High-Precision Servo Lifting & Rotating Module for AGV/AMR

1. Background: The Demand for Multi-Axis Lift & Rotation in AGV Systems

As flexible logistics and smart warehousing evolve, AGVs and AMRs are required to perform more complex operations like lifting shelves, rotating pallets, and precise docking.

We offer a servo-driven lifting & rotating module series, with load capacities of 300kg, 500kg, 1500kg, and 3000kg, widely applied in AGV lift units, AMR rotary platforms, and automated warehouse handling systems.

2. Structure: Dual Independent Servo Motors for Accurate, Responsive Control

The lifting & rotating module features:

• A trapezoidal lead screw (T32×5) combined with a planetary gearbox for vertical motion, delivering stable lifting under heavy loads;

• A servo + gear reducer mechanism for rotation, enabling ±180° precise positioning and fast response.

Its compact, modular design allows for flexible integration into AGV/AMR platforms that demand high-frequency operation and accurate alignment.

3. Self-Locking Design: Brake-Free, Safer, and Easier to Maintain

The trapezoidal screw ensures natural self-locking, allowing the lifting platform to hold position even during power loss, with no need for a motor brake.

This enhances the safety and reliability of AGVs and AMRs in real-world conditions such as emergency stops, docking delays, or power-off holding—reducing mechanical complexity and minimizing maintenance.

4. Motion Resolution (Based on 500kg Model)

• Lifting Resolution: Gear ratio 30, pitch 5mm

$$1÷30\times 5=\mathbf{0.166}\mathbf{m}\mathbf{m}\mathbf{/}\mathbf{p}\mathbf{e}\mathbf{r}\mathbf{m}\mathbf{o}\mathbf{t}\mathbf{o}\mathbf{r}\mathbf{t}\mathbf{u}\mathbf{r}\mathbf{n}$$

Suitable for precise vertical positioning within ±0.5mm tolerance.

• Rotation Resolution: Gear ratio 30, gear set 6

$$360\mathrm{°}÷(30\times 6)=\mathbf{2}\mathbf{°}\mathbf{/}\mathbf{p}\mathbf{e}\mathbf{r}\mathbf{m}\mathbf{o}\mathbf{t}\mathbf{o}\mathbf{r}\mathbf{t}\mathbf{u}\mathbf{r}\mathbf{n}$$

Supports ±180° rotation for pallet orientation or docking adjustment.
