MLC90A-1/MLC100-1 OPERATOR MANUAL SAFETY INFORMATION
CRANE ACCESS POINTS
General
Take necessary precaution to prevent slipping and/or falling
off the crane during assembly, disassembly, maintenance, or
other work. Falling from any height could result in
serious injury or death.
Manitowoc has provided ladders and platforms at the
locations shown in Figure 2-1.
The owner/user shall provide workers with approved ladders
or aerial work platforms to access those areas of the crane,
mast, and boom that cannot be reached from the ground or
from steps, ladders, catwalks, and platforms provided by
Manitowoc.
Adhere to local, state, and federal regulations for handling
personnel and for personnel fall protection.
• Access points must be kept clear to prevent personal
injury and unsafe operation of the crane. Store clothing
and other personal belongings so they do not interfere
with controls in operator cab or with operation of the
crane.
• Do not allow ground personnel to store their personal
belongings (clothing, lunch boxes, water coolers, and
the like) on the crane.
This practice will prevent ground personnel from being
crushed or electrocuted when they attempt to access
personal belongings stored on the crane.
• Tools, oil cans, spare parts, and other necessary
equipment must be stored in tool boxes or other
appropriate locations. Do not allow these items to lie
around loose in operator cab or on steps, ladders,
catwalks, and platforms.
• To reduce risk of slipping, non-skid material (sand in
paint) has been applied to painted walkways and
platforms.
• Walkways and platforms can be slippery when wet and
when oil or is grease is spilled on them. Keep walkways
and platforms clean and dry to prevent slipping on
them. When non-skid material wears out, reapply it.
• Wear shoes with a highly slip-resistant sole material.
Clean any mud or debris from shoes before entering the
crane cab or climbing onto the cab. A shoe that is not
clean might slip off a control pedal during operation.
• Do not make modifications or additions to the crane’s
access system that have not been evaluated and
approved by Manitowoc.
GETTING ON OR OFF CRANE
Personnel getting on and off the crane shall do so only at the
ladders provided and only while the crane is parked.
Never climb onto or off a moving crane. Climb onto and off
the crane only when it is parked and only with the
operator’s permission.
When personnel use ladders to get on or off the crane, their
hands shall be free of any objects. Objects which cannot be
carried in pockets or tool belts shall be lifted into place with a
hand line or hoist.
Always maintain a three-point contact with the ladder: two
feet and one hand of two hands and one foot.
PERSONAL FALL-PROTECTION
It is the crane owner/user’s responsibility to provide
assembly/maintenance personal with appropriate fall-
protection equipment.
WARNING
Crush Hazard!
The upperworks can swing into and crush personnel
climbing on or off the crane.
Moving crawlers can crush personnel climbing on or off
the crane.
To prevent death or serious injury:
• Barricade all accessible areas to the crane so
personnel cannot be struck or crushed when the
upperworks is swung.
• Do not climb onto or off the crane while the
upperworks is being swung or the crane is being
traveled.
• Signal the operator for permission to climb onto/off
the crane.
• Operator: do not swing or travel while personnel are
climbing onto or off the crane. Stop the swing and
travel motions. Apply the swing brake and turn on
travel park.
• Operator: Always sound the horn to alert personnel
before you swing or travel.
• Automatic alarms will sound to alert personnel when
the crane is swung or traveled.
NOTE If the swing and travel alarms are not operating
properly, they must be repaired as soon as
possible. Until they are repaired, the operator
shall alert personnel to crane movement using
the horn on the control console.
