Equipment-class discovery • Systems vary with configuration
What to identify on aerial work platforms
Personnel-platform components require the precise lifting and control configuration. Scissor, articulating and telescopic mechanisms must not share assumed service applications.
Record platform/lift identity, installed controls, power package and safety-device revisions. Request qualified inspection records for structural and safety-critical used components.
A maximum platform height does not establish interchange. No safety interlock bypass or structural substitution is supported.
Assembly identification briefs
Use these component-specific questions to prepare a precise identification record or quote request. The source references explain component families; exact values and machine applications require the correct installed assembly documentation.
Boom lift cylinders, pins and pivot bearings
Identify the aerial platform's boom configuration and the particular cylinder, pin or bearing position in the request. Preserve the machine serial and assembly references together. Used lifting components need provenance and traceable inspection evidence, with approval and acceptance requirements resolved through the manufacturer's applicable documentation before selection.

cylinder tag
Source scope: Aerial-platform OEM manual/serial-catalogue route; detailed safety circuit, turntable or lifting-component documents not acquired. This reference provides a documentation access route; topic-specific technical details have not been established.
Record platform-control, emergency-stop and interlock component identities with the aerial machine's hardware generation. Preserve connector photographs and software revisions as separate evidence. A used module or switch needs documented system application; a physical connection or a successful power-up cannot establish correct safety-system behavior.

control-board generation
certification
Source scope: Aerial-platform OEM manual/serial-catalogue route; detailed safety circuit, turntable or lifting-component documents not acquired. This reference provides a documentation access route; topic-specific technical details have not been established.
Tilt sensors, load detection and calibration systems
Identify tilt and load-detection sensors by their complete available references and the aerial platform's rated configuration. Keep calibration records associated with the machine serial. A replacement inquiry must resolve the manufacturer-defined application and commissioning requirements, leaving unsupported revisions or control relationships outside verified compatibility records.

Source scope: Aerial-platform OEM manual/serial-catalogue route; detailed safety circuit, turntable or lifting-component documents not acquired. This reference provides a documentation access route; topic-specific technical details have not been established.
Keep aerial-platform turntable, slew drive and motor identities separate while documenting their installed relationship. A used assembly should identify included gearing, bearings and brakes and disclose inspection findings. The platform model provides context but does not establish the required fastening, service limits or condition acceptance for that assembly.

Source scope: Aerial-platform OEM manual/serial-catalogue route; detailed safety circuit, turntable or lifting-component documents not acquired. This reference provides a documentation access route; topic-specific technical details have not been established.
Record the aerial platform's actual battery package and charger labels together, preserving chemistry, control and installation references as separate fields. A used power package should disclose provenance and condition evidence. Similar nominal voltage does not establish charger, battery-management or machine-control compatibility for a replacement.

voltage
charger specification
Source scope: Official example of machine-specific battery-package options; no cross-model battery, charger or control compatibility imported. The reference supports component-family context; it does not establish an individual machine application.
Identify the aerial platform's installed emergency-lowering and auxiliary-power arrangement before requesting pumps, valves or controls. Keep machine-specific circuit references with component labels. A used unit requires documented application and inspection; an apparent ability to move a cylinder does not establish correct operation of the emergency system.

Start with the manufacturer, model suffix and installed equipment. The following specialist subjects help describe a sourcing request; they do not identify a specific orderable part.
Lift cylinders
Record the installed assembly identification, its position and configuration. Ask the supplier which documentation connects the proposed replacement to that assembly.
platform controls
Record the installed assembly identification, its position and configuration. Ask the supplier which documentation connects the proposed replacement to that assembly.
slew drives
Record the installed assembly identification, its position and configuration. Ask the supplier which documentation connects the proposed replacement to that assembly.
safety interlocks
Record the installed assembly identification, its position and configuration. Ask the supplier which documentation connects the proposed replacement to that assembly.
For a used or rebuilt component, ask for its donor-unit provenance, inspection record, repair scope and any remaining identification marks. A donor model is context, not proof of fitment to another machine.
Aerial-platform structure, power and safety-control boundaries
JLG identifies the 600AJ as an articulating boom lift with a defined platform and optional equipment. That is a scoped architecture example. Scissor, telescopic and articulating machines cannot be treated as one interchangeable cylinder, control or emergency-power system.
Architecture and assembly boundaries
Separate carrier travel, upper-structure rotation, boom articulation and platform functions. Each cylinder and pivot occupies a defined structural position. The turntable bearing and slew drive connect another pair of assemblies. Platform and ground controls communicate through a configuration-dependent electrical system, while emergency lowering or auxiliary power has a separate role. A replacement control box must not be described as a complete safety system merely because it contains an emergency-stop button.
Variants that change the research path
Boom geometry, jib, platform option and power source can change mechanical and electrical interfaces. Battery chemistry, nominal voltage and charger design require exact evidence on electric equipment. Tilt and load sensing need the applicable controller and calibration context. A board with the same connector or enclosure is not automatically compatible. Regional standards and machine-generation changes must be preserved, particularly where software, alarms or interlocks depend on the complete installed configuration.
Condition evidence and selection record
Record structural damage, pivot movement, damaged harnesses and unreadable sensor or control identifiers as conditions for qualified evaluation. Do not use a functioning control or movement demonstration to certify an interlock or lifting structure. Used cylinders, booms and controllers need traceable identity and inspection/test evidence. Leave capacity, sensor calibration, emergency-circuit settings and acceptance limits blank until exact manufacturer documents support them. These six workpacks are research boundaries and supply no bypass, adjustment, rescue or high-risk maintenance procedure.
Specification evidence record
Published values retain their exact reference scope. Empty fields mean the value has not been established; they never mean zero. General model associations do not establish installed or serial-specific fitment.
