An endless belt conveyor for heavy materials handling is provided in which shock forces generated by the loading of heavy objects onto the conveyor are absorbed in the vertical, longitudinal and lateral directions with respect to the conveyor by resilient suspension means such as a plurality of rubber shear spring blocks which are associated with the support structure for the track upon which the conveyor belt moves. The belt is comprised of slat links having a central transverse reinforcing beam and slat link covers surrounding the transverse reinforcing beam which converge to either side of the beam at a point intermediate the vertical distance between the top and bottom portions of the beam. Material loaded on top of the conveyor slat links contacts the higher portion of the slat link at the portion of the slat link where the beam is located, the beam acting to distribute the shock from the material loaded thereon along its length and to transmit such shock loadings to the conveyor support structure which absorbs the shock.
A conveyor comprising:
A conveyor comprising:
In a conveyor having an endless conveyor belt travelling along a pair of longitudinally extending conveyor tracks, a plurality of supports comprising a series of spaced, parallel support stations on opposite sides of said conveyor;
A conveyor comprising an endless conveyor belt traveling along a pair of longitudinally extending conveyor tracks, a plurality of track support means spaced along the conveyor on opposite sides thereof with the support means on one side of said conveyor disposed opposite respective ones of said support means on the other side of said conveyor to form associated pairs thereof, each of said track support means comprising a pair of upstanding and rigidly interconnected support members spaced apart longitudinally of the conveyor, a plurality of transverse track support beams extending laterally of the conveyor below the said conveyor tracks and spaced apart longitudinally of the conveyor, said support beams passing at their opposite ends between the support members of respective pairs or said support means, each of said support means having a set of rubber shear blocks each secured at one of their opposite shear face sides to said support means and at their other shear face sides to the opposite sides and end, respectively, of the associated transverse track support beam to resiliently support it in place and absorb shock loadings on the conveyor in the vertical, lateral and longitudinal directions relative to the length thereof, and a plurality of pairs of track supporting rubber shear blocks resiliently supporting said conveyor tracks on respective ones of said transverse support beams, the rubber shear blocks of each said pair thereof being disposed adjacent and on opposite sides of a respective one of said conveyor tracks and having their opposite side shear faces respectively secured to the said one conveyor track and to the said respective one of said support beams to absorb shock loadings on the conveyor in both the vertical and longitudinal directions relative to the length of the conveyor.
A conveyor comprising an endless conveyor belt travelling along a pair of longitudinally extending conveyor tracks, a track supporting sub-frame assembly disposed below said tracks and comprising a plurality of transverse track support beams extending transversely of said conveyor in spaced apart relation along the length thereof and rigidly interconnected by a plurality of longitudinally extending connecting beams, a series of support stations spaced along opposite sides of said conveyor and each comprising a pair of vertical support members, resilient means mounting the end portions of each of said transverse support beams on respective pairs of said support members to floatingly suspend the said sub-frame assembly therefrom and absorb shock loadings on said conveyor in the lateral, longitudinal and vertical directions, and secondary resilient means mounting the conveyor tracks on said transverse support beams to absorb shock loadings on said conveyor in both the vertical and longitudinal directions.
