a locking means for releasably locking at least one of the support beams in the operative position; and wherein at least one of the support beams is displaceable relative to the frame between the operative position and the removable position. ### Claim 2 (depends on 1) The conveyor roller support arrangement as claimed in claim 1, in which each of the support beams comprises a recess for receiving an axle of the conveyor roller for rotation. ### Claim 3 (depends on 2) The conveyor roller support arrangement as claimed in claim 2, in which the locking means comprises an at least one locking recess positioned in an operatively lower edge of at least one of the support beams, the respective locking recess being engageable with a boss arranged on at least one of the pair of opposed end-frames. ### Claim 4 (depends on 3) The conveyor roller support arrangement as claimed in claim 3, in which the locking means comprises a series of locking recesses spaced longitudinally on at least one of the support beams to enable the respective support beam to be used to control the an orientation of a rotation axis of the conveyor roller supported by the conveyor roller support arrangement, thereby to assist in a control of a tracking and an alignment of a conveyor belt supported by the conveyor roller support arrangement. ### Claim 5 (depends on 4) The conveyor roller support arrangement as claimed in claim 4, in which the series of locking recesses vary progressively in depth, to enable at least one of the support beams to be used to control the orientation in two planes of the rotation axis of the conveyor roller supported by the conveyor roller support arrangement, thereby to assist in the control of the tracking and the alignment of the conveyor belt supported by the conveyor roller support arrangement. ### Claim 6 (depends on 1) The conveyor roller support arrangement as claimed in claim 1, further comprising a support device configured to support the conveyor roller when free for removal from the frame comprising a jack-mounted cradle. ### Claim 7 (depends on 1) The conveyor roller support arrangement as claimed in claim 1, further comprising a belt-lifting device configured to lift a conveyor belt clear of the conveyor roller removably mounted on the frame. ### Claim 8 A conveyor roller support arrangement comprising: a pair of opposed end-frames within a frame, each of the pair of opposed end-frames comprising a support beam configured to mount a respective end of a conveyor roller; a support device configured to support the conveyor roller when free for removal from the frame comprising a jack-mounted cradle; and wherein at least one of the support beams is displaceable relative to the frame between an operative position in which the conveyor roller is mounted for rotation and a removable position in which the conveyor roller is free for removal from the frame. ### Claim 9 (depends on 8) The conveyor roller support arrangement as claimed in claim 8, in which the support device further comprises a fixedly mounted cradle spaced laterally with respect to the frame from the jack-mounted cradle. ### Claim 10 (depends on 9) The conveyor roller support arrangement as claimed in claim 9, further comprising a lateral guide channel with which the support device is slidably engaged for lateral displacement with respect to the frame. ### Claim 11 (depends on 10) The conveyor roller support arrangement as claimed in claim 10, in which the support device is removable from the frame. ### Claim 12 (depends on 8) The conveyor roller support arrangement as claimed in claim 8, further comprising a locking means for releasably locking at least one of the support beams in the operative position. ### Claim 13 (depends on 12) The conveyor roller support arrangement as claimed in claim 12, in which the locking means comprises an at least one locking recess positioned in an operatively lower edge of the respective support beam, the respective locking recess being engageable with a boss arranged on at least one of the pair of opposed end-frames. ### Claim 14 (depends on 8) The conveyor roller support arrangement as claimed in claim 8, wherein ends of at least one of the support beams are received within a plurality of slots defined in at least one of the pair of opposed end-frames so that the respective support beam is operable for lateral displacement within the plurality of slots to displace the respective support beam from the operative position to the removable position. ### Claim 15 (depends on 14) The conveyor roller support arrangement as claimed in claim 14, in which each of the support beams comprises a recess for receiving an axle of the conveyor roller for rotation. ### Claim 16 A conveyor roller support arrangement comprising: a pair of opposed end-frames within a frame, each of the pair of opposed end-frames comprising a support beam configured to mount a respective end of a conveyor roller; a belt-lifting device removably mounted on the frame configured to lift a conveyor belt clear of the conveyor roller; and wherein at least one of the support beams is displaceable relative to the frame between an operative position in which the conveyor roller is mounted for rotation and a removable position in which the conveyor roller is free for removal from the frame. ### Claim 17 (depends on 16) The conveyor roller support arrangement as claimed in claim 16, in which the belt-lifting device comprises a plurality of parallel beams pivotally connected to each other by a plurality of cross members such that the plurality of parallel beams are operable, while remaining parallel, to be spaced more or less closely to each other, in a parallel rule-like manner. ### Claim 18 (depends on 16) The conveyor roller support arrangement as claimed in claim 16, further comprising a locking means for releasably locking at least one of the support beams in the operative position. ### Claim 19 (depends on 16) The conveyor roller support arrangement as claimed in claim 16, wherein ends of at least one of the support beams are received within a plurality of slots defined in at least one of the pair of opposed end-frames so that the respective support beam is operable for lateral displacement within the plurality of slots to displace the respective support beam from the operative position to the removable position. ### Claim 20 (depends on 19) The conveyor roller support arrangement as claimed in claim 19, in which each of the support beams comprises a recess for receiving an axle of the conveyor roller for rotation.
