Abstract
A truss lifter and stabilizer that allows a single individual to install, lift and secure trusses. The truss lifter and stabilizer is installed to an already secured truss. Then a new truss is attached to the truss lifter and stabilizer and lifted into place. The loose attachment of the first cleat allows the user to manipulate the truss while still attached to the truss lifter and stabilizer to correctly position the truss for installation. The truss is then secured to the structure. The process is repeated until all of the trusses have been lifted and secured to the structure.
Description
- The present invention is a truss lifter and stabilizer that is capable of loosely attaching to the frame construction of a building such as a house, garage or pole barn. The truss lifter and stabilizer is attached to the frame structure and lifts a truss into place for securement of that truss to the frame structure.
- The truss lifter and stabilizer is capable of being quickly installed to lift a truss and then just as quickly being removed and secured to an existing truss once which allows for lifting the next truss into place. It has been discovered that the loose attachment allows the truss lifter and stabilizer to be manipulated in order to place each new truss in its correct position. It has also been discovered that the simplicity of the present invention allows the device to be placed and operated by a single individual. This aspect alone gives the device a greater utility over any prior art device.

- The present invention is a truss lifter and stabilizer. The truss lifter and stabilizer is comprised of a main vertical mast that has a near end, a distal end, a front side and a back side.
- The truss lifter and stabilizer has a first cleat that is rigidly affixed to the back side of the vertical mast near the near end and a retrieval system fixedly attached to the front side near the near end.
- The truss lifter and stabilizer has a primary horizontal strut mounted on the front side and near the distal end. The primary horizontal strut has a bottom surface. The primary horizontal strut has a brace extending from the primary horizontal strut to the vertical mast.
- This brace is rigidly affixed to the primary horizontal strut and the vertical mast.
- The strut has at least two guide pulleys mounted on the bottom surface. Also present is a crown cleat mounted on the back surface and near the distal end, the crown cleat configured to fit a peak of a truss.

FIG. 1 shows a full side view of the truss lifter and stabilizer of the present invention. -
FIG. 2 shows a full back view of a crown cleat. -
FIG. 3 shows a full side view of a bottom cleat attached to a portion of the mast. -
FIG. 4 shows the truss lifter and stabilizer installed on a frame structure. -
FIG. 5 is an expanded area ofFIG. 4 showing the first cleat and the frame construction. -
FIG. 1 shows a full side view of the truss lifter andstabilizer 2 of the present invention. Thevertical mast 4 has anear end 6 and adistal end 8. Thevertical mast 4 of the present invention also has afront side 10 and aback side 12. Thefirst cleat 14 is mounted on thevertical mast 4 near thenear end 10 on theback side 12. Near thedistal end 8 of thevertical mast 4 is asecond cleat 16. At thedistal end 8 of thevertical mast 4 is ahorizontal strut 20. Thishorizontal strut 20 has anear end 32 and a distal end 34 as well as a bottom surface 22. Thedistal end 8 of thevertical mast 4 and thenear end 32 of thehorizontal strut 20 are joined and supported by abrace 24. - The
retrieval system 18 of the truss lifter andstabilizer 2 is located on thefront 10 of thevertical mast 4. Theretrieval system 18 consists of ahand crank 36, at least afirst pulley 26, asecond pulley 28 and anattachment point 40 at the end of theretrieval system cable 42. -
FIG. 2 shows the crown cleat orsecond cleat 16 from the back. This cleat is mounted to theback surface 12 of thevertical mast 4. This feature is critical to the utility of the invention, in that, thesecond cleat 16 sits on the peak of the last truss that was place on the frame structure 44 (shown inFIG. 4 ) and secured on theframe structure 44. Once a truss 46 (shown inFIG. 4 ) is secured the truss lifter andstabilizer 2 is attached to thattruss 46 and anew truss 46 is lifted into place to be secured. Thebottom surface 38 of thesecond cleat 16 is configured to accept thepeak 48 of atruss 46. -
FIG. 3 shows thebottom cleat 14 from the side. Thiscleat 14 is also critical to the utility of the truss lifter andstabilizer 2, in that, it fits over the bottom member of a truss 46 (shown inFIG. 4 ), but does so loosely. This loose fit gives the operator the capability of moving the truss lifter andstabilizer 2, as well as thetruss 46, to get the alignment for the installation to theframe structure 44. Thebottom cleat 14 is attached to thebackside 12 of thevertical mast 4. Thecleat 14 resembles an L bracket and with its attachment to thevertical mast 4 it keeps the truss lifter andstabilizer 2 from kicking out and away during the lifting process. -
FIG. 4 shows the truss lifter andstabilizer 2 installed on aframe structure 44. It has been discovered that the dimensional construction of the truss lifter and it keeps the truss lifter andstabilizer 2 from kicking out and away during the lifting process. -
FIG. 4 shows the truss lifter andstabilizer 2 installed on aframe structure 44. It has been discovered that the dimensional construction of the truss lifter andstabilizer 2 is such that when it is attached to thelast truss 46 that was secured to theframe structure 44, and deployed, it lifts thenext truss 46 almost exactly where it is required to be installed on theframe structure 44. - The operator must attach the truss lifter and
stabilizer 2 to an existingtruss 46. Once the truss lifter andstabilizer 2 is secured, thecable 42 is guided out of theretrieval system 18 and attached to thetruss 46 at itspeak 48 atattachment point 40 of thecable 42. Once thetruss 46 is secured to theattachment point 40 theretrieval system 18 is activated raising thetruss 46 off of the ground and up to the level of theframe construction 44 where it is to be attached to theframe construction 44. Thetruss 46 is manipulated into place then it is secured to theframe construction 44. Once thetruss 46 is secured to theframe construction 44 the truss lifter andstabilizer 2 is removed from theprevious truss 46 and attached to thenewest truss 46 and the process starts over. The process is repeated until all of thetrusses 46 have been lifted and secured to theframe construction 44. - From this figure it is clear that the truss lifter and stabilizer is secured to the top 50 of the
frame construction 44. Also visible is theside 52 and bottom 54 of theframe construction 44. - The truss lifter and
stabilizer 2 is capable of being installed by a single person and then used by a single person. This makes the construction of a building of frame construction possible by a single person. These operations ordinarily require more than one person. A single individual is now capable of building a house, pole barn or garage without the assistance of any other person. The cost is thus cut in half. -
FIG. 5 is an expanded view of the circular area ofFIG. 4 . This figure features a closer view offirst cleat 14 and its attachment to the top 50 of theframe construction 44. It is clear that thefirst cleat 14 encompasses the top 50 as well as theside 52 of theframe construction 44.
