A platform adaptor for attachment to a support stand for supporting a large object such as a boat at dry dock includes a support beam which is pivotally connected to a center pole of the support stand and two support struts which extend downwardly from the support beam to attachment to two legs of the support stand such that the support beam will be generally horizontally oriented. A platform plank can be positioned on support beams of two platform adaptors attached to two spaced apart support stands to provide a platform for people and equipment located adjacent the supported object.
