Wall lift and method of lifting a wall

A wall lift for lifting a wall in an upright position comprising:

• a floor plate;
• a lifting arm receiver extending upward from said floor plate;
• a lifting arm rotatably attached to said lifting arm receiver, said lifting arm including a top and bottom;
• a pin at said bottom of said lifting arm about which said lifting arm rotates in said lifting arm receiver and wherein said lifting arm receiver includes at least one slot having an open end and a closed end and wherein said open end receives said pin and said closed end of said slot supports said pin;
• a motorized cable movement system attached to said lifting arm;
• a cable attached to said motorized cable movement system;
• and
• a wall movement unit for attachment to a top of said wall, said wall movement unit attached to and slidable along said lifting arm, said wall movement unit connected to said cable for movement of said wall movement unit by said motorized cable movement system and thereby lifting of said wall.

A method of lifting a prefabricated wall comprising:

• a. lifting a top of the wall so that the wall rotates about a bottom of the wall using a wall lift, said wall lift including
• a floor plate;
• a lifting arm rotatable attached to said floor plate, said lifting arm including a top and bottom, whereby said bottom is rotatable attached to said floor plate;
• said lifting arm being an elongated rectangular shaped tube including a rear face, a front face and two sides and said front face includes a continuous lengthwise opening along its center, thereby forming a track on each side of said opening;
• a motorized cable movement system attached to said lifting arm;
• a cable attached to said motorized cable movement system;
• a wall movement unit including a front plate and rear plate for lifting said wall, said wall movement unit attached to said lifting arm by sandwiching said tracks and opening between said front and rear plates, said front and rear plates slidable against said tracks of said lifting arm, said wall movement unit connected to said cable for movement of said wall movement unit by said motorized cable movement system and thereby lifting of said wall;
• b. using a lifting arm rotatably attached to a surface near the wall, said lifting arm including a motor and starting in a vertical position, said motor including a cable attached to a wall movement unit, and said wall movement unit attached to the top of said wall and also slidably attached to the lifting arm;
• c. allowing said lifting arm to rotate in the direction that the wall is being lifted as the motor retracts the cable;
• d. retracting the cable with said motor and pulling the wall movement unit towards a top of the lifting arm;
• and
• e. lifting the wall due to attachment of the wall movement unit to the top of the wall.
