APPROVED LUBRICANTS FOR ARCTIC
OPERATION
The lubricants listed in Table 3 are recommended for use in
Manitowoc’s line of hydraulic cranes when operating in an
arctic-type climate
—climates with an outside
temperature continuously between -18°C (0°F) and -40°C
(-40°F).
Use these lubricants in place of the lubricants listed for
normal operation in this section.
Additionally, the crane should have hydraulic tank heaters
available from Manitowoc Crane Care Lattice Team.
Table 3 Lubricant for Arctic Operation
CAUTION
Machinery Damage!
Do not operate the main crane functions (swing, travel,
drums, boom hoist) with approved arctic lubricants when
the ambient temperature is above 16°C (60°F). Crane
machinery will be damaged.
When the ambient temperature is above 16°C (60°F), limit
operation to the crane setup functions (that is, jacking
cylinders).
When the ambient temperature is expected to remain
above 16°C (60°F), drain the arctic lubricants and refill
with the lubricants recommended for normal operation.
Structural Damage!
Cold weather can affect the structural integrity of the
crane and attachment. Before operating in cold weather,
read the Cold Weather Operation —Crane Limitations
topic in Section 3 of the Crane Operator Manual.
