The conveyor includes a conveying surface for conveying articles extending at least partially on an upper side of the mechanically extendable section. The mechanically extendable section is an outmost mechanically extendable section and the outmost mechanically extendable section has a modular front end portion which can carry a loading set and an unloading set. ## Claims ### Claim 1 An extendable conveyor for conveying articles, said conveyor comprising: a base unit; a mechanically extendable section supported in a cantilevered manner and selectively positionable relative to the base unit; and a conveying surface to convey articles, the conveying surface extending at least partially on an upper side of the mechanically extendable section, wherein the mechanically extendable section is an outmost mechanically extendable section including a modular front end portion that is selectively configurable to incorporate at least one of a loading set or an unloading set, wherein the conveying surface is to be spaced apart from the end of the outmost mechanically extendable section in a loading configuration of the modular front end portion and to extend to the end of the outmost mechanically extendable section in an unloading configuration of the modular front end portion. ### Claim 2 (depends on 1) The extendable conveyor of claim 1, wherein the loading set includes at least one of a loading plate, a debris tub and a roller. ### Claim 3 (depends on 1) The extendable conveyor of claim 1, wherein the unloading set includes at least one of a front plate and a shock absorbing system. ### Claim 4 (depends on 3) The extendable conveyor of claim 3, wherein the shock absorbing system comprises a shock absorber. ### Claim 5 (depends on 1) The extendable conveyor of claim 1, wherein the modular front end portion includes a safety bumper. ### Claim 6 (depends on 1) The extendable conveyor of claim 1, wherein the modular front end portion comprises a side bar to carry at least portions of the loading set or the unloading set. ### Claim 7 An extendable conveyor for conveying articles, said conveyor comprising: a base unit; a mechanically extendable section supported in a cantilevered manner and selectively positionable relative to the base unit; and a conveying surface to convey articles, the conveying surface extending at least partially on an upper side of the mechanically extendable section, wherein the mechanically extendable section is an outmost mechanically extendable section including a modular front end portion that is selectively configurable to incorporate at least one of a loading set or an unloading set, wherein the modular front end portion is to carry a side part including an input to control the extendable conveyor. ### Claim 8 (depends on 7) The extendable conveyor of claim 7, wherein the side part is to receive a multi-connector to connect at least one of lighting, an air blower or a lift arrangement. ### Claim 9 An extendable conveyor for conveying articles, said conveyor comprising: a base unit; a mechanically extendable section supported in a cantilevered manner and selectively positionable relative to the base unit; and a conveying surface to convey articles, the conveying surface extending at least partially on an upper side of the mechanically extendable section, wherein the mechanically extendable section is an outmost mechanically extendable section including a modular front end portion that is selectively configurable to incorporate at least one of a loading set or an unloading set, wherein the conveying surface includes a belt, the belt is guided over a reversing roller located in the modular front end portion, and the modular front end portion is to carry the reversing roller in a loading position and in an unloading position. ### Claim 10 An extendable belt conveyor for conveying articles, the conveyor comprising: a base unit; a mechanically extendable section supported in a cantilevered manner and selectively positionable relative to the base unit; and a conveying surface including a belt to convey articles extending at least partially on an upper side of the mechanically extendable section; wherein one of the mechanically extendable section is an outmost mechanically extendable section including a modular front end portion, the belt is guided over a reversing roller located in the modular front end portion, and the modular front end portion is to selectively carry the reversing roller in at least one of a loading position or an unloading position, the reversing roller being located closer to the outmost end of the outmost mechanically extendable section in the unloading position than in the loading position. ### Claim 11 (depends on 10) The extendable belt conveyor of claim 10, wherein the modular front end portion is to support at least one of a loading set or an unloading set. ### Claim 12 (depends on 10) The extendable belt conveyor of claim 10, wherein the loading set includes at least one of a loading plate, a debris tub and a roller. ### Claim 13 (depends on 10) The extendable belt conveyor of claim 10, wherein the unloading set includes at least one of a front plate and a shock absorbing system. ### Claim 14 (depends on 10) The extendable belt conveyor of claim 10, wherein the conveying surface is spaced apart from the end of the outmost mechanically extendable section in a loading configuration of the modular front end portion and extends to the end of the outmost mechanically extendable section in an unloading configuration of the modular front end portion. ### Claim 15 (depends on 10) The extendable belt conveyor of claim 10, wherein the modular front end portion is to carry a side part including an input to control the extendable conveyor. ### Claim 16 (depends on 15) The extendable belt conveyor of claim 15, wherein the side part is to receive a multi-connector to connect at least one of lighting, an air blower, or a lift arrangement. ### Claim 17 (depends on 10) The extendable belt conveyor of claim 10, wherein the modular front end portion is to carry a safety bumper. ### Claim 18 (depends on 10) The extendable belt conveyor of claim 10, wherein the modular front end portion comprises a side bar to carry at least parts of the loading set or the unloading set.
