Detailed Answer
Dual-speed control: each action has two speed levels - high speed (fast travel) + low speed (precise positioning). Implementation: dual-speed motor (dual winding) or multi-step VFD speed. Dual-speed remote models (from Leader LD-8SK) output the corresponding two levels. Use low speed for lifting positioning and precision work; high speed for empty travel. Dual-speed is a standard feature of bridge crane remotes.
| High speed | Fast transfer |
| Low speed | Precise positioning |
| Implementation | Dual-winding / VFD |
Note:Get into the habit of using low speed for positioning work; it is safe and efficient.
