A tongue jack includes a drive screw and a lifting assembly coupled with the drive screw. A first bevel gear is secured to the drive screw with a rotation axis aligned with a rotation axis of the drive screw. A second bevel gear engages the first bevel gear with a rotation axis perpendicular to the rotation axis of the first bevel gear. A drive head is connected to the second bevel gear, and a coupler is selectively engageable with and disengageable from the drive head. A handle assembly may be connected to the coupler that is rotatable about the rotation axis of the second bevel gear, where the handle assembly includes a crank handle spaced from and parallel to the rotation axis of the second bevel gear.
