Arctic Conditions Below -18° C (0° F)
In general, petroleum based fluids developed especially for
low temperature service may be used with satisfactory
results. However, certain fluids, such as halogenated
hydrocarbons, nitro hydrocarbons, and phosphate ester
hydraulic fluids, might not be compatible with hydraulic
system seals and wear bands. If you are in doubt about the
suitability of a specific fluid, check with your authorized
Grove Cranes distributor or Manitowoc Crane Care.
Regardless of temperature and oil viscosity, always use
suitable start-up procedures to ensure adequate lubrication
during system warm-up.
CYLINDER ROD SURFACE PROTECTION
Steel cylinder rods include a thin layer of chrome plating on
their surfaces to protect them from corroding. However,
chrome plating inherently has cracks in its structure which
can allow moisture to corrode the underlying steel. At typical
ambient temperatures, hydraulic oil is too thick to penetrate
these cracks. Normal machine operating temperatures will
allow hydraulic oil to warm sufficiently to penetrate these
cracks and if machines are operated daily, protect the rods.
Machines that are stored, transported, or used in a corrosive
environment (high moisture, rain, snow, or coastline
conditions) need to have the exposed rods protected more
frequently by applying a protectant. Unless the machine is
operated daily, exposed rod surfaces will corrode. Some
cylinders will have rods exposed even when completely
retracted. Assume all cylinders have exposed rods, as
corrosion on the end of the rod can ruin the cylinder.
It is recommended that all exposed cylinder rods be
protected using Boeshield® T-9 Premium Metal Protectant.
Manitowoc Crane Care has Boeshield® T-9 Premium Metal
Protectant available in 12 oz. aerosol cans by ordering part
number 9999101803 through the Parts Department.
Cylinder operation and inclement weather will remove the
Boeshield® protectant; therefore, inspect machines once a
week and reapply Boeshield® to unprotected rods.
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. 1 oz (0.28 kg) of EP-MPG equals
one pump on a standard 1 lb (0.45 kg) grease gun.
Over lubrication on non-sealed fittings will not harm the
fittings or components, but under lubrication 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.
