Any lifting machinery that integrates vacuum as a part of the lifting mechanism is known as vacuum lifters. They include a below-the-hook frame with a huge vacuum pad or numerous minor suction cups for gripping large sheets, rolls, plates, or other smooth-surfaced products. They are driven by pneumatic, hydraulic, electric, or mechanical power. The vacuum lifter is the part of the vacuum lifter that comes in close contact with the weight to be lifted. Each part of the vacuum lifter are made up of numerous part that come together to form the vacuum lifter, and they are;
Vacuum generators: the vacuum generator is the part of the plate lifter that assists the plate lifter by contributing the necessary vacuum. The vacuum generator can either function electrically or pneumatically. Pneumatic generators assist in attaining small and speedy cycle rotation. These vacuum generators can be attached straight into the system owing to their lightweight and solid design. Electric generators are made used if extraordinary suction capacity is necessary or there is no accessibility to compressed air.
Compressed air: compressed air is used by the vacuum generator to generate a vacuum.
Hoses: The special vacuum hoses are used together with the vacuum suction cups to meet the range of the cups and the capacity of the stream that is needed.
Fittings: silencers, ejectors, vacuum filters, vacuum regulators are fittings that commonly complement vacuum suction cups to support heightened performance.
Valves: Valves assists the vacuum suction cups by regulating the vacuum and the movement of
Types of Vacuum Lifters
There are many diverse kinds of vacuum lifter plates. The different types of vacuum lifter plate include heavy-duty lifters, vertical-horizontal lifters, twirl lifters, battery-powered vacuum lifters, and products with mobile attachments.
Heavy-duty vacuum lifters are produced with huge lifting frames, vacuum pads, and vacuum stations. They are designed to lift weight, such as metal plates.
Vertical-horizontal lifters can hold a weight in position, whether vertically or horizontally, depending on the weight requirement.
Twirl lifters are vacuum lifters designed for handling weight with rolls and coils.
Battery-powered vacuum lifters are comparable to electrically powered devices, but instead of being powered electrically, they are powered by a rechargeable battery.
Mobile attachment vacuum lifters are the perfect fit for use with forklifts, diggers, and other end- effector equipment.
Vacuum lifters can operate using four different types of driving mechanisms:
pneumatic, hydraulic, electric, or mechanical power. Pneumatic or air-powered vacuum lifters are equipped with air cylinders or motors that offer lifting action. Hydraulic vacuum lifts are powered by an external hydraulic cylinder or hydraulic motor. Electric-powered vacuum lifters have an electric motor and feature a screw/scissor combination. Mechanical or self-powered vacuum lifters that do not require electrical or compressed air service are also available.
When purchasing a vacuum lifter plate, it is important to carry out proper research to inform your choices to select the perfect vacuum lifter plate for the type of weight you intend to lift. The following procedure is recommended for vacuum lifter selection:
Identify the size of the material to be lifted
Determine the minimum and maximum dimensions and maximum weight of the load. The minimum and maximum thickness are also critical. Furthermore, define the quantity of acceptable load overhang. Overhang and layout among pads are based on the minimum thickness of material or weight to be lifted. The tinniest material to be lifted has the highest refraction and should always be measured when determining the permissible overhang by the vacuum lifter plate.
Determine the number of pads Lengthwise and row-wise
By making use of the applicable table, define the minimum number of pads required for the maximum load length and approximate it up to the succeeding highest number. For example, if the maximum stretch is 180 inches (4.57 m) and the proposed spacing between pads is 90 inches (2.29 m), use a lifter with a minimum of two cups (180/90=2). Decide the minimum number of lifting pads required for the maximum load length by dividing the maximum load length by 2L and approximate it to the subsequent highest number.
Choose the lowest number of lifting pads essential for the maximum load width by dividing the maximum load width by the 2L number from the table and approximating it to the subsequent the highest number. For instance, a load width of 72 inches (1.83 m) with a recommended spacing between pads of 60 inches (72/60=1.2: rounded up to 2) needs at least a minimum of two pads along the width of the load.
Determine the beam length
The beam length is calculated by deducting 2L from the maximum load length, then adding 6 inches (ca. 15 cm) to it. For instance, with a maximum load length of 120 inches (ca. 3 m) with a 2L of 60 inches (1.52 m), the minimum beam length would be 66 inches (120-60+6). If this is not a standard length, select the next longest standard beam length.
It is important that when selecting vacuum pads, make use of the smallest number of pads needed; use pads with the largest possible length, the weight of the load should never surpass five times the lifting pad width or diameter when handling a weight with a single row of pads. Pad capabilities must be measured by 50% when used for vertical handling or toppling (tilting) applications. Also, unbendable weight such as glass should be clasped nearly flat and for other weight material such as wood, particleboard, etc. Deflection can be estimated by direct measure.
While numerous rows may not be necessary when using the above guidelines, they should be considered if load tilting is a concern. When selecting the number of cross arm members on a vacuum lifter designed for up-ending (tilting), an even number of cross arms must be quantified to avert intrusion with the up-ending yoke. It is important to patronize a reliable manufacturer that will put you through every instruction you need to know about your vacuum plate lifter to get a good run for your money.
