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

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

Gorbel Jib Crane Features
- Precision tapered roller bearings in top pivot and trunnion assemblies provide smooth operation and long life.
- Full supporting triangular base plate gussets are used (in lieu of struts) to minimize crane deflection, thus making it easier to accurately position loads.
- Independent head assembly, installed separately from the boom for easier installation.
- Recessed bearing assembly allows greatly reduced clearances needed for installation.
- Bolted head/boom connection which permits separate installation and provides maximum lift for the hoist, since it can be installed very close to the underside of the lower ceiling obstruction for greater headroom.
- In-head totally enclosed, bottom entry collector assembly allows the option of easily adding power to the hoist for 360 degree rotation at the time of or after purchase.
- Optional power rotation
- Optional J-Bolt anchors
- Optional festoon electrification
- Optional anchor bolt template (paper or wood)
Gorbel Jib Crane Applications

Gorbel 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.
- Manual Rotation Stops - Rotation stops are required to limit the WSJ360 rotation to less than 360 degrees to prevent boom damage to machines, equipment, or building structure.

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
allowance
(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 =
(distance
between
trolley
stops) -
(hoist
trolley
length)
