Graded A+ A competent person must ____ before each shift. - ANSPerform a visual inspection of equipment. A critical lift is? - ANSA lift at 75% of equipments rated capacity. Also, critical lifts can be expensive, hard to replace, or awkward. Annual Inspections must be performed by? - ANSA qualified person. Must include functional testing. Inspection records must be kept for 12 months. Name, SIG, date of inspection and results.

Before starting the engine operator must ensure that? - ANSAll Controls are in the proper position and ensure all personnel are in the clear. Best Leveling Surface On Crane? - ANSUpper works. Boom Hoisting drum Must? - ANSBe at Least 15x The Nominal Wire Rope Diameter Used. Cantelever Boom Sections Must? - ANSNot exceed mfg limitations and instructions for boom lengths. Cranes 3° out of level will? - ANSDecrease capacity by as much as 50%. Plus add to excessive boom side loading and sheeve wear. Level not to exceed <1° Cranes/Equipment Manufactured After Mar-29-2003? - ANSMust have LMI, (Load Moment Indicator), Or similar device if lift capacity is over 3tons (6000lbs). Distance from Excavations? - ANS1.5 ratio, I.E 10' Deep Excavation 10x1.5=15' from outrigger pad. Newly Compacted Soil near walls is a 1-1 ratio. Eccentric Block Reeving Causes? - ANSTwisting of Boom. Reeving wire to one side of the block or boom hoist sheaves causes twisting of Boom.
