A telescopic crane has a boom that consists of a number of tubes fitted one inside the other. A hydraulic or other powered mechanism extends or retracts the tubes to increase or decrease the total length of the boom. These types of booms are often used for short term construction projects, rescue jobs, lifting boats in and out of the water, etc. The relative compactness of telescopic booms make them adaptable for many mobile applications.
Telescopic cranes have tubes that fit one inside another. Imagine a telescope used by a sailor long ago. The boom of the crane slides in and out of itself just like the telescope. Telescopic cranes can reach much farther than regular mobile cranes. They can also become very small. When they arc small, they are easy to move from place to place.
Note that while telescopic cranes are not automatically mobile cranes, many of them are. These are often truck-mounted.
