Transmodel is composed of 10 parts (see above). This work item consists in the revision and update of the documentation of the Public transport reference data model – Part 8 (Transmodel – Part 8). The update consists basically of the following types of actions: a. Simplication of Part 8 based on the revision of Part 1: several functional extensions of Transmodel took place since the last publication of EN12896 (in 2016 and 2019). The functional extensions elaborated until 2019 generated additional common concepts which have already been published in the relevant documents. These additional common concepts are now integrated into Transmodel - Part 1 and thus removed from Part 8. b. Updates/extensions of Part 8 as a consequence of • Work presented in TR17370:2019. This TR provides a list of KPIs calculated using operational raw data. The action consists here to provide data model extracts, representing the raw data needed for several KPIs (listed in TR17370:2019), The extracted sub-models are based upon the (already existing) "Loggable object model" and will complete the 2 examples published in the current version of Part 8. c. Ensuring coherence of the Transmodel eco-system.

This document is applicable to the design, information for use, maintenance and testing of power-driven winches for which the prime mover is an electric motor, hydraulic motor, or pneumatic motor. Winches are designed for the movement or manipulation of loads supported on level or inclined planes in situations where risks resulting from a failure of the winding mechanism or pulling medium are mitigated by external measures. This document is not applicable to devices which handle suspended loads. Generally, a winch is used without any additional transport movement, except in cases where a winch is used on a stranded vehicle for self-recovery of the vehicle. Applications of winches covered are for example, but not limited to: a) rope winches; b) belt winches, except steel belts used as pulling media; c) traction winches, including double capstan and traction sheave winches. These types of winches a) to c) also include the following specific applications: — vehicle recovery winches; — winches for boat trailers; — winches for stationary offshore applications. NOTE Examples are shown in Annex H. This document does not apply to: — power-driven hoists in accordance with EN 14492-2; — forestry winches in accordance with EN ISO 19472-1; — winches for seagoing vessels and mobile offshore units; — winches for the lifting of persons; — NGL building hoists in accordance with EN 14492-2; — winches for the handling of hot molten masses.
