Form follows function: The new vacuum lifting device VacuMaster HHVM

Schmalz presents the new generation of the VacuMaster HHVM. The vacuum lifting device is lighter and more economical than ever and increases efficiency when handling raw and coated wooden boards.

With the new vacuum lifting device VacuMaster HHVM from Schmalz, the slim form follows the function. Thanks to the lifting device’s compact dimensions, the user can pick up wooden boards from narrow, upright storage containers, swivel them by 90 degrees as needed, and load them into either a horizontal or a vertical panel dividing saw. The compact design of the HHVM also offers ergonomic benefits and increases operating comfort.

Slim figure
With an overall height of only 270 millimeters in the swiveling position, the VacuMaster HHVM is no larger than a sheet of A4 paper and weighs a maximum of 60 kg. All of the functional elements are placed lengthwise on a robust aluminum beam. This beam also serves as a vacuum reservoir, which increases operational reliability and shortens pick-up times. The ergonomic operator handle is located on the front side of the device. This handle allows the user to control the load and move it safely. The easy-to-move pivot bearing sits in the middle. The user can unlock the pneumatic latch bolt with the press of a finger and can then easily swivel the lifting device along with the board being transported to the left or to the right. The flat basic module at the end of the device contains the powerful ejector for vacuum generation. A pressure reduction valve continuously provides the correct input pressure. The user can get information about the system vacuum at any time from the gauge. In the case of an impending drop in vacuum, an electronic warning device alerts the user early on. The suction plates (four, six or eight suction plates, as needed) are arranged in an offset pattern and can be switched off individually or in pairs. This makes the device flexible enough to adjust to boards with various dimensions and cut pieces.

30 percent lower energy consumption
As compared to the previous model, Schmalz has reduced the HHVM’s compressed air consumption by over 30 percent. These savings are the result of the use of a more efficient ejector. The standard air-saving control, a kind of start-stop function for the vacuum generator, saves even more energy. Once a safe vacuum level has been reach, the ejector automatically shuts off and only turns back on in the case of an impending drop in pressure.

The VacuMaster HHVM is now available. Three load classes for 100, 150 and 200 kg are available. The specified maximum load is achieved with a system vacuum of just 200 mbar, allowing even porous particle boards and MDF sheets can be held securely. For commissioning, the device only needs to be installed on the chain hoist and connected to an existing compressed air supply.
