ASME B30.1:2009 pdf download.Jacks, Industrial Rollers, Air Casters,and Hydraulic Gantries.

landing pads: structural spacer(s) mounted below an air caster modLile structure, which provides support while the air bladder is

deflated.

lateral: the horizontal direction perpendicular to the length of the gantry system track.

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 raz’l: movement beyond maximum travel (mechanical jack) or stroke (hydraulic jack) for which the jack was designed.

ply ‘paration: a delamination of at least two layers of rubber and/or reinforcement material.

qualified person: a person who, by possession of a recognized degree in an applicable field or certificate of professional

standing, or who, by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve or resolve

problems relating to the subject matter and work.

rated load: the maximum allowable working load established by the equipment manufacturer. The terms rated capacity and working

load limit are commonly used to describe rated load.

screw extension: a device that increases the hydraulic jack’s closed length.
