ABSTRACT:
An upper coupler table for facilitating the removal of an upper coupler plate from a semitrailer. The upper coupler table includes a support frame which supports a jack and a guide tube. A vertically adjustable center plate has a support tube attached thereto which extends through the guide tube. The jack contacts the support tube and can be operated to raise the center plate to a position where it can support the upper coupler plate while the upper coupler plate is detached from the semitrailer. After the upper coupler plate has been detached, the jack can be operated to lower the center plate until the upper coupler plate is supported on the support frame. The upper coupler table includes a plurality of casters attached to the support frame, allowing the table to be easily moved.
