The utility model provides a frame -type lifing arm for pantograph. There is the maintenance cost in it higher and break technical problem such as contact net easily when the trouble when solving current track transportation vehicles external power. Its technical essential is: its pantograph includes base subassembly (5), support arm, lifing arm, lift power device (4), spring unit (8) and bow subassembly (10), is provided with insulator B (3) in the lower part of base subassembly (5), support arm and the lifing arm activity that forms the linkage frame construction that cranks arm that cooperatees. But its wide application in various track traffics, non - track traffic public transport vehicle, motor driven vehicle's such as haulage truck the electricity that receives is used.
