An extendable lifting beam is available in various lengths, depending on your specific lifting needs. The most common lengths range from 1 to 3 meters for compact applications to extensive systems of 20 meters or more for industrial lifting operations. The right length depends on your work area, lifting height and safety requirements. This overview covers all aspects of extendable lifting beams and their available lengths.
What are extendable lifting beams and how do they work?
Extendable lifting beams are adjustable support beams that can increase their length through telescopic sections. They consist of multiple interlocking parts that can be extended hydraulically, mechanically or manually. The working principle is based on an inner and outer beam that slide over each other, making the total length flexibly adjustable.
The major advantage over fixed lifting beams is the flexibility in work area. With one system you can serve different spans without needing multiple cranes. This saves space, costs and installation time. The telescopic function makes it possible to work in tight spaces while still having a large working range when needed.
Modern extendable systems are equipped with safety mechanisms that prevent sections from retracting unintentionally during use. Locking systems ensure that the desired length remains stable, even under heavy loads.
What standard lengths are available for extendable lifting beams?
The industry offers a wide range of standard lengths for extendable lifting beams. Short versions range from 1 to 3 meters and are ideal for workshops, garages and smaller production spaces. These compact systems provide sufficient flexibility for general lifting tasks without taking up much space.
Medium-sized systems cover lengths from 4 to 10 meters and are popular in manufacturing. These configurations offer a good balance between reach and stability. For large industrial applications, extendable lifting beams are available up to 20 meters or more, suitable for shipbuilding, the steel industry and large assembly processes.
The standardization around these lengths stems from practical considerations such as transport, installation and cost-effectiveness. Manufacturers focus on these popular sizes because they meet most industrial needs and are efficient to produce.
How do you determine the right length for your lifting application?
Determining the right length starts with measuring your work area and identifying the maximum span you need. Always add 10 to 15% extra length for unforeseen situations and future expansions. Consider obstacles such as columns, walls or other equipment that may limit the working range.
Safety factors play a crucial role in length calculation. Longer extendable systems need more support and may have limitations in load capacity when fully extended. Always check the technical specifications for maximum load at different lengths.
Also consider future needs. If your business grows or processes change, a slightly longer lifting beam may provide cost savings in the long run. Consult with specialists about the optimal configuration for your specific situation and growth expectations.
What is the difference between single and multiple extendable lifting beams?
Single extendable lifting beams consist of two main sections: a fixed base and one extendable part. This simple configuration offers reliability and is suitable for applications where doubling the base length is sufficient. They are cost-effective and require less maintenance due to their simpler mechanism.
Multiple systems have three or more telescopic sections, allowing for much greater reach. A three-section system can, for example, extend from 3 meters to 9 meters. These configurations are ideal for situations where maximum flexibility is required, but do require more maintenance and have higher purchase costs.
The choice depends on your specific needs. For regular variation in work area, multiple systems are worth the investment. For occasional use or limited variation in span, a single version is often sufficient.

Frequently Asked Questions
What are the maintenance costs of extendable lifting beams?
Maintenance costs vary depending on complexity and frequency of use. Single systems cost an average of €500-800 per year, while multiple systems can cost €1000-1500. Regular lubrication and annual inspections are essential for optimal performance.
Can extendable lifting beams be automated?
Yes, modern extendable lifting beams can be equipped with automatic control systems. This includes programmable length positions, remote control operation and integration with existing crane systems for fully automated lifting operations.
How long does installation of an extendable system take?
A standard installation usually takes 1-3 days, depending on the complexity and length of the system. Custom systems or installations in existing buildings can take 5-7 days, including engineering and testing phases.
What happens if the extension mechanism gets stuck during use?
Modern systems have emergency procedures and manual override functions. In case of malfunction, the system must be shut down immediately and may only be repaired by certified technicians. BKRS offers 24/7 breakdown service for such situations.
