A model arm reduced at a predetermined reduction rate is swingably attached to the side of the boom in front of the operator's cab of the hydraulic excavator and on the side of the operator's cab, and the tip of the boom is A transmission mechanism is used to transmit the swinging motion of the arm between the arm supported by the arm and the model arm, and an elastic body is provided at the free end of the model arm so that the elastic force can be freely adjusted. An indicator rod having a center of gravity at the lower part of the boom is swingably connected, and a bracket having a weight that can be reciprocated in the direction toward the base end of the boom is elastically activated at a position above the weight so that the elastic force can be freely adjusted. A hydraulic excavator characterized in that the hydraulic excavator is supported by a boom so as to be swingable through the body, and a scale plate is attached to the bracket, which is indicated by the indicator rod and has an allowable lifting load scale facing toward the driver's cab. Allowable lifting load display device for use. 2. A model arm reduced at a predetermined reduction rate is swingably attached to the side of the boom in front of the operator's cab of the hydraulic excavator and on the side of the operator's cab, and the arm supported at the tip of the boom and the model are An indicator rod having a center of gravity below the support position is connected to the arm through a transmission mechanism that transmits the swing of the arm, and is connected to the free end side of the model arm through an elastic body that can freely adjust the elastic force. A bracket is swingably connected to the boom and has a weight that is reciprocally movable in the direction toward the proximal end of the boom, and is swingable via the elastic body at a position above the weight so that the elastic force can be freely adjusted. A working radius display device for a hydraulic excavator, characterized in that it is supported by a boom and has a scale plate attached to the bracket that is indicated by the indicator rod and has a working radius scale facing toward the driver's seat.
