Crane Sheave (Pulley Block) is intended for crane maintenance, modernization and system integration. Available configurations include capacity: 1 – 100 tons (per sheave block). The final configuration should be matched to the actual load, site layout and operating frequency.
Typical Applications
Crane maintenance, modernization and system integration.
What to Confirm Before Ordering
- Confirm the required dimensions, load rating and connection details.
- Share equipment drawings or clear photos so interfaces can be checked.
- Specify the working environment, operating frequency and required standards.
Send us your project requirements and available drawings. Our engineers will check the main dimensions, duty class and safety configuration before quotation.
| Soft groove → rope rubs & frays in weeks | Hardened groove surface (HRC 45-50) – rope slides smoothly, lasts 3x longer |
|---|---|
| Wrong groove size → rope jumps/squeals | Precision groove match – we size groove to YOUR rope diameter (±1mm tolerance) |
| Capacity Range | 1 – 100 tons (per sheave block) |
| Sheave Material | Q235B / Q345B forged steel (cast iron optional for light duty) |
| Groove Hardness | HRC 45–50 (induction hardened surface) |
| Groove Diameter | Matched to rope: e.g., Ø14mm rope → Ø250mm sheave (D/d ≥18 rule) |
| Bearing Type | Deep groove ball bearing (standard) / Tapered roller (≥32t) |
| Certification | ISO 9001, Hardness test report available |
What information is needed to select the right Crane Sheave (Pulley Block)?
Please share the required load, key dimensions, operating frequency, power supply and working environment. Drawings or site photos help us confirm the configuration.
Can the Crane Sheave (Pulley Block) be customized?
Yes. Dimensions, materials, speeds, controls and protection options can be matched to the project after technical review.
