When making a multiple crane lift, it is important for the operator to understand that: The weight may increase if the other crane lands the load If a crane is not set-up level and the operator swings a load from the high side to the low side, the load radius will: Increase Brainpower Read More Previous Play Next Rewind 10 seconds Move forward 10 seconds Unmute 0:08 / 0:15 Full screen Most crane manufacturers reduce load capacity for duty-cycle operations because: Side loading forces may occur On who's recommendations should a preventative maintenance program be set-up? Crane manufacturer What is the standard rope used on most cranes? Right regular lay The proper way to calibrate a boom angle indicator is: Using a level, raise the boom to horizontal and set the indicator at 0 degree. The red area of an instrument gauge means: A dangerous condition exists The best way to keep people from being injured from the counterweight of the crane is to: Fence or barricade the swing area of the crane Only approved attachments or extra counterweights made by the manufacturer should be placed on the rear of the crane because: They could cause a backward stability problem What is the first thing an operator should do before going under a low pipe rack? Post a signalperson to check clearance When working on outriggers, the only time they should be less than fully extended is when: There is a load chart for this operation When lifting loads from the water, the operator should be aware that: The load will increase when you pick the load from the water What is require to be on a Hydraulic Crane in order for it to lift a man basket? Boom length indicator When working on rubber, cranes are rated at what percentage of tipping? 75% When using cable or nylon spreaders, it is important to remember: The lower the spreader angle the greater the tension Backward stability of a crane is tested with: Basic boom at maximum angle with maximum load If not listed in the load/capacity charts for a hydraulic crane, and you are in between boom lengths, you should: Use the next longer length or shorter with less capacity When a spinning load presents a danger, the operator should: Use a tagline The jib capacity is 8 tons and the ball weighs 900 lbs. What is the heaviest load that can be lifted safely? 15,100 Parts of line means: The number of lines running thru the load block If a jib is erected but not being used, it is treated as a deduction from the cranes: Gross capacity What is the maximum number of broken wires before replacement on a standing wire rope? 2 What are most jibs capacities based on? Structural On the majority of conventional cranes, the power is transferred to the torque converter by a: Master clutch During disassembly of a long boom, the hog lines are connected at the maximum cantilever point and the boom is slightly lifted off the ground. Which pins are to be removed next? The bottom pins ahead of the cantilever point When using load/capacity charts, what does the term 'A jib angle to ground' refer to? Main boom angle minus the jibs offset A truck crane, with outriggers properly set, is rated at what percentage of its tipping capacity? 85% On a truck crane with the outriggers extended and set, and tires touching the ground, the operator should refer to what load chart? On rubber chart When testing a man basket how long must the test pick be maintained? 5 minutes What is the minimum pitch diameter for load hoisting sheaves? Not less than 18 times rope diameter What is the minimum pitch diameter for boom hoisting sheaves? Not less than 15 times rope diameter What is the minimum pitch diameter for load block sheaves? Not less than 16 times rope diameter Seat belts shall be provided on what cranes? Cherry Pickers Power is transferred to the swing through a Pinion gear LMIs shall be installed on cranes with a lifting capacity of: 3 ton and above When lifting personnel, the cranes hook must be the type that: can be closed and locked When working over water with a man basket, are the people inside required to wear a belt/harness? No harness or belt required What is the maximum advisable wind speed for crane operation? 30 mph mobile
