CUSTOM JIB CRANES 


Telescoping Jib Crane

telescoping jib crane
This is a top and bottom supported jib crane that telescopes. These jib cranes are particularly useful when ceiling height is limited. They can be mounted to a wall or column within three inches of the ceiling, providing valuable additional inches of lifting range. Entirely self-supporting, without tie rods or other bracing, the jib crane can be installed with the girder at maximum available height and with very little clearance necessary.


Super Jib

custom engineered super jib crane
This jib crane, nicknamed “Super Jib”, is a full cantilevered model with a 60-foot span and a capacity of 7 1/2 tons. The jib is mounted onto an existing outdoor gantry crane at a nuclear power plant in California. The Super Jib required seismic calculations, special surface preparation with epoxy paint, and powered rotation. To the satisfaction of our customer, Bushman Equipment, Inc. designed and built this impressive piece in eight weeks.

Aluminum Cast House

This 12 metric ton, 24 ft reach jib crane lifts a distribution trough in an aluminum mill cast house. These pictures show the partially assembled jib performing a factory load test.

Bushman worked with the world's leading manufacturer of aluminum chill casting machines on this project.

Radiation Detection

This free standing jib crane was made to support radiation detection equipment for a southern U.S. steel mill. Inbound trucks hauling scrap steel are scanned for radioactive material before being allowed entry to the scrap yard where steel is recycled.

Shore Power Applications

Bushman has partnered for years with Cochran Marine, LLC, a leading provider and operator of electric shore power systems for passenger cruise ship ports and cruise lines. These specially designed "cable positioning devices" lift, payout and retract the heavy cables and plugs used to connect the ship to "clean" shore power while docked in a port-of-call.

US custinfo@bushman.com

  • Can we mount our jib differently?
    • The only foundation mounting Bushman recommends is the one shown on the approval drawing supplied with the crane. A qualified person must determine the adequacy of any other method of mounting.
  • How critical is leveling and how accurate does plumb have to be with floor mounted jib cranes?
    • The vertical column of a floor mounted crane should be plumb. These cranes rotate very easily. With a load on the boom, if the column is not plumb, the boom may rotate by itself. In order to prevent unwanted boom rotation, it is beneficial to spend extra time ensuring the column of a floor mounted jib crane is plumb.
  • How often is concrete poured accurately enough to merit not using a mortar bed? Alternatively, should it be standard practice to use a mortar bed?
    • Most installers will finish the concrete very flat and then bolt the jib crane column directly to the foundation. Our jib columns generally are very square because they are welded on a rotating semi-robotic jig. However, no weldment is perfect. The use of a mortar bed to correct any imperfections in the finish of the foundation or to plumb the jib crane column is perfectly acceptable.
  • What additional items do I need to mount the jib?
    • Floor mounted jibs require a concrete foundation with reinforcing steel rods and anchor bolts embedded in the concrete.
    • The wall-mounted jibs require high strength mounting bolts. These bolts must be no less than Grade 5 quality. The size is specified on the approval drawing and ranges from ½ to ¾ inch diameter. Usually a minimum of a man-lift and a forklift truck are required to install the cranes. Large cranes may need additional equipment for installation.
  • Where is a wall jib mounted?
    • Wall mounted jibs must be mounted to a structure determined to be adequate by a qualified person. The thrust and pull forces given for each jib, the weight of the jib, the capacity, impact, and hoist weight are some of the factors that must be taken into consideration.
  • What are the bolt/nut torque requirements for mounting?
    • 1" Mild steel anchor bolts/nuts or GR2 - 200 ft-lbs. max
    • 3/4" Mild Steel anchor bolts/nuts or GR2 - 150 ft-lbs. max
    • 3/8" Grade 5 bolts/nuts - 20 ft-lbs.
    • 1/2" Grade 5 bolts/nuts - 50 ft-lbs.
    • 5/8" Grade 5 bolts/nuts - 100 ft-lbs.
    • 3/4" Grade 5 bolts/nuts - 175 ft-lbs.
    • 1" Grade 5 bolts/nuts - 200 ft-lbs.
  • How are the jibs shipped?
    • Most jibs are shipped by a common carrier. They are usually shipped loose in a closed trailer with the hardware in a separate box. Some of the larger cranes require a flat-bed truck or trailer. Other methods are available. For an additional fee, units may be palletized to protect the finish.
  • Can I get the jib with motorized rotation?
    • Yes. Both wall mounted and floor mounted jib cranes can be fitted for motorized rotation.
  • What sort of electricity can I use to motorize my crane?
    • The typical voltage for large motors used in lifting devices is three phase and usually 230 or 460 volts. (230-3-60 or 460-3-60).
  • Is the jib available in different colors or finishes?
    • Yes. Please contact us for details and pricing.
  • Can I use a jib outdoors?
    • Our standard jib cranes are designed for indoor use. We can provide special shielding on the jib for outdoor use. Special maintenance will be required for jibs used outdoors. Please contact us for details and pricing.
  • What government or industry standards apply to these jibs?
    • Where Applicable:
    • Occupational Safety and Health Administration, General Industry standards
    • American Institute of Steel Construction
    • American Society of Mechanical Engineers/American National Standard ANSI B30
    • National Electric Code ANSI/NFPA 70
    • American Welding Society AWS-D14.1 & D1.1
  • What is the life expectancy of Bushman® jib cranes?
    • A jib's life expectancy depends on the environment, the severity and frequency of use, the ambient temperature, and other factors. For this reason, we cannot provide a value for life expectancy. Bushman® jib cranes are designed for daily use, and with the exception of routine maintenance, should provide years of trouble free operation.
  • Does the capacity include the hoist weight?
    • The rated capacity of the jib is the maximum "live load" the jib can pick up. A typical hoist and trolley weight is assumed and added to the rated capacity for design purposes. These assumed weights are 15% of the rated capacity and are not considered part of the "live load". However, hoist and trolley weights greater than 15% of the rated capacity should be considered part of the "live load".
