2026. QUESTIONS AND CORRECT
VERIFIED ANSWERS. GRADED A
A frequent inspection or pre-operational inspection is: -ANS The
responsibility of the crane operator
A multi-crane lift plan must include the following requirements: -ANS All
personnel involved in the operation must be qualified to perform their duties
All personnel must be instructed in all phases of the operation
The ground or supporting surface must be capable of supporting the weight
of both the crane and its load
All cranes must be set up on mats or blocking
All cranes must be level and positioned properly
The load weight imposed on each crane must be accurately determined
Each crane's net capacity must be determined exactly
All movements must be made in a slow and controlled manner
Consider reducing each crane's net capacity
All running ropes should be: -ANS Inspected at least daily
Avoid setting up near buildings under construction and... -ANS near
trenches, excavations, shoring locations, underground pipes, sewers,
tanks,...

, Backward stability factors -ANS Operating over the side, no load, shortest
boom length maximum boom angle, and load on wheels
Blocking should be at least... -ANS three times the surface area of the pad
and be bolted together without gaps between the blocks
Blocks that are not symmetrically reeved will: -ANS Tilt
Boom angle is: -ANS The angle between the center line of the base boom
and the horizontal after the load is lifted
Boom deflection will: -ANS Decrease boom angle and increase load radius
Boom torque is minimized in multi-part reeved systems, if... -ANS the parts
of line are evenly distributed on either side of the boom center line.
Capacity charts are normally divided by: -ANS Using a bold line, asterisks,
or shaded area
Capacity is limited by: -ANS The lowest rated component
Check the crane for: -ANS Boom sway, droop, bulges, creases, waviness,
worn wearpads, hydraulic leaks, and the poor condition of the sheaves,
pendants, end fittings, hoist ropes, outriggers, and frame. All can lower
capacity
