1. A crane component made by a crane company can be used on any other crane made by that company. False #298 1. A rough terrain crane is commonly referred to as: Cherry picker #301 Brainpower Read More Previous Play Next Rewind 10 seconds Move forward 10 seconds Unmute 0:06 / 0:15 Full screen List the two causes of the majority of mobile crane accidents Improper Assembly #305 b. Improper Setup When lifting boom sections, avoid connecting wire rope slings to the main------ of the boom Chords 1. During crane assembly the counterweight should be installed ______________ the installation of the complete boom. Before #306 1. When assembling the boom sections, which set of pin holes are fastened (pinned) first? Upper #309 1. When installing the boom pins, the pin should be pointing: Out away from boom center #311 1. When first raising an assembled boom what precaution should be observed to reduce the weight on the boom? Run out the hoist line; keep the block on the ground until about 30 degrees. #311 1. When dismantling a crane boom the bottom set of boom pins should be removed first. True #312 1. It is safe to climb under a boom to knock out the boom pins if the crane has tension on the pendant lines. False #313 1. What two important steps must be followed when welding a damaged crane boom? Follow the Manufactures Welding procedures b. Have a welder certified to the correct welding procedures. #315 Which position should the gantry of a crane be in when lifting a load Highest position. #316 A ---- is an auxiliary boom, which is in effect an extension of the main boom. jib When using the main load line (with the jib attached), the working load for the boom must be reduced by: Manufacturers specifications for jib and hook weight reduction. #317 Jib forestay and backstay pendant lines should be: Of equal length, or the backstay pendant lines should be longer. #319 Jib capacity "increases" as the angle to the ground decreases False #320 To avoid torsional loading the boom tip sheaves should be Symmetrically reeved. #323 Whenever operating a crane around newly constructed buildings which of these conditions could be dangerous? Uncompacted soil #327 The ground pressure under outriggers is higher than it is under a crawler track because of a smaller bearing surface. True #330 An outrigger float should be approximately how much larger than the outrigger pad? 3 times #331 A crane sitting 3 degrees off level can increase the boom stress by 50% True #335 The load line is hanging in the dead center of the boom when positioned over the rear. With the boom over the side, the load line is observed to be off center. This means: Not safe to use until level in all positions. #336 Crane stability is based on: Lever principle #337 The center of gravity will vary the most for different lifting positions with which type of crane? Truck cranes #339 Load Moment indicators warn the operator of an overload condition. True #342 List the factors that determine crane capacities. a. Machine Weight b. Stability c. Strength of components #343 Load dimensions could have as much bearing on boom radius as the load weight? True #343 Deflections of the boom and pendant stretch will increase: Load radius #345 When raising a long boom off the ground, what will avoid excessive pendant pull and boom compression? A second crane to help lift boom #348
