Lifts, skip hoists, escalators and moving walkways

1. Scope and Applicability

This PCR governs foreground data packages for manufacturing complete lifts (elevators), skip hoists, escalators, and moving walkways. It covers passenger, goods, or mixed-service equipment with vertical, inclined, or horizontal travel when the equipment is supplied as a functionally complete manufactured system. The product-specific bill of materials (BOM), manufacturing route, factory tests, equipment subtype, and factory-gate condition must be declared.

The common methodology ends at the manufacturing factory gate. In-house component fabrication is included when performed by the reporting manufacturer. Installation and commissioning, operation and maintenance, modernization, and dismantling or end-of-life treatment are separate conditional processes and must not be silently merged into the manufacturing dataset. If a downstream process is added, its scenario, geography, service life, duty or usage category, and energy boundary must be explicit.

The category excludes standalone lifting accessories, cranes, winches, jacks, forklift trucks, continuous-action conveyors classified outside CPC 43540, building shafts and supporting civil works, and unrelated building services. Replacement parts or isolated subsystems are excluded unless the dataset clearly declares a part or subsystem study and does not present it as a complete-equipment result.

The official lift c-PCR applies only to lifts and explicitly does not apply to skip hoists, escalators, or moving walkways. Accordingly, lift-specific rules may inform only the lift subtype. Escalator and moving-walk operational energy uses ISO 25745-3; lift operational energy uses ISO 25745-2; skip-hoist energy remains a foreground measurement or documented engineering calculation rather than an extrapolation from either standard.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	Complete factory-gate reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Report the reference output as 1 kg dry equipment mass and retain measured or BOM-reconciled whole-unit dry mass for scaling. Exclude temporary test loads, installation tools, transport packaging, and building works from equipment mass unless they are sold as part of the product.
bom_mass_basis	Materials, purchased components, internal assemblies, and product outputs	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Record net incorporated mass, input mass before losses, and waste or reject mass separately. Do not infer component shares from a generic equipment design.
energy_carrier_preservation	Manufacturing, testing, installation, and operational energy	Flow-specific energy property	kWh or MJ	Preserve the measured carrier and unit. Convert only with an explicit factor and retain the original reading, factor, converted value, and selected geography- and voltage-appropriate Tiangong energy flow.
operational_energy_boundary	Conditional use-stage energy	Flow-specific energy property	kWh per declared period	Meter or calculate only equipment-associated energy on a single-unit basis. Disclose ancillary loads and exclude them from the equipment result unless the declared scenario intentionally includes them.
lift_operational_energy	Conditional lift use stage	Flow-specific energy property	kWh/year	For lifts within the ISO 25745-2 applicability domain, use measured values, calculation, or simulation on an annual single-unit basis and disclose the chosen method and applicable lift subtype.
escalator_walk_operational_energy	Conditional escalator or moving-walk use stage	Flow-specific energy property	kWh/year	Apply ISO 25745-3 for escalators and moving walks within its declared applicability. Disclose equipment outside its stated rise or length domain and do not present the classification as directly comparable without an approved extension.
skip_hoist_operational_energy	Conditional skip-hoist use stage	Flow-specific energy property	kWh or MJ per declared duty period	Use metered foreground energy or a documented engineering calculation tied to payload, travel, cycles, standby, and auxiliaries. Do not substitute ISO 25745-2 or ISO 25745-3 default behaviour without evidence that the method is applicable.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Product-specific BOM and accepted purchased materials, components, and subassemblies at the reporting manufacturer's receiving boundary, with upstream datasets linked for their production and delivery

product_classification_scope	Complete equipment within the reviewed semantic scope; the CPC 43540 reference is mapping context and does not authorize inclusion of unrelated lifting or conveying machinery
recursive_input_rule	A purchased lift, skip hoist, escalator, moving-walk subsystem, or same-category complete unit used as an input is recorded once as a product input with an upstream dataset; its internal manufacture is not recursively expanded in the same foreground package
upstream_dataset_requirement	Each purchased material, component, energy carrier, transport service, treatment service, and other technosphere input requires a representative upstream dataset or an explicit unresolved-data disclosure
disclosure	Declare equipment subtype, complete-versus-subsystem scope, BOM coverage, outsourced and in-house operations, geography, factory-gate condition, exclusions, allocation drivers, and whether installation, use, maintenance, modernization, or end-of-life processes are present

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
alloc_subdivision_first	Shared and multifunctional manufacturing processes	Avoid allocation by metering, production-order tracking, or subdivision. If that is not possible, document why and use a causal physical driver such as machine time, energy demand, processed mass, or tested unit-hours.	eu-pef-method-2021
alloc_other_relationship_last	Residual shared burdens	Use economic or another non-physical relationship only after subdivision, system expansion, and a relevant physical relationship have been shown impracticable. Record the data period, factor calculation, affected processes, and sensitivity.	eu-pef-method-2021
alloc_internal_transfers	Internal components and intermediate equipment states	Carry internal transfers without duplicating upstream burdens. Allocate only the incremental process inputs and outputs of the receiving process.	eu-pef-method-2021
alloc_rework_and_rejects	Rework, rejects, and production scrap	Keep rework burdens with the accepted reference product. Record rejects and scrap as outputs; do not credit recycling or avoided production inside the foreground unless the chosen lifecycle method explicitly requires it and all parameters are disclosed.	eu-pef-method-2021
alloc_packaging	Equipment and packaging	Keep equipment dry mass and packaging mass separate. Allocate packaging-operation burdens using directly measured packing records or a causal driver; do not add packaging mass to the equipment reference output.	eu-pef-method-2021
