This C-450 is finishing one of the longest bridges being built in 2007 in the United States at 7000 feet (2133 m) long and 150 feet (45 m) wide. This C-450 features two power transition adjustors, double-drum finishing cylinders with mist bar, adjustable strike-off augers, and two float pans. The project is on the I-355 Toll Road in Chicago, Illinois.
Self-widening jacks are utilized on the finisher for automatic negotiation of the tapered deck. By adding the overhead truss, you have the advantage of taking the basic C-450 to greater widths, allowing the versatility to adapt to several projects. GOMACO engineers recommend the overhead truss system on the C-450 model at widths exceeding 76 ft. (23.16 m).
This C-450 finishes reinforced concrete flat slabs from 32 ft. (9.75 m) up to 102 ft. (31 m) wide on multi-story buildings as a base to support a suspended floor on this project in England. The hydraulic lift for the double-cylinder undercarriage enables it to be raised to clear blockouts in the floor. The independent mountings for vibrator and augers allow the operator to position these items to fit the mix design and finish required.
This C-450 is equipped with the rotary stinger vibrator for consolidation of the concrete, and also the twin adjustable auger. The rotary stinger vibrator automatically rotates 180 degrees at the end of each pass, and the auger is designed to be attached in any position for full strike-off control.
This contractor in Buffalo, New York, puts his C-450 finisher to work at night on this bridge deck project. The C-450 was set up to finish at a 38 degree skew. A 360 degree turntable on the upper carriage allows maximum skewing of the undercarriage to keep the finishing cylinder parallel to the center of the slab.
