A telescopic crane is a mobile lifting machine that features a boom comprised of multiple nested box sections that extend hydraulically to achieve greater reach without increasing the overall stowed length. This design allows the crane to be compact for transport and then expand to a long reach at the worksite. Telescopic cranes can be mounted on truck chassis (truck‑mounted cranes), on rail bogies (railway telescopic cranes), or on crawler tracks for rough terrain. The hydraulic extension system allows the operator to position the hook at any continuous distance within the boom’s range, providing precise placement for loads. Lifting capacities range from 10 tons for a small service crane to over 500 tons for large all‑terrain models. The telecopic boom may include a secondary swing‑away jib to extend reach even further, and some models incorporate a “fly jib” for working at high elevations. Telescopic cranes are used in construction for placing steel beams, in utility work for lifting transformers onto poles, and in shipyards for handling components deep inside vessels. Modern telescopic cranes feature load moment indicators that warn of impending overload based on boom angle and extension length, and they incorporate outriggers to stabilize the base during lifts. Because each telescopic crane job site has different reach, capacity, and mobility requirements, we recommend a thorough needs analysis.
