01Site and Equipment Inspection
A site and equipment inspection is really two inspections: the ground/site and the crane. Walk the travel path and setup area for soft spots, voids, uncompacted fill, slopes, excavations, buried utilities, overhead lines, and swing or clearance hazards.
258 words, about 1 min02Crane Setup and Configuration
The load chart is valid only for the configuration actually on the crane. Setup and configuration include outrigger spread (full, partial, or retracted), blocking and mats, level condition, boom length and telescoping mode, jib stowed or erected, counterweight, auxiliary head, number of parts of line, and tire pressure for on-rubber work.
278 words, about 1 min03Crane Operation
Operation starts with a pre-lift meeting: confirm load weight, rigging, radius, chart, signal person, travel path, and environmental limits. Keep the hoist line vertical; side loading, dragging, and shock loading can collapse a boom or tip a crane.
237 words, about 1 min04Load Chart Use and Capacity Determination
Load charts give gross capacity for a specific radius, boom length, angle, quadrant, outrigger condition, counterweight, and parts of line. To find the allowable load, subtract from gross capacity everything that hangs from the boom: hook block or ball, slings, shackles, spreader bars, buckets, and personnel platform.
247 words, about 1 min05Communication and Hand Signals
Effective communication prevents most crane accidents. The signal person must be qualified and positioned to see the load, the operator, and the path.
234 words, about 1 min06Safety, Standards, and Operator Responsibilities
The operator is responsible for safe operation and has stop-work authority. Know and follow OSHA 1926 Subpart CC, ASME B30.5, the manufacturer's manual, and the load chart.
