Product catalog summary
Classification of Lifting Equipment and Mechanisms
1. Usage Classes and Lifting Cycles
- Severe Intensive Service: 400 cycles, classified from U7 to U9 and A6 to A8.
- Irregular Intensive Service: 100 cycles, classified as U6 and A5 to A8.
- Regular Intermittent Service: 50 cycles, classified as U5 and A4 to A7.
- Regular Light Service: 25 cycles, classified as U4 and A3 to A6.
- Occasional Non-Regular Use: 12.5 cycles, classified as U3 and A2 to A5.
- Exceptional Load Lifting: Structures lifting nominal loads infrequently are classified from Q1 to Q4 based on load frequency.
2. Load Spectrum Class
- Structures are classified based on how frequently they lift nominal loads, ranging from very light to close to nominal loads.
3. Correspondence Table for Movements
- Vertical and Horizontal Movements: Classified by ISO FEM standards with service factors (SF) and starting classes, ranging from M1 to M8 based on the number of starts per hour.
4. Classification According to FEM Rules
- Total Duration of Use: Equipment is classified based on total operational hours and average daily operation time, ranging from T1 to T8 and M1 to M8.
5. Mechanisms Classification
- Mechanisms are classified from L1 to L4 based on frequency of use, from exceptional to regular maximum frequency.
