Abstract: The structure and dynamic parameters of the crawler electric working platform were developed according to the requirements of the multi-ecological three-dimensional planting mode for mechanization and the agronomic parameters of the new planting mode. Through describing  the structure and working principle of the  whole machine, the structural design and dynamic parameter calculation of the key components such as crawler power chassis and hydraulic lifting platform had been  carried out. At the same time, the drive control system had been developed. The driving speed, endurance and minimum passing circle tests were carried out on the electric working platform. The test results showed that the electric working platform had achieved the design requirement of rated load of 200 kg. The average driving speed of slow-speed gear was 0.40 m/s, and the average driving speed of fast-speed gear was 0.98 m/s. The operating endurance under 100 kg load could reached 4.69 h, and the power supply of lithium battery was stable. The minimum passing circle diameter was 1.54 m. At last but not least, the performance indexed that the crawler type electric working platform had realized the mechanized material handling and auxiliary ascent operation in multi-dimensional ecological planting facilities.
