The cradles are designed to be located at transfer points of receiving conveyors, under the hopper and chute box, close to the tail pulley. Depending on the force of the discharged material, they can possess different structural qualities. All three Martin Impact Cradles feature wing supports, which adjust to match CEMA standard trough angles, as well as a five per cent fine-tuning adjustment angle. This allows for the cradle to accommodate the idler profiles of different manufacturers. The Martin Impact Cradle HD is designed to withstand impact forces from 12,000 to 17,000 lbf. (53.4 to 75.6 kN) and drop heights of light material up to 50 feet (15.2 m). Classified as Heavy-Duty (H) in CEMA Standard 575-2000, it fits E-6 and E-7 conveyor configurations. Support beams in the centre of the cradle are set 3/4” (19 mm) below the receiving belt’s line of travel, allowing the belt to avoid sustained friction when running empty, yet absorbing significant impacts during loading while still retaining a tight seal. The unit is equipped with 7 to 13 heavy-duty impact bars, depending on width. Installed perpendicular to the belt path, the bars are reinforced by a steel support structure with a base of impact-absorbing 50-durometer styrene-butadiene (SBR) rubber and a top layer of slick UHMW plastic. They are engineered to withstand dynamic energy and a heat range of -20° to 140°F (-29° to 60°C) without com-promising the structural integrity of the conveyor frame. The cradle is on a Trac-Mount, allowing it to slide out for bar replacement The Martin Impact Cradle MD is designed for medium duty applications, suit-able for use with belts traveling up to 1,000 ft/min (5 m/s). Mounted on four steel I-beam supports, the cradle is able to sustain a maximum weight of 12,000 ft/lbs (53.4 kN) with light material drop heights up to 26 ft. (7.9 m).
