Presentation Transcript

  1. Visual Inspection • Look for crane tags • Look for physical damage • Check hoist chain and wire rope • Make sure wire rope is seated in drum and sheave grooves • Look for disconnect switch.

  2. Operational Inspection • Move crane several feet in each direction • Unusual noises and jerky movements • Control station and switches work correctly • Lower hoist block to make sure at least 2 turns of rope remain on drum • Hook has a safety latch and it’s not stretched.

  3. Rigging the Load • Determine crane’s lifting capacity • Is load within weight limit?

  4. Load Weight Determine with: • Material weight charts • Dynamometer • Estimates.

  5. Rigging Gear • Select gear within safe working load (SWL) of the rope • Inspect rope before use • Check end fittings • Other rigging gear within load-lifting capacity • Replace any item if in doubt.

  6. Slings • Load balance determines location and number of slings needed. • When using more than 1 sling, consider the angles. • Never have a sling angle of less than 90 degrees.

  7. Lifting and Moving • Make sure hands are clear of potential pinch points • No one is positioned between load and another object • Slowly raise hoist block to remove slack • Slings are fully seated • Lift load a few inches to check rigging • Lift load high enough to clear obstructions.

  8. Big Capacity Cranes Communicate with operator • Standard hand signals found in ANSI B30 • Radio.

  9. Don’ts • Jog controls unnecessarily • Use pendant control station to swing jib boom into place • Leave suspended load unattended • Pass load over people or allow anyone to walk under it.

  10. Don’ts continued • Pull a load • Get distracted • Allow unused slings or ropes to remain on the hook • Leave hoist block low enough to hit someone.
