Wood handling

Efficiency

High speed as well as a superimposed movement of the crane system enable a high handling performance. With the appropriate log yard design and logistics, over 1 million cubic meters of cut wood per year can be handled with just one crane system in three-shift operation. This means you can replace several pieces of mobile handling equipment at the same time. This also significantly reduces the acquisition and personnel costs. Furthermore, working at wind speeds of up to 8 Bft. (stormy wind) is possible without any problems. In areas with high wind frequency, the systems can also be up to 10 Bft. (heavy storm).

Use of space

A major advantage of the Kuenz portal cranes is the excellent use of space. This means that no area-intensive routes for the rubber-tire equipment or tramlines between the log piles are required. The entire area below the crane system can be used for storage with the exception of the log sorting line, the log tasks and the crane runways. The crane system can be adapted to the required stacking height. Pole heights of well over 12m are possible without any problems. A bevel at the end of the pile is also not necessary, as the crane can access the entire pile length from above.

Economics

Kuenz crane systems impress with their long service life. The cranes are designed for a service life of ≥ 25 years, if necessary, also in three-shift operation. This exceeds by many times the service life of mobile handling equipment. The crane systems are not only easy to maintain, but also extremely low-maintenance and wear-resistant. The crane wheels, for example, last for many years thanks to their special design and heat treatment. Due to the aerodynamic crane design, the low rolling resistance and the energy management including the recovery of the braking energy into the network, the energy costs are significantly reduced.

Environmental friendliness and noise reduction

In addition to the low energy consumption, the fully electric operation means that fossil energy sources can be dispensed entirely. This will significantly improve your company’s green footprint. Additionally, with the exception of the log gripper, we do not use hydraulic drives in our production. This significantly reduces maintenance costs and protects the environment.

While modernizing and expanding systems, operators are constantly dealing with massive noise protection regulations, especially if there are residential areas in the neighborhood. Here, the electrically operated crane systems can also score points over the diesel and hybrid vehicles. Thanks to decades of experience in the field of noise protection, we can work out a noise protection concept tailored to your needs.

Safety and comfort

Gantry cranes make the operation very safe. The optimal position of the crane cabin and assistance systems give the crane driver a perfect overview of the storage area. Due to the crane operation, there are no people or vehicles between or next to the high round timber stacks, which significantly reduces the risk potential. The robust design of the crane system is specially tailored to the handling of logs.

A spacious and air-conditioned crane cabin offers the crane operator a high level of comfort. Compared to mobile equipment, the employee has a very low-vibration and low-noise working environment. Additionally, the crane cabin is equipped with an ergonomic control station and an intuitive crane management system that provides the crane operator with the best possible support.

Reliability

Kuenz crane systems are the most reliable in the world. High availability and short maintenance times guarantee smooth operation. With a permanent remote maintenance connection and an operating data acquisition system which is optimized for the system, we can react quickly and identify any need for action at an early stage.
