    摘要: A working range indicating device for an aerial ladder truck is arranged so that the variable length and vertical angle of the ladder are mechanically detected and the detected values are indicated on a working range indicating board disposed at the operating stand by means of a single mechanically operable pointer. Merits and details of the construction will be made clear.
