Abstract (en)
[origin: WO9913948A1] The object of the invention is a system intended for preventing the freezing of fire extinction water piping (20) in an elevating platform equipment provided with a telescopic elevating boom system (12). The fire extinction water piping extends from the vehicle level to a hydraulic gun (22) arranged in connection with a working cage (15) and comprises a telescopic water piping section (25) running along the elevating boom system (12) as well as piping sections (28, 23, and 24, 27, 29) located on both sides of the telescopic water piping section. The invention is characterised in that the system comprises a circulating water line (30) provided with a circulation pump (35) arranged in parallel with the water piping (20), whereby the ends (31, 32) of the circulating water line are intended to be connected to the water piping (20) on both sides of its telescopic water piping section (25). The invention also relates to a fire extinction water piping and to an elevating platform equipment equipped with said system.
