Wall Cantilever Series Jib Cranes
300 Series Wall Cantilever Jib Cranes

Wall Cantilever Jib Cranes

  • 200º rotation.
  • Offers greatest potential underboom clearance because it can be installed more closely to the ceiling than other wall mounted styles.
  • Two connection types:
  • A welded connection is used in most capacity and boom spans.
  • A bolted connection is used for larger spans and capacities because of shipping considerations. Stiffeners are welded to the mast at the point where the wall brackets are connected to stiffen the web of the I-beam.
  • Powered rotation is available on all models.
Hardware for mounting to wall or column supplied by others

Customers can fabricate their own Wall Cantilever Jib Crane using the hinge components supplied by SPANCO. All hardware for bolting the hinges to the jib are supplied.

Wall Bracket Tie Rod Supported Jib Cranes
Wall Bracket Tie Rod Supported Jib Cranes

Wall Bracket Tie Rod Supported Jib Cranes

  • 2000 degree rotation.
  • Utilizes a standard I-beam boom, a tie rod threaded at both ends, a fabricated beam bracket, and two wall brackets; one for the tie rod and one for the boom.
  • Allows maximum usage of the work area, including work close to the existing structure, because there are no supporting components under the boom.
  • This design is the most economical style of jib crane, provided overhead clearance or building column strength is not a limiting factor.
  • Hardware for mounting to wall or column supplied by others.

Wall Bracket Connection

  • Top and bottom wall brackets utilize a formed steel channel, with two bronze bushings, bronze thrust washers, and formed tie rod clevises.
  • All bolted connections are in double shear.
  • All swivel connections utilize bronze bushings and grease fittings to ease rotation, promoting long life and low maintenance.
