This page explains how Luffing Jib Crane is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
A tower crane with a jib that can be raised or lowered to adjust its working radius.
Technical details and manufacturing context for Luffing Jib Crane
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Maximum Lifting CapacityRequired | 8–64 metric tons | The maximum safe working load the crane can lift at its minimum radius. |
| Maximum Jib LengthRequired | 30–80 meters | The fully extended length of the jib from the tower center. |
| Maximum Working RadiusRequired | 25–70 meters | The maximum horizontal distance from the tower center to the hook at minimum jib angle. |
| Minimum Working RadiusRequired | 2.5–4.5 meters | The minimum horizontal distance from the tower center to the hook at maximum jib angle. |
| Maximum Hook HeightRequired | 40–100 meters | The maximum vertical distance from ground level to the hook. |
| Slewing Speed | 0–0.8 rpm | The rotational speed of the jib around the tower. |
| Hoisting Speed | 0–60 m/min | The speed at which the hook raises or lowers a load. |
| Luffing Speed | 0–30 deg/sec | The angular speed at which the jib raises or lowers. |
| Operating Temperature Range | -20–40 °C | Below -20°C use low-temperature steel. |

CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The luffing jib can be raised or lowered to change the working radius, allowing operation in confined spaces or when multiple cranes work close together, as the jib can be angled to avoid interference.
Typical maximum lifting capacity ranges from 8 to 64 metric tons, with maximum jib length from 30 to 80 meters. Maximum working radius is 25 to 70 meters, and minimum radius is 2.5 to 4.5 meters. These values vary by model and must be confirmed with the manufacturer.
Load moment limiters and anti-collision systems monitor stability and prevent overloading or collisions. Additionally, wind speed sensors may be used to ensure operation within the maximum wind speed of 20 m/s.
The operating temperature range is -20°C to 40°C; below -20°C, low-temperature steel is required. The crane must be secured if wind speed exceeds 20 m/s. Always verify specific environmental limits with the manufacturer.
