A) There is no minimum B) 4 full wraps, 2 full wraps C) 2 full wraps, 3 full wraps D) 6 full wraps, 4 full wraps E) 1 full wrap, 2 full wraps The horizontal distance from the center of rotation of the crane to the center of the hoist line(s) with load applied is called A) Boom Length B) Radius C) Lift Zone D) Quadrant E) Circumference What is two-blocking, and why is two-blocking dangerous? A) Two-blocking occurs when the hook contacts another block or hook on the crane. It is dangerous because the hook could damage the crane, causing loss of load control. B) Two-blocking occurs when the block or hook contacts the ground. It is dangerous because the wire rope may come off of the drum and drop the block. C) Two-blocking occurs when the hook block comes in contact with the upper sheave block during hoisting of the hook. It is dangerous because it could result in damage to the crane, parting of the hoist lines, and dropping the load. When should a tagline be used during lifting operations? A) when lifting a load over or near electrical transmission lines B) to prevent the load from swinging or rotating C) when the supervisor approves their use D) only when lifting the load to extreme heights What is the weight of a 24 square foot, 2 inch thick aluminum plate with a unit weight of 15 lbs. per square foot of material per inch of thickness? A) 348 pounds B) 720 pounds C) 6,720 pounds D) 60 pounds E) 120 pounds The two expiration dates that are of particular importance to crane operators are- A) Vehicle registration expiration date B) Hydraulic oil expiration date C) CAC card expiration date D) The certification expiration date of the crane E) The crane operator's license expiration date Which of the following is NOT an acceptable method of communication between the signal person and the crane operator? A) Signal Flags B) Direct Voice C) Hand Signals D) Sound-powered Phones E) Approved Radios What is a jib boom? A) A boom that is attached to the main boom to allow rotation of the load B) An extension attached to the main boom used when lifting light loads to a higher elevation than that permitted by the main boom C) A boom that is used to lift extremely heavy loads If you find cracking or flaking paint on a welded joint of a structural component on the boom, you should A) Look closer to see if it is a crack. B) Report it immediately to your supervisor. C) Do nothing as it is not significant. D) Make a mental note to investigate it later. E) Note it on the ODCL, but do not report it. While performing a pre-use check, the operator must check the wire rope system for all of the following EXCEPT- A) Excessive corrosion B) Damage of any kind C) Size and grade of wire rope D) Proper sheave movement E) Proper spooling on the drum All of the following are principle parts of an overhead traveling crane EXCEPT- A) Operator's cab or pendant control B) End trucks C) Shackles and eyebolts D) Bridge girders E) Trolley with hoisting mechanism If you find a deficiency that will affect the safe operation of the crane during the pre-operational check, all of the following actions must be taken EXCEPT- A) Operate that specific function again to ensure there is a problem B) Notify your supervisor C) Note the finding on the ODCL D) Secure the crane E) Follow supervisor's instructions Components that provide protection for operation and maintenance personnel working on or in the path of cranes are? A) Operational Safety Devices B) Alterations/Modifications C) Load Controlling Parts D) Load Bearing Parts E) General Safety Devices When setting up mobile cranes, the minimum clearance between the rotating upper works and fixed objects should be? A) 1 foot B) 2 feet C) 3 feet D) 4 feet E) 5 feet The rated load of the hook block installed on a crane may limit the crane's lifting capacity. A) True B) False When crane accidents happen or damage is found, you must do all of the following EXCEPT A) Continue operating until the supervisor performs an evaluation B) Put the load in a safe condition C) Standby for instructions D) Stop operations E) Contact your supervisor When should the rotate locking device be engaged on a mobile crane? A) when hoisting a load B) while the crane is traveling with a load in "pick and carry" mode C) any other time required by the crane OEM D) when landing a load E) whenever using the LMI system F) whenever the operator leaves the cab In cold weather operation, what precautions should be taken during the pre-operational check or ODCL to avoid damage when sheaves may be frozen? A) Check the hoist and boom lower limit switches first B) Hoist down first and check the lower limit switch C) Raise the blocks and boom before lowering them D) Lower the boom prior to raising it E) Lower the blocks prior to raising them If the crane operator and the Rigger-in-Charge disagree on whether or not a load is safe to lift, the operator should- A) Follow the instructions of the Rigger-in-Charge B) Note the incident on the back of the ODCL card C) Not operate the crane until contacting the supervisor to resolve the issue D) Proceed slowly with extreme caution E) Tell his or her supervisor at the end of the shift Components that control, restrain, or position the load and upon failure W would cause dropping, shifting, or uncontrolled movement of the load are A) Alterations and/or modifications B) Operational safety devices C) Load bearing parts D) Load controlling parts E) General safety devices The Rigger-in-Charge has primary responsibility for determining the weight of an object to be hoisted; however, the operator must be satisfied that the estimated weight to be lifted will not exceed the safe load carrying capacity of the crane.
