Four E Series Hammer models—H110Es, H115Es, H120Es, and H130Es—are now available for use on small and medium excavators and the Cat 450E backhoe loader. The hammers feature a symmetrical housing design that extends its life by allowing it to rotate 180 degrees. A curved front/back profile eliminates stress points and transfers forces to the hammer’s bottom. Automatic shutoff stops the hammer when it breaks through material. Caterpillar. 309-675-1000.
