Hoisting and Rigging Practices Flashcards

What is the primary purpose of a lift plan for tower hoisting operations?

Answer: To document the load weight, rigging configuration, equipment ratings, and step-by-step procedure to ensure a safe lift

A lift plan ensures all aspects of the hoisting operation have been thought through and equipment is properly rated.

What is the difference between a bridle hitch and a basket hitch for sling use?

Answer: A bridle hitch uses two separate slings to support a load from above, while a basket hitch wraps a single sling under and around the load

Different hitch configurations provide different load control and capacity characteristics.

Why must hoisting equipment be de-energized and secured when not actively in use on a tower?

Answer: To prevent unauthorized operation, accidental activation, and damage from weather exposure

Unsecured hoisting equipment can be accidentally activated, operated by unauthorized persons, or damaged by weather.

What inspection is required for hooks used in hoisting operations?

Answer: Check for deformation, cracks, throat opening increase, twist, wear on the saddle, and verify the safety latch functions properly

Hook failure during a loaded lift results in an uncontrolled load drop.

What is the proper procedure for receiving a load at the top of a tower?

Answer: Guide the load using a tag line or hands-free technique, ensure personal fall protection is secure, and never position yourself under the load

Receiving a load at height requires proper positioning, secure personal fall protection, and controlled load guidance.

What is a critical lift and what additional precautions does it require?

Answer: A lift involving maximum equipment capacity, irreplaceable items, proximity to hazards, or unusual conditions requiring enhanced planning and supervision

Critical lifts involve higher-than-normal risk factors that require additional planning and supervisory oversight.
