SECTION II - INSTALLATION
2-1. GENERAL. BUDGIT Air Hoists are completely lubricated
and load tested before being shipped from the factory. To place
hoist in service, attach to a suitable overhead suspension
(Paragraph 2-2) in area to be used; connect hoist to nearest
air supply (paragraph 2-3); and check and adjust hoist speed
(paragraph 2-4).
2-2. SUSPENDING HOIST.
a. On hook suspended hoists, select a suitable overhead
support in area hoist is to be used (one capable of holding
combined weight of hoist and its rated load) and hang hoist
up. Be certain that upper hook is firmly :seated in center of
hook saddle and that the spring safety latch is properly
closed over hook opening. In some cases, it may be
necessary to first remove spring latch before hook will fit over
a support. Reinstall latch after hook is engaged.
b. On lug suspended hoists, select a suitable overhead support
in area hoist is to be used (one capable of holding combined
weight of hoist and its rated load). Mount hoist using through
bolts of appropriate size to fit mounting holes in suspension
lug at top of hoist. Use only suspension bolts provided by
Yale
Lift-Tech. (See table below.)
The structure used to suspend hoist must be of sufficient
strength to withstand reasonable forces to which hoist and
support may be subjected. Hoist must be aligned with
load to avoid side pulls.
CAUTION
If trolley is mounted on an open-end beam, end stops
must be installed to prevent trolley from running off
the end of the beam resulting in injury to operator and
other and damages to load and other property.
WARNING
c. On rigid mount trolley suspended hoists, the trolley side
plates must be properly spaced so trolley will fit (beam on
which hoist will operate. Adjustment for various I-beam sizes
is accomplished by rearrangement of spacer washers on
through bolts which connect trolley side plates to hoist
suspension lug. Refer to instruction sheet furnished with
BUDGIT Rigid Mount Trolleys for complete instructions.
d. If chain container is to be used on hoist, install it following
instructions furnished with container.
2-3. CONNECTING HOIST TO AIR SERVICE.
a. Connect hoist to nearest filtered and lubricated air source
using minimum 1/2" I.D. air hose assembly (see Figure 2-1).
Avoid use of reducing bushing and nipple or hose assemblies
of smaller diameters which may cause restrictions.

c. A filter and lubricator unit (Figure 2-3) must be installed
between air source and air hose leading to hoist. These keep
air flowing to hoist free of dirt and add lubricant to air so
internal parts of motor are constantly lubricated. Use Air Hoist
Motor Oil or good grade IOW machine oil (approximately
viscosity 150 SSU at 100°F.) Multi-viscosity, detergent type
engine oil is not recommended. Feed one drop of oil for every
50 to 75 cubic feet of air going through the air motor.

b. If hoist is suspended by trolley, provide sufficient hose to
reach from air source to farthest point of trolley travel. BUDGIT
Hose Trolleys are recommended to keep hose up out of the
way (see Figure 2-2).
