Abstract
A tie rod puller including a pull housing, a clutch assembly and a clutch assembly housing is disclosed. The tie rod puller accelerates the process of pulling tie rods and installing key plates. The pulling of tie rods better secures the panels of a structure under construction to improve the integrity of a structure. The clutch assembly movably rotates a nut as a tie rod is being installed. The clutch assembly includes a stopper to prevent the nut from moving too far back. The clutch assembly is to hold and move a tie rod upon pulling of the tie rod and installing a key plate onto a wall. The clutch assembly housing includes a plate, which receives a key plate with a magnet. The plate includes brackets to stabilize the tie rod puller. The tie rod puller is preferably operated by automatic means such as by an impact drill.
