The full electric hydraulic vehicle-mounted crane is a kind of hoisting equipment that integrates electric drive power and hydraulic transmission technology. Specifically, it refers to a device whose power source is completely derived from the vehicle-mounted battery (or an external power supply). It uses an electric motor to drive the hydraulic pump, generating high-pressure hydraulic oil, which in turn pushes the hydraulic cylinders and hydraulic motors to realize the telescoping, luffing, slewing of the crane arm and the execution of hoisting operations. It is usually installed on trucks, engineering vehicles, rescue vehicles and other types of vehicles, forming a mobile hoisting workstation. The operating noise of the electric motor is much lower than that of diesel engines, which greatly reduces noise pollution, making it suitable for noise-sensitive scenarios such as nighttime operations, residential areas and the vicinity of hospitals. With a compact structure, it requires minimal modification to the host vehicle and is easy to install. It is particularly suitable as an on-board tool for vehicles engaged in urban logistics, power maintenance, municipal engineering, small-scale installation, emergency rescue (such as wrecker trucks) and other operations.

The rated lifting capacity of such vehicle-mounted cranes ranges from 500 kilograms to 2 tons.
