• disposing a linear cart on the linear slide-rail post, the linear cart having at least one roller disposed thereon for engaging and moving about the linear slide-rail post;
• and
• disposing a corner cart on the corner slide-rail post, the corner cart having at least one roller disposed thereon for engaging and moving about the corner slide-rail post.

An excavation support system, comprising:

• at least one linear slide-rail post;
• at least one corner slide-rail post;
• at least one slide-rail panel located between and in contact with the linear slide-rail post and the corner slide-rail post;
• at least one linear roller cart having at least one roller attached thereto, the linear roller cart adapted to slide onto the linear slide-rail post and secure thereto, wherein the linear roller cart is movable along an outer surface of the linear slide-rail post;
• at least one corner roller cart having at least one roller attached thereto, the corner roller cart adapted to slide onto the corner slide-rail post and secure thereto, wherein each corner roller cart is movable along an outer surface of the corner slide-rail post;
• and
• at least one hydraulic brace leg supported at one end thereof by the linear roller cart and at a second end thereof by the corner roller cart.
