Systems, methods and articles of manufacture are disclosed for effecting a desired collective operation on a parallel computing system that includes multiple compute nodes. The rotational torque transmission path has uses an electromagnetic brake delay rotation of a drum, which is coupled to the rotary crank body by a biasing member and a moving member. The floor also being capable of moving down to a lowered position to provide a trailer with an approximately even floor and a full-height ceiling throughout. The apparatus also includes a microprocessor for the comparing of the captured values of the at least one delivery end sensor to those of at least a second draw frame operational mode, whereby the second draw frame operational mode does not represent the normal operational mode of the draw frame machine.
