Ace Tips on Jib Cranes
There are various types of jib cranes but the great majority of them fall into one of three categories:
1) free standing jib cranes
2) wall bracket jib cranes
3) wall cantilever jib cranes
Ace Industries manufactures and distributes a full line of industrial jib cranes as shown above. We also supply fittings for those
interested in making their own wall bracket and wall cantilever jibs. We have jibs and components by CM, LiftTech, Yale, Gorbel,
Spanco and others. Like our other products, there are no compromises. Heavy duty bearings provide smooth operation and
long life. Optional bottom or top entry collectors provide trouble free electrification for 360 degree rotation. Motorized models
are available. Standard capacities to 5 ton. Spans to 20 feet with 20 feet under the boom.
We find that the foundation requirements for free standing jib cranes are often underestimated. Standard footing requirements
are shown on the free standing jib dimension page.
The proper installation of a jib crane can easily exceed the cost of the equipment. A poor installation on the correct foundation
or structure can cause problems. Difficulty in movement and undesired rotation after release can be dangerous to plant
personnel. Have our expert technicians install your jibs to insure a satisfactory result.
Wall traveling jib cranes and other special applications are also available. Hoists and trolleys of every type and capacity are
available from our stock to complete your jib crane project. This assures you of one source responsibility.

Wall Bracket Jib Cranes
A wall bracket jib crane is one of the most popular jib crane types, and is usually the least
expensive of the jib crane alternatives. Application requirements for a wall bracket jib are that (1)
there is a structurally sound wall or column to mount it on, and (2) there is sufficient clearance
above the boom to accommodate the support rod that must be used.
Wall bracket jib cranes have the following standard features:
200 degrees maximum rotation
Bronze bushings and oil impregnated bronze thrust washers to provide easy rotation and
superior load positioning.
Formed bracket fittings with no welds in tension and all bolts in double shear provide safety.
Engineered for use with powered hoists. A factor of 15% of the jib crane capacity is allowed for
the hoist and trolley weight with an additional 25% of the capacity allowed for impact.
Single tie rod with right hand thread at both ends for easy adjustment and installation.
All connections bolted
Grease fittings for field lubrication
Powered rotation optional
Wall bracket kits are for those who want to make their own wall bracket jib cranes.
Buy your own I-beam locally, use these high quality brackets, and do your own assembly. The wall
bracket kits consist of the top wall bracket, the bottom wall bracket, and the beam bracket. The
two wall brackets have bronze thrust washers, bronze bushings, and grease fittings. The top wall
bracket and the beam bracket include a tie rod clevis. Tie rod and other hardware is not included
with the kit but may be ordered separately.
Caution: Dimensions between brackets must be held to those shown in the charts and drawings. We cannot be responsible for
incorrect installation or, any deviation from drawings and charts relating to capacity, span, or other matters.

Wall Cantilever Jib Cranes
A wall cantilever jib crane is one of the most popular jib crane types,
and is used when headroom is important requiring the jib boom to be
located at the highest point possible to provide maximum lift for the
installed hoist. Application requirements for a wall cantilever jib are
that (1) there is a structurally sound wall or column to mount it on,
and (2) there is sufficient clearance above the boom throughout its
rotation arc.

Mast Type Jib Cranes
The mast type jib crane is floor supported, top stabilized, and is capable of 360 degree
rotation via a top and bottom bearing assembly. The following three requirements must be
met before considering a mast type jib crane:
An adequate structural support to support the crane at the top of the mast must exist. If the
jib is installed underneath an overhead crane runway or building truss, then the deflection of
the supporting member may not exceed 1/2 inch.
Clearance overhead for the pivot assembly must exist. Clearance overhead for the boom to
rotate must exist.
Two available styles:
MT400 Full Cantilever - provides for a maximum amount of lift where full use of available
headroom is desired.
MT450 Full Cantilever - jib boom can be placed at a specific height to clear overhead
obstructions.
Standard features, mast type jib cranes:
360 degrees rotation
Bronze bushings and oil impregnated bronze thrust washers to provide easy rotation and superior load positioning.
Mast/beam connections eliminate the need for tie rods or knee braces found on competitive designs, thus permitting maximum
trolley travel.
Engineered for use with powered hoists. A factor of 15% of the jib crane capacity is allowed for the hoist and trolley weight with an
additional 25% of the capacity allowed for impact.
All connections bolted
Grease fittings for field lubrication
Powered rotation optional
