f. Assembly of Control Cords. On pull cord models, control
cords must be attached to control lever as follows: Facing air
inlet end of hoist, the cord to top handle (arrow pointing up)
should be attached to right end of lever; cord to bottom handle
(arrow pointing down) attached to left end of lever.
g. Assembly of Pendant Throttle Control. On pendant throttle
control models, control hoses must be attached to cylinders
on throttle valve housing as follows: Facing air inlet end of
hoist, the hose to “DOWN” lever side of pendant handle should
be connected to cylinder on right-hand side of housing; hose
to “UP” lever side should be connected to cylinder on left-
hand side of housing. The third hose connects to tapped hole
in bottom left side of control head and at top rear of handle.
7-5. TESTING HOIST.
a. General. After completion of assembly and before placing
hoist in service, hoist should be tested to insure proper
operation. To test: Suspend hoist from an overhead supporting
member of sufficient strength to carry combined weight of hoist
and rated load; connect to air supply of correct pressure; and
perform the following checks and adjustments:
b. Check Control Operation. Pull down on pull cord handle
or depress lever on pendant control briefly to determine that
hook travels in the direction to correspond with control being
operated. If load hook travels in a direction opposite to control
being operated, the pull cords or control hoses are improperly
installed. With Pendant Control Hoists the control lever should
attain a full throw when each lever on the handle is fully
depressed. If full movement of control lever is not accomplished,
the set screw in the corresponding control cylinder should be
turned in. If full movement occurs before lever is fully
depressed, the set screw should be turned out. The screw
should not extend beyond end of cylinder.
c. Check Hoist Under Rated Load. Attach rated load to lower
hook and check hoist operation.
(1) Operate hoist to raise load. When control is released,
hoist should stop and hold load at that level.
(2) Operate hoist to lower load a short distance, then release
control. Hoist should stop and hold load at that level.
(3) Operate hoist to lower load and observe rate of speed at
which load descends. Adjust lowering and hoisting speeds to
the desired rate of speed as outlined in paragraph 2-4.
Do not lift more than rated load except for test
purposes. Overloading hoist can result in chain
breakage, hook deformation and other failures which
can cause serious injury and damage. A test at greater
than rated load should be a properly supervised official
test only, not an operator test. If any load sustaining
parts have been altered, replaced or repaired, hoist
should be load tested at 125% of rated load by a
designated, qualified person, with a written report
recording test load, as recommended in ANSI B30.16
Safety Standards.
WARNING
7-6. PENDANT THROTTLE CONTROL ASSEMBLY.
a. General. After long periods of use, the pendant throttle
control assembly will require some maintenance attention. To
service the control handle assembly, shut off air supply, bleed
air from hoist and control, and disconnect hoses and strain
cable at control handle. Disassemble and reassemble control
handle as outlined in paragraphs b. and c. below.
b. Disassembly.
(1) Remove four screws and lift control lever guard from
handle.
(2) Drive lever pin from handle housing and separate two
control levers from housing.
(3) Using a suitable spanner tool, unscrew bushings and
valves from handle housing. Remove air seal gaskets from
bushing seats in the handle assembly. Remove “0” ring seals
from ends of valves and pull valves and valve springs from
bushings. Remove “0” ring gaskets from bushings.
c. Reassembly.
(1) Clean all parts in cleaning solvent and carefully inspect
for wear or damage before reassembly.
(2) Install new air seal gaskets on bushing seats in the
handle housing.
(3) Install new “0” ring gaskets on valve bushings. Insert
springs and valves in bushings and install new “0” ring seals
on ends of valves. Valves and bushings can now be reinstalled
in handle housing using spanner tool. “0” rings should be
lubricated before reassembly.
(4) Position control levers on housing, align holes and install
lever pin.
(5) Place guard over levers and secure to housing with four
machine screws.
(6) Reinstall control handle assembly on hoist. Attach control
hoses to handle housing as outlined in paragraph 7-4.g.
SECTION VIII - PARTS LIST
8-1. INTRODUCTION. Parts illustrations and parts lists covering
BUDGIT Air Hoists bearing model number given on front cover
will be found on following pages. When ordering replacement
parts, include with order the exact Catalog Number and Model
Number from hoist nameplate.
8-2. PARTS LIST. The parts lists consist of four columns. The
first column, Ref. No., is the index number of the parts on the
exploded view illustrations. The second column, Part Number,
lists the number of the part for ordering purposes. The third
column names and gives a brief description to help identify
the part. The last column(s) list the total number of times the
item is used in the assembly of which it is a part.
Notice: Information herein is subject to change without
notice. Parts must be order from a recognized BUDGIT
Repair Station or from a BUDGIT Hoist Distributor.
