INSTALLATION
Prior to installing unit, carefully inspect it for possible shipping
damage.
• Owners and users are advised to examine specific, local or
other regulations, including American National Standards
Institute and/or OSHA Regulations which may apply to a
particular type of use of this product before installing or
putting the unit into use.
• A falling load can cause injury or death. Before installing,
read “SAFETY INFORMATION” on page 3.
Mounting
Make certain unit is properly installed. A little extra time and
effort in doing so can contribute a lot toward preventing accidents
and helping you get the best service possible.
Always make certain the existing structure, that the unit is
mounted to, is strong enough to support the weight of the unit plus
the weight of a maximum rated load plus a generous factor of at
least 300% of the combined weights. Always contact a registered
structural engineer.
Space Requirements
Take the necessary time to determine the best installation location
to optimize the system’s capability. Allow adequate space, clear of
system and attachments, for safe traffic flow of personnel and
materials to and from the area. Allow clearance for the height of
transported loads and necessary work space. For optimum system
life, install the system indoors, or under shelter to reduce exposure
to weather.
Visually define where to install the system by marking the boom
pivot point on the work space floor, and marking off the boom tip
radius. This mock-up allows you to walk off the proposed load
path and direction of travel.
Tool Requirements
Typical Installation
• Socket set 1/2 in. drive
• Ladders / man lifts
• Leveling tools
• Lifting device to lift column and boom
• Mallet / hammer
• Chalk line
• Tape measure
• Torque wrench (up to 108 ft-lbs (147 Nm))
• Steel shims
• Anchor bolts (3/4 in. dia. max.)
• Non-shrinking grout
• Ensure ladders or scaffolding used by installation personnel
are reliable and capable of supporting the combined weight of
the installer and equipment.
• DO NOT replace self-locking nuts with standard nuts and
lockwashers. DO NOT reuse self-locking nuts. All fasteners
for jib crane must be grade 5 or better.
• Do not overtighten fasteners or bolts. Overtightening may
weaken fasteners.
Refer to ‘Safety Information’ section on page 3 before installing
rail system.
Erecting Column
1.
Mark jib crane column location on mounting surface with
chalk.
2.
Install footings (if required) per registered structural
engineer’s instructions. If footings are not required, install
anchors per the engineer’s and manufacturer’s specifications.
Refer to “Anchoring the System” on page 10.
3.
Position column in place.
4.
Plumb and level the column using the appropriate method as
described in either the
Nut Leveling Method
or the
Shim
Leveling Method,
then tighten anchor bolts to
manufacturer’s torque specifications.
