Hæhre Entreprenør has implemented a groundbreaking remote-controlled Caterpillar D8 dozer in the extensive land reclamation project at Frier Vest in Grenland. This initiative is part of Norway's largest earthmoving operation, aiming to create 3,700 acres of industrial area and a port terminal. The project involves moving an impressive 3.2 million cubic meters of rock, with 1.2 million cubic meters forming the foundation for the new port terminal

The remote-controlled dozer is an essential part of this massive undertaking, allowing for safe and efficient material handling even in challenging conditions. The machine is primarily used to manage the redistribution of materials brought in by up to 14 dump trucks, including Caterpillar 772G and 775G models, as well as fully electric Sany SKT105E.
These trucks unload at a safe distance from the reclamation area, and the dozer then pushes the material into place. By utilizing remote operation, the operator remains at distances up to 1 km away from the machine, significantly reducing the risk of accidents associated with landslides or unstable ground conditions.
Steer has developed a cutting-edge control system for Caterpillar bulldozers, spanning from the smaller D6 up to the mighty D11. This system allows for comprehensive command over the machine through a user-friendly interface, ensuring that the operator has full control without being physically present in the danger zone. The dozer is equipped with Trimble machine control technology, which automates leveling and ensures that the landfilling process remains precise and consistent. This integration guarantees that the filled areas are as level as if they were completed manually, but with the added benefit of safety and efficiency.
The use of GPS-guided movements and semi-autonomous blade control ensures that the dozer's performance matches that of traditional manned operations. The integration of Trimble’s advanced positioning systems allows the machine to operate with super high accuracy, even when handling large volumes of material. This precise control is crucial in a project of this scale, where the aim is to create a stable and even surface across a vast area. All functions are controlled from the remote operator control station.

One of the most significant advantages of using a remote-controlled dozer is the enhanced safety it offers - removing the operator from the machine itself. The risk of injury due to landslides or ground instability is significantly minimized. This is particularly important in land reclamation projects, where uneven and loose terrain can pose severe risks.
Alf Mikkelsen, one of Hæhre's most experienced dozer operators, emphasizes the positive impact of the technology: "It feels incredibly good to carry out this work in a safe and efficient way. During my career, I have unfortunately seen severe accidents happen when operators could not be saved. This solution not only protects us but also maintains the productivity we need on such a demanding project."
Project Director Asle Ståland at Hæhre is highly satisfied with the implementation of the remote-controlled dozer: "This technology allows us to deliver efficiently on demanding projects without compromising operator safety. We have seen great results so far, and the feedback from our operators has been overwhelmingly positive."
The well developed solution from Steer demonstrates how modern technology can be integrated into traditional construction methods to create safer and more efficient workflows. As the demand for innovative solutions continues to grow, Steer aims to further develop and adapt the remote control system for use in other large-scale infrastructure projects.
By pushing the boundaries of remote operation and integrating advanced machine control technologies, this project at Frier Vest serves as a model for future construction sites where safety and efficiency are paramount.
