신형 오버헤드 크레인과 중고 오버헤드 크레인: 비용, 안전성 및 수명 주기 비교

In crane procurement, “new” and “used” cranes are not just a matter of age—they are fundamentally different solutions in terms of technical condition, risk, and management. Their suitability depends on how well the equipment matches the application, not on the equipment itself.

The main advantage of used cranes is cost. With similar specifications, used cranes are typically 40%–60% cheaper than new ones, making them attractive for projects with tight budgets or short timelines. However, they often fall short in technical transparency, remaining service life, operational predictability, and after-sales support, requiring more careful inspection and maintenance.

From an engineering and operational perspective, this article compares new and used cranes across four dimensions: budget, safety and technical requirements, service life, and after-sales support, providing guidance for different types of projects and enterprises.

Quick Comparison: New vs Used Overhead Crane

Cost: Upfront Price and Long-term Cost

To illustrate how the operating costs of new and used cranes play out in practice, we present two project examples: one for a long-term, multi-year project, and another for a short-term, temporary project. Each example shows the total cost and helps determine which option is better suited to different project needs.

프로젝트 배경: LD Single girder overhead crane, 10 t capacity, 7.5 m span, 9 m lifting height, medium-duty workshop.

Cost Example: Long-Term Project (8 years)

결론: The used crane is much cheaper upfront (~56%), but over 8 years total cost is similar due to higher maintenance and component replacement. Suitable for projects with flexible timelines and maintenance capability.

Cost Example: Short-Term Project (3 years)

결론: For short-term use, the used crane offers significant savings (~22%). Best for temporary or low-duty applications.

Safety & Technical Condition

New overhead crane offers a high level of technical transparency. The crane is designed based on a defined duty class and working cycle, with fatigue life calculations already completed at the design stage. Structural components such as girders, end trucks, and welded joints start their service life from zero. Hoisting mechanisms, brakes, and safety devices are factory-tested before delivery, so their performance limits and operating conditions are clearly known.

Used overhead crane is not necessarily unsafe, but its main challenge lies in the uncertainty of past usage. The actual loads handled, lifting frequency, impact conditions, and maintenance quality over its previous service life cannot be fully reconstructed, even with inspection and testing. As a result, safety evaluation relies more heavily on inspection depth, engineering judgment, and the buyer’s ability to manage uncertainty.

From a practical engineering perspective:

• For low-risk applications, where loads are stable and the company has proper inspection, monitoring, and maintenance procedures in place, the safety risks of a used crane can be effectively managed.
• For safety-critical or continuous-production applications, such as heavy-duty handling or processes where downtime and accidents carry high consequences, buyers usually prefer a new crane due to its clearer technical condition and lower uncertainty.

Lifecycle: Design Life vs Remaining Life

The service life of an overhead crane is a key factor in procurement decisions, especially when comparing new and used equipment. The main difference lies not in whether the crane can operate, but in how much usable life remains.

New overhead crane is delivered with its full design service life available. Under normal operating conditions and proper maintenance, a typical overhead crane is designed to operate for 15–20 years or more, depending on duty class and usage frequency. This makes new cranes suitable for long-term projects, permanent facilities, and operations with stable or increasing production demand.

Used overhead crane, by contrast, has already consumed part of its service life. Even if the crane is still in good working condition, its remaining usable life is shorter, and this remaining life depends heavily on how it was previously used, maintained, and loaded. For example, a crane previously operated in high-duty or multi-shift conditions may have significantly less remaining life than one used intermittently.

Maintenance & Support: Service, Spare Parts, and Support

New cranes typically come with a complete manufacturer support system, including equipment drawings, technical specifications, spare parts lists, and standardized maintenance procedures. Key components such as motors, gearboxes, brakes, and control systems have clear model classifications, with well-defined paths for maintenance, upgrades, and technical support.

The after-sales capability of used cranes largely depends on their source and manufacturing age. Some equipment may face difficulties in obtaining spare parts or technical support if models are discontinued, systems have been modified multiple times, or non-standard configurations are used. Any failure of critical components can result in unpredictable downtime, directly affecting production continuity.

Conclusions:

• High demands for operational continuity and quick response → New cranes offer greater assurance
• Mature in-house maintenance capabilities and spare parts channels → Used cranes may be acceptable

Selection Summary: How to Make the Right Choice

From an engineering perspective, the choice between new and used cranes essentially reflects usage strategy and risk preference:

• Used cranes are suitable for applications with limited budgets, defined service periods, and controllable risks.
• New cranes are better suited for long-term operation, high safety requirements, and critical production tasks.

A rational crane procurement decision should be based on a comprehensive assessment of operating conditions, workload, safety requirements, and maintenance capabilities—not on price alone. Only when the equipment is closely matched to the application can a crane continue to deliver value throughout its lifecycle.
