A conveyor belt idler support includes a fixed frame having support idlers for a return path of the belt. A movable frame is mounted on the fixed frame and is tiltable to support the carrying portion of the belt with a varying degree of tilt to allow the belt extend in a curved path around corners. The fixed frame has a projecting bracket carrying support rollers which extends into a hollow box portion at the center of the movable frame adjacent the middle to support most of the load on the movable frame. The movable frame has a center section and outwardly and upwardly sloping side sections each carrying idlers to define a trough for the belt. At one side, the movable frame carries a upwardly extending guide roller to limit lateral movement of the belt and allow the belt to apply a lateral force to the movable frame to tilt it about the support roller. At the other side is a fixed rigid link pivotally secured to both the support frame and the movable frame which is rotatable as the movable frame moves sideward to cause the frame to tilt in a controlled manner to achieve the desired tilt angle for the belt.

An endless belt conveyor including an independently supported first support pulley vertically and laterally displaced from a second support pulley. An endless belt including bulk material carrying compartments entrained around the first and second support pulleys and which is engaged by the full width of said support pulleys. The endless belt includes a radius of curvature near the top of the vertical run of a predetermined size such that the bulk material carried in the endless belt is not expel due to centrifugal force. A portion of the endless belt entrained over the first support pulley has a radius of curvature of a predetermined size such that the material carried in the endless belt is expelled due to centrifugal force.

An improved belt supporting and guiding apparatus enabling belt travel in other than a linear path wherein there is a base frame and a second frame mounted on the base frame; the second frame has center, left and right portions with surfaces which together define a belt support surface delimiting a concavity that is shaped other than as a constant arc of a circle so that rotation of the second frame on mounting rollers is about an instant center whose spatial location changes constantly.

The invention relates to an advancing tailpiece of a continuous belt conveyor system used in the mining industry. The advancing tailpiece is supported by telescopic booms extending from a support structure rising from the base of a tow car. The telescoping booms are pivotally connected to the support structure and the advancing tailpiece. The advancing tailpiece further includes a mechanical arm pivotally connected to the advancing tailpiece and having a telescopic boom. Carrying idler assemblies are loaded on the mechanical arm which is used to position the carrying idler assembly for attachment to an intermediate conveyor section of the continuous belt conveyor.
