Equipment-class discovery • Systems vary with configuration
What to identify on telehandlers
Boom extension, wear pads, stabilization and load-control equipment need configuration-specific documentation. The attachment and the carrier have separate identities.
Record boom assembly, extension-stage position, installed load-control system and stabilizer package. Preserve fork carriage or work-tool identity and applicable documentation.
Rated capacity or maximum reach is not a replacement specification. Load-path and safety-control components require qualified review.
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.
Telescopic boom wear pads and slide components
Map telehandler boom wear pads to their actual section and position before comparing replacements. Preserve the boom and machine identities and any known repair history. For used slides or pad carriers, request an inspection record; approximate pad dimensions do not establish material, adjustment requirements or suitability for the rated boom.

Identify the telehandler's boom-extension arrangement and the fitted cylinder, chain or tension assembly separately. Keep section layout and available identifiers with the inquiry. A salvaged extension package needs traceable provenance and condition evidence; the machine's marketing reach cannot establish the components or settings required for its extension system.

Record the telehandler carriage and attachment plate identities alongside the fork markings and stated ratings. Keep the locking arrangement visible in photographs and ask whether the offer includes retention hardware. A familiar interface or similar fork length does not establish the attachment's approved use with the machine's load configuration.

Identify an outrigger cylinder or pad by its actual leg position and machine support configuration. Include the serial-specific arrangement and any component label in the request. Used support assemblies need documented condition and OEM acceptance for the intended application; their appearance cannot establish the machine's permitted lifting configuration.

Axle drive, four-wheel steering and differential parts
Keep each telehandler axle tag and steering configuration with the drive-component inquiry. A replacement may need to match steering function as well as mechanical drive interfaces. Ask a rebuilt-axle seller to specify supplied steering and brake equipment, with test records attached to the identified assembly.

Source scope: Cat drivetrain families and rebuild-reference resources; no serial-specific internal configuration reviewed. The reference supports component-family context; it does not establish an individual machine application.
Record the load-indicator sensor and control-module identifiers, available revisions and the telehandler's rated configuration. A used electronic unit needs provenance and a documented compatibility assessment before selection. Treat calibration requirements and approved software as unresolved technical details until the machine manufacturer or authorized service channel supplies the applicable documentation.

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.
Boom wear pads
Record the installed assembly identification, its position and configuration. Ask the supplier which documentation connects the proposed replacement to that assembly.
extension cylinders
Record the installed assembly identification, its position and configuration. Ask the supplier which documentation connects the proposed replacement to that assembly.
stabilizers
Record the installed assembly identification, its position and configuration. Ask the supplier which documentation connects the proposed replacement to that assembly.
load sensing
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.
Telehandler boom, carriage and rated-configuration research
JLG explains telehandler capacity through a chart tied to boom position and the attachment. This establishes a configuration boundary: a fork carriage, boom component or control device cannot be approved from a headline lift-capacity number without the applicable arrangement.
Architecture and assembly boundaries
The telescopic boom contains sliding interfaces, extension elements and load-carrying structure. Wear pads support section alignment, while extension cylinders, chains or other mechanisms move the sections according to the fitted design. The carriage and forks introduce another rated interface at the boom end. Axles and steering hardware provide carrier movement, and stabilizers add support where fitted. Research each assembly independently before connecting it to the machine-level load information.
Variants that change the research path
Boom-section count, extension design and attachment interface can change within a telehandler family. A physically similar wear pad may occupy a different position or use a different retention arrangement. Fork dimensions alone do not identify their rating or carriage class. Steering options likewise require the actual axle and control configuration. Load-moment sensors and controllers need the applicable calibration and machine build; apparent electrical connectivity is not evidence that a replacement preserves the rated system.
Condition evidence and selection record
Record wear-pad location, section identity, visible retention details and the fitted attachment. Document damage, abnormal movement or unreadable markings for qualified evaluation rather than supplying a generic wear limit. A used boom assembly needs provenance and a clear inclusion list, not just a claim that it lifts. Leave extension stroke, chain specification, fork rating and sensor calibration fields blank until their exact records are obtained. The load chart remains the authority for the installed lifting configuration, not an interchangeable-parts list.
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.
