The installation of a KBK crane system follows a structured process that begins with thorough preparation and ends with an official inspection. On average, the full assembly of a light crane takes one to several days, depending on the complexity and scale of the system. In this article, we answer the most frequently asked questions about installing a KBK crane, from preparation to completion.
What preparations are required before assembling a KBK crane system?
Before assembling a KBK crane system, a structural inspection of the facility, a custom technical design, and a clear planning schedule are essential. Without these steps, you risk delays or unsafe situations during and after installation. Thorough preparation is therefore the foundation for a smooth and safe assembly of the light crane.
Specifically, the preparation phase includes the following steps:
- Structural assessment: The load-bearing structure of the facility, such as columns, beams, and floor, is checked for suitability for the intended load.
- Technical design: Based on the lifting capacity, the runway, the working area, and the specific process requirements, a custom drawing is produced.
- Permits and documentation: Relevant technical documentation and any required building permits are collected and approved.
- Logistical planning: Delivery times for components, availability of installers, and the operational schedule of the company are coordinated.
- Clearing the work area: The installation site must be free of obstacles so that installers can work safely and efficiently.
The more carefully these preparations are carried out, the less chance there is of unexpected problems during the assembly of the KBK crane system itself.
What does the step-by-step assembly process of a KBK system look like?
The assembly process of a KBK system follows fixed steps: first the rail profiles are installed, then the trolleys and hoisting equipment, and finally the electrical installation. This sequence ensures a stable and safe build-up of the complete crane system.
A typical assembly process looks as follows:
- Setting out and marking: The exact positions of the suspension points and rail profiles are measured and marked on the structure of the facility.
- Attaching the suspension structure: Brackets or consoles are attached to the existing building structure in accordance with the technical drawings.
- Installing the rail profiles: The KBK rail profiles are placed on the suspension structure and carefully levelled.
- Placing trolleys and hoisting equipment: The crab, hoist chain or hoist strap, and any balancing devices are mounted on the rails.
- Electrical connection: The power supply, controls, and any pendant controls are connected and tested by an electrician.
- Functional check: All movements and functions are manually run through to verify that everything works correctly before the official inspection.
How long does the installation of a KBK crane system take?
The installation of a KBK crane system typically takes one to three working days. The exact duration depends on the scale of the system, the number of runways, the complexity of the electrical installation, and the structural conditions on site.
A simple single-runway system in a small facility can be assembled in one day. Larger installations with multiple runways, complex control systems, or special adaptations require more time. Delays often arise from unforeseen structural modifications or changes in the client’s planning. A realistic time estimate in advance, based on a thorough on-site survey, prevents surprises.
What does the inspection and testing procedure after assembly involve?
After the assembly of a KBK crane, a mandatory inspection follows in which the system is tested for safety, load capacity, and correct operation. This inspection must be carried out by an accredited inspection body and results in an inspection report that is legally required before the system can be put into service.
The testing procedure typically includes:
- Visual inspection: Checking all connections, fastenings, welds, and components for visible defects or deviations.
- Load test: The system is loaded with a test weight that exceeds the nominal lifting capacity, in order to verify the safety margins.
- Functional test: All movements, emergency stops, limit switches, and control elements are systematically tested.
- Documentation: The results are recorded in an inspection report, including the permitted lifting capacity and the date of the next periodic inspection.
After approval, the KBK crane may officially be put into service. Periodic re-inspections, typically annual, are subsequently mandatory to continue guaranteeing safety.
Who is responsible for the installation of a KBK crane?
Responsibility for the installation of a KBK crane lies with the specialised crane manufacturer that supplies and assembles the system. The client, as employer, bears ultimate responsibility for the safe commissioning and maintenance of the crane at their location.
In practice, this means that the crane manufacturer is responsible for the correct design, assembly in accordance with the technical specifications, and supervision of the inspection. The client is responsible for providing a suitable work area, informing the installers of location-specific risks, and complying with the statutory inspection and maintenance obligations after completion. A clear written delineation of responsibilities, recorded in the quotation or contract, prevents disputes after the fact.
What are the most common problems during the installation of a KBK crane?
The most common problems during the installation of a KBK crane system are insufficient load-bearing capacity of the existing building structure, dimensional deviations on site, and incomplete or incorrect technical documentation. These problems can in most cases be prevented with thorough preparation.
Structural bottlenecks
It regularly becomes apparent during assembly that the existing roof structure or columns cannot support the calculated load. This requires additional reinforcements, leading to extra costs and delays. A structural survey prior to the quotation prevents this kind of surprise.
Dimensional deviations and planning errors
Discrepancies between the drawings and the actual situation on site are a common cause of delay. Think of columns that are not in the expected position or floors that are not level. Accurate on-site measurement, combined with good coordination between the drawing office and the assembly team, significantly minimises this risk.

Frequently Asked Questions
Is a building permit required for the installation of a KBK crane system?
That depends on the situation. In many cases, technical documentation and an inspection report are sufficient, but if significant structural modifications to the facility are required, a permit may be necessary. Your crane manufacturer can advise you on this during the preparation phase.
How often must a KBK crane be inspected after commissioning?
A KBK crane system must typically be re-inspected annually by an accredited inspection body. As an employer, you are legally obliged to have these periodic inspections carried out and to keep the associated documentation on file.
Can a KBK crane system be extended or modified at a later stage?
Yes, one of the great advantages of the KBK system is its modular construction, which makes extension or modification relatively straightforward. However, every significant modification requires a new inspection before the modified system may be put into service.
What happens if the existing facility cannot support the load of the KBK system?
In that case, additional structural reinforcements are required, such as extra columns or strengthened beams. This leads to additional costs and a longer lead time, but can in most cases be resolved effectively. A thorough structural survey prior to the quotation prevents this from coming as a surprise.
