You draw up a maintenance plan for a crane system by creating an overview of all components to be inspected, determining inspection frequencies based on usage and load, and clearly assigning responsibilities. A good plan combines preventive inspections, statutory certifications, and corrective actions in one structured document that aligns with business operations.
For industrial companies that work with cranes on a daily basis, a maintenance plan is not a luxury but an obligation. Both the safety of employees and the continuity of production processes depend on it. In this article, we answer the most frequently asked questions about drawing up a crane maintenance plan.
What should a maintenance plan for a crane include?
A complete maintenance plan for a crane system contains at minimum a description of the system, an inspection and maintenance schedule, an overview of critical components, a record of completed work, and a list of responsible persons. The plan must be specifically tailored to the type of crane, the lifting capacity, and the intensity of use.
In concrete terms, this means the plan contains the following elements:
- System description: type of crane, year of construction, lifting capacity, and location
- Maintenance schedule: daily, monthly, annual, and multi-year tasks
- Critical components: which components require extra attention
- Registration log: date, work performed, and findings
- Responsibilities: who performs what and who bears final responsibility
- Emergency procedures: what to do in the event of a malfunction or unsafe situation
A good maintenance plan is not a static document. It evolves alongside the crane and its usage. Every inspection yields new information that further refines and improves the plan.
How often should a crane system be inspected?
A crane system must be certified at least once a year by an accredited inspection body, as legally required in the Netherlands. In addition, periodic checks are necessary: daily visual checks by the operator, monthly technical inspections, and semi-annual thorough inspections of mechanical and electrical components.
The exact frequency depends on several factors:
- Intensity of use: a crane that runs multiple shifts per day requires more frequent maintenance than a crane that is used occasionally
- Load class: cranes that structurally operate close to their maximum lifting capacity wear out faster
- Environmental factors: dust, moisture, temperature fluctuations, and chemical substances accelerate wear
- Age of the system: older cranes generally require more attention than newer installations
The annual statutory certification is a minimum. For intensively used systems in heavy industry, a higher inspection frequency is strongly recommended.
What is the difference between preventive and corrective maintenance?
Preventive maintenance on a crane is planned maintenance carried out before a malfunction occurs, with the aim of slowing wear and preventing breakdowns. Corrective maintenance is reactive: it is carried out after a component has failed or a malfunction has been identified. Preventive maintenance is almost always cheaper and safer.
Preventive maintenance
With preventive maintenance on a crane system, components are replaced or overhauled based on operating hours, calendar periods, or wear indicators, before they actually fail. Think of lubricating running wheels, checking brake linings, and inspecting cable drums. This type of maintenance is plannable and fits within a structured maintenance plan.
Corrective maintenance
Corrective maintenance comes into play when a crane has already broken down or shows a defect. Although this is sometimes unavoidable, it brings unexpected downtime, which in production environments directly leads to loss of capacity and revenue. A good preventive maintenance plan significantly minimizes the need for corrective intervention.
Which parts of a crane require the most attention?
The components of a crane system that require the most maintenance attention are the hoist motor, the brakes, the running wheels, the steel cables or chains, the electrical installation, and the supporting structure. These are the components that bear the greatest mechanical load and where wear occurs most rapidly.
A closer look at each component:
- Hoist motor and gearbox: regular lubrication and monitoring for overheating are essential
- Brakes: brake linings wear with intensive use and must be periodically measured and replaced
- Steel cables and chains: check for wire breaks, deformation, and corrosion; replace in a timely manner
- Running wheels and rails: wear on wheels and rails leads to irregular travel behavior and additional load on the structure
- Electrical installation: cable drag systems, sockets, and control systems require regular inspection for insulation damage and connections
- Supporting structure: check for cracking, deformation, and corrosion, particularly at weld joints
For older crane systems or systems in harsh environments, it is advisable to inspect these components more frequently than the minimum schedule prescribes.
Who is responsible for crane maintenance within a company?
Final responsibility for the maintenance of a crane system lies with the employer or the owner of the installation. In practice, this responsibility is divided between a technical manager or maintenance department within the company, combined with an accredited external inspection and maintenance company for the legally required certifications.
A clear division of tasks prevents ambiguity and ensures nothing is overlooked:
- Crane operator: daily visual check before use and reporting of anomalies
- Technical manager or maintenance department: periodic internal inspections and maintaining the maintenance log
- External inspector or maintenance company: annual certification, thorough technical inspections, and specialist maintenance
- Management or safety coordinator: final responsibility for compliance with laws and regulations and making budget available
Record this division in writing in the maintenance plan. This way, in the event of an incident, it is always demonstrable who bore which responsibility.
When is it time to have a crane system overhauled?
A crane system is due for overhaul when recurring malfunctions occur regularly, the costs of corrective maintenance are structurally increasing, critical components have reached the end of their technical service life, or the crane no longer meets current safety and production requirements. A thorough overhaul is then more cost-effective than continuing to repair.
Concrete signals indicating the need for overhaul:
- Increasing frequency of malfunctions despite regular preventive maintenance
- Significant wear on the supporting structure, running wheels, or drive system
- Outdated electrical installation that no longer meets current standards
- Changed production requirements for which the current crane is no longer suitable
- A negative outcome of the annual certification with a recommendation for overhaul
Overhaul does not automatically mean replacement. In many cases, an existing crane system can be fully overhauled and technically modernized, which is considerably more cost-efficient than purchasing a completely new system.

Frequently Asked Questions
How long does it take to draw up a maintenance plan for a crane system?
Drawing up a basic maintenance plan typically takes één to a few days, depending on the complexity of the system and the number of cranes. A specialized maintenance company such as BKRS can significantly speed up this process by making use of existing templates and years of practical experience.
What are the consequences if I do not have a valid maintenance plan?
Without a valid maintenance plan, you risk fines from the Inspectie SZW, liability in the event of accidents, and shutdown of the installation. In addition, insurance coverage often lapses if it cannot be demonstrated that the system has been regularly certified and maintained.
Can I fully outsource crane maintenance to an external company?
Yes, it is possible to outsource all maintenance — from daily inspections to annual certifications — to a specialized company. Do bear in mind that final responsibility always remains legally with the employer or owner of the installation.
How do I correctly store maintenance records and how long must I keep them?
Maintenance records can be kept both digitally and on paper, as long as they are complete, organized, and traceable. In the Netherlands, it is recommended to keep certification reports and maintenance logs for a minimum of five years, so that they are immediately available in the event of an inspection or incident.
