1. DC permanent magnet synchronous motor (PMSM) and servo control technology.

2. The motor has the same performance as the main motor of the CNC machine and electric vehicle. It has high control precision, high torque density, good torque balance, low power consumption, high efficiency, and low noise.

3. Double extension spring crank transmission design, for a more stable and reliable structure.

4. Reasonable balance design makes less dependence on spring and easier adjustment and less maintenance.

5. No limit switch design, accurate encoder detection, detecting boom position when power on.

6. Manual clutch design: When power-off, open the manual hand-wheel clutch to move or lock the boom at any position by hand directly. (patented technology)

7). More sensitive and reacting faster when reversing upon obstacles.
8). With counting, delay auto-closing, and auto-aging test function.
