as: 2 / 4

(A) Net loads (B) Gross loads (C) Dynamic loads (D) Static loads - Answer>>(D) Static loads The capacities in a mobile crane's load chart are based on either

structural or:

The values listed in the manufacturer's load chart show:

(A) rated capacities.(B) duty cycle capacities.(C) gross loads.(D) net capacities. - Answer>>(A) rated capacities.

Net capacity is:

(A) manufactures load ratings minus capacity deductions.(B) net load minus gross capacity.(C) net load plus gross capacity.(D) capacity deductions minus gross capacity - Answer>>(A) manufactures load ratings minus capacity deductions.

When determining the "gross load" the best method is:

The boom angle indicator indicates the booms angle to the:

(A) Crane (B) Horizontal (C) Vertical (D) Ground - Answer>>(B) Horizontal

Load radius is defined as: the horizontal distance from the

centerline of rotation to the centerline of the vertical ha line with:

(A) no load on the hook.(B) the rated load suspended.(C) the rigging not Included.(D) 95% load on the hook. - Answer>>(B) the rated load suspended.
