Self-absorbing (non-powered)Introduction to the vacuum lifterApplication fields and characteristics:Lishizhi produces non-powered vacuum liftersIt is a green energy-saving product that does not require a vacuum pump or compressed air, automatically generates vacuum, operates silently, and is pollution-free. It can lift steel plates, oil drums, molds, and non-metallic plates such as stainless steel plates, copper plates, aluminum plates, insulating boards, glass, floor tiles, marble, and granite that cannot be lifted by electromagnetic suction cups. The non-powered vacuum lifter produced by the company is also called a self-absorbing vacuum lifter, and the entire vacuum equipment does not require a power source, external control, or other complex accessories. Working principle: A free-moving piston is inside a closed cylinder, and a rubber rolling membrane forms a seal between the piston and the cylinder. This seal does not rely on contact and tight fit between metals and continuously functions as a seal during the operation of the equipment. This product has a reasonable design, a wide range of applications, and reduces usage costs, making it a very practical self-absorbing lifting device.Design and function:
- Modular design vacuum crane with a piston system, non-powered control
- Adjusts the vacuum on/off through the lifting/lowering motion of the chain hoist
- Aluminum main beam with integrated vacuum diverter (load up to 750Kg)
- Battery alarm device has battery detection function and issues an alarm when vacuum level drops
- Vacuum suction cups are easy to adjust
Customer benefits:- Soft and safe vacuum handling
- No need for additional power supply, flexible application
- Quick installation and operation
- Saves operating costs

Non-powered suction cranes represent an innovative solution for lifting and transporting smooth-surfaced materials without relying on electricity, hydraulics, or compressed air. These mechanical systems utilize vacuum generation through purely physical means, typically employing manual pumps or lever-operated mechanisms to create the necessary pressure differential. The core technology relies on self-sealing suction cups made from high-grade elastomers that conform to surfaces upon contact, with industrial models achieving holding capacities up to 150kg per cup through optimized cup geometry and durometer ratings. When properly engaged, these systems maintain vacuum integrity through one-way valves that prevent air backflow, allowing continuous load handling until manual release.
The operational principle centers on mechanical advantage - a hand-operated plunger or rotary pump evacuates air from the suction chamber with a 5:1 to 10:1 force multiplication ratio. High-performance models incorporate dual-stage pumping mechanisms that can achieve 80% vacuum levels (approximately -80kPa) within 3-5 strokes, sufficient for lifting polished stone slabs, glass panels, or metal sheets. The suction cups feature reinforced brim designs that distribute load stresses evenly, with textured inner surfaces that minimize vacuum leakage across minor surface imperfections up to 0.3mm deep. Safety mechanisms include automatic pressure relief valves that engage at 120% of rated capacity and visual vacuum indicators that show seal integrity through colored markers.
