A transfer device includes an extendable transfer platform. The transfer platform includes a fixed plate, a moveable plate, and at least one platform actuator configured to selectively move the moveable plate relative to the fixed plate between a retracted position and an extended position in which a leading edge of the moveable plate is located distally from a leading edge of the fixed plate. The transfer platform also includes a transfer belt having a first end secured to a first driven roller, and a second end secured to a second driven roller. The transfer device also includes a platform support structure secured to the transfer platform for supporting the transfer platform above a floor surface. The platform support structure includes at least one support actuator configured to selectively move the transfer platform relative to the floor surface between a lowered position and a raised position.

An example rail wheel chain conveyor includes a first rail spaced apart from a second rail to form a transport area therebetween. A conveyor belt is configured in the transport area as a loop for moving along a continuous path. A plurality of rocker arms are spaced apart from one another and configured to support the conveyor belt. Rail wheels on each side of the rocker arms ride on the rails. A chain is mounted to an underside of the conveyor belt by being rigidly attached to the rocker arm. The example rail wheel chain conveyor includes a primary drive system having a primary chainring mounted on a drive shaft and engaging with the chain, and a primary drive motor to rotate the drive shaft, thereby rotating the chainring and moving the conveyor belt along the continuous path.

Disclosed herein is a conveyor system that includes: a plurality of elongate rib elements coupled in a spaced transverse configuration atop a pair of chassis rails, each of the rib elements defining an elongate through opening; a planar support element coupled atop the rib elements, for supporting a portion of the conveyor belt assembly; a conveyor belt assembly having a conveyor belt, a plurality of transverse belt support elements coupled across a plurality substantively parallel lengths of conveyor chains, and the conveyor belt; whereby the planar support element is sized to enable a path for the conveyor belt system when formed in continuous loop configuration being returned through the apertures defined in each rib element; and a pair of transverse axles operating about each end of the conveyor assembly, each axle having a gear for engaging a respective chain, wherein one axle is driven to move the conveyor belt assembly.

A conveyor idler replacement system in one example with an H-frame (support frame). The system including a base with a first vertical strut extending from the base, a second vertical strut extending substantially vertically from the base; each of the first vertical strut and second vertical strut comprising a first idler frame bracket on a first longitudinal side of the H-frame; a first idler frame extending between the first idler frame bracket on the first vertical strut and the first idler frame bracket on the second vertical strut; at least one idler attached to the first idler frame, the idler configured to rotate, configured to support a conveyor belt. Including a system for lifting the belt and replacing idler frames.
