FB85 – FEEDER BREAKER (DEVELOPMENT CLASS)

Back to the list

OVERVIEW SPECIFICATIONS

Tailored for a perfect fit whatever your conditions. Feeder breakers allow haulage vehicles to quickly discharge their payloads. They break mined material down to beltable size and the ratio chains feed the broken material onto a conveyor belt, reducing the risk of conveyor belt jams and spillage. Cat® feeder breakers do the job with a large intake hopper capacity and high throughput rate. The high-speed/high-torque traction system has torque hubs instead of the hydraulic motors used on competitive models, delivering higher tram speeds for section moves and higher torque-to-ground for greater tractive effort. Features: • Up to 1 633 tonnes/hour (1,800 tons/hour) discharge rate • 27 200 kg (60,000 lb) pick force • 126 980 kg/strand (280,000 lb/strand) ultimate strength, engineering class, rollertype conveyor chain • 25 mm (1.0 in) AR 400 frame side steel 25 mm (1.0 in) plate fabricated hopper • Hydraulically-adjustable ground clearance • High tractive effort achieved with torque hub planetary crawler drive • 14 m/min (47 ft/min) tram speed
