1. An extension arm accessory unit for a drywall crane fork assembly, said extension arm accessory unit comprising:
a mounting bracket having a top wall and bottom wall interconnected by a first sidewall to define a generally C-shaped arrangement, wherein said top wall and bottom wall extend parallel to each other and said first sidewall is perpendicular to said top and bottom walls;
a removable second sidewall releasably attached to said mounting bracket, wherein said second sidewall extends between said top wall and said bottom wall in a perpendicular arrangement opposite said first sidewall;
a tensioning member carried by said second sidewall for biasing against a fork carrier beam when mounted to draw said first sidewall against said fork carrier beam to secure said mounting bracket to the beam;
an extension arm port carried on an exterior side of said first sidewall, wherein said extension arm port includes a port top wall, a port bottom wall and a port sidewall interconnecting said port top and port bottom walls to define a hollow interior extending along an axis parallel to a length of said first sidewall;
an extension arm carried in said extension arm port, wherein said extension arm has a generally L-shaped arrangement with a first arm portion adjustably carried in said extension arm port, and a second arm portion disposed at a distal end of said first arm portion and extending perpendicular to said first arm portion;
whereby said mounting bracket is removably mountable around a fork carrier beam and provides said extension arm extending in an adjustable arrangement perpendicular to lifting forks of the drywall crane fork assembly to assist with sliding drywall off the fork assembly over an extended distance.
