Unit of Study Instruction
SAFETY -- Overview of causes of crane accidents and training
				in managing the work environment safely.
OR-OSHA CRANE RULES -- Familiarity with OR-OSHA'S Division 3,
				Construction, Subdivision N, Cranes, Derricks, Hoists, Elevators, and
				Conveyors.
CRANES AND COMPONENTS -- Types of cranes, names of crane
				components, selection of cranes for job.
DEFINITIONS OF TERMS -- Center of gravity, radius, gross and
				net load, static load and dynamic load(s), effective weights, ultimate strength
				and rated strength, safety factors, stowed and stored, tipping axis, jib angle
				to ground.
TECHNICAL DATA -- Leverage: when using the crane in general,
				the hook, block and the boom hoist. Changes in leverage, rate of tipping,
				forward stability, backward stability, crane failures, gantries, live and high
				masts, counterweights, effect of boom angle, effects of jib angle, jib as a
				boom extension, effect of load on booms, production lifts, rope safety
				factors.
QUADRANTS OF OPERATION DEFINITIONS -- Over the rear, over the
				side, 360 degree rotation.
WEIGHT OF THE LIFT -- Sources of weight data, calculating
				weights, principles examples, lifting in water, tests lifts, check
				lifts.
CONDITIONS & CAPACITIES -- Summary of conditions affecting
				crane capacities: off-level, wind, eccentric reeving, swing out, side loading,
				impact loading, outrigger position, ground conditions, counterweights, gantries
				and high masts, equipment condition, swing bearing wear, tire condition and
				inflation, boom pad wear, outrigger and pad condition, bent chords and
				lacings.
MULTIPLE CRANE LIFTS -- Types of equalizer beams, pivot points
				in lines, pivot points not in-line, load as an equalizer beam, necessary
				calculations.
CALCULATIONS -- Crane capacities: results of over loading,
				division of load charts, gross and net capacity, gross and net load, radius
				between values, boom length between values, boom angle between values, parts of
				line; calculating capacities: on the boom, on the pinned section, on the
				extension, on the jib.
PREPARING FOR A LIFT -- Boom assembly and disassembly, reasons
				to repair/scrap boom sections, Wire rope installation, reeving, wedge sockets,
				telescoping booms, setting-up, measuring radius, radius over boom angle,
				outrigger set-up, block outriggers, leveling methods.
CONDITIONS DURING LIFTS -- Swing out, slack rope on drums,
				pick and carry, lifting on tires, protection of personnel around high voltage
				and results of making contact, working in the vicinity, effects of electrical
				current, hitting booms, boom over back, causes of two-blocking, shift of center
				of gravity, cold weather operation, tipping over backwards.
LEAVING CRANES UNATTENDED -- Short periods, extended
				periods.
RESPONSIBILITIES -- Management and operator
				responsibilities.
MISCELLANEOUS -- Signals, composition of wire rope, rope
				strengths, tables of rates and capacities, determine sling loadings, using
				blocks and tackle.
CRANE CHECKLIST -- Operator's daily checklist.
ERECTION, DISMANTLING, TRANSPORT -- Erection checklist,
				bolting procedures, bolting.
INSPECTION & TESTING -- Frequency of inspections, testing
				maintenance, and storage of crane components.
Complete program includes at least one crane specific class
				  in addition to basic core.
