Base mount jib cranes also go by the names of floor mount jib cranes or free standing jib cranes. These cranes are typically installed onto a concrete footing, thus not applying a load to the building columns. Base mount jib cranes are fitting for applications which are not near building columns or require large capacities or spans. This style of jib crane can also be mounted into a sleeve which is installed on top of the floor or recessed into the floor. Capacities are available up to 15 Tons, spans up to 50’, and up to 40’ to the underside of boom. Rotation is 360 degrees.
Mast or pillar jib cranes are used when there is not an adequate building column nearby. The mast of the jib crane is connected to the floor and to the overhead support steel. They do apply forces to the building but those forces often require less reinforcement steel than a tie-rod style or cantilever jib crane. Standard sizes vary up to 5 Tons, up to 20’ span, and up to 20’ to the underside of boom. Custom projects can be larger scale. Rotation is 360 degrees.
