COMMUNICATIONS:
Few job-site conditions are as important to the safety
of the lift than the communications between the operator and the
individual(s) controlling the lift. During this session participants
discuss the importance of clear and concise direction, whether it
is in the form of audio or visual communications. The qualifications
and responsibilities of the "Designated" signal person
are discussed.
RIGGING
HARDWARE: This session deals with various types of rigging
hardware commonly used in the craning industry. Identification,
inspection procedures, application and removal from service criteria
are presented through video and hands-on demonstration.
SLING SELECTION
AND APPLICATION: During this presentation and in-class
exercises, participants learn how to select, inspect and apply various
types of slings and determine the safe working load that can be
applied to them. The effect that the sling's angle to the load has
on its rated capacity is discussed and calculations are made to
determine actual and Safe Working Loads.
DETERMINING
LOADS' CENTER OF GRAVITY: This segment emphasizes the
importance of knowing the location of the loads center of gravity
to assist in the selection of the proper rigging necessary to produce
a "stable" load when lifted. It is important also to recognize
what happens to the center of gravity of a load once the load is
lifted into the air.
EQUALIZER
AND SPREADER BEAMS: The difference between equalizer
and spreader beams and their particular applications are studied.
With equalizer beams the class participants learn, through practical
exercises and lift simulation, how the load is proportionally shared
between the cranes making the lift and how these proportions can
be altered to suit the crane capacities available by adjusting the
location of the load on the beam.
MULTIPLE
CRANE LIFTS: The extra precautions such as avoiding
shock and sideloading of the booms when the use of multiple cranes
is necessary to make a single lift are studied. As part of the pre-lift
planning the class discovers through practical exercises how to
determine what the actual load on each of the cranes will be throughout
the lift process. The class also learns how the load sharing on
the cranes can be altered by manipulating the lift points.
HANDS-ON
APPLICATION: Through hands-on exercises participants
learn the proper selection and application of various types of slings
and rigging hardware.
GENERAL
KNOWLEDGE TEST: At the conclusion of this training program
participants are required to complete a written course test. This
test will be of the open book type but will still challenge the
individuals' knowledge of rigging principles and applications.
CERTIFICATE
OF COMPLETION: Certificates of completion are awarded
to those course participants who "successfully complete"
the course test.
