C-750 & SL-750 Cylinder Finishers

GOMACO Corporation pioneered the development of the first cylinder finisher over 50 years ago. The late Harold W. Godberson, founder of GOMACO Corporation, developed and manufactured a bridge deck finisher to meet the growing needs for bridge markets. Considered to be a milestone, the cylinder finisher made GOMACO a recognized name in the construction industry.

Today, GOMACO cylinder finishers are designed for versatility with the C-750. It is easy to operate and saves time and labor costs on all of your concrete finishing projects.

Pin-connected sections provide fast setup time and the versatility to fit exact job requirements. The C-750 frame widths range from 16 feet (4.88 m) to 160 feet (48.77 m).

 

 


GOMACO C-750 Finisher Features Reliability, Serviceability, and Safety

Wider Width Finishing

• The C-750 provides high-production results with one-pass finishing for wider widths. Pin-connected sections provide fast setup time and the versatility to fit exact job requirements with frame widths ranging from 16 feet (4.88 m) to 160 feet (48.77 m).

• The C-750 features a 41 inch (1041 mm) wheelbase. The larger bogie drive motors are geared down to allow for continuous creeping advance.

• The console and operator’s platform are designed to be positioned anywhere within the 3.5 foot (1.07 m) deep framework sections, providing excellent operator visibility.

This GOMACO C-750 uses two, three-point finishing carriages for maximum efficiency to pave both sides of a bridge deck. The left carriage has the adjustable double augers and the right carriage has the standard augers, which operate ahead of the finishing cylinders.

 

 


´╗┐Versatile Frame and Finishing Width...

The C-750 cylinder finisher is designed for wider width finishing. The frame transition extensions in the center of the frame provide increased strength for widths over 120 feet (36.58 m) up to 160 feet (48.77 m).

 

 

 

 


SL-750 Slope & Canal Finisher

GOMACO’s SL-750 is a slipform cylinder slope and canal finisher. It is easy to operate and saves time and labor costs on all your concrete finishing projects. The SL-750 is designed for fast trimming and finishing, strict tolerances, with a minimum of handfinishing.

Hydraulic Oil: Console 15.3 gal. (57.9 L), Carriage 9 gal. (34 L).

 

CONSOLE
Self-Contained:
Hydraulic console with easy-to-operate controls, including variable travel. Can be positioned in other locations on the main frame for operator safety and convenience.
Carriage Drive: Designed for operator ease in controlling travel speed and direction of the carriage.

 

TRACTION SYSTEM
Traction Drive:
Two drive and two idler bogies standard. Drive bogies include two hydraulically driven flanged wheels, 3.25 in. (83 mm) wide for 2 in. (51 mm) square tubing or cupped wheels to run on 2 in. (51 mm) pipe. Optional urethane wheels or urethane wheels with removable flanges.
Traction Speed: Up to 31 fpm (9.4 mpm).
Automatic Advance on C-750: Electronically controlled at the end of the finishing pass. As machine advances, the undercarriage can change attack angle and concrete finishing resumes.

 

FRAME
Frame Construction:
All-welded steel, pin-connected, main frame, 16 ft. (4.88 m) to 120 ft. (36.58 m). Finishing width is normally 4 ft. (1.22 m) less than frame width indicated.

 

VARIABLE FINISHING WIDTHS
Extendible Frame for Finishing Widths:
4 ft. (1.22 m), 8 ft. (2.44 m), 12 ft. (3.66 m), or 16 ft. (4.88 m) increments. The C-750 assures a specified tolerance of one-eighth inch (3.2 mm) in 12 ft. (3.66 m). Includes a self-widening capability for use on tapered decks and slabs. Self-widens up to 12 ft. (3.66 m) as machine advances. A 360 degree turntable on the upper carriage allows maximum skewing of the undercarriage to keep the finishing cylinders parallel to the center of the slab.

 

POWER TRANSITION ADJUSTER (PTA) (optional)
Hydraulically operated for on-the-go crown elevation changes. Power transition adjusters can be installed at most pin-connected points.
