Welcome to our knowledge hub, where we delve into essential topics to empower you in making informed decisions for your lifting operations. Today, let's explore the crucial realm of "Crane Working Class Standards" – a foundational element in the world of cranes that significantly impacts operational efficiency, safety, and equipment longevity.
This is the corresponding standard for each level of hoist and crane levels for better understanding crane working class standards.
Hoist Classification | Corresponding Crane Class | Corresponding Crane Class | |||
FEM | HMI | ISO/CHINA | CMAA | DIN 15018 & SIM. | EXAMPLE |
| 1Cm | H1 | M2 | CLASS A | H1/B2 | 1. Maintenance crane in machine house 2. Used only occasionally |
1Bm | H2 | M3 | CLASS B | H1/B2 | 1. Light duty work shop crane 2. Single shift operation 3. Low average loads 4. Maximal load lifted occasionally |
1Am | H3 | M4 | CLASS C | H2/B3 | 1. Light/Med duty work shop crane 2. Single shift operation 3. Medium average loads 4. Occasionally lifting of max load |
2m | H4 | M5 | CLASS D | H2/B3 | 1. Heavy duty crane, 2 shift operation 2. 1 or 2 shift operation 3. Regular medium and heavy loads |
3m | H4 | M6 | CLASS D | H2/B3 or H3/B4 | 1. Med/heavy duty work shop crane 2. Nominal load regularly lifted 3. Traverse or other dead loads below the hook |
4m | H4 or H5 | M7 | CLASS D or CLASS E | H3/B4 or H4/H6 | 1. Very heavy duty crane 2. 2 - 3 shift operation 3. Grab or magnet below the hook 4. Regular heavy loads |

Duty Cycle: Different classes represent varying duty cycles, from light to heavy. Assessing your operational requirements is the first step in determining the ideal working class for your crane.
Load Spectrum: Each working class is designed to handle a specific load spectrum. Accurate assessment of your lifting requirements ensures optimal crane performance and longevity.
Operational Conditions: Consider the environmental factors and operational conditions your crane will encounter. Working class standards guide you in selecting a crane that can withstand the demands of your work environment.
Operational Efficiency: Matching your operational needs with the right working class ensures seamless and efficient lifting processes.
Safety Assurance: Adhering to appropriate standards guarantees a safer working environment for your team and assets.
Equipment Longevity: Choosing the correct working class contributes to the longevity of your crane, minimizing downtime and maintenance costs.
