Case Excavators — 2016 Spec Guide
Compact and Mid-Size Excavators Provide Application Flexibility
Case Construction Equipment’s Tier 4 Final compact excavators include three Case B Series models and two C Series mid-sized excavators. The three Case compact excavators have an independent, center-swing boom that allows operators to dig around and alongside obstacles. These units also have breakout forces ranging from 6,227 to 11,128 lbs and digging depths up to nearly 13 ft. These machines offer a true, zero-radius tail swing design that keeps the sides and back of the machine within the width of the tracks when rotating — even with the door open. Operators are able to dig and dump 180 degrees, right against obstacles, without a problem and with less risk of damaging the machine or worksite.
The three compact models (the CX31B, CX36B and CX55B) have a hydraulically-controlled backfill blade for stability and light dozing work. An integrated-flow pump system helps improve fuel efficiency and maximize strength by directing hydraulic power to where it’s needed. The CX31B and CX36B feature 23-hp engines with maximum digging depths of 9 ft, 3 in. and 10 ft, respectively. The 7,672-lb CX31B offers a bucket breakout force of 6,227 lbs, while the 8,554-lb CX36B also features a breakout force of 6,227 lbs. The CX55B provides a 37-hp engine and an operating weight of 11,312 lbs, which offers greater reach, 11,128 lbs of bucket digging force and a digging depth of 12 ft, 10 in.
The CX75C SR and CX80C mid-sized excavators are designed to bring the power and performance of a full-sized excavator into a smaller package for improved jobsite accessibility and convenience. Both machines offer a Tier 4 Final engine solution featuring a diesel oxidation catalyst (DOC)-only cooled exhaust gas recirculation (CEGR) system. Key advancements include a 5 percent improvement in fuel efficiency, a 7 percent faster cycle time, 20 percent larger fuel tank for extended runtimes and a 7 percent wider cab for increased productivity, says Case.
These models also offer 9 percent more hydraulic power than previous models for greater digging power and responsiveness.
The CX75C and CX80C weigh 16,200 lbs and 18,800 lbs, respectively. Both machines operate at 55.2 net hp, provide a digging force of 12,800 lbs and can reach a digging depth of 12 ft, 6 in. The CX75C is a minimum swing radius machine designed for work in more confined areas, such as along buildings and on roadsides.
Advice to Buyers
“When choosing a mini excavator there are multiple factors that a customer needs to take into account,” says Katie Pullen, brand marketing manager, Case Construction Equipment. “Are they working in confined spaces, how much dig depth do they need, what is their trailer rated for and how are they going to be using the machine? Knowing the answers to these questions will allow the customer to determine the appropriate size machine as well as the options. With conventional, short radius and zero tail models available, it can be confusing on which is best. The most important factor is for the job to get done safely with the right lifting capacities and proper amount of reach. This will help identify which model is right and optimize the overall return on their investment.”
