Not all tree work can be done using exterior means such as elevated platforms or ladders. In this case, to move and work, the arborist uses rope progression techniques.
Examples of operations: ornamental tree trimming, to adapt the tree to its environment or to change its overall aesthetic maintenance trimming to remove dead wood and dying branches tree removal (progressive cutting of the trunk from the top) if diseased or presenting a hazard...
Technical specifics: access from the base of the tree generally starts by throwing a weighted bag with line attached. This line is used to install the access rope on an anchor up in the tree while moving about on the branches, the arborist keeps his/her weight on the work rope, for greater stability and to reduce potential fall distance when using any cutting tool (handsaw, chainsaw), the arborist must use two independent belay systems
