An engineering solution developed by SEIK that pushes beyond the limits of conventional cranes, opening up new possibilities for lifting and material handling, even on the most challenging construction sites.
A new dimension in lifting and material handling
Skytruck combines the advantages of traditional overhead cranes with the most advanced cable systems, offering an alternative to conventional cranes, particularly in locations where terrain characteristics and operating conditions make traditional solutions difficult to deploy.
The system is based on a beam suspended on cables, with movement controlled by a ground winch or an integrated translation system. Its dual pair of support cables (3S system) ensures great stability and smooth movement, providing a versatile solution that is easy to operate and designed to optimise both efficiency and safety.
The result is a technology engineered to adapt to the specific characteristics of each construction site, addressing situations where accessibility, environmental conditions and safety are critical factors.
Reduced environmental impact, greater design flexibility
One of Skytruck’s key strengths is its ability to reduce the construction work required for system installation.
The reduced footprint of the foundation works helps keep construction costs down while minimising the environmental impact of the construction site. Once operations are completed, the site can also be restored more easily and quickly.
The system’s configuration offers a high degree of flexibility: its overall length can be adapted to the characteristics of the site without changing the width of the area served. The coverage area can also be expanded by installing multiple Skytruck systems in parallel.
These benefits are complemented by several key operational features:
- Load Stability: Precise and rapid positioning with high stability and minimal load oscillation, even under extreme environmental conditions.
- Precise and Controlled Movement: Full load control in every position, with radio control or operator cabin.
- High productivity: Reduces working times, increasing overall jobsite efficiency.
- Simple, Intuitive interface: Designed for ease of use, enabling faster and safer operations.
Technological evolution driven by experience
Since its debut in 2004, Skytruck has undergone continuous development, driven by new applications and engineering challenges. In 2008, the first Skytruck 100 version was introduced, featuring a closed-loop system. In 2010, the Skytruck 400 followed, with a lifting capacity of up to 40 tonnes.
The range was further expanded in 2025 with the introduction of Skytruck 300, developed for dam construction projects, offering a 30-tonne lifting capacity and a 40-metre cross-travel span.
Over the years, the different configurations have enabled SEIK to meet increasingly specialised operational requirements.
Five models for different requirements
The Skytruck range includes several configurations designed to meet different lifting capacity and operational coverage requirements.
Depending on the model, the system can be operated via remote control or from an operator’s cabin. This comprehensive range makes it possible to identify the most suitable configuration for each project’s specific characteristics, combining lifting capacity, working area dimensions and operating modes.
One technology, multiple applications
From major infrastructure projects to the mining and energy sectors, Skytruck can be used in a wide range of applications. These include the construction and maintenance of bridges, dams and industrial roofs, the extraction of aggregates from riverbeds and the construction of reservoirs.
It is also used for the installation and maintenance of penstocks, as well as in pumping and pumped-storage facilities, where it facilitates material handling even in rugged terrain and areas with significant elevation differences.
Among its most significant references are the Chenab Rail Bridge in India, an outstanding example of the technology’s application in an exceptionally challenging infrastructure environment, and a dam construction project in Saudi Arabia, for which SEIK developed and supplied the Skytruck 300 system.
Chenab Bridge: An Engineering Challenge on an International Scale
For the construction of the Chenab Rail Bridge in India, SEIK supplied a Skytruck 400 system to handle materials throughout the construction site.
The 1,315-metre-long railway arch bridge, standing 356 metres above the riverbed, is located in a remote area characterised by extreme weather conditions and exposure to seismic activity.
To meet the project’s logistical requirements, Skytruck 400 was installed along a 915-metre horizontal track, with a configured lifting capacity of 20 tonnes and a span of 40 metres.
This is a tangible example of Skytruck’s ability to operate in complex infrastructure environments, where accessibility and environmental conditions call for tailor-made engineering solutions.
Saudi Arabia: a new application for Skytruck technology
For the construction of a major dam in Saudi Arabia, SEIK supplied a Skytruck 300 system designed to handle both materials and personnel throughout the construction site.
Featuring a 720-metre span, a 40-metre-wide cross beam and a lifting capacity of up to 30 tonnes, the system was engineered to serve an operational area of more than 28,800 m², ensuring precision and reliability in transport operations.
The solution also made it possible to limit the civil engineering works required and reduce the environmental impact of the construction site, marking the debut of the Skytruck 300 in the SEIK product range.
SEIK: Experience, Innovation and an International Vision
Today, SEIK draws on extensive experience in the design and manufacture of ropeway transport and material handling systems.
The figures tell the story of the company’s international growth: more than 90 turnkey projects designed, operations in over 20 countries and more than 350 carriages manufactured.
Skytruck represents one of the clearest expressions of this expertise: a technology born from hands-on experience, continuously developed through innovation and adapted to the specific requirements of every project.
