Technical Information and Specifications
Product Code for Tie Rod Jib
(Tie Rod Jib includes 752 fitting kit, boom, stem, boom/tie rod connection hardware, end
stops, and end stop hardware. Mounting hardware is supplied by others.)
Product Code for Tie Rod Jib Fitting Kit
(Fitting Kit includes fittings only. This kit is for customers providing boom, tie rods, con-
nection hardware, mounting hardware, etc.)

Crane Terms
Anchor Bolts: Large steel bolts used to mount a base mounted pillar jib crane to the H.S.I. recommended foun-
dation.
Boom: The horizontal beam on which the hoist trolley travels.
Fitting Centers: The distance, centerline to centerline, between two support brackets (fittings) of a wall mounted
jib crane.
Capacity: The maximum live weight that the crane is designed to support.
End Stops: Bolted to each end of the boom to prevent the trolley from falling off of the beam.
Foundation: For free standing pillar base mounted jibs. Foundations are used to support the jib and prevent it
from tipping over.
Gussets: Reinforcing plates used to stiffen mast at the base plate.
Head: Houses the roller, and lowers the crushing forces that are imposed on the mast.
Height Under the Boom (H.U.B.): The distance from the finished floor to the underside of the crane boom. To
find the under- boom, take the height of the load, plus the distance the load is lifted, plus the headroom require-
ments of the hoist/trolley and any attachments. Extra room aside from mandatory room needed could be helpful.
Mast: The vertical member of the jib, which supports the crane. Pillar jibs have round pipes as masts.
Overall Height: The highest point of the jib crane (including any hardware). A minimum clearance (usually 3”) is
required from any overhead obstruction.
Hoist: The actual lifting mechanism (powered by electric, air, or manual movement) that hangs from the trolley
that rides on the boom of a jib crane.
Trolley: The mechanism that travels back and forth on the crane boom (powered by electric, air, or manual
movement) which the hoist hangs from.
Overturning Moment: The overturning moment is the force applied to the mounting structure of a sefl-support-
ing pillar jib. This load is created by suspending a load from the boom, and is greatest at full load, at the very end
of the boom.
Rotation Stops: Limits the rotation of a pillar base mounted jib crane boom (which are standard at 360°). Stops
are field welded to the mast.
Span: The span for a pillar base mounted jib crane is the distance from the center of the mast to the end of the
boom. The span for a column mounted crane is measured from the face of the mounting surface to the end of the
boom. The span for a mast type jib crane is measured from the center of the vertical mast to the end of the
boom.
Thrust and Pull: Thrust and Pull are forces applied to a wall/column mounted jib cranes support structure. Thrust
is the pushing force exerted on the structure, and pull is the tensile, or pulling force. Thrust and Pull are equal to
each other (but opposite in direction), and are given for maximum at full load at the end of the boom.
Clear Span: The measurement between the end stops on a crane boom.
Hook Travel: The distance that the hook on the hoist travels.
In order to better understand jib cranes, here are the commonly used terms that are used to specify and design jibs.

Pre-Installation
1. WARNING There must be an adequate wall, column, or truss to support the jib crane. Consult
a qualified structural engineer to determine if the support structure is adequate to support the
thrust and pull of your crane (See Crane Drawing for Thrust and Pull)
2. Ensure there will be sufficient clearance (3” minimum) above the boom throughout the rotation.
3. Check jib crane for physical damage due to shipping.
4. Ensure all capacity stickers and warning labels are clearly visible and properly affixed.
5. Check packing list to ensure no parts have been lost prior to initiating assembly of crane.
6. See Jib Crane Drawing for bolt locations and dimensions.
7. Read entire manual before installing the crane.
Installation
1. WARNING If multiple cranes were ordered, locate stamped serial number on each crane part
for proper part matching during installation. Although crane parts may appear to be identical,
each crane is assembled and built separately. All parts that do not have the same stamped
serial number may not line up properly for installation.
2. Reference Jib Crane Drawing included in the crane information packet.
3. Make sure the support structure (COLUMN) is plumb for installation. Prepare the COLUMN for
jib fittings.
4. Use the Crane Drawing as a guide to determine the bracket hole layout for the TOP FITTING
bracket and BOTTOM FITTING bracket. Make sure the bracket holes are properly
aligned.
5. Drill bolt holes for the TOP FITTING bracket and BOTTOM FITTING bracket, and bolt
them to supporting structure (COLUMN). Do not torque bolts until brackets are plumb.
See Figure 1. Note: Hardware to bolt fittings to COLUMN is supplied by others.
6. Plumb TOP FITTING and BOTTOM FITTING through pivot holes. If necessary, shim between
COLUMN and fittings (shims by others).

Lubrication
1. The most economical way to maintain a jib crane and keep it in good operating condition is to
lubricate all moving parts regularly.
2. Regular inspection of all parts should be made and all loose parts should be adjusted. Parts
that become worn should be replaced immediately.
3. The lubrication interval varies with the use of the machine. A crane operating 24 hours a day, 7
days a week, should demand lubrication once a week. Whereas a standard duty crane, operat-
ing eight hours a day on a five day week should be lubricated once every two to three weeks.
Cranes under a standby classification, being used once or twice a month, should be lubricated
at least once every six months.
4. The actual interval from one lubrication to the next depends entirely upon the type and length
of operation to which the crane is subjected. These factors are variable and sometimes cannot
be definitely determined. In this case, the crane operator or maintenance engineer would de-
termine when the crane should be lubricated.
5. The roller bearings on the jib crane require lubrication. They are serviced by pressure type fit-
tings.
6. The recommended lubricants for these bearings are:
a. Texaco Marfax No. 0 for below 32 degrees F
b. Texaco Marfax No. 1 for above 32 degrees F
7. If Texaco products are not available, equivalent lubricants are satisfactory.
