A utility representative tells the site superintendent that the 12 kV line above the work area has been switched out. Before the crane may work inside the Table A clearance distance for that voltage, the line must be:
Correct answer: A - De-energized and visibly grounded at the worksite
A crawler crane with the boom lowered and no load must travel beneath an energized 45 kV line. What is the minimum clearance that must be maintained?
Correct answer: B - 6 ft
A lattice boom crawler crane carrying 180 ft of main boom is set up 2% out of level, and the load is picked on the downhill side. Compared with the radius the operator charted, the actual working radius will be:
Correct answer: C - Longer, and the error increases as boom length increases
Operating radius is correctly measured as the horizontal distance from:
Correct answer: B - The center of rotation to the center of the vertical hoist line
During operations the anti two-block device stops working properly. A temporary alternative measure is implemented so work can continue. Under OSHA, repairs to the device must be completed:
Correct answer: B - Within 7 calendar days after the deficiency occurs
A running hoist rope is inspected and found to have four randomly distributed broken wires in one rope lay, including two broken wires in a single strand within that lay. No other deficiencies are found. The rope:
Correct answer: A - May remain in service, because neither of the two removal criteria has been reached
A 9,000 lb load is lifted with a two-leg bridle sling. Each leg forms a 30 degree angle with the horizontal. The tension in EACH sling leg is approximately:
Correct answer: D - 9,000 lb
A wedge socket is used to terminate the hoist rope. The termination is installed correctly when:
Correct answer: B - The live end of the rope is in line with the centerline of the pin
A crawler crane is rigged with a fixed jib stowed alongside the main boom. The jib will not be used for the lift. When determining net capacity, the stowed jib:
Correct answer: C - Must be deducted in the exact amount specified by the load chart notes
Two configurations can both place the load at a 70 ft radius: 140 ft of boom at a lower angle, or 100 ft of boom at a higher angle. Compared with the 100 ft boom, the 140 ft boom at that same radius provides:
Correct answer: D - Less capacity, and greater available hook height
