What is the primary purpose of a crane load chart?
Answer: To define the maximum load capacity at various radii and boom configurations
A load chart specifies the crane's rated lifting capacity at varying radii, boom lengths, and configurations to prevent overload.
When reading a crane load chart, 'radius' refers to:
Answer: The horizontal distance from the crane's centerline of rotation to the center of the load
Radius is the horizontal distance from the crane's rotation centerline to the load's center of gravity, which directly affects rated capacity.
A pre-lift meeting is required by OSHA 1926.1431 for which type of lift?
Answer: Critical lifts and multiple-crane lifts
OSHA 1926.1431 mandates a pre-lift meeting and written plan for critical lifts and operations involving multiple cranes.
Which factor is NOT typically included in a pre-lift plan?
Answer: Operator's personal credit score
Personal financial information is irrelevant to crane safety; a pre-lift plan focuses on equipment, rigging, ground, and personnel factors.
What percentage of the crane's rated capacity is typically used as the threshold to define a 'critical lift' under many OSHA and industry guidelines?
Answer: 75%
A lift exceeding 75% of the crane's rated capacity is commonly defined as a critical lift requiring a written plan and pre-lift meeting.
Before beginning any lift, the operator must verify the load weight by:
Answer: Consulting load documentation, lift tickets, or engineering calculations
OSHA requires operators to know the load weight through documentation, calculations, or engineering data — not estimates — before lifting.
