About Sleeve Insert Jib Cranes
Sleeve Insert Mounting: a second reinforced foundation is poured into the existing building slab. The foundation pour consists of an initial pour in which anchor bolts are embedded into the concrete through the sleeve insert base plate.
Once the sleeve insert is in place, the rest of the foundation is poured around the sleeve insert, providing the appropriate weight and size to anchor and counterbalance the crane when under maximum load.
Typical foundation sizes range from 3 ft. deep by 4 ft. square to 5 ft. deep by 11 ft square.
