Kesla Launches New F-Series Forestry Cranes – Performance, Controllability and Modularity for the Most Common Forwarder Classes

As timber harvesting operations demand higher productivity, improved operator control and greater versatility across applications, Kesla introduces its new generation of forwarder cranes. The new F-series covers the size classes KESLA 9F/FT, 10F/FT, 12F/FT and 14F/FT. The range has been developed to meet these evolving industry requirements by combining performance, precision and modularity with proven durability and life-cycle efficiency.

The four size classes in the new range offer a gross lifting moment of 120–180 kNm, covering a wide spectrum of the most common forwarder sizes. Each model is available both as a single-extension F-version (reach 8.2 m) and a double-extension FT-version (reach 10.07 m), enabling an optimal solution for varying operational and reach requirements. Two different pillar height options for each model allow flexible integration with different base machines and applications.

Designed as a complete range from the ground up

The KESLA F-series has been developed as a unified product family, where key structural solutions and operational characteristics remain consistent throughout the range. This supports:

• efficient production,
• easy maintenance,
• a consistent user experience,
• smooth integration with OEM partner machines,
• efficient spare parts management.

During development, extensive customer feedback from existing cranes on the market was collected and combined with comprehensive field testing across different markets. The cranes have been tested in multiple applications and on various base machines, with highly positive user feedback – particularly regarding motion control, power feel and swing torque.

Key benefits for the operator

Performance: strong lifting torque and smooth power delivery across the entire working range.

Controllability: precise and predictable movements in all working situations.

Geometry: optimized boom dimensions, efficient operation with minimal crane movement.

Durability: thoroughly tested structure both in forest conditions and on test benches.

Serviceability: designed for easy maintenance.

Smart hydraulics: proven hose routing solutions and component selection; internal hose routing inside the extension boom is a patented solution.

Modularity and flexibility

The modular design of the F-series enables a wide range of configuration options to meet different customer needs. The cranes are compatible with various link options and offer multiple pillar height alternatives, facilitating integration with different base machines and applications. The modular approach also minimizes the number of spare part items, supporting efficient product support.

Thanks to the versatility of configurations, the new F-series cranes are also well suited for feeding chippers and other industrial applications.

Kesla’s strategic investment in the crane market

The new F-series is a key element of Kesla’s strategy to strengthen its position as one of the leading manufacturers of forestry cranes. With this range, Kesla provides a comprehensive and competitive solution for the entire CTL harvesting chain.

“The F-series represents a new level in Kesla’s crane development. By listening closely to crane users, we have combined our long experience with modern product development to create a product family that meets the needs of both machine manufacturers and contractors well into the future,” says Mika Tahvanainen, Product Management Director at Kesla Plc.
