradle is strong and provides unobstructed space to mount a well braced dish. It will survive high winds without being driven to a stow position. The axes of rotation of the dish pass near the plane of the edge of the dish to reduce wind-induced torques in the drive system. Large radius tracks are attached to both the dish and cradle so the gear train on the drive motors can be simple and inexpensive. The cradle is a strong gimbal mount built of 12 structural members in the form of three tetrahedra. It provides a polar axis mount for the concentrator dish. All forces parallel to the polar axis are delivered to the earth at the end of the cradle closest to the equator.
