New Case coupler and hammer for excavators

Case Construction Equipment recently added two new attachments – the Multi-Fit coupler and hydraulic hammer – for excavator operators interested in more speed and power on the job site.

Available on Case excavator models CX75 through CX470B, the Case-exclusive Multi-Fit coupler offers hydraulic quick-change operation from inside the cab. This cost-effective attachment saves time and money while increasing productivity. The coupler is especially useful for craning, utility and pipe-laying work, where buckets are changed frequently.

The patented mechanical blocking system on the coupler eliminates the need to manually insert a safety pin. A high-grade steel cast design produces a lighter, stronger and more durable attachment. The integrated lifting eye is part of the cast body, instead of being welded onto the coupler.

“This universal coupler works with a wide range of buckets and attachments from different manufacturers,” said Mitch Blake, Case marketing manager. “The coupler can grab and operate a bucket in both the excavator and ‘face’ positions. Hydraulic check valves keep the bucket secure.” 

Ideal for concrete work, roads and bridges and demolition projects, Case’s new hydraulic excavator hammer can be used with Case excavator models CX75 through CX290.

Complete with only two moving parts, the hammer requires no special tools for maintenance. A patented gas-assist operating cycle uses system hydraulics for 95 percent of the delivered energy. The shock absorption on Case excavator hammers creates a more comfortable operator environment too, due to the low recoil from the small amount of nitrogen charge used.

The new hammer will fit 7- to 29-metric ton excavators. “The impact of the hammer ranges from 825 to 4,500 feet per pound,” Blake said.

The hydraulic hammer comes with a lifetime limited warranty. “Seals are covered for two years and internal components are covered for three years,” Blake said. “The critical parts, however, are covered for a lifetime.”

Case offers nine standard excavator models. Case also produces four minimum swing excavator models, as well as a full line of compact excavators.
