Texas International Oilfield Tools's Hinged Casing Spiders are used during casing handling operations when cementing equipment will not clear a closed spider or rotary table, casing will not pass or clear a closed spider or rotary table, or where it is preferred to not place heavy casing string loads directly on rotary table bearings.
The FMS 375 is mounted flush with the rig floor, allowing the casing connection height to be lowered 1 meter (3 feet), thus eliminating the need for scaffolding.
