Equipment-class discovery • Systems vary with configuration
What to identify on cranes
Identify crane configuration, boom system, hoist and safety controls as a documented lifting installation. Carrier components are separate from lifting-assembly components.
Retain boom sections, rope/block arrangement, counterweights and outrigger configuration with serial-matched records. Request traceability and inspection evidence for offered hoist and structural items.
No lifting rating or safety-critical replacement is approved by a model match. Missing certification or qualified review remains a hold.
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.
Hoist drums, winches and hydraulic motors
A crane hoist inquiry should identify the particular winch, motor and brake package within the rated crane configuration. Preserve labels and the machine serial record together. Ask a rebuilt supplier for traceable inspection and test documentation; a general lifting-capacity description cannot establish a specific hoist assembly's suitability.

rated hoist configuration
drum model
certified components
Source scope: Crane-OEM manuals, inspection, structural-repair and remanufacturing support routes; not the serial-specific crane's repair or load instructions. This reference provides a documentation access route; topic-specific technical details have not been established.
Keep wire-rope, sheave and hook-block identities and inspection records together for a crane inquiry. Record the documented reeving configuration and available certification without assuming that one hook block suits another crane. A used rope or block needs assessment under its applicable manufacturer documentation by a qualified person before acceptance.

inspection code
Source scope: Official model-specific example showing identification and inspection-record dependencies; not applicable inspection criteria for every crane. The reference supports component-family context; it does not establish an individual machine application.
Identify crane boom-extension slides and wear pads by section, position and boom revision. Preserve photographs showing their original locations and request the applicable parts drawing. Used sections or pad carriers need documented inspection; dimensions or exterior condition alone cannot establish structural acceptance, adjustment requirements or a complete extension package.

Keep a crane's slew-ring bearing and swing-drive references distinct, including their installed mounting context. Ask a used-component supplier for inspection findings, provenance and the exact pieces included. Bearing fastening requirements and permissible condition must come from the crane's applicable documentation rather than a generic bearing description.

Identify each crane outrigger and jack assembly within the machine's documented support arrangement. Include mounting position, component identification and any recorded structural repairs. A used pad or jack should have traceable condition evidence; matching appearance does not establish load approval or the support settings required by the crane.

Load-monitoring electronics, interlocks and sensors
A crane load-monitoring inquiry needs controller and sensor revisions together with the crane's rated configuration. Keep software and calibration records associated with that serial number. A replacement electronics offer must resolve these dependencies through the OEM support channel before its compatibility can be represented as verified.

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.
Hoist
Record the installed assembly identification, its position and configuration. Ask the supplier which documentation connects the proposed replacement to that assembly.
boom systems
Record the installed assembly identification, its position and configuration. Ask the supplier which documentation connects the proposed replacement to that assembly.
rope assemblies
Record the installed assembly identification, its position and configuration. Ask the supplier which documentation connects the proposed replacement to that assembly.
rated load control
Record the installed assembly identification, its position and configuration. Ask the supplier which documentation connects the proposed replacement to that assembly.
outriggers
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.
Crane hoisting systems and configuration-controlled components
Liebherr describes a telescopic boom, lattice-jib options and support/counterweight technologies for the LTM 1230-5.1. These are scoped configurations. They demonstrate why a crane component inquiry needs its rated arrangement, not only the crane model or maximum advertised capacity.
Architecture and assembly boundaries
Distinguish the carrier, rotating upper structure, boom equipment and hoist system. A hoist motor and drum do not by themselves describe the rope, sheaves, hook block and reeving arrangement that carry the load. The slew bearing and swing drive form another interface between upper structure and carrier. Outrigger jacks transfer loads through their own mounting and support configuration. A complete component record should state whether associated brakes, controls, lines and connection hardware are included.
Variants that change the research path
Telescopic and lattice configurations require different structural and connection evidence. Additional hoists, jib arrangements, counterweight packages and support positions can alter the applicable rated configuration. Similar sheave diameter does not establish rope compatibility or an approved block assembly. Load-monitoring electronics are also configuration controlled: sensors, software and calibration belong to the rated system. Category-level examples cannot approve a replacement controller or infer that a component from a neighbouring crane model is suitable.
Condition evidence and selection record
For used or rebuilt equipment, seek traceable identity, inspection records and the exact supplied scope. Photographs can reveal markings, deformation, damage or corrosion, but cannot certify a lifting component or establish rope discard criteria. Record observations for qualified review and refer inspection/acceptance decisions to the applicable manufacturer documentation. Keep line specification, reeving, brake rating, bearing fastening requirements and controller configuration unresolved until supported. None of the six workpack topics is a substitute for a lifting-equipment inspection or a rated load chart.
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.
