Detailed Answer
Recommendation: 1. simple needs (hoist/single-speed) → LDER LD-6SK/8SK (price advantage); 2. multi-action crane/gantry → LDER LD-10DK/12DK or Xingjia Xingyao; 3. smart/monitoring needs → Xingjia Xingrui (4G monitoring); 4. extreme protection (IP68) → Xingjia Xingdun; 5. batch purchase → both can negotiate solutions. Both offer 2-year trade-in/warranty with complete after-sales networks. Try samples to compare.
| Simple | LDER |
| Multi-action | Both |
| Smart/EX | Xingjia |
Note:A one-week sample trial beats parameter comparison.
