ASME B30.17:2003 pdf download.OVERHEAD AND GANTRY CRANES.
crane, outdoor: an overhead or gantry crane that operates outdoors and for which provisions are not available for storage in an area that provides protection to the crane from weather conditions. An indoor crane that may operate outdoors on a periodic basis is not classified as an outdoor crane.
crane, overhead: a crane with a movable bridge carrying a movable or fixed hoisting mechanism and traveling on an overhead, fixed runway structure (refer to Figs. 1 and 3 for the types covered by this volume).
crane, wer-operated: a crane whose mechanism is
driven by electric, pneumatic, hydraulic, or internal combustion means.
crane, pulpit-operated: a crane whose movements are controlled by an operator through the use of controllers located in a contrul room, a fixed or movable cab, or a platform that is independent of the crane.
crane, remote-operated: a crane whose movements are controlled by an operator through the use of controllers contained in a portable operating station not attached to the crane
crane, sernigantry: a gantry crane with one end of the bridge rigidly supported on one or more legs that run on a fixed rail or runway, the other end of the bridge being supported by an end truck running on an elevated rail or runway (refer to Fig. 5).
crane service, normal: service that involves operation with randomly distributed loads within the rated load limit, or with uniform loads of less than 65% of the rated load, for no more than 15% of the time of a single work shift for manually operated cranes and 25% of the time of a single work shift for electrically pneumatically powered cranes.
crane service, heaz’y: service that involves operation within the rated load limit that exceeds normal service.
crane service, severe: service that involves normal or heavy service with abnormal operating conditions.
crane, standti: a crane that is not in regular service but is used occasionally or intermittently as required.
crane, overhead: a crane with a movable bridge carrying a movable or fixed hoisting mechanism and traveling on an overhead, fixed runway structure (refer to Figs. 1 and 3 for the types covered by this volume).
crane, wer-operated: a crane whose mechanism is
driven by electric, pneumatic, hydraulic, or internal combustion means.
crane, pulpit-operated: a crane whose movements are controlled by an operator through the use of controllers located in a contrul room, a fixed or movable cab, or a platform that is independent of the crane.
crane, remote-operated: a crane whose movements are controlled by an operator through the use of controllers contained in a portable operating station not attached to the crane
crane, sernigantry: a gantry crane with one end of the bridge rigidly supported on one or more legs that run on a fixed rail or runway, the other end of the bridge being supported by an end truck running on an elevated rail or runway (refer to Fig. 5).
crane service, normal: service that involves operation with randomly distributed loads within the rated load limit, or with uniform loads of less than 65% of the rated load, for no more than 15% of the time of a single work shift for manually operated cranes and 25% of the time of a single work shift for electrically pneumatically powered cranes.
crane service, heaz’y: service that involves operation within the rated load limit that exceeds normal service.
crane service, severe: service that involves normal or heavy service with abnormal operating conditions.
crane, standti: a crane that is not in regular service but is used occasionally or intermittently as required.
