CRAWLER BLOCKING
To prevent the crane from tipping, some boom and jib
lengths require blocked crawlers. See the appropriate
Liftcrane Boom or Jib Capacities chart for blocked crawler
requirements.
For crawler blocking dimensions and instructions, see the
Crawler Blocking topic in the Capacity Chart Information folio
located in the Capacity Chart Manual supplied with the
crane.
PREPARING CRANE FOR OPERATION
DANGER
Tipping Hazard!
Do not attempt to raise or lower the boom or the boom
and jib from or to ground level until the crawlers are
blocked, if required. Otherwise, the crane will tip.
WARNING
Read Capacity Charts
Do not attempt to operate the crane without first reading
and understanding the capacity charts located in the
Capacity Chart Manual provided with the crane.
The crane must be rigged and operated according to the
instructions given in the capacity charts and in Section 4
of the Operator Manual.
Unless otherwise specified in the capacity charts, all
crane operations must be performed with the crane level
to within one 1% of grade in all directions — 0,3 m in 30 m
(1 ft in 100 ft); otherwise, crane could tip.
Do not operate the crane—including raising the boom
from ground level—if the wind speed exceeds the limits
given in the capacity charts. Contact your local weather
station for the wind velocity in your area.
Failing to comply with the requirements of the capacity
charts can result in tipping or structural failure of the boom
or jib.
Equipment Failure Hazard
At low ambient temperatures, dynamic loads (impact and
shock) can affect the steels used in Manitowoc cranes
when operating in cold weather. Read and comply with
Cold Weather Operation on page 3-52
before operating
the crane.
WARNING
Moving Load Hazard
The operator shall select the proper crane capacity chart
in the RCL/RCI Display before operating.
Unexpected drum motion or improper limit responses can
result if the wrong capacity chart is selected.
The limit bypass switch shall be in the enable position (on)
and all the limits with which the crane is equipped shall be
operational before operating the crane.
Avoid Injuring Personnel in Operating Area
Sound the horn to alert personnel that operation is about
to begin.
WARNING
Moving Machinery Hazard
To avoid injuring personnel or damaging the crane and
property:
• Do not start the engine if an out-of-order sign or do
not operate tag is present at the start controls.
• Check that all controls are off and parked so the
crane and load do not move when the engine is
started.
• Check that all personnel are clear of the crane before
starting the engine. Sound horn to alert personnel.
Engine Explosion Hazard
Do not use starting fluids with this crane’s engine. The
engine is equipped with an air intake heater. Use of
starting fluid can cause an explosion, fire, personal injury,
severe damage to the engine and damage to property.
CAUTION
Machinery Damage Hazard
Before operating the crane at the start of each shift:
• Perform the preventative maintenance checks and
lubrication requirements listed in Sections 5 and 6 of
the this manual.
• Adjust the operator’s seat. See Seat Controls on
page 3-24.
