    摘要: A working platform lifting apparatus for an aerial ladder truck, wherein the working platform movable up and down along the ladder is arranged so that it does not interfere with the extension and contraction of the ladder, that when it is stopped at any desired position it is automatically braked, that when it reaches its uppermost position it is automatically stopped and that in an emergency it can be lowered manually. Other merits and details of the construction will be made clear.
