A multi-section hydraulic boom that extends and retracts to adjust the crane's reach and lifting height.
Technical details and manufacturing context for Telescopic Boom
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Rated Lifting Capacity | 5–50 t | At minimum boom length; derates as boom extends.ISO 4305 |
| Maximum Boom Length | 10–60 m | Fully extended length; affects reach and height. |
| Boom Sections | 3–6 | More sections allow longer retracted length for transport. |
| Extension Time | 20–90 s | Full extension time; affects cycle time. |
| Retraction Time | 15–70 s | Full retraction time; affects cycle time. |
| Operating Pressure | 20–35 MPa | Below 20 MPa may not lift rated load. |
| Boom Material Grade | Q345B–Q960E | Higher grade for longer booms or higher capacity.GB/T 1591 |
| Operating Temperature Range | -20–+50 °C | Below -20°C may require special steel and seals. |
| Maximum Wind Speed | 9.8–14.1 m/s | Above this, operation must stop to prevent tipping.ISO 4302 |
| Weight | 1.5–8.5 t | Boom assembly weight; affects crane stability and transport. |

A telescopic boom is a load-bearing component of a crane that extends and retracts to adjust the crane's reach and lifting height. It is commonly used on rough terrain cranes to position loads in challenging off-road environments.
The boom consists of nested steel sections that slide within each other. Hydraulic cylinders push and pull the sections to extend or retract the boom. Locking mechanisms secure the sections at the desired length during operation.
Typical parameters include rated lifting capacity of 5-50 t, maximum boom length of 10-60 m, 3-6 boom sections, extension time of 20-90 s, retraction time of 15-70 s, operating pressure of 20-35 MPa, material grade Q345B-Q960E, operating temperature -20 to +50 °C, maximum wind speed 9.8-14.1 m/s, and weight 1.5-8.5 t. These are reference ranges; verify for the specific model.
Standards such as ISO 4305 (rated lifting capacity) and ISO 4302 (wind speed) may be referenced. However, compliance must be verified with the legal manufacturer or supplier for the specific boom model.
