A conveyor employs a low-tension, direct drive conveyor belt, and a snap-on position limiter for ensuring proper engagement of the belt and a drive sprocket. The position limiter includes a body, a limiting surface and a snap clap opposite the limiting surface for snapping the position limiter to a mounting shaft. The position limiter may include a mounting arm for mounting a conveyor belt scraper at the front of the position limiter. Mounting plates at the end of the conveyor support a mounting shaft for mounting the position limiter or other conveyor components in place relative to the drive sprocket.

A conveyor mechanism and system are described that provide for conveyance of objects from a first position to a second position. The conveyor mechanism includes a torus-shaped flexible membrane having a central axis, the torus-shaped flexible membrane elongated along a direction parallel to the central axis and having an external surface, center channel, and an enclosed cavity. The conveyor mechanism also includes a first roller assembly disposed within the enclosed cavity of the torus-shaped flexible membrane, a second roller assembly that applies a force against the external surface and the first roller assembly to cause the torus-shaped flexible membrane to rotate longitudinally around the enclosed cavity to convey objects along the center channel, and an adjustment device that adjusts a position of the second roller assembly along a direction parallel with the central axis.

A handrail drive for driving a handrail of a person-transporting device has at least one drive device and at least one counterpressure device. The counterpressure device contains at least one loading device and at least two counterpressure rollers, wherein the handrail can be guided between the drive device and the counterpressure device. The counterpressure rollers load the handrail against the drive device by a pressing force caused by the preloading force of the loading device. At least one flexible pulling element is arranged between the at least one counterpressure roller and the loading device, by which flexible pulling element the preloading force of the loading device can be transferred to the at least one counterpressure roller.

A drive system for a paddle belt conveyor comprises a drive shaft and a drive roller rotationally driven by the drive shaft about a first axis. The drive roller exerts traction on a belt of the belt conveyor. The belt comprises a plurality of paddles. The drive system includes a pinch roller mounted rotationally about a second axis parallel to the first axis. The pinch roller pinches the belt between the pinch roller and the drive roller to augment the traction of the drive roller on the belt. Either the drive roller or the pinch roller is a bobbin roller to accommodate the paddles on the belt. The drive system may further include a take-up roller rotatable about a third axis parallel to the first axis, and first and second idler rollers rotatable about fourth and fifth axes parallel to the first axis.

The disclosure relates to a drive arrangement for driving a belt of an enclosed belt conveyor. The disclosure further relates to a mobile haulage arrangement for continuously conveying fragmented material in a conveying direction and to a method for driving a mobile haulage arrangement. The drive arrangement for driving a belt of an enclosed belt conveyor include a conveyor drive assembly arranged to drive the belt of the conveyor run in the conveying direction, and a return drive assembly arranged to drive the belt of the return run in an opposite direction.

A belt and a belt conveyor are provided for transporting particulate material and especially oilseeds up the belt conveyor. The belt conveyor can include an intake end having a hopper, a discharge end, a body extending between the intake end and the discharge end and a belt. The belt travels along a travel path in the belt conveyor; the belt traveling through the hopper, up an upper run in the body to the discharge end, down a return run in the body, and back through the hopper. The belt can have a top surface having pairs of adjacent ridges provided on the top surface, each ridge having a pair of arms extending from a point, in a travel direction of the belt, wherein each pair of adjacent ridges define a v-channel on the top surface of the belt.
