HEPS-TF is the test facility of HEPS (High Energy Pho-ton Source) of China. The magnet girders are used for supporting and positioning of the magnets. As the beam emittance is very low, the girder must has high adjusting precision and high stability. Besides, the girder should also be beam-based aligned. For these issues, two girder systems are designed. Both of them use cam mover mech-anisms for precision adjustment. One has six cam mover mechanisms and another has eight. The design aim of the alignment accuracy between girders is within 50 μm, and the adjusting resolution is within 3μm. The design aim of the natural frequency is above 30 Hz. This paper will discuss the scheme selection and structural design of the girder systems.
