ABSTRACT:
In accordance with certain preferred aspects of the present invention, there is provided tree running tool with a mechanical mechanism for unlatching the tree running tool from a side valve tree. The tree running tool is formed from a tool body, a stem, a telescoping element, a retractable spacer, a means for moving the spacer, and a means for attaching the telescoping element to a lift device. The tool body has an upper end, a lower end, and a longitudinal axis. The stem is fixedly attached to the upper end of the tool body and extends axially therefrom. The stem has a lower end attached to the tool body and a generally annular flange at a position spaced apart from the tool body. The telescoping element is positioned alongside the stem. The telescoping element has a generally annular flange at a position between the generally annular flange of the stem and the tool body. The retractable spacer is movable from an engaged position between the generally annular flange of the stem and the generally annular flange of the telescoping element, in which the spacer spaces the generally annular flange of the stem apart from the generally annular flange of the telescoping element, to a retracted position in which a void is formed between the generally annular flange of the stem and the generally annular flange of the sleeve. The means for moving the spacer is mounted to the tool body and the spacer for moving the spacer from the engaged position to the retracted position. The means for attaching the telescoping element to a lift device is mounted to the telescoping element.
