           Vacuum stone lifters with pneumatic motions system, vacuum gripping system and safety protection system are designed as one kind of flexible lifting equipments mainly used for gripping, lifting, moving and placing materials, which work in a semi-automatic way. Also can these lifters provide vacuum automatic compensation system for  working safety and convenience and are suitable for lifting and handling glass, marble, plastic boards, metal sheets, steel boards, aluminum boards, coated boards and other plates. Besides, vacuum stone lifters driven by battery have the advantage of holding for a longer time thanks to their great flexibility and unique technology, while other common lifters cannot lessen labor and increase productivity to a great degree.

           This series stone vacuum lifter is mainly designed for stone handling in workshop use. We provide two different types of handle machines: Air powered  lifters are used for marbles and granite cutting machines are applied for feeding and unloading. As for quartz stone demolds, we would offer electric lifters for higher stability.

           When using vacuum stone lifters, please turn the power switch to the working position and the meter will display the battery content. When the battery is low, please do not use the lifter. The compressed air switch is opened to "through", the injector starts to run, and the vacuum hand slide is kept in the "release" position, waiting until the pointer of the vacuum meter reaches the green area, which indicates that the vacuum system preserves enough vacuum and prepares for the work. The load pad is placed on the load surface to ensure that the spring buffer of all the gaskets is compressed, and all the suction pads are fully connected to the load. When the vacuum pressure reaches to the required vacuum, the vacuum manual slide valve is pushed to the "inhalation" position.

           Vacuum stone lifters are also called vacuum slab lifters, stone lifting machines, electrical stone vacuum lifters, slab vacuum lifters, stone vacuum lifters, heavy duty stone lifters, granite lifting equipments, granite vacuum lifters, slab lifter equipments, vacuum lifters for granite slabs, vacuum lifters for marble slabs, vacuum lifter versatile pneumatic, vacuum lifter slim pneumatic, vacuum lifters for stone slabs, stone products vacuum lifter, stone handling vacuum lifters, vacuum paving stone lifter, pneumatic vacuum lifters for slabs.

          They are widely applied for lifting,  gripping, moving, placing and installing a large-size smooth or rough slab, and some situations where other types of lifters would fail, particularly through heavy industries such as plastic boards, ceramic plates, sheet metals, coated boards, steel boards, aluminium boards, stones slabs and laminated chipboards. They are also ideal vacuum stone lifting equipments for materials with different sizes and shapes such as table tops, sinks, clippings and marble shops or service providers in the works because of their adjustable structures which provide more flexibility in the movement.

1.Vacuum tank
           The vacuum tank is driven by the swirling rod body, which keeps the plunger moving in and over the air chamber. The gas in the tank enters the air chamber by the air hole and is discharged by the valve hole. And by restoring the original shape of the plunger by the elastic element, the lever can be operated with the lever and the air is pumped efficiently. So when the power fail suddenly, the pad always can holding the sheet instead of falling down less than 30 minutes and more.
 2.Buzzer and warning light units 
           Buzzer is an integrated structure of electronic signal, using DC voltage power supply, widely used in computers, printers, copiers, alarm devices and other electronic products as sound devices. Buzzer is mainly divided into two types: piezoelectric buzzer and electromagnetic buzzer and the buzzer uses the letter "H" or  "HA" in the circuit. In case of a power failure or vacuum leakage, warning unit can control the red warning lights on, At the same time a buzzer sounded, which prompts operator treatment in time. 

3.Vacuum pressure switch
           The vacuum switch is a kind of switch that detects the vacuum range and also known as the vacuum relay. The function is that when the vacuum degree produced in the actual work reaches the required conditions, the control circuit is automatically opened and closed, the electrical signal is issued, and the normal action of the vacuum adsorption mechanism is ordered. To detect the vacuum level, the switch control the vacuum’s starting and stopping points for power save.

4.Suction pad | Adjustable pad
           A variety of suction pads made of sucker can be operated at high temperature. The pad made from silicone rubber is very suitable for grasping the rough surface. What’s more, the pad made of polyurethane is very durable. It is widely used in various vacuum suction equipment, such as in the building, paper industry and printing, glass and other industries, to carry out and carry thin and light items such as glass and paper.

5.Ball valve
           The ball valve controls pad in individually and each suction pads are equipped with manual ball valve which can ensure a same equipment and handle various specifications plate. The ball valve is simple in structure, easy in position installation and convenient in loading and unloading, and does not change position due to vibration during use. It reduces time and increases economic benefits greatly. There are two kinds of billiard valves: jujube core and square. The square can be made into detachable, easy to repair and maintain, and reduce production cost. The  product has been pressurized before the factory testing, and its air tightness has reached the national industry standard.

6.Air cylinder
           The air cylinder is a cylindrical metal part which guides the piston to move straight and reciprocally in the cylinder. The air is transformed into mechanical energy through expansion in the engine cylinder, and the gas is compressed by the piston in the compressor cylinder to increase the pressure.

7.Spring cushion
           The spring cushion mainly consists of bumper, spring and shell. Its characteristic is that the mechanism is simple and the use is reliable. When the Vacuum stone lifters hits the spring buffer, its energy mainly changes to the compression energy of the spring. The improved spring buffer with stop mechanism can prevent rebound. The structure and maintenance of the spring buffer are relatively simple, and there is no special requirement  for working temperature. What’s more, suction pads are equipped with a spring cushion. When the plate is uneven, the spring effects buffer action and makes the suction pad strength evenly, so as to ensure suction and lifter safely and stably.
