Dearborn Overhead Crane features Gorbel Jib Cranes.
Structural Beam Jib Cranes
Free Standing Jib Cranes
They are perfect underneath large bridge cranes, in open areas where they can serve several work stations, in outdoor applications such as loading docks, or in machining and assembly operations where they can be overlapped with other jib cranes to provide staged coverage.
- Available in floor mounted, insert mounted and sleeve insert mounted styles.
- Capacities from 500 to 10,000 lbs, with spans to 20'.
- Use I-beam boom assemblies for heavier
Wall Cantilever Jib Cranes
Provide hoist coverage and 200 degree rotation for individual use in bays, along walls, or columns of plants, or as a supplement to an overhead crane or monorail system. This jib has the advantage of providing maximum lift for the hoist, since it can be installed very close to the underside of the lowest ceiling obstruction. It is composed of a vertical mast mounted to 2 brackets on a wall or vertical building beam with a boom that cantilevers out, perpendicular from the wall at the top.
- Capacities from 1/4 ton to 5 tons
- Spans to 20'
- Requires very little head room and exerts less force on the structure it is mounted to
- Requires a structurally adequate wall or column to support the jib, and needs sufficient clearance above the boom
Wall Bracket Jib Cranes
The most economical means of providing hoist coverage for individual use in bays, along walls or columns of plants, or as a supplement to an overhead crane or monorail system. This jib has 2 brackets that mount to a wall or building beam. The bottom bracket has a boom that is perpendicular to the wall with a bracket toward the end that a tie rod is attached to. This is the least expensive jib, but it takes up the most head room and it exerts the most force on whatever it's mounted to.
- Capacities from 1/2 ton to 5 ton
- Spans to 30'
- 200 degree rotation on primary boom
- Suited for applications where maneuvering around obstacles or swinging under obstructions is necessary
- Available as complete units or money saving kits and you supply the beam
Mast Type Jib Cranes
Floor supported, top stabilized, and capable of 360 degree rotation via a top and bottom bearing assembly. MT Series Cranes are available in two styles.
- Full Cantilever - Provides maximum amount of lift where full use of available headroom is desired.
- Drop Cantilever - Jib boom can be placed at a specific height to clear overhead obstructions.
Workstation Jib Cranes
Free Standing Work Station Jib Cranes
The ideal substitute for traditional, heavy I-Beam Jib Cranes. These jibs are designed to service circular areas and support tool balancers, air balancers, vacuum lifters, and hoists. When floor mounted, they can accommodate up to a 360 degree rotation. Capacities are available from 100 lbs. to 1000 lbs. with spans up to 16'.
- Most can be bolted directly to existing floors without adding special foundations
- Features a retaining pin through the pivot pin to help resist accidental upward dislodgement of the boom assembly
- Includes hoist trolley
Wall Cantilever Work Station Jib Cranes
The ideal substitute for traditional, heavy I-Beam Jib Cranes. These jibs are designed to service circular areas and support tool balancers, air balancers, vacuum lifters, and hoists. When column or wall mounted, they can handle up to a 200 degree rotation. Capacities are available from 100 lbs. to 1000 lbs. with spans up to 16'.
- Available in steel (all capacities) or stainless steel (capacities to 500 lbs.)
- Uses enclosed track for the boom assembly, which reduces dead weight for easier rotation than traditional I-Beam Jib Cranes
- Uses tapered roller bearings at the pivot points for unsurpassed ease of rotation.
Aluminum Tie Rod Work Station Jib Cranes
Light-weight, high strength extruded aluminum enclosed track. This revolutionary track reduces the rotational dead weight of the boom by 56% to 68%, making the jib up to 40% easier to rotate than comparable I-Beam Jib Cranes. The tie rod design minimizes deflection and is more precise when positioning loads than other jib cranes.
- Can be mounted to wall or column
- Available in capacities from 150 - 2000 lbs. with spans up to 20'
- Has less deflection for easier load control and positioning
Gorbel Articulating Jib Cranes
Gorbel Free Standing Articulating Jib Cranes
Perfect for applications that demand an Articulating Jib, but lack the walls or columns needed to mount the crane. These cranes offer effortless rotation and a consistent responsiveness when positioning loads in a work cell, through open doorways, or into machines.
- Floor mounted for easy installation and relocation
- Capacities from 150 to 2000 lbs. with spans to 16'
- 360 degree rotation at both pivot points (optional)
- Can be used with hook mounted lifting devices (electric, air or vacuum)
Gorbel Ceiling Mounted Articulating Jib Cranes
You can move loads around corners, reach into machines or doorways, and swing under obstructions. This versatile crane is perfect in applications that require an operator to rotate the jib in close to the pivot point.
- Capacities from 150 to2000 lbs. with spans to 16'
- Can be mounted to a platform supported from a Gorbel Work Station Bridge Crane to allow the jib to swing under an obstruction or outside the normal coverage of a bridge crane
- Can be used with hook mounted lifting devices (electric, air, and vacuum)
Gorbel Wall/Column Mounted Articulating Jib Cranes
Move loads around corners, reach into machines or doorways, and swing under obstructions. This crane is perfect in applications that require an operator to rotate the jib in close to the pivot point.
- Capacities from 150 to 2000 lbs. with spans to 16'
- 200 degree rotation on primary boom
- Suited for applications where maneuvering around obstacles or swinging under obstructions is necessary
Special Jib Cranes/Accessories
Foundationless Jib Cranes
A poured foundation can cost as much or more than the jib crane itself and take a week to cure. It's easy to relocate a jib where there's no poured foundation. That means flexibility in choosing initial jib location. You can place it closer to machines or other obstructions, because there is no need for a large square foot area for a concrete pour.
