Air And Lube Requirements - Ingersoll-Rand 7700-E Series Installation, Operation And Maintenance Instructions

Air and Lube Requirements

Air Pressure of 90 psig (6 bar) at the air inlet of the hoist is required for maximum motor efficiency. If necessary, an
air regulator should be installed to maintain this pressure when hoist is in operation.
Filtered And Oiled Air will allow the hoist to operate more efficiently and yield a longer life to operating parts and
mechanisms. A line filter capable of filtering particles larger than 50 microns should be used with a line oiler.
Filter-Regulator-Lubricator (F-R-L) assembly model C38341-810 is recommended for use with each hoist. The
capacity of this F-R-L is adequate to provide clean (40 micron) oiled and regulated air for the hoist. The F-R-L must
be installed on the stationary air line, in that order, with the lubricator nearest to the hoist.
Load Chain Lubrication - Chain should be lubricated periodically with heavy "EP" Gear Oil. Occasional cleaning of
the chain under normal operation conditions will tend to reduce wear and prolong chain and pocket wheel (or
sprocket) life. To properly clean, remove chain from hoist (refer to
and wash in an oil solvent. Lubricate chain. Under highly contaminated operating conditions, the load chain should
be cleaned and re-lubricated with greater frequency to remove grit, sand, and other contaminants.
Oil Reservoir in head should be filled with spindle oil (29665) after each 40 hours of operation.
Inject Grease (33153), 2 to 3 strokes, through grease fitting in hoist housing to provide lubrication for gearing, and
through fittings of trolley wheels a minimum of every 160 hours of operation.
Lower Block Assembly should be lubricated any time the lower block is disassembled either for inspection or for
maintenance, or for chain replacement. Refer to
lubrication instructions.
Recommended Hose Size - 1/2 inch (13 mm) nominal inside diameter.
Recommended Lubricants: Spindle Oil 29665, 1 qt. (0.9 liter) container for oiler and air inlet; Grease 33153, 5 lb. (2.3
kg) can for gears, lower block and bearings; O–Ring Lubricant 47622327001, 2 oz. (28g) tube for lubrication and
installation of O–Rings.
