Jib Cranes


Sleeve Mounted Jib

 

There are various jib crane models from which to choose: floor-mounted pillar types; top and bottom-supported units; wall or column-mounted versions; and models that afford manual or motorized rotation. Built to the highest industry standards.


CUSTOM JIB CRANES 


Floor plate Jib Cranes


The floor plate mounted jib crane is widely used to control or position a load in areas that are generally inaccessible to other material handling equipment. They are designed to provide reliable, long-life performance with minimal maintenance. This free standing jib crane provides 360-degree rotation. Available options include taglines, festoon systems, collector ring assemblies and motorized rotation.


Wall Mounted Jib Cranes


Economical wall mounted full cantilever jib cranes are designed for mounting on to walls or columns to serve a 180-degree arc. They are useful under an overhead bridge crane when there is adequate head room.


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 headroom 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.


Capacities are based on the live load at the hoist hook, making allowances for hoist and trolley weights, and impact.


Applications


Motorized rotating jib cranes are widely used to control or position the load in an area that is generally inaccessible to material handling equipment, or where the load, weight or duty cycle make it impractical to employ manual rotation.


Jib Crane with 360° Rotation


Jib cranes are available either with a base plate for floor mounting or without a base for mounting the pillar directly into a concrete foundation. 


In addition to the standard jib crane construction features, these motorized units include motor, variable speed electronic drive, heavy-duty chain drive, pintle pin and reducer. Optional equipment includes current collector rings for 360° continuous electrification, and tagline assembly for festooned hoist conductor cables. Control push buttons are usually incorporated into the hoist push button station to facilitate operator control (push button optional).

The motorized drive rotation of the jib boom typically provides a rotation speed of 1/2 RPM, but speeds up to 1 RPM are available.


Top and Bottom Mounted Jib Crane


These jib crane models provide 360° of rotation and are used where support can be provided for the top bearing assembly by securing to a ceiling, truss, wall, beam or column. The bottom bearing assembly is secured to the floor or to a foundation.


The mast and boom are made of heavy structural beams, fabricated in sections for easy shipping and handling. The bottom bearing is a self-aligning tapered roller bearing in a machined housing and is provided with a pressure lubrication fitting. The top bearing is a sealed ball bearing with provision to allow for expansion and contraction of the structure to which it is attached.


The jib boom is a standard I-beam. All parts are factory tested to assure proper fit and alignment.  The overall height of the mast assembly can be varied to suit existing conditions and will proportionately change the height under the boom.


Full Cantilever Jib Cranes


The full cantilever style is used where the available headroom dictates that the jib boom be as high as possible to provide adequate clearance under the boom. Note that the compression brace limits hoist travel. Special V-bracing can be provided to accommodate full hoist travel.


The sleeve mounted jib has a steel pillar that inserts into a matching sleeve. 


Options


Bottom Entry Collector Ring Assembly


Optional bottom entry electrical collector assembly includes junction box, internal wiring, collector assembly in web of beam, and junction box in head assembly for power connection to electrical hoist.


Air Swivel

This feature provides the capability of 360° rotation when using an air hoist on the boom. Included is a pipe nipple 12" above the floor for attaching the air supply hose, a pipe running inside the pillar connecting to the swivel fitting, and a connector to which the air hose for the hoist can be attached. Top entry systems are also available.


Top Entry Collector Assembly

Top entry electrical collector assembly may be used on all size cranes where electrical power source can be connected from the top of the jib. Internal wiring in the pillar is not necessary.


Hand Geared Rotation


Tagline Festoon System

An improved festoon system is offered which includes a messenger wire, swivel eye pulleys, and cable connections, with capabilities for attaching round cable.


CUSTOM DESIGNED JIB CRANES


Standard Jib Cranes


Introduction to Floor Mounted Jib Cranes


Heavy duty floor mounted jib cranes are designed and constructed for industrial use with years of trouble-free service.


The jib crane boom is fabricated out of a steel I-beam or a wide flange beam and has removable end stops. A machined lower roller carriage is housed in the jib crane head section that features heavy steel side plates. The lower roller carriage is mounted on adjustable tension bolts to allow for field adjustments. The support column for the jib crane is constructed out of steel pipe with a heavy base plate and reinforcing gussets.


Introduction to Wall Mounted Jib Cranes


Wall Mounted jib cranes are constructed from high grade steel components and are designed for trouble free use. The hinges are equipped with self-lubricating Teflon bearings and hardened pins.

Full Cantilevered Wall Mount


This style of wall mounted jib crane is ideal when maximum head room is needed for your lifting application. The boom has 180° of manual rotation. Please contact the factory for other options and accessories.

Overbraced Tie Rod Wall Mount


The overbraced tie rod wall mounted jib crane provides economical hook coverage with 180° manual rotation. The tie rod has threaded ends and will allow easy field adjustments. Assembly required at installation.


Introduction to Portable Jib Cranes

The fully portable jib crane eliminates any need for costly site preparation and footing expenses required for conventional floor mount jib cranes. The design of this jib allows easy transportation around the shop floor by fork truck. This means it can serve multiple uses and applications. It can be used in upper floors of your facility and then stored out of the way.

FAQ's


  • Can we mount our jib differently?
    • The only foundation mounting recommended 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 mounting bolts.  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.
  • Can I get a special jib?
    • Contact us with your specifications and we will let you know if we can meet them.
  • Can I get the jib with motorized rotation?
    • Both wall mounted and floor mounted jib cranes can be fitted for motorized rotation.
  • Is the jib available in different colors or finishes?
    • Yes.
  • 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 is the life expectancy of Bushman Equipment, Inc. 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. Jib cranes are designed for daily use, and with the exception of routine maintenance, should provide years of trouble free operation.
  • How fast can I get my jib?
    • Normally our standard jib cranes have a 3 to 4 week lead-time. Other time requirements apply to special or modified cranes and our large jib cranes. Please contact us for lead times on specific products
