Use particular care to ensure that cranes being operated in
very cold temperatures are operated and maintained in
accordance with the procedures as provided by Grove.
Cranes should have appropriate hydraulic oil, lubricants, and
other auxiliary items required for operation in sub-zero
temperatures. Individual crane functions should be operated
to ensure they are sufficiently warmed prior to performing a
lift.
Operation of cranes at full rated capacities in temperatures
between -18°C (0°F) and -29°C (-20°F) or lower should be
accomplished only by competent operators who possess the
skill, experience, and dexterity to ensure smooth operation.
Shock loading shall be avoided. Refer to the following
paragraphs for cold weather operation of cranes down to -
40°C (-40°F).
Derated capacities for each °F below -40°F
Derate the rated load shown on the capacity charts 2 percent
for each degree Fahrenheit below -40°F.
NOTE: Contact your local distributor or Manitowoc Crane
Care to determine requirements and lift solution for
operation down to -40°C (-40°F).
Derated capacities for each °C below -40°C
Derate the rated load shown on the capacity charts 3.67
percent for each degree Celsius below -40°C.
Grove recommends the crane be equipped with the following
cold weather accessories:
Down to -29°C (-20°F)
• Battery heater
• Fuel line heater
• Engine hood insulation
• Fan clutch
• Radiator air shutters
• Air diverter
• Diesel fired cab heater
• Cold weather alternator
• Fluids suitable to -29°C (-20°F)
Down to -40°C (-40°F)
• Coolant heater (to circulate warm coolant through
heaters and engine)
• Transmission heater
• Swivel heater
• Battery heater
• Fuel line heater
• Engine hood insulation
• Fan clutch
• Radiator shutters
• Air diverter
• Diesel fired cab heater
• Cold weather alternator
• Super-capacitor starting system
• Fluids suitable to -40°C (-40°F)
Individual crane functions should be operated to ensure they
are sufficiently warmed prior to performing a lift. Allow at
least 30 minutes of engine run time for warm up.
COLD CLIMATE OPERATION
NOTE: Additional information regarding cold weather
engine operation is available through your
Cummins dealer/service center under Service
Bulletin 3379009.
Crane Warm-up Procedures
The following procedures detail the actions that must be
taken to properly warm the different crane components
before operating the crane.
NOTE: For temperatures below -9°C (15°F) refer to arctic
lubricants and conditions in the Operator and
Service Manuals.
Before starting the crane, ensure the appropriate lubricants
are used to provide lubrication for the prevailing ambient
temperatures in which the crane will operate in (a list of
lubricants and their temperature ranges can be found in the
Lubrication section of your crane’s Operator Manual, by
contacting your local Manitowoc distributor, or by contacting
Manitowoc Crane Care directly).
CAUTION
Crane Damage Hazard!
Operating the crane with the incorrect lubricants and
fluids for the prevailing ambient temperature and/or failing
to adequately warm the crane prior to cold weather
operation can lead to a failure of a crane component or
system.
Always use Manitowoc recommended lubricants and
fluids for the prevailing ambient temperature and properly
start and warm the crane using the cold weather
procedures found in this Operator’s Manual and
supplement before operating the crane at full load.
