A forward moving powered cart configured to receive a bundle of roof decking sheets, and which cart rides on the each of three spaced adjacent trusses after being crane lifted onto the said roof trusses. The cart has two sets of spaced casters that ride on the 1st and 3rd truss, while a safety truck on the cart designed to prevent slippage from the two trusses upon which its two sets of casters ride, engages the middle truss of the three. Sheets are removed from the rear for placement and post installation, the cart is moved forwardly an incremental amount.
