Jib, Gantry, Bridge and Floor Cranes Custom Articulating Style Jib Crane Elevating Mast: the mast can raise or lower under hydraulic or pneumatic power to accurately position the load without the need for a separate hoist.
Articulating Arm: the jib boom is constructed of two or three mechanically joined sections each with its own capacity to swivel or rotate. Reach: the combined distance that the articulating arm's span can attain.
Capacity: the heaviest load being lifted or maneuvered. Due to the nature of articulating arms, low capacity (up to 1,000 lbs.) is easily accommodated, while higher capacities become more complicated. Please contact a representative or call direct to discuss your application. Important Terminology for Jib Cranes Boom Length: Freestanding jibs are measured from the column center to the end of the boom. Structural column or Wall mounted jibs are measured from end of the boom to the hinge mounting plate. Capacity: Up to 15 tons. Height under the boom (H.U.B.): The distance from floor to the bottom or underside of the boom. Axial Rotation: The amount of rotation that is required to reach and place the item(s) lifted in their desired location. Manual rotation and power control rotation are possible. Limit Switches: Limits the rotation on a power-controlled jib to any desired amount except 360° or 180°. Collector Ring: Allows 360° rotation without damage to any electrical wiring on the jib crane. Template: A layout of the base plate allowing the jib crane's concrete foundation to be poured and cured before the jib crane is delivered. Types of gantries offered by Motivation: Adjustable: The height and clear span (distance between braces) are adjustable. Both options are available or combined for maximum flexibility. NaviGantry®: An option that provides steering of powered gantry cranes eliminating any form of tracks. This feature allows the gantry crane to service many areas of the plant. The Navigantry® is an exclusive patented product of Motivation Industrial Equipment.
Track Mounted: Casters of the gantry are equipped to run either on inverted angle, 30 or 40 lb. rail or a system that tracks along a floor mounted angle rail.
Utility: High-beam design, beam bolted to support legs without bracing. Quick assembly service crane.
Capacity: up to 15 tons with higher capacities available upon request.
Aluminum Options: available upon request. Terminology Associated with Gantry Cranes: Span: The span is the overall length of main beam.
Height under the beam: The H.U.B. is the measurement from the floor to the underside of the main beam.
Overall Height: The overall height is the measurement from the floor to the top of the gantry hangers on the main beam.
Clear Span: The clear span is the unobstructed work area between the braces.
Brace Length: Attached midway down each leg bolted to the hangers.
Beam Flange Width: The width measurement of the beam flange.
A Frame Width: The "A" frame width is the overall measurement of the "A" frame at the base.
Hangers: Four (4) individual pieces welded to the top of the beam to which the legs and braces are bolted.
Clear Lift: The maximum vertical travel a load can be lifted. A number of factors determine the range of vertical travel. The headroom of the hoist / trolley, depth of lifting beam or special rigging The overall height of these products must be deducted from the available height under the beam, the net difference is the clear lift available.
Full Beam Trolley Travel: By extending the hangers of the gantry to fit the width of the hoist/trolley, the legs and braces of the gantry are now positioned far enough away from the main beam to allow the hoist/trolley to travel under them. Now the hoist/trolley are not limited by the clear span and run the full length of the beam.
Directional Locks: 4-position locks (4PL) allow the user to lock the direction of the wheel in a north, south, east or west position. For power driven units, only 2 (4PL) or 1 set, would be required if necessary.
Port-A-Cart System: With minor changes, Motivation Industrial Equipment can take the spreaders and casters of our gantry crane and transforms them into a transport cart.
Jack Kit: Used on adjustable height gantries only, 2 are required for most gantry and 4 (1 for each leg) are required for high capacity gantries. A screw jack allows height adjustment without the use of an overhead device or forklift. www.motivational-industrial.com |
