Wood’s Powr-Grip's® Pad Frame T-Arm Assemblies increase the versatility of our MRT and MRTA series of below-the-hook vacuum lifters.

These plug-in style pad frame assemblies were specifically designed to enable MRT(A) vacuum lifters to handle insulated metal panels, cold storage panels and other cladding materials. By simply removing the standard pad arm extensions on existing vacuum lifters and replacing them with Pad Frame T-Arm Assemblies, you can transform MRT(A) lifters to handle cladding materials of various styles and dimensions.

The Pad Frame T-Arm Assemblies incorporate a T-shaped frame with a steel insert that fits inside the sockets on standard MRT(A) pad frames. An assembly is held firmly in place on the vacuum lifter through the use of a cotterless hitch pin, making installation fast and easy. Each side of the T-shaped assembly is equipped with an adjustable sliding pad mount, which can be secured in 9 different positions with another cotterless hitch pin. These sliding pad mounts support two specially designed vacuum pads, which can be selectively adjusted to conform to the load size or distance between contours. To make attachment to a lifter’s existing vacuum hoses quick and easy, each pad is equipped with a quick-connect vacuum fitting.

The Pad Frame T-Arm Assemblies feature a choice of vacuum pads: Model HV11F is equipped with closed cell foam rings, enabling attachment on archictectural panels and other materials with minimal surface relief. Model VPFS625 is designed specifically for cladding materials. The closed cell, EPDM foam rubber inserts (VIFS625) are UV resistant, chemical resistant and solvent resistant, and can be readily removed and replaced if they become worn or damaged. With dimensions of 6-1/2" x 25-1/2" [17 cm x 65 cm], these vacuum pads are ideally suited for attaching to high-relief insulated panels. (Please note that the VPFS625 vacuum pad is not suitable for use with single-skin metal panels, since it may result in surface distortion.) The narrow shape of this vacuum pad fits between large contours, and the foam rubber conforms to smaller contours and around surface irregularities, while still maintaining full vacuum and lifting function.

Because it imperative to keep the load balanced, two Pad Frame T-Arm Assemblies are required for each vacuum lifter. Pad Frame T-Arm Assemblies may be purchased as an option for new vacuum lifters or retrofitted to existing models, including the MRTA611LDC, MRTA8-DC, MRTALP611LDC, and MRT4-DC.
