Abstract
The top surface of an insert abuts with a form, with a tube extending into an aperture and sliding on a form post in the form. A rod inserted through the form, form post and tube holds the insert in place while castable material is poured in. The form is inverted with the guard rail base inside, the rod can be slid out of the form, and the form is removed. The handle is gripped by a claw on the obtuse angled chassis of a transporter. A handle on the chassis can be pushed to raise the guard rail base and to move the guard rail base on the surface by wheels. The guard rail base can be placed upon a pad having notches in its border.

Method comprising:
- providing an insert comprising a plate having a top surface and a bottom surface, a first tube extending through the plate and extending perpendicular to the top surface, a first handle fixed to the plate and extending from the top surface opposite to the bottom surface and spaced from the first tube, and an anchor fixed to the plate and spaced from the bottom surface opposite to the top surface, with the first tube having circular cross sections and configured to slideably receive a panel post of a panel, with the first tube including a lower opening extending through the tube parallel to the top surface and spaced from the bottom surface opposite to the top surface and a plurality of upper openings extending through the tube parallel to the top surface and spaced from the top surface opposite to the bottom surface, with the plurality of upper openings being circumferentially spaced around the tube, with the plurality of upper openings configured to slideably receive a pin to lock the panel post in the first tube;
- providing a form including an annular sidewall extending around a base, with the base including an aperture located within and spaced from the annular sidewall, with the annular sidewall including a form opening, with the form further including a first form post upstanding from a stand for the base and extending into and through the aperture, and with each form post including a post opening adjacent an upper end;
- sliding the first tube on the first post and abutting the top surface with the base around the aperture, with the first tube and the first handle extending through the aperture below the base;
- inserting a rod through the form, the post opening, and the lower opening of the first tube with opposite ends of the rod located outside of the form;
- filling the form with flowable castable material around the insert and the rod located in the form;
- after the castable material hardens in the form, inverting the form including hardened castable material and the insert, with the rod holding the hardened castable material in the form;
- after inverting the form, sliding the rod from the form, the hardened castable material and the insert;
- and
- after removing the rod, removing the form from the hardened castable material and the insert.
