the second connector comprising a second connector body having a second connector body column receiving end, a second connector body gusset contact end and a second connector body gusset contact face at the second connector body gusset contact end, wherein the second connector body gusset contact face has an opening ; and

at least a pair of second connector arms, each second connector arm being coupled to and extending from the second connector body and having a second connector arm inner face, a second connector arm outer face, a second connector arm gusset contact face, a second connector arm load bearing face and a second connector arm beam contact face, the beam contact face being positioned distal from the second connector body , and each second connector arm having at least one fixing aperture on the load bearing face for receiving a fastening means to couple the second connector to the first connector; and

a second connector arm boss coupled to and extending from the beam contact face of each arm, the boss having a second connector arm weld receiving bevel extending from the distal end of the arm and a second connector arm weld backer extending from the bevel;

the pin comprising a pin-body having a first end and an opposed second end, the first end adapted for coupling the aperture on the first connector body gusset contact face, and the second end adapted for engaging the opening on the second connector body gusset contact face;

wherein the pin further comprises a pin-hole formed on the pin body, and

wherein the pin is attachable to a shackle when the pin is not coupled to the second connector, and the pin is capable of forming a hoistable assembly with the first connector and the shackle.

2. The connector assembly of claim 1 , wherein the first end of the pin-body is threaded and engages a threaded aperture in the first connector body gusset contact face.

3. The connector assembly of claim 1 , wherein the opposed second end of the pin is conical.

4. A connector assembly comprising a first connector and a pin coupled to the first connector, the first connector comprising:

a first connector body having a first connector body column receiving end, a first connector body gusset contact end and a first connector body gusset contact face at the first connector body gusset contact end, wherein the first connector body gusset contact face has an aperture; and

at least a pair of first connector arms, each first connector arm being coupled to and extending from the first connector body and having a first connector arm inner face, a first connector arm outer face, a first connector arm gusset contact face, a first connector arm load bearing face and a first connector arm beam contact face, the beam contact face being positioned distal from the first connector body, and each first connector arm having at least one first connector arm fixing aperture for receiving a fastening means to couple a second connector to the first connector and at least one first connector arm gusset coupling aperture for receiving a second fastening means to couple the first connector to the gusset plate; and

a first connector arm boss coupled to and extending from the first connector arm beam contact face of each first connector arm, the boss having a first connector arm weld receiving bevel extending from a distal end of the arm and a first connector arm weld backer extending from the bevel;

the pin comprising a pin-body having a first end and an opposed second end, wherein the first end is adapted for coupling the aperture on the first connector body gusset contact face;

wherein the pin further comprises a pin-hole formed on the pin body, and

wherein the pin is attachable to a shackle, and the pin is capable of forming a hoistable assembly with the first connector and the shackle.

5. The connector assembly of claim 4 , wherein the first end of the pin-body is threaded and engages a threaded aperture in the first connector body gusset contact face.

6. The connector assembly of claim 4 , wherein the opposed second end of the pin is conical.
