A trolley includes a body and a side block coupled to the body via a pivot arm and a spring. An adjustment knob adjusts a position of the side block relative to the body. A first plurality of rollers are coupled to the body and roll along a first roller recess on a first side of a length of a cap channel. A second plurality of rollers are coupled to the side block and roll along a second roller recess on a second side of the length of the cap channel. A first welding torch bracket positions a welding torch at a first interface between the first side of the length of the cap channel and a first deck sheet as the trolley traverses the length of the cap channel.

An internal floating roof for a storage tank includes a rim, a first plurality of girders, including a first girder, a second plurality of girders, including a second girder, a deck sheet, a first cap channel, a second cap channel, and a pontoon coupled to the first girder. The first plurality of girders extend in a first direction across the rim, wherein the first plurality of girders comprises a first girder. The second plurality of girders extend in a second direction, cross-wise to the first direction. The deck sheet is disposed on a first top surface of the first girder and a second top surface of the second girder. The first cap channel is coupled to a first top channel of the first girder. The first cap channel comprises a first foot configured to press a first edge of the deck sheet against the first top surface of the first girder. The first foot is welded to the deck sheet along a first length of the first cap channel. The second cap channel is coupled to a second top channel of the second girder, wherein the second cap channel comprises a second foot configured to press a second edge of the deck sheet against the second top surface of the second girder. The second foot is welded to the deck sheet along a second length of the second cap channel.
