Claim:
An extendable conveyor comprising: a support structure; at least one extendable unit that is supported in a cantilevered manner and that is movable between an extended position and a retracted position nested within said support structure, said extendable unit having at least one support roller for rollingly engaging at least one of another extendable unit and said support structure as said extendable unit is extended or retracted; a plurality of conveying rollers rotatably supported at said at least one extendable unit, said plurality of conveying rollers defining a gravity operated conveying surface; and a braking device operable to limit rotation of at least one support roller via selective engagement of a braking element with said support roller, said braking device being activatable to disengage said braking element from said support roller in response to actuation of a user input, said braking device being biased to engage said braking element with said support roller when said braking device is deactivated.
