  • Publication number: 20140353127
    Abstract: This invention relates to an idler roller (1) for a belt conveyor and an idler roller assembly (41). The idler roller (1) comprises an elongate static shaft (3), a rotatable drum (5) mounted about and substantially surrounding the static shaft (3) and at least one bearing (7, 9) intermediate the shaft (3) and the rotatable drum (5). The idler roller (1) further comprises a load cell mounted on the static shaft internal the rotatable drum (5). The static shaft comprises a load cell section that is weakened relative to the remainder of the shaft. By having such an idler roller, the idler roller will have the means necessary to weigh the materials passing over a conveyor (65) supported by the idler roller thereby obviating the need for a sub frame and a lengthy installation of weighing idler roller assembly.
