Detailed Answer
Restricted installation scenarios: 1. hazardous areas without explosion-proof models (red line); 2. equipment without safety protection (no e-stop circuit/overload limiter); 3. special equipment not inspected (modification must be compliant); 4. extremely hostile signal environments (unresolvable strong interference); 5. prohibited by regulations (some special operations). All other conventional hoisting equipment can be fitted. When unsure, consult the manufacturer/regulator; LDER provides installation assessment.
