This recommended practice applies to mobile construction type cranes with cantilevered, telescopic booms when used in lifting crane service.

This document applies primarily to mobile cranes that lift loads by means of a drum and hoist line mechanism. It can be used to determine the hoist line speed and power of other hoist line mechanisms, if the load can be held constant and hoist line travel distance is sufficient for the accuracy of the line speed measurements prescribed. This recommended practice applies to all mechanical, hydraulic, and electric powered hoist mechanisms.

This SAE Standard applies to mobile, construction-type lifting cranes of the cantilever boom type (Figure 1). Questions and comments regarding application or interpretation of the provisions in this test method should be referred to the originating SAE Committee.

The scope of this SAE Recommended Practice is limited to cranes mounted on a fixed platform lifting loads from a vessel alongside. The size of the vessel is assumed not to exceed that of a work boat as defined in 3.14.

This SAE Recommended Practice applies to mobile, construction type, crane and cable excavator hand and foot controls. It should not be construed to limit the use of, or to apply to combination controls, automatic controls, or any other special operating control requirements.

This recommended practice specifies criteria for steps, stairways, ladders, walkways, platforms, handrails, handholds, guardrails and entrance openings which permit access to and from operator, inspection or maintenance platforms on mobile cranes parked in accordance with the manufacturer's instruction. It also presents requirements for guards and restraints as related to moving parts.

This SAE Standard applies to cranes when used in lifting service that are equipped with Rated Capacity Systems. Purpose The purpose of this document is to establish the minimum performance and tolerance criteria of systems used to warn or to indicate to the operator and/or other responsible persons when the load being lifted approaches, meets and exceeds the rated capacity on the applicable rated capacity chart of the crane.

The scope of this SAE Information Report is limited to a lift crane mounted on a fixed or floating platform, lifting loads from a vessel alongside. The size of the vessel is assumed not to exceed that of a workboat as defined in 3.15.
