Based on UK rationalised wind loading factors for EN40
The spring unit, type RLS168, is available in a range of coloured springs. Each spring type has a given capacity, based on the column height and maximum safe working load.
This hydraulic unit is popular with companies who have multiple column heights and headloads on one site or over a number of sites.The advantage is that it can operate the full column range regardless of height and headload.
