SECTION 1-0.2: DEFINITiONS
air bladder (air caster): a monofiLm or fabric-reinforced material enclosure that directs air flow beneath the air caster’s module structure.
air caster: a device that can provide lift and travel of a load using air flow as the support medium, often referred to as air skates or air bearings.
air caster, gap crossing: a fabricated module that contains a load support plate, a landing pad, and a perforated air bladder that provides the ability to travel across gaps and steps in the operating surface.
air caster, high lift: a fabricated module that contains a load support plate, a landing pad, and an air bladder that provides approximately twice the effective lift height of a low-lift air caster and inflates without requiring contact with the operating surface for inflation.
air cash’r, low lft: a fabricated module that contains a load support plate, a landing pad, and an air bladder that provides approximately half the effective lift height of a high-lift air caster and requires contact with the operating surface for inflation.
air caster system: consists of air suppl air hoses, pressure control console, and air casters.
air-lifting bag: a reinforced, flat, rubberized single-chamber inflatable bag designed to contain air at pressures above 100 psi.
air-lifting bag system: consists of air supply, air hoses, pressure control unit, and air-lifting bag.
authorized service center: an independent service facility designated by the manufacturer to repair arid test equipment of their manufacture.
hirdcaging: the permanent deformation of a section of strand in which the wires spread apart.
drift: horizontal displacement of the top of a telescopic lift boom that results from clearances between boom sections.
industrial roller: a structural frame containing interlinked rollers or wheels designed to support and transport a load, often referred to as skates or dollies.
jack: a portable hand or a 1xnver-opera ted mechanism with a base and a load point designed for controlled linear movement.
jack, doubk-acting hydraulic: a jack that is extended and retracted under hydraulic pressure.
jack, hydraulic: a jack using liquid to move the load. jack, mechanical: a jack using any means other than fluid to move the load.
jack, self-contained: a hydraulic jack whose hydraulic reservoir and pump are contained within the jack’s housing.
jack. single-acting hydraulic: a jack that is extended under hydraulic pressure and retracted by release of the hydraulic pressure.
landing pads: structural spacer(s) mounted below an air caster module structure, which provides support while the air bladder is deflated.
lateral: the horizontal direction perpendicular to the length of the gantry system track.
LHE (load handling equipment): all equipment covered by
ASME B30.1.
load: the total superimposed weight or force to be overcome by the load handling equipment.
load point: the point of load application.
load point, auxiliary: any point of load application other than the load point.
load point, integral auxiliary: any nonremovable point of load application other than the load point.
longitudinal: the horizontal direction parallel to the length of the gantry system track.
module structure (air caster): the load support platform that interfaces between the load and the air bladder. overload: any load greater than the rated load. overt ravel: movement beyond maximum travel (mechanical jack) or stroke (hydraulic jack) for which the jack was designed.
ply separation: a delamination of at least two layers of rubber and/or reinforcement material.ASME B30.1 pdf download.
