According to the Nanning municipal engineering administration office in recent days, in order to solve the problem that the lifts of footbridges often malfunction in summer after startup of overtemperature protection system, Nanning refitted 3 footbridge lifts on Xinghu Road. So far, the refitting of the No. 3 lift has been completed and that of the other two is still ongoing which are expected to be opened to the public recently.
It is learned that the difficulty of the work mainly lied in working aloft and it is required that the original tempered glass shall be dismantled and the original shaft frames shall be welded without affecting the lift components. During the refitting, a rain-proof deflection grille would be installed below the roof slab of the lift shaft for driving gas flow and ventilation; and the original tempered glass would be replaced by aluminium-plastic panels as sunshade for cooling the lift.
