  1. On a luffing jib tower crane, how is the working radius changed?

    Answer: By raising or lowering the angle of the entire jib

    A luffing jib changes radius by varying the jib's angle of inclination rather than moving a trolley.

  2. When climbing a tower crane using an internal climbing frame, what must be verified before beginning the climb?

    Answer: The slewing ring must be locked, load removed, and climbing frame properly seated

    Before internal climbing, the slewing must be locked, the hook must be empty, and the climbing frame must be properly engaged to safely insert a new mast section.

  3. What is the function of the counter-jib on a top-slewing tower crane?

    Answer: It carries the counterweight and hoist machinery to balance the load jib

    The counter-jib extends opposite the load jib and carries counterweights plus the hoist motor to balance the crane.

  4. According to OSHA 1926.1416, how often must a tower crane's wire rope be inspected?

    Answer: Before each shift by the operator and periodically by a qualified person

    OSHA requires a visual inspection by the operator before each shift and periodic inspections by a qualified person based on service conditions.

  5. A tower crane is equipped with a 'dead man' control. What does this mean?

    Answer: Controls automatically return to neutral when the operator releases them

    Dead man controls require continuous operator pressure; releasing them causes all motions to stop and brakes to engage.

  6. What information is found on a tower crane's load chart that is NOT found on a mobile crane load chart?

    Answer: Specific mast height configurations affecting maximum tip capacity

    Tower crane load charts often include capacity reductions tied to specific mast heights because taller free-standing configurations affect structural ratings.

  7. During tower crane operations, a signal person gives a circular motion of the finger pointed upward. What does this signal mean?

    Answer: Hoist the load

    A circular upward finger motion is the standard ASME B30.3 signal for 'hoist' — raise the load.
