• Elevator Spiders and FMS

    National Oilwell Varco's BJ products lead the industry in casing handling equipment by offering a wide range of casing tools, capable of handling casing sizes from 4 1/2" to 24 1/2" OD and with capacities of 350 to 1000 tons. Slip action is controlled by a conveniently positioned pneumatic control valve or by simple manual operation. All pneumatically controlled units operate by utilizing the rig air supply. For maximum crew safety the system may be manually operated if rig air pressure is temporarily lost. Further safety is insured by a positive locking mechanism that locks slips in the set position. The elevators utilize both a bottom guide and a bell guide to simplify stabbing. A top guide on spiders helps to centralize casing.
