Rope Access Services

Rope access is the professional use of ropes to do inspections, maintenance, and other types of work. The application of Rope Access can often be a cost-effective, and safer method for works at height, as well as jobs in difficult to reach spaces. Davai has extensive knowledge and experience within the use and application of Rope Access.

Rope access system is a safe method of working at height where ropes and associated equipment are used to gain access to and from the work position, and to be supported there.
The advantage of using rope access methods mainly lies in the safety and speed with which workers can get to or from difficult locations in order to carry out their work, often with minimal impact on other operations, surrounding areas and the environment.
