radius (load): the horizontal distance from a projection of the axis of rotation to the base of the crane, before loading, to the center of the vertical hoist line or tackle with load applied.
rail clamp: a device for fastening a traveling crane to its rails to limit wind-induced travel.
rated load (load rating): the maximum allowable working load designated by the manufacturer; rated loads are expressed in pounds, kilograms, short tons, or metric tons.
reconfigure: the addition or deletion of jib, luffing boom, or counterjib sections while the crane is erected.
remote control: a radio or cable control device used to activate the crane control functions.
rope: refers to wire rope unless otherwise specified. rotation-resistant rope: wire rope consisting of an inner layer of strands laid in one direction, covered by a layer of strands laid in the opposite direction; this has the effect of counteracting torque by reducing the tendency of the finished rope to rotate.
running ropes: rope that spools on/off drums. shall: this word indicates that the rule is mandatory and must be followed.
sheave: a grooved wheel or pulley used with a rope to change the direction and point of application of a pulling force.
should: this word indicates that the rule is a recommendation, the advisability of which depends on the facts in each situation.
slewing moment: moment acting in a horizontal plane about the centerline of rotation, induced by the slewing and brake mechanisms of the crane.
structural competence: the ability of the machine and its components to withstand imposed stresses.
superstructure: that portion of the crane that rotates. swing (slew): rotation of the superstructure for movement of loads in a horizontal direction about the axis of rotation.
tie-in: a structural support consisting of a collar that surrounds the tower that utilizes bracing to attach to the host structure.
tower: a vertical structural frame consisting of columns and bracing capable of supporting a superstructure with its working and dynamic loads and transmitting them to the supporting surface or structure.
trolley (load): the component of the crane that moves along the jib of a hammerhead tower crane and positions the load radially.
ii;iattended: a condition in which the operator of a crane is not at the operating controls.
weafhervaniizg: releasing of the swing brakes to allow wind-induced rotation of a crane superstructure, when out-of-service, to expose minimal surface area to the wind.
wedge: a tapered device used to provide stability.
