Adjustment blocks allow incremental adjustments for different sized sewing machines.
These are the same German-made lifts that others were selling for much more. Our Amish hardware distributor has made special arrangements with the German company and buys them by the container loads for Amish sewing cabinet builders. We can offer them to others wanting to build sewing cabinets and we have them in stock while others can no longer get them.
Overall height is 22-1/2" x 11" Deep x 12-3/4" wide, with a maxim lift travel of 16-1/2". Hole spacing for mounting is 8-1/4" center-to-center top horizontal angle bracket and 6-3/4" center-to-center bottom horizontal angle bracket. The vertical distance to the centerline in the top and bottom horizontal mounting bracket holes is then 20-7/8". The distance from the back of the lift where it will mount against the back of the cabinet to the front of the "Y" brackets is 11" and from the front of the lift out to the end of the "Y" brackets for the sewing machine shelf is 8-1/2".
The sewing machine shelf "Y" brackets are 12-1/2" outside tip to outside tip. The sewing machine shelf that will attach to the sewing lift "Y" brackets should be the same thickness of the sewing cabinet top and can be cut to fit all sizes of sewing machines. The minimum size shelf to cover the "Y" brackets will be 12-1/2" wide x 8" deep if being used on a small machine such as a serger. Regardless of the size, the sewing machine should sit as much to the center of the sewing lift "Y" brackets so as not to cause undue leverage on the roller carriage assembly when pushing down to release the machine. In other words, if the lift is being used in a retrofitted deep desk more than 20" deep a platform back extension should be built to mount the lift forward in the cabinet to make up the difference instead of attempting to build a deeper sewing machine shelf and having the sewing machine sitting out in front of the "Y" brackets.
We receive numerous calls regarding retrofitting one of these lifts into a vintage sewing cabinet specifically built for sewing machines using head hinge pins to fold the machine down into the cabinet. Those cabinets were not built with a substantial sized back or depth to utilize the air machine lift mechanism.
We also carry the original heavy-duty up to 50 lb. airlift. Click Here for more information
Two fast taps pushing down just like bouncing a basketball close to the floor releases the lift. Adjustable set screws lockdown once the machine settings are determined. If you plan on using the lift for an additional machine simply add a block of wood the thickness needed to adjust between machines without having to readjust settings each time.
Please note: It is difficult to manufacture a universal sewing lift for all the different weights of sewing machines. The stated capacity is the maximum weight that should be used on the lift. If you use a lighter weight machine it may require a little more effort to push the machine down into storage position, but it should come up quite easily. If it is a heavy machine it will be easier to lower but you may need to assist the lift to raise the machine over the last inch or two to raise on up to the sewing bed height or the tabletop height.
Attaches with six #8 wood screws for installation. (Not Included) The lift will require at least 3/4" blocking or solid surface.
