A line shaft conveyor is a conveying unit that is driven by a shaft under a bed of rollers. These conveyors are suitable for light applications up to 50kg, such as cardboard boxes and tote boxes.
A single shaft runs underneath and perpendicular to a bed of rollers, running the entire length of the conveyor module. The shaft is populated with a number of spools equal to the number of rollers above, with one spool for each roller. Each Siyamuva grooved roller is connected to the shaft and spool by means of an O-ring. The O-ring acts as the driving mechanism to turn the roller when the shaft is powered – as the rollers rotate, they move the product on the rollers in the direction of travel. The shaft is driven by an external motor/gearbox, the speed and kW of which is determined by the load and throughput required.
The Siyamuva line shaft conveyor offers low pressure accumulation, so products will make contact with each other on the line. The contact is kept to a minimum due to the spool acting as a clutch on the shaft and rotating when under too much pressure.

Advantages of this conveyor include quiet operation, easy installation, moderate maintenance, and low expenses. Line-shaft conveyors are also extremely safe for people to work around, as the elastic belts can stretch in order to not injure fingers should any get caught underneath them. Moreover, the spools will slip and allow the rollers to stop moving if clothing, hands or hair gets caught in them. The spools are also slightly loose on the shaft, acting like clutches that slip when products are required to accumulate (stop moving and bump up against each other; queue up).
With the exception of soft bottomed containers like cement bags, these conveyors can be utilised for almost all applications.
A disadvantage of the line shaft conveyor is that it can only be used to convey products that span at least three rollers, but rollers can be as small as 17mm in diameter and as close together as 18.5mm. For items shorter than 74mm, the conveyor belt system is generally used as an alternative option.
