摘要： An extendable conveyor includes a support structure, and 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 the support structure. The extendable unit has at least one support roller for rollingly engaging at least one of another extendable unit and the support structure as the extendable unit is extended or retracted. The conveyor includes a braking device operable to limit rotation of at least one support roller via selective engagement of a braking element with the support roller. The braking device is activatable to disengage the braking element from the support roller in response to actuation of a user input. The braking element is biased to engage the braking element with the support roller when the braking device is deactivated.

摘要： An extendable conveyor includes a support structure, a mechanically extendable section which is extendable along the longitudinal axis between a fully retracted position and a fully extended position, a conveyor belt reeved among the mechanically extendable section thereby defining a conveying surface and a drive. The drive is operable to drive the conveyor belt in at least one direction. The extendable section may be extended by driving the conveyor belt in one direction and retracted by driving the conveyor belt in an opposition direction. The mechanically extendable section may include a plurality of sections at least one made substantially from a unitary sheet of material.
