Detailed Answer
Selection steps: 1. List equipment actions (hoist/trolley/gantry/aux. hook → 6-12 keys); 2. Determine speed needs (single/dual/proportional); 3. Assess environment (indoor/outdoor/dust/salt spray → IP65-68); 4. Evaluate communication needs (distance/obstacles → frequency + antenna); 5. Define safety requirements (emergency stop/signal loss protection/key/RFID); 6. Verify certifications (explosion-proof zones/export); 7. Set budget (LDER ¥268–¥978 / XINGJIA ¥350–¥1,800). Compare all factors before selecting.

| Environment | Protection |
| Budget | LDER / XINGJIA |
Note:Use a checklist for selection — don't rely on intuition.
