摘要（英）：

The utility model relates to a self-propelled overhead working platform, belonging to the field of engineering machines. The self-propelled overhead working platform is provided with a chassis; the chassis is connected to a rotating table by a swing mechanism; and an extending arm frame comprises a I arm oil cylinder, a I arm lower beam, a I arm upper beam, a main arm support, a main arm oil cylinder, a lower leveling oil cylinder, a main arm, a telescopic arm oil cylinder, a telescopic arm, a forearm lower beam, a forearm oil cylinder and a forearm upper beam. The self-propelled overhead working platform is characterized in that a forearm oil cylinder main push rod and a forearm oil cylinder side push rod are arranged between the forearm upper beam and the forearm oil cylinder; one end of the forearm oil cylinder main push rod, one end of the forearm oil cylinder side push rod and one end of the forearm oil cylinder are hinged together by a forearm oil cylinder shaft; the other end of the forearm oil cylinder main push rod is hinged to the front end of the forearm upper beam by a forearm front shaft; the other end of the forearm oil cylinder side push rod is hinged to the forearm upper beam in the middle by a forearm central shaft; the other end of the forearm oil cylinder is hinged to the telescopic arm; the front ends of the forearm lower beam and the forearm upper beam are hinged to a connecting plate; and the telescopic link of an upper leveling oil cylinder is hinged to an oscillating cylinder seat.
