Ascenders & Descenders for Arborists

Here you will find equipment for both ascending and descending – the core of modern climbing systems for arborists. The combination of ascenders and descenders makes it possible to move efficiently, controllably, and with less energy expenditure throughout the entire work process in the tree.

How the systems are used in tree work

Ascending (SRT) – ascenders and mechanical climbing systems make long ascents faster and less physically demanding.
Work positioning – fine-tune height and working position during pruning or dismantling.
Movement in the canopy – smooth transitions between workstations.
Descending – descenders provide controlled and safe descent.

Systems for both SRT & DdRT

This category includes solutions for both Single Rope Technique (SRT) and Doubled Rope Technique (DdRT). Modern mechanical devices provide even friction, less rope wear, and better control – especially during long working days in a harness.
