ASME B30.3:2016 pdf free download.Tower Cranes.
ballast: weight added to a crane base to create additional stability; it does not rotate when the crane swings.
base, anchor bolt: a crane base that is bolted to a footing (see Fig. 3-0.2.2-I, illustration (a)].
base, expendable: for static-mounted cranes, a style of bottom tower section or member that is cast into a concrete footing block; all or part of this component is lost to future installations Isee Fig. 3-0.2.2-I, illustrations (a) and (b)1.
base, fixed ballasted: a crane base that is a ballasted platform that does not travel.
base, knee-braced: a crane base that uses diagonal members to spread the loading (see Fig. 3-0.2.2-1, illustration (c)].
base tiiwer: a mounting accessory to secure the bottom of the tower to a foundation, structural support, travel, or hallasted base.
base, traveling: a crane base that is a ballasted platform mounted on bogies that ride along rails (see Fig. 3-0.2.1.4-1)
bogk: an assembly of two or more axles arranged to permit both vertical wheel displacement and an equalization of loading on the irheek.
brace, tower: a structural attachment placed between a crane tower and an adjacent structure to pass loads to the adjacent structure and permit the crane to be erected to greater than freestanding height (see Fig. 3-0.2.1.3-1).
brake: a device, other than a motor, used for retarding or stopping motion by friction or power means.
braking means: a method or device for retarding or stopping motion.
buffrr: an energy-absorbing device for reducing impact when a moving crane or trolley reaches the end of its permitted travel.
cab: a housing provided for the operator and containing the crane controls.
climbin’’: for freestanding, braced, or guyed cranes, the process whereby the height of the tower is increased by adding sections at the top (see Fig. 3-0.2.1.3-1); for internal climbing cranes, the process whereby the entire crane is raised or lowered on or within a structure which is under construction (see Fig. 3-0.2.1.3-2).
climbñrg cross-member: a structural member attached to the end of the hydraulic cylinder used to engage the climbing ladders or lugs via pawls to raise or lower the crane structure.
climbing frame: for freestanding, braced, or guyed cranes, a structural frame supporting the superstructure which surrounds the tower and contains arrangements to raise the frame and superstructure of the crane for insertion.
