SAFE MAINTENANCE PRACTICES
Read This Manual
To ensure safe and proper operation of Manitowoc cranes,
they must be maintained according to the instructions
contained in this manual.
Authorized Repair Personnel Only
Crane maintenance and repair must be performed by
personnel who by reason of training and experience are
thoroughly familiar with the crane’s operation and required
maintenance. These personnel must read the MLC650
Operator Manual and the MLC650 Service/Maintenance
Manual before attempting any maintenance procedure. If
there is any question regarding maintenance procedures or
specifications, contact your Manitowoc dealer for assistance.
Training/qualification of maintenance personnel is the
responsibility of the crane owner.
Basic Crane Maintenance Safety
The following precautions are basic practices. Detailed
precautions and warnings are in the relevant procedures in
this manual. Be sure to read all information in this manual
that is relevant to the maintenance to be performed.
Before Starting a Maintenance Procedure
Perform the following actions (as applicable) before starting
a maintenance procedure:
•
Park the crane where it will not interfere with other
equipment or operations.
•
Lower all loads to the ground or otherwise secure them
against movement.
•
Lower the boom onto blocking at ground level, if
possible, or otherwise secure the boom so that it cannot
drop unexpectedly.
•
Move all controls to OFF and secure all functions
against movement by applying or engaging all brakes,
pawls, or other locking devices.
•
Stop the engine and render the starting means
inoperative. This can be done by following your
organization’s tagout procedure.
•
Place a warning sign at the start controls to alert other
personnel that the crane is being serviced and the
engine must not be started. Do not remove the sign until
it is safe to return the crane to service.
•
Wear clothing that is relatively tight and belted.
•
Wear appropriate eye protection and an approved hard
hat.
•
Do not attempt to maintain or repair any part of the crane
while the engine is running, unless it is absolutely
necessary.
If the engine must be running while the crane is being
serviced, observe the following:
-
Maintain constant verbal communication between
t h e p e r s o n a t t h e c o n t r o l s a n d th e p e r s o n
performing the maintenance or repair procedure.
-
Keep your clothing and all parts of your body away
from moving parts.
Precautions While Working on the Crane
•
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.
To climb onto and off the crane, use both of your hands
and also use the handrails, steps, and ladders that are
provided.
Use hand lines or hoists to lift tools and other equipment
that cannot be carried in pockets or tool belts.
•
The boom and gantry are not intended for use as
ladders. Do not attempt to climb the lattice work of the
boom or gantry. If the boom or gantry is not equipped
with an approved ladder, lower it before performing
maintenance or repair procedures.
•
Store tools, oil cans, spare parts, and other necessary
equipment in tool boxes. Do not allow these items to lie
around loose in the operator’s cab or on the walkways
and stairs.
•
Pinch points are impossible to eliminate. Watch for them
closely.
•
Do not attempt to lift heavy components by hand. Use a
hoist, jacks, or blocking to lift components.
•
Never handle the wire rope with bare hands. Always
wear heavy-duty gloves to prevent being cut by broken
wires.
WARNING
Safety Responsibility!
The importance of safe maintenance cannot be
overemphasized. Carelessness and neglect on the part of
maintenance personnel can result in their death or injury
and costly damage to the crane or property.
Safety information in this publication is intended only as a
guide to assist qualified maintenance personnel in safe
maintenance. Manitowoc cannot foresee all hazards that
will arise in field. Safety remains the responsibility of
maintenance personnel and the crane owner.
