Detailed Answer
Two-speed control: each action key has fast/slow two levels (light press for slow, firm press for fast, or toggle between them by pressing twice), enabling high-speed travel + low-speed inching positioning. Two-speed in industrial remotes is implemented via contactor two-speed (dual-winding motors) or VFD two-speed. LIDEER LD-8SK/LD-10DK two-speed models are the workshop crane standard, with centimeter-level inching precision.
| Implementation | Contactor/VFD two-speed |
| Operation | Light slow, firm fast |
| Precision | Centimeter-level |
Note:For high positioning accuracy, confirm the two-speed low gear is slow enough.
