The low hinged column
Sapa Pole Products’ R&D department designed a low hinged column, with a seamless fitted hinge mechanism, suitable for columns up to 8m. Due to the low weight of aluminium, these hinged columns can be lowered and raised by hand. Depending on the top load, a higher or lower column can be supplied, with or without root section.
The low hinged columns are suitable for lighting as well as signs and cameras, and allow the columns to be lowered for cleaning or maintenance work on the placed equipment.
The hinge mechanism is placed at a short distance above the door entry. After the door is opened, the mechanism can be unlocked from inside the column, by loosening three bolds. A safety-wedge can then be pulled out and the column is ready to be lowered ‘by hand’.
The Sapa low hinged column operation is quick, simple and safe, due to the low weight of an aluminium column. Convince yourself by watching the demonstration movie:
