Evaluating BendPak Lift Cables: Compatibility, Specs, and Sourcing
Replacement cable selection for BendPak vehicle lifts requires matching mechanical specifications, termination styles, and service history to maintain safe operation. This discussion covers common BendPak lift families and the cable constructions they use, how to identify the correct part numbers and measurable specifications, differences between OEM and aftermarket cable assemblies, practical installation and safety checks, inspection signs that indicate replacement, and sourcing and warranty considerations relevant to procurement decisions.
Common BendPak lift models and cable types
Many BendPak installations fall into recognizable categories: two-post symmetric and asymmetric lifts, four-post lifts, and scissor lifts. Each category tends to use different cable architectures. Two-post designs usually rely on multiple steel wire ropes routed over sheaves and anchored at the carriage. Four-post lifts commonly use fewer, longer run cables or chain-sprocket systems. Scissor lifts may use shorter cables with bespoke terminations integrated into linkages.
| Model family | Common cable construction | Typical termination | Notes |
|---|---|---|---|
| Two-post (general) | Galvanized steel 6×19 or 7×19 | Swaged eye, threaded stud | Multiple parallel runs; keep equal lengths and routing |
| Four-post (drive-on) | Heavier diameter 6×37 or similar | Pin or clevis, end ferrule | Longer spans; inspect for stretch and corrosion |
| Scissor lifts | Compact multi-strand ropes or custom assemblies | Custom fittings to linkage | Often model-specific; replacements may be OEM-only |
Identifying correct part numbers and specifications
Start at the equipment nameplate and parts manual. The serial number and model code on the lift are the primary keys for identifying factory part numbers. Parts diagrams and exploded views list cable assembly PN, termination PN, and related hardware such as thimbles, ferrules, and clips. If a parts manual is not available, measure the cable directly: overall length under tension, outer diameter, strand count (for example, 7×19 means seven strands of 19 wires), core type, and the exact shape of the end fittings.
Specifications to record include nominal cable diameter (in inches or mm), rated breaking strength or minimum breaking load if available, whether the cable is galvanized or stainless, and termination detail (swage, threaded socket, rolled eye). These measurable attributes are essential when cross-referencing aftermarket suppliers or confirming OEM replacement compatibility.
OEM versus aftermarket cable comparisons
OEM assemblies are produced to match factory drawings and often include traceability to material certificates and swage/termination processes used in original manufacturing. Aftermarket cables can be cost-competitive and may offer faster lead times, but traceability varies. When comparing options, prioritize vendors that provide dimensional drawings, material specifications (wire grade, galvanizing), and swage or crimp-process verification.
Third-party test data—such as tensile test reports or fatigue testing summaries—can help validate aftermarket quality. Observe that aftermarket suppliers sometimes substitute compatible terminations; compatibility should be confirmed by comparing the measured termination geometry and any mating hardware. For older lifts where OEM parts are obsolete, certified aftermarket assemblies with documented testing are a pragmatic option.
Installation and safety considerations
Proper installation affects both performance and safety. Routing must reproduce factory cable paths, maintain correct sheave contact, and avoid sharp bend radii that accelerate fatigue. Replace sheaves, bearings, and fasteners if they show wear; a worn pulley will cut service life of new cables. Use the correct swage tooling or factory-specified fittings—improper swaging or using mismatched clips can reduce rated capacity.
Hydraulic and mechanical alignments should be verified before returning a lift to service. Load-test procedures vary by jurisdiction and shop practice, but functional load checks to rated capacity and balance testing between columns are standard practices. Because lift cables are safety-critical, installation by qualified technicians familiar with vehicle lift service norms is the accepted standard.
Inspection, lifespan, and maintenance indicators
Routine inspections focus on broken wires, corrosion, diameter reduction, kinks, and visible core damage. A single broken wire may not require immediate replacement, but multiple adjacent broken wires, necking (localized diameter loss), or wire unraveling are clear replacement triggers. Corrosion that compromises surface wires or end fittings is another criterion for replacement.
Typical service life depends on frequency of cycles, environment (salt, humidity), load profiles, and preventive maintenance. Shops that log service hours and track cable condition tend to replace assemblies proactively before visible failure. Lubrication practices, correct tensioning, and addressing sheave wear all extend useful life.
Replacement trade-offs and service constraints
Cost versus traceability is the most common trade-off: OEM parts usually offer direct traceability to factory specifications but can have longer lead times and higher cost. Aftermarket options may be cost-effective and faster, but some vendors lack complete test documentation. Accessibility is another constraint—older lifts or installations in confined pits can make field replacement complex and require specialized hoisting and personnel. Shops without certified tooling for swaging or testing should factor the cost of tools or outsourced installation into the procurement decision.
Model-specific variations sometimes mandate OEM-only components. When aftermarket technical data is limited, rely on measurable attributes and third-party test reports. Where warranties are a factor, note that manufacturer warranty terms frequently specify use of OEM parts and authorized service for coverage continuity.

Matching the right cable assembly combines documentary verification and measured confirmation. Use the lift’s model and serial number to locate OEM part numbers, then confirm dimensions, termination types, and material grades before procurement. Consider supplier traceability and test data when weighing aftermarket options, and ensure installation and load-testing are performed by technicians with appropriate tools and procedures. These steps reduce uncertainty and support reliable sourcing and service planning for fleet and shop operations.
