The Weha Vacuum Lifter is a pneumatic vacuum powered lifting device. The device works by a suction effect created by compressed air and a specially designed rubber seal creating a tight bond. The company has created several models, designed for different applications.
Each of the Weha vacuum lifters is crafted from durable hot-dipped galvanized steel. This thick, protective coating creates a long-lasting, professional product. A vigorous inspection and testing process ensures the high quality of the device.
Crafted in Kongebrunn, Germany, the Weha Vacuum Lifter was designed for professional stonemasons. The device lifts a variety of materials including granite, polished granite, marble, rough stone, concrete, and steel. Textured, rough, and uneven surfaces are not problematic for the Weha Vacuum lifter. This makes it ideal for landscapers, monument makers, and contractors.
Models
The Weha EP series uses a single vacuum rubber seal measuring 28” x 10” and can easily lift hundreds of pounds. The steel body is designed to attach a crane or lift hook through the molded ring. The Weha EP is designed to lift up to 1300 pounds when attached to the material horizontally and up to 600 pounds with a vertical attachment point.
The EP series includes the 300/600/800 models. Each model comes with a large, specially designed Unipad seal which is easily replaceable as wear occurs. This vacuum rubber seal has a raised lip that creates a tight, long-lasting bond between the device and the stone material. The bond will hold for approximately one hour without fail.
Each model comes in three options for the consumer. For portability and use on a wide range of job sites, there is a hand pump only option. This model creates the vacuum seal through a push/pull pumping motion that builds up the air in the attached reservoir.
For ease of use, a second option includes the ability to attach to the air hose of a portable compressor through a pneumatic nipple. The compressor should have a maximum load of 2 cubic feet per minute at 60 psi. This allows the user to quickly refill the air reservoir as needed.
A third option on the EP series models includes both the hand pump and the compressor hookup. This gives the most versatility when considering job site use. This item has a higher price point but is worth the extra cost.
Cost/ Availability
Weha Vacuum lifters cost between $2000 -$5000, depending on the model and the retailer from whom you purchase the item. This may seem like an extreme price, but it is actually in the mid-price range compared to other vacuum lifters.
Weha Vacuum lifters are available at professional contractor supply stores in the United States and many other countries. Some stores have the items in stock, others will need to order the device and have it shipped.
Grabo Vacuum Suction Lifter
The GRABO Nemo is an electronic vacuum suction cup lifter designed for professional contractors. This lightweight, easy to use device easily replaces more expensive vacuum lifters and can save additional money on the jobsite by cutting down on the number of workers needed to do the job.
Designed for use on a variety of smooth and porous materials, the GRABO Nemo can lift up to 375 pounds of ceramic, glass, or stone tile. The patented, replaceable pad adheres to polished and rough stone, including rock and concrete. The easy one-handed operation gives you the ability to carry materials to the workspace and easily put them in place.
Specifications
The GRABO Nemo Suction Lifter is crafted from a high-end, durable plastic composite called PA6. This high tensile nylon polymer is specially designed and approved for power tools. The device weighs just 3.3 pounds, with the battery in place, and fits comfortably in the hand. The vacuum provides 11.6 psi of suction on most smooth surfaces. The 14.8V Lithium Ion battery charges in just two hours and holds a charge for 1.5 hours on non-stop running. The battery will last through 900 Off/On cycles.
Ease of Use
The GRABO Nemo is a single switch product. A simple on/off button engages the vacuum pump and a digital display notifies the user when the product has reached the desired pressure. The maximum vacuum rate is 11.6psi at 0.7cfm. The GRABO Nemo will hold up to 375 pounds in a horizontal position for up to 1.5 hours. Even if the battery goes dead, the suction will not release until the operator pushes the release button.
Convenience
The GRABO Nemo needs no additional air source and requires no manual pumping by workers. The battery operated electric motor creates a vacuum allowing the device to adhere securely to the material. There is no need for a compressor or air pump.
The battery charges in just 2 hours, and will cycle on and off over 900 times on a single charge. The patented lift pad is designed for use on smooth, polished, course, and porous surfaces and measures 11”x7”.
Availability/ Cost
The GRABO Nemo suction vacuum lifter costs in the $250 range, depending on the model and the retailer from whom you purchase the item. Buyers might be cautious because of the low cost, but the device has a proven track record of reliability.
The GRABO lifters are available at professional contractor supply stores in the United States and many other countries. Some stores have the items in stock, others will need to order the device and have it shipped.
