Abstract
A telescoping, adjustable length tool basket, particularly suitable for offshore operations in the oil and gas industry. A center section has four elongated, tubular corner members, joined by bottom and side members. At least one, and preferably two, wing sections comprise elongated inner corner members that are slidably disposed within the outer corner members. The wing sections can be moved inwardly and outwardly from the center section to adjust the overall tool basket length to accommodate the tool length. When adjusted to the desired length, a lock pin is inserted through aligned holes in at least one pair of outer and inner corner members, to lock the tool basket at the desired length. Inner and outer bushings are disposed in the annulus between the inner and outer corner members. Preferably the bushings are of a polytetraflouroethylene (PTFE) material such as Teflon®.
