[0017] like Figures 1-3 As shown, a self-propelled elevated concrete placing boom includes a feeding conveyor 3, a telescopic placing arm assembly 1, and a self-propelled chassis 2. The self-propelled chassis 2 can be a vehicle chassis or a crawler chassis, and the self-propelled chassis 2 facilitates the placing boom's movement on the ground. A raised frame 7 is mounted on the rotating platform of the self-propelled chassis 2. The raised frame 7 includes an inner frame 71, an outer frame 72 that is movably connected to the outer frame 71, and a lifting mechanism 73 for lifting the outer frame 72. The outer frame 72 is slidably connected to the inner frame 71. The lifting mechanism 73 is a lifting cylinder installed within the inner frame 71, and the lifting end of the lifting cylinder is connected to the upper end of the outer frame 72. When the floor height of the material being placed changes, the outer frame 72 is lifted by the lifting cylinder, thereby increasing the height of the telescopic placing arm assembly 1 and adjusting the material placement height. Preferably, the height of the raised frame 7 is 6-9 meters. The base of the telescopic boom assembly 1 is hinged to a support 8 at the top of the outer frame 72. Its front forearm extends outward, and its lower portion is hingedly mounted with an angle-variable mechanism 6 that adjusts the boom assembly's pitch angle. This mechanism 6 is a variable-angle cylinder hinged to the outside of the outer frame 72, with its piston end hinged to the lower portion of the telescopic boom assembly 1. The boom can rotate 360 ​​degrees horizontally on its self-propelled chassis 2. Driven by the variable-angle cylinder, the boom assembly 1 can adjust its pitch angle between -6° and +18°.