- Capacities: 250/500/1000 lbs.
- Height: HUB 8' to 14'
- Spans: 4/6/8/10/12/14/16 feet
Motorization Retro-fit Drive Kit
When load weight or operation frequency make manual rotation non-economical, impractical or unsafe on an existing manual rotation jib crane, you need Gorbel's Retrofit Drive. No matter who makes your jib crane, you can motorize it easily.
Turnkey assembly including:
- Motor
- Reducer
- Controls

Jib Crane Accessories
Available Accessories:
- Festoon Clamps - Festoon clamps anchor the festooning
at the start of the jib boom. They also prevent the festoon gliders from
exiting the track and they can provide redundant stop for the trolley.
Festoon clamps for vacuum hose are also available.
- Festoon Gliders - Festoon gliders are used to support
flat electrical cable along the jib boom. No tools are required to attach
the festooning to the gliders. One festoon clamp is required with the
use of festoon gliders.
- Festoon Trolleys - Gorbel festoon trolleys are used
to support flat cable, air hose, or round cable along the jib boom. The
trolleys have four wheels and a pivoting festoon saddle support. Festoon
trolleys for vacuum hose are also available. One festoon clamp is required
with the use of festoon trolleys.
- Flat Cable and/or Air Hose - A Flat cable festooning
system is required when using an electric powered lifting device. Air
hose is also available and is supported by festoon trolleys.
- Four Ring Electrical Collector (Top or Bottom Entry) -
A collector is needed to provide a continuous 360 degree boom rotation
when using an electrical powered lifting device. A bottom entry collector
requires 4 additional inches of clearance above the pivot pin. A top
entry collector requires 11 - 1/4 additional inches of clearance above
the pivot pin.
- Air Swivel (Top or Bottom Entry) - An air swivel is
needed to provide a continuous 360 degree boom rotation when using an
air powered lifting device. A bottom entry air swivel requires an additional
5 inches of clearance above the pivot pin. A top entry air swivel requires
between 8 - 1/2 and 9 1/2 inches (depending on span and capacity) of
additional clearance above the pivot pin.

Jib Crane Terminology
Anchor Bolt Load: The total amount of force that is applied to each supporting
anchor bolt; usually measured in kips.
Axial Load: The total vertical force applied to the supporting structure.
Formula: Axial load = (overall weight of the crane) + (design factor x
weight of load)
Boom: The horizontal beam (track) upon which the hoist trolley travels.
The "jib" of the jib crane.
Bracket Center: The distance, center line to center line, between two
supporting brackets of a wall mounted jib crane (i.e. the distance between
the two wall mounting points).
Capacity: The maximum live weight that the crane is designed to support.
For jib cranes, the design load is based on the capacity, plus a hoist
and trolley allowance (15% of capacity) and an impact al lowance (25% of
capacity). The allowable deflection of the crane is calculated using the
design load plus the hoist allowance. Load testing can be performed to
125% of rated load capacity. Standard Gorbel® jib cranes are available
in capacities up to 5 tons (4536 kg).
Deflection: The difference in elevation at the tip of the boom between
an unloaded crane and a fully loaded crane; usually measured in inches.
Gorbel tends to have stricter deflection criteria than others in the industry.
Typical deflection of Gorbel® designs (where L = span of the crane in inches):
WC200, FS300, FS350, FS350S, MT400: L/150 WB100: L/450
Foundation: Free Standing jib cranes require that a special foundation,
usually of concrete and steel, be used to support the crane and prevent
the crane from tipping over. Foundation recommendations can be found in
the price pages and in the installation manual.
Height Under Boom (HUB): The distance from the floor to the underside
of the crane's boom. The minimum height under boom equals the height
of the load, plus the maximum distance the load is to be lifted, plus the
headroom required for the hoist, trolley, and attachments.
Mast: The vertical steel component of the jib crane which supports the
crane. Free Standing Jib Cranes (including Work Station Jibs) have a circular
pipe for a mast, Wall Cantilever Cranes have standard I-Beams, and Mast
Type Cranes have wide flange beams. Wall Bracket Cranes do not have a mast.
Overall Height: The distance to the highest point on the jib crane (should
include hardware). A minimal clearance (nominally 3 inches) is required
from any obstructions above the boom or tie rod assembly throughout the
entire rotation of the crane.
Span: For a jib crane, span is the distance from the center of the pivot
point to the end of the boom. Note that "span" is greater than
actual "working span" or "hook coverage."
Supporting Structure: For a Free Standing Jib Crane (FS300, FS350, FS350S)
the supporting structure is the foundation which the crane is bolted to
or implanted in. For a Wall Bracket or Wall Cantilever Jib Crane (WB100
or WC200), the supporting structure is the wall or column to which the
crane is bolted. Mast Type Jib Cranes have a supporting structure at both
the ceiling and the floor.
Thrust & Pull: Forces exerted by a crane on its supporting structure.
Thrust is the pushing (or compressive) force exerted on the structure,
while Pull is the tensile force. Thrust and Pull are thus equal (but opposite
in direction) to each other. The maximum thrust & pull occurs when
the crane is loaded at full capacity.
Working Span: The working span (or hook coverage) is less than the span
of the crane. It is a function of the maximum hook reach and the ability
to get the trolley close to the mast. Working span = (d istance between
trolley stops) - (hoist trolley length)
