ISO 13861-2022 pdf – Machinery for forestry — Wheeled skidders — Terms, definitions and commercial specifications.
1 Scope This document specifies terminology and required information as a general framework for identifying and describing the main dimensions and features of wheeled skidders. It is applicable to articulated wheeled cable and grapple skidders. NOTE The terminology and requirements given in this document do not necessarily all apply to a specific machine. Machines can be characterized by the dimensions and features which are relevant to them. 2 Normative references There are no normative references in this document. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminology databases for use in standardization at the following addresses: — ISO Online browsing platform: available at https:// www .iso .org/ obp — IEC Electropedia: available at https:// www .electropedia .org/ 3.1 General terms 3.1.1 skidder self-propelled machine designed to transport trees or parts of trees by trailing or dragging [SOURCE: ISO 6814:2009, 2.3.1.15] 3.1.2 ground reference plane GRP hard, flat, horizontal surface on which the machine is placed for measurements 3.2 Terms related to masses 3.2.1 normal operating mass total mass of the machine as specified, fully serviced, with full fluid levels and a 75 kg operator 3.2.2 maximum operating mass total mass of the machine as specified, fully serviced, with full fluid levels and a 75 kg operator, including all machine options with the largest tyre or hydro-inflation combination and the manufacturer’s maximum specified load
