Abstract:
1. A line tensioning system for regulating tension on a line having a proximal end and a distal end, where the proximal end is operatively connected to a drum, the line tensioning system comprising: a frame defining first and second side edges; a first set of first rollers; a first set of first displacement assemblies, where each first displacement assembly is arranged to displace at least one of the first rollers relative to the first side edge of the frame; a second set of second rollers; a second set of second displacement assemblies, where each second displacement assembly is arranged to displace at least one of the second rollers relative to the second side edge of the frame; whereby the line is arranged such that the line contacts the first and second rollers; and the first and second displacement assemblies displace the first and second rollers relative to the first and second edges based on a tension on the line.
