Method for regulating the traction in a line of a device to help climb a ladder and device to help climb a ladder.

摘要

A method for regulating the traction in a line (13) of a device to help climb a ladder, which method comprises the steps of: - sensing any movement of the line (13); and - when no traction is applied to the line (13) and movement of the line is sensed for a predetermined first period of time, the traction is increased to a predetermined high level (L1); and - when traction is applied to the line (13) and movement of the line is sensed for a predetermined second period of time, the traction is maintained at the predetermined high level (L 1); and - when traction is applied to the line (13) and no movement of the line is detected during the predetermined second time period, the traction is decreased to a predetermined low level (L0).
