How to Install a Jib Hoist Base
Jib cranes are used in indoor and outdoor construction to lift and move materials weighing between 500 and 10,000 pounds, depending on the size of the crane. When heavy materials are lifted, you want to ensure your jib crane remains seated on the floor or ground. Installing a jib hoist base to hold the crane in place is the solution. The column assembly of the jib crane is bolted to a concrete base with embedded anchor bolts. If installed properly, the crane will still turn in a 360-degree rotation. Does this Spark an idea?
