Overview
Vacuum hose lifters are a highly efficient and energy-saving solution designed for handling cardboard boxes. Utilizing a single vacuum source, they achieve both “adsorption” and “lifting” functions, significantly reducing the labor intensity of manual handling.
The vacuum hose lifter uses the negative pressure generated by a vacuum pump to cause the lifting hose to shorten or extend like a spring, thus enabling the vertical lifting and lowering of goods. A single handle allows for easy suction, lifting, lowering, and release, making it an ideal choice for ergonomic handling.
Core Working Principle
The core of the vacuum tube lifter lies in its telescopic vacuum tube.
- Adsorption: When the suction cup contacts the surface of an object, the vacuum fan generates negative pressure, firmly gripping the object.
- Lifting: As the vacuum level increases, the vacuum lifting tube contracts due to the internal pressure being lower than the external atmospheric pressure (similar to the rebound of a spring), thus lifting the load.
- Lowering and Releasing: By controlling the depressurization valve with an operating lever, the vacuum level inside the tube is reduced. The lifting tube extends under gravity, lowering the object. When the pressure is completely released, the suction cup automatically releases the object.
Main Advantages of the Product
- High Efficiency and Labor Saving: Operators require minimal force to control loads of hundreds of kilograms, significantly reducing labor intensity.
- Non-Destructive Handling: Utilizing rubber or silicone suction cups, it will not scratch workpiece surfaces (such as packaging boxes, stainless steel plates, and glass).
- High Safety: Equipped with power failure protection. In the event of a sudden power outage, the one-way valve locks the vacuum, causing the object to descend slowly rather than fall instantly.
- Intuitive Operation: Lifting, lowering, suction, and release are all integrated into a single control handle, allowing for one-handed operation.
- Extremely High Frequency: Compared to electric hoists, vacuum tube lifters have extremely high cycle speeds, making them particularly suitable for high-frequency, short-distance handling operations.
