ABSTRACT A drivable load-carrying roller assembly comprises a conveyor roller, roller-driving means at an end of the roller and a clutch disposed at that end for coupling the roller to the driving means and operable by linear displacement of means formed on or displaceable with a guard member shielding the said driving means. The guard member advantageously comprises a plate displaceable in a direction at right angles to the roller and provided with cam means engageable with one part of the clutch for shifting that part, in the axial direction of the roller, in relation to another clutch part, whereby the coupling of the roller to the driving means by the clutch is controlled. The said one clutch part may be spring- loaded towards its clutch-engaging position and movable to its clutch-disengaging position by the cam means or movable towards both its engaging position and its dis- engaging position by the cam means. The invention extends to conveyors comprising such roller assemblies actuated in unison.
