ballast: weight used to supplement the weight of the machine in providing stability for lifting working loads (the term ballast is normally associated with locomotive cranes).
base (mounting): the traveling base on which the rotating superstructure of a locomotive or crawler crane is mounted.
boom (crane): a member hinged to the rotating superstructure and used for supporting the hoisting tackle.
booni angle: the angle above or below horizontal of the longitudinal axis of the base boom section.
boom hoist mechanism: means for supporting the boom and controlling the boom angle.
boom point: the outer extremity of the crane boom, containing the hoist sheave assembly.
boom point sheave assembly: an assembly of sheaves and pin built as an integral part of the boom point.
boom stop: a device used to limit the angle of the boom at the highest recommended position.
brake: a device used for retarding or stopping motion. cab: a housing that covers the rotating superstructure machinery or the operator’s or driver’s station.
clutch: a means for engagement or disengagement of power.
conimercial truck vehicle: a commercial motor vehicle designed primarily for the transportation of property in connection with business and industry.
counterweight: weight used to supplement the weight of the machine in providing stability for lifting working loads.
crane carrier: the undercarriage of a wheel-mounted crane specifically designed for transporting the rotating crane superstructure. It may or may not provide its own travel mechanism. It is distinguished from a commercial truck vehicle in that it is not designed to transport personnel, materials, or equipment other than the crane- rotating superstructure.
critical lift: a hoisting or lifting operation that has been determined to present an increased level of risk beyond normal lifting activities. For example, increased risk may relate to personnel injury, damage to property, interruption of plant production, delays in schedule, release of hazards to the environment, or other jobsite factors.
cross-over points: in multiple layer spooling of rope on a drum, those points of rope contact where the rope crosses the preceding rope layer.
designated person: a person selected or assigned by the employer or the employer’s representative as being competent to perform specific duties.
drum: the cylindrical member around which a rope is wound for lifting and lowering the load or boom.
dynamic (loading): loads introduced into the machine or its components due to accelerating or decelerating forces.
ensure: term used when the meaning “take steps to see that” or “make sure” is intended.
flange point: a point of contact between rope and drum flange where the rope changes layers.
gantry (A-frame): a structural frame, extending above the superstructure, to which the boom support ropes are reeved.
hoist mechanism: a hoist drum and rope reeving system used for lifting and lowering loads.
jib: an extension attached to the boom point to provide added boom length for lifting specified loads. The jib may be in line with the boom or offset to various angles in the vertical plane of the boom.
jib backstop: a device that will restrain the jib from turning over backward.
jobs ite: work area defined by the construction contract. load (zvorking): the external load in pounds (kilograms) applied to the crane, including the weight of load- attaching equipment such as lower load block, shackles, and slings.
load block, lower: the assembly of hook or shackle, swivel, sheaves, pins, and frame suspended by the hoisting ropes.
load block, upper: the assembly of shackle, swivel, sheaves, pins, and frame suspended from the boom point.
load indicator: a device that measures the weight of the load.
