LUBRICATION POINTS
A regular frequency of lubrication must be established for all
lubrication points. Normally, this is based on component
operating time. The most efficient method of keeping track of
lube requirements is to maintain a job log indicating crane
usage. The log must use the engine hourmeter to ensure
coverage of lube points that will receive attention based on
their readings. Other lubrication requirements must be made
on a time basis, i.e. weekly, monthly, etc.
All oil levels are to be checked with the crane parked on a
level surface in transport position, and while the oil is cold,
unless otherwise specified.
On plug type check points, the oil levels are to be at the
bottom edge of the check port.
On all hoists with a check plug in the drum, the fill plug shall
be directly on top of the hoist, and the check plug level.
All grease fittings are SAE STANDARD unless otherwise
indicated. Grease non-sealed fittings until grease is seen
extruding from the fitting. One ounce(28 grams) of EP-MPG
equals one pump on a standard one pound (0.45 kg) grease
gun.
Overlubrication on non-sealed fittings will not harm the
fittings or components, but underlubrication will definitely
lead to a shorter lifetime.
On sealed U-joints, care must be exercised to prevent
rupturing seals. Fill only until expansion of the seals first
becomes visible.
Unless otherwise indicated, items not equipped with grease
fittings, such as linkages, pins, levers, etc., should be
lubricated with oil once a week. Motor oil, applied sparingly,
will provide the necessary lubrication and help prevent the
formation of rust. An Anti-Seize compound may be used if
rust has not formed, otherwise the component must be
cleaned first.
Grease fittings that are worn and will not hold the grease
gun, or those that have a stuck check ball, must be replaced.
Where wear pads are used, cycle the components and
relubricate to ensure complete lubrication of the entire wear
area.
CraneLUBE
Manitowoc highly recommends the use of CraneLUBE

performance. Contact your Manitowoc Distributor for
information about the Manitowoc’s CraneLUBE lubrication
program.
Safety
To lubricate many of the locations the engine will need to be
started. After positioning areas of the unit for lubrication the
engine must be turned off and the moved areas stable before
approaching.
WARNING
Movement of the superstructure and the boom may
create a crushing and/or pinching hazard. Failure to
observe this warning could result in death or serious injury
if the message is ignored.
