Abstract
A sling belt conveyor has a pair of individually tensioned cables (209, 224) with transverse slings (51) pivotally connected to the cables (209, 224) which support a low tension conveyor belt (61) without being connected thereto. The belt (61) extends beyond the path of the support cables (209, 224) and is tensioned independently of the latter.
Claims11
A conveyor including a pair of endless support cables each having a forwarding run and a return run between longitudinally spaced tail and head ends of said conveyor, said forwarding runs being substantially coextensive and situated at substantially the same elevation and support means supporting said support cables for respective movement along endless paths described by said support cables, said conveyor characterized by
- a plurality of transverse slings arranged at longitudinally spaced intervals along said endless support cables each sling including an intermediate flexible transverse strap and a pair of relatively rigid hangers with first corresponding ends connected, respectively, to the opposite transverse ends of said strap and second corresponding ends pivotally connected, respectively, to said support cables at fixed transversely aligned points therealong for pivotal movement about axes transverse to the axes of said cables,
- an endless flexible conveyor belt having a working run and a return run said working run being supported without attachment on said straps in the forwarding run of said support cables,
- end rollers supporting said endless belt at the opposite ends of said conveyor, and
- intermediate rollers at spaced intervals supporting the return run of said conveyor belt.
A conveyor including a pair of endless support cables each having a forwarding run and a return run between longitudinally spaced tail and head ends of said conveyor, said forwarding runs being substantially coextensive and situated at substantially the same elevation and support means supporting said support cables for respective movement along endless paths described by said support cables, said conveyor characterized by
- a plurality of transverse slings arranged at longitudinally spaced intervals along said endless support cables, each sling including an intermediate flexible transverse strap and a pair of rigid hangers with first corresponding ends connected, respectively, to the opposite transverse ends of said strap for pivotal movement about longitudinally disposed axes and second corresponding ends pivotally connected, respectively, to fixed transversely aligned points on said support cables by pivot means for pivotal movement relative to said cables, and
- an endless flexible conveyor belt having a working run and a return run, said working run being supported by said straps without attachment thereto in the forwarding run of said support cables.
