Bantam C-450 Concrete Finisher Overview

[MikePhua]

Machine Description
The Bantam C-450 is a specialized concrete finisher designed for large-scale paving projects such as bridge decks, flat slabs, tunnels, canals, and city streets. It is built with a pin-connected, all-welded steel main frame, offering robust durability and versatility for a range of construction environments.
Finishing Capabilities

• The C-450 features a 5-foot (1.52 m) long finishing cylinder that simultaneously compacts and finishes concrete in a single pass.
  
• A 6-foot (1.83 m) trailing screed with an innovative vibratory system provides a smooth final finish.
  
• The finisher frame width is adjustable in increments from 12 feet up to 72 feet, or with transition framework up to 104 feet for very wide paving.
  
• The machine includes a self-widening capability allowing operations on tapered decks and slabs.
  
• Equipped with a 360-degree turntable, the upper carriage allows maximum skewing of the undercarriage for perfect alignment with pavement edges.
  

Power and Controls

• Two engine options include air-cooled Honda gasoline engines or Yanmar diesel engines, both delivering approximately 19 hp.
  
• The hydraulic system offers a self-contained console with smoothly variable travel controls, positioned for operator safety and convenience, including touchscreen operation for high-production screeds.
  
• Power transition adjusters on the frame enable infinite, hydraulic adjustment of crown and grade for seamless paving results.
  

Undercarriage and Mobility

• The machine runs on hydraulically driven bogies with two drive and two idler wheels typically 3.25 inches wide, designed for stability and traction.
  
• Optional third wheel assist adds support on rails to reduce wheel load on overhang brackets.
  
• Tires for transport include 10 inch x 15 inch wheels with 12-ply tires and removable towing tongue for ease on job sites.
  

Additional Features and Options

• Auxiliary hydraulic circuits provide power for attachments such as vibrators and pan-type finishers.
  
• Adjustable auger assemblies handle large volumes of concrete, with vertical adjustment for mix consistency.
  
• Optional slope paver conversion kits allow finishing slopes up to 1:1 grade with minimal hand finishing.
  
• Features like hydraulic vibrator mounting and floating pans improve finishing quality on specialized concrete overlays.
  

Historical Context

• Bantam equipment has been known for reliable heavy construction machinery, including cranes and concrete finishing machines.
  
• The C-450 continues the legacy of delivering high productivity and accuracy essential for modern infrastructure projects.
