Bridge Deck Finishing
GOMACO has the proven bridge deck finishers. All-welded steel construction provides the sturdiest, yet most lightweight finishers on the market.

Strictest Tolerances
GOMACO finishers assure you less than one-eighth inch (3 mm) tolerance in 12 feet (3.66 m) while finishing high-slump or low-slump concrete.

Crown Adjustment
GOMACO offers optional hydraulic power transition adjusters (PTAs) for on-the-go crown elevation changes made from the operator’s console. PTAs may be installed at pinconnected points.

Description

[column width=”1/1″ last=”true” title=”” title_type=”single” animation=”none” implicit=”true”]

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-450. It is easy to operate and saves time and labor costs on all of your concrete finishing projects.
