A semi-electric stacker is a type of material handling equipment that combines manual and electric operation. It is designed to lift and transport heavy loads in a variety of applications, such as in warehouses, distribution centers, and manufacturing facilities.

The semi-electric stacker consists of a hydraulic pump, a mast, and a set of forks that are used to lift and transport loads. It is operated manually by a person, but it also has an electric motor to assist in lifting and lowering the load. The electric motor is powered by a rechargeable battery and is used to drive the hydraulic pump, which raises and lowers the mast and forks.

Semi-electric stackers are typically used in applications where a manual stacker is not powerful enough, but a full-powered forklift is not necessary. They are ideal for lifting and transporting loads to and from shelves, mezzanines, and other elevated surfaces. They offer greater lifting capacity than manual stackers and are easier to operate, but they are still compact and maneuverable, making them suitable for use in smaller spaces.

The advantages of a semi-electric stacker are that they are more powerful than manual stackers, but still more cost-effective than full-powered forklifts. They are also quieter and produce fewer emissions than full-powered forklifts. However, they have a lower lifting capacity compared to full-powered forklifts and are not suitable for lifting very heavy loads or for frequent use.
