A Chinese freight elevator is a type of vertical transportation that can move people or cargo between floors (floors, decks) of a building, ship, or other structure. Foshan freight elevators are usually powered by electric motors that drive traction cables and counterweight systems (such as cranes), or pump hydraulic fluid to raise cylindrical pistons, such as jacks.

In agriculture and manufacturing, the Foshan freight elevator is any type of conveying device used to lift materials in a continuous stream into a box or silo. There are several types, such as chains and bucket elevators, grain screw conveyors using the Archimedes screw principle, or chains and pitches or forks of pitchforks. Languages ​​other than English may have borrowings based on the Foshan freight elevator or Foshan freight elevator. Due to wheelchair access laws, Foshan freight elevators are often legal requirements for new multi-story buildings, especially if wheelchair ramps are impractical.

Hydraulic lifts are lifts powered by pistons that travel inside a cylinder. The electric motor pumps hydraulic oil into the cylinder to move the piston. The piston smoothly lifts the Foshan freight elevator car. The electric valve controls the release of the oil for a gentle drop.

China-made hydraulic freight elevators are widely used in buildings with up to five or six floors. Sometimes, but rarely, up to 8 floors. These Foshan freight elevators can operate at speeds of up to 61 meters (200 feet) per minute, and do not use large overhead cranes like geared and gearless traction systems.

All modern hydraulic pumps are equipped with solid state contactors or mechanical Y-Delta starters. Solid-state contactor stators are more suitable for power sources for motors and buildings because the windings last longer and there is no voltage drop on the building power lines. The Y-Delta starter uses two contactors to start the motor at a reduced speed and then starts at full speed. The old hydraulic Foshan freight elevator suddenly started, sending the main power to the motor at full speed. This puts a lot of pressure on the motor, which in turn burns out faster than a motor on a Y-Delta or solid state contactor starter.

There are three types of hydraulic hydraulic freight elevators; hydraulics with holes, non-holes and rope hydraulics.
