Key technology innovation
Hoisting molten metal hoistAdded special requirements: 12 special clauses such as double protection of safety brake, chain safety factor ≥6.3, and anti-radiation heat design, among which the rated lifting weight limit is ≤16t.
Energy efficiency testFor the first time, the GB/T 30028 method is introduced, which is required to comply with the JB/T 12745 energy efficiency limit standard.
Implementation points
- Working levels M1-M8 correspond to different test cycles (20-12,500 hours)
- Static load test 125% rated load for 10 minutes
- Dual-speed hoist slow speed must reach 1/6-1/2 of normal speed
- Safety clutch load limit 130%-160% rated lifting capacity
Typical application scenarios
A steel plant uses a 10t M6-level chain hoist to lift a ladle, with the following configurations:
- Dual brakes (working + safety)
- T-level high-precision lifting chain
- High-temperature-resistant F-level insulation motor
- Non-following remote control
