A frequent inspection is: - ANSWER Daily to monthly
1. What action does a signal person intend the operator to perform if he extends his arm at shoulder height,
makes a fist with his hand, and sticks his/her thumb up? - ANSWER Boom Up
(Appendix A to Subpart CC of Part 1926--Standard Hand Signals)
2. When hoisting personnel, within what percentage of level must a telescopic boom crane be in order for the
gross ratings in the load chart to remain valid? - ANSWER 1%
(1926.1431(c)(1)
The equipment must be uniformly level, within one percent of level grade, and located on footing that a qualified
person has determined to be sufficiently firm and stable.)
3. The load line of the crane you're operating contacts an energized power line. There's no sign of any other
danger, such as fire. What should you do? - ANSWER Stay in the cab until the lines are de-energized.
, Which area do truck cranes without a 5th outrigger generally have no lifting capacity unless the manufacturer
states otherwise? - ANSWER The front
What is the definition of "operating radius?" - ANSWER The distance from the center of rotation of the crane to
the center of gravity of the load
Unless the manufacturer states otherwise, what crane capacity chart is appropriate when a crane is set up with 3
of its 4 outriggers extended and the fourth is retracted? - ANSWER On-rubber chart
According to OSHA, while hoisting personnel, the total load must not exceed what percentage of the crane's rated

What may happen to a properly rigged load when lifted off the ground unless the operator takes account of boom
deflection - ANSWER It could swing out away from the crane
