BVM Casing Spiders and/ Elevators are time tested designs made in our Magnolia, Texas USA factory of high quality alloy steel. They are 100% load tested and MPI inspected and certified to API 8C specifications. They are all “clam shell” designs so that by removing one hinge pin the unit can be opened to easily install it on or remove it from an in place string. The 250 ton model is available as either manual or pneumatic. Used in a set of one elevator and one spider they allow the string to be rapidly “tripped” in or out of the well with a minimum of manual interaction by the operator. our wide range of sizes and lifting capacities assures that there is a Spider / Elevators set for nearly all applications.
