1. All-aluminum alloy die-casting shell, compact structure and good airtightness.
2. The gears are high-strength helical gears, with low noise and long service life.
3. Power-off brake, stable braking and less wear, safer.
4. High-strength wear-resistant engineering plastics are used as chain guides to reduce chain wear and noise.
5. Frequency conversion control five protections: undervoltage, overheating, overload, overvoltage, overcurrent.
6. High-strength German imported RUD chain, longer service life and more stable operation.
7. All-aluminum alloy handheld handle, more comprehensive protection.
8. Using variable frequency motor, constant torque output ensures sufficient lifting torque.
