Claim 15:
16. An apparatus, comprising:
a frame including a first end and a second end;
a conveyor mat including a proximal end coupled to the frame and a distal end spaced apart from the proximal end, the conveyor mat being configured to transition between a retracted state in which the distal end of the conveyor mat is located between the first end and a second end, and a deployed state in which distal end of the conveyor mat extends beyond the second end of the frame; and
a tensioning system including:
a handle,
a spool,
a cord at least partially wound about the spool and coupled to the conveyor mat, proximate to the distal end, and
a locking mechanism configured to disengage with the cord to permit the conveyor mat transitioning to the deployed state, and engage with the cord to prevent the conveyor mat transitioning to the deployed state.
