1. A transportable platform system for loading and unloading freight, the transportable platform system comprising:
a transportable platform comprising:
a top surface comprising plastic or wood, the top surface including:
a plurality of perimeter stops attached to any portion of the top surface with screws;
a plurality of hooks positioned along a perimeter of the top surface, the plurality of hooks being configured to fasten to one or more nets;
at least two holes proximate a periphery of the platform configured to receive a bar code plate; and
a bottom surface opposite the top surface, the bottom surface comprising:
at least two frame support members mounted to the bottom surface, a first frame support member forming a front edge and a second frame support member forming a rear edge;
three support members, each support member spatially separated one from another and extending in parallel along the bottom surface from the first frame support member to the second frame support member, a first support member of the three support members forming a first side edge, a second support member of the three support members forming a second side edge, and a third support member of the three support members traversing a median of the platform;
four caster blocks attached to the bottom surface of the platform, wherein a first caster block is positioned proximate a first joint formed between the first support member and the first frame support member, a second caster block positioned proximate a second joint formed between the second support member and the first frame support member, a third caster block positioned proximate a third joint formed between the first support member and the second frame support member, and a fourth caster block positioned proximate a fourth joint formed between the second support member and the second frame support member;
two pivoting casters operatively coupled to the first caster block and the second caster block; and
two non-pivoting casters operatively coupled to the third caster block and the fourth caster block;
a carriage assembly operatively coupled to the bottom surface, the carriage assembly comprising:
a tow bar housing configured to house a first tow bar for a platform, the tow bar housing comprising:

a carriage link bottom plate comprising a bottom plate hole configured to engage the second tow bar via the second pop pin, wherein at least two guides are connected to and disposed between the carriage link top plate and the carriage link bottom plate and positioned to straddle a channel formed between the carriage link top plate and the carriage link bottom plate; and
a carriage link bar comprising a carriage link bar length extending from the tow bar housing to the carriage link top plate;
a tow bar comprising a tow bar length extending from a first end to a second end, the first end being configured to be slidably coupled to the tow bar housing via the first pop pin, the second end configured to be inserted between a carriage link top plate and a carriage link bottom plate of another transportable platform;
wherein tow bar comprises at least two hingedly connected sections extending along the tow bar length, a first section being connected to a second section via a hinge that comprises knuckles dovetailed together and comprising sloped ridges configured to limit rotation of the first section relative the second section;
wherein the tow bar housing of the carriage assembly is operatively coupled to the first frame support member and the third support member;
wherein the carriage link top plate is operatively coupled to the second frame support member and the third support member; and
wherein the carriage link bar extends along the third support member.
