CF-790 canal finisher

CF-790 Canal Finishers


GOMACO’s CF-790 canal finisher is specifically designed for finishing wider width canals and is easy to operate and saves time and labor costs on all your canal finishing projects. Because no two canals are alike, the CF-790 can be custom ordered to fit your exact specifications.

The CF-790 canal finisher has welded steel tubular lattice-type upper structure with end-car mounted crawler tracks. The finisher sub-frame is made up of welded high strength steel lattice panels, with pin-connected sections providing fast setup time and the versatility to fit exact job requirements for frame widths up to 72 ft. (21.95 m). Bottom wedge assemblies allow the CF-790 to accommodate slopes from 4:1 to 1:1. The finisher bottom frame can be partially disassembled, and the remaining slope frames along with the finishing carriages can be winched up under the upper structure for moving in and out of canals.

The CF-790 has two single cylinder finishing carriages equipped with mounted or independent augers. Optional externally vibrated undercarriages or trimming undercarriages are available as needed. The CF-790 can be equipped with frame-mounted slipforms with adjustable framework across the rear of the slipforms for controlling the finished slab width and providing data to hand finish the top cap.









Unique Design for Ease in Project Mobility and Transportability

The finisher bottom frame can be partially disassembled and the remaining slope frames along with the finishing carriages can be winched up under the upper structure for ease in moving in and out of canals and for transporting from one project to another. This unique design provides a tremendous savings in time and labor costs.
