2250 OPERATOR MANUAL SAFETY INFORMATION
after safety concerns have been addressed or if the
continuation of crane operations is directed by the lift
supervisor.
• The operator shall be thoroughly familiar with the
operation of the crane and its proper care. If adjustments
or repairs are necessary or if there are known defects
that impair safe operation, the crane must not be
operated until unsafe conditions have been corrected.
• If there is a warning sign at the start controls, the
operator shall not start the engine until the warning sign
has been removed by the person who installed it.
Pre-Start Checks
Before starting the engine, the operator shall perform the
following checklist:
o All daily inspection and maintenance services have
been performed.
o All controls are in the OFF position and all brakes and
locking devices are applied or engaged.
o All personnel are clear of the crane. Deploy a swing
radius barrier.
o The operator shall test all controls, limits, and
communication systems at the start of each shift. Any
defects found must be corrected before operation is
begun.
o The operator shall not start crane movement if the load
or designated signal person is not within his/her range of
vision or communication.
NOTE: The operator shall obey a stop signal at all times,
regardless of who gives it.
o The operator shall understand and respond to signals
from the person directing the lift or from the designated
signal person. When a signal person or crane follower is
not required, the operator is responsible for the lift.
o The operator shall verify that the Capacity Chart being
used is the correct one for the crane’s configuration
(boom length, load line reeving, counterweight).
The operator shall verify the following:
o All attachments are properly assembled and attached to
the crane according to the rigging drawings called for in
the Capacity Chart.
o The counterweight—to include applicable auxiliary
counterweight—is in place and of proper weight. The
maximum required counterweight must not be
exceeded.
Leaving the Operator’s Cab
The operator shall perform the following operations before
leaving the operator’s cab for any reason.
1. Park the crane and position the upperworks so that the
crane does not interfere with operation of other
equipment.
2. Apply travel and swing brakes or locking devices.
3. Land any attached load.
4. Lower the boom onto blocking at ground level or onto a
boom rest if possible.
If the boom cannot be lowered, as determined by a
qualified designated person, it must be securely
fastened from movement by wind or other outside
forces. See Wind Conditions in the Capacity Chart
Manual.
NOTE: The designated person shall be familiar with the
jobsite limitations, the crane configuration, and the
expected weather conditions.
5. Place all controls to the OFF position.
6. Apply all drum brakes and pawls.
WARNING
Acknowledge All Safety Devices and Operational
Aids!
Safety devices and operational aids, such as a rated
capacity indicator or limiter, boom and jib angle indicator
or limiter, anti-two-block device, level indicator, swing
limiter, and proximity device, may be installed on your
crane. Such devices are to be used only as aids to assist
the operator. Their presence on the crane in no way
substitutes for or lessens the requirement that operator
knowledge, experience, and judgment are required to
ensure safe operation of crane.
The Crane must not be loaded beyond applicable static or
dynamic ratings given in the Capacity Chart for the crane.
• See Size of Load on page 2-10
for more information.
• For a description of each safety device and
operational aid, see Safety Devices on page 2-14
,
and Operational Aids on page 2-15
for more
information.
WARNING
Moving Load/Tipping Crane Hazard!
Changing weather conditions including but not limited to
wind, ice, must be considered when determining the
location and configuration of a crane when it will be left
unattended.
