null Development of hybrid skidder HiSkid Logo null null

Features

The skidder is defined as a self-propelled, articulated forest vehicle for skidding trees or parts of trees.
The skidding is the removal of entire trees or parts of the tree (trunk, wood assortment) from the felling and processing site to the roadside landing.

Primjena U Hrvatskoj

Application in Croatia

In Croatia, the use of skidders began in 1968, in the 1970s a period of intensive mechanization began until the end of the 1980s when the required number of skidders was reached around 300.

Privlačenje Drva

Timber extraction

Timber is extracted with one end of the load lifted of the ground and leaned on the rear part of the vehicle, while the other part of the load is dragging on the soil.

Tehničke Značajke

Technical features

Increased lateral stability of the skidder when working on a slope or when crossing over surface obstacles is enabled by swinging front axle.

O Skideru

About the skidder

Skidders are an important part of the forestry machinery that is produced and used in Croatia. Existing skidders are powered by diesel engines, and in order to reduce the cost of use and meet increasingly stringent emission standards, the project aims to offer a conceptual design of a hybrid skidder, which includes sizing of drive components, customization of tools and designing management using modern optimization procedures based on precise and computationally efficient mathematical models and real data of the modes of operation of skidders measured on hilly and mountain terrain. For this purpose, it is necessary to carry out field measurements on existing vehicles, and then to carry out an adequate analysis of the collected data, which is, after processing, used as a basis for the development of hybrid and electric forest vehicles. The project envisages the development of an experimental setup of an electro-hydraulic winch in order to produce a precise mathematical model intended to select a suitable winch drive that will fit into the hybrid drive of the skidder and to design the operation of such a winch. Finally, the goal of the project is to offer a conceptual design of a hybrid skidder that will be the basis for a prototype that can be further marketed as an innovative product of high added value.
