Dual axis solar tracking system is 
" altitude angle + azimuth" full-tracking system, it moves along two rotation axes with two rotational degrees to completely track the sun's orbit and maximize solar energy reception. This kind of slewing drive is suitable for high-latitude areas and the efficiency of power generation will be increased over 35%, which significantly improve the efficiency of solar power generation system.

Double worm drive rotary driver and special type rotary driver,heavy duty slewing drive.

Three advantages of rotary drive:

Due to the high integration of the slewing drive, the user does not have to purchase and process each component constituting the rotating device one by one, which also reduces the preparation process at the beginning of the production to a certain extent, thereby greatly improving labor productivity.


The worm gear drive has the characteristics of reverse self-locking, which can realize reverse self-locking, that is, the worm wheel can only be driven by the worm, and the worm wheel can not be driven by the worm wheel. This feature makes the rotary drive widely used in lifting, aerial work and other equipment. While improving the technical content of the mainframe, it also greatly improves the stability of the main machine and the safety factor of the operation. Compared with traditional rotary products, the slewing drive is easy to install, easy to maintain, and saves installation space.
