1. A fall protection system comprising:
a base plate defining a first side and a second side defined opposite to the first side, the base plate comprising one or more ports configured so that the base plate is receivable by a conveying apparatus;
a mast assembly rotatably connected to the base plate proximate to the first side of the base plate so that the mast assembly is rotatable relative to the base plate and to a counterweight connected thereto, about an axis of rotation that is aligned with a long axis of the mast assembly;
a jib inclined with respect to the mast assembly and pivotably connected to the mast assembly; and
a counterweight connectable to the base plate proximate to the second side of the base plate, wherein a center of gravity of the counterweight is offset from a center of the base plate.
