Epiroc has added the Intelligent Protection System to automate its heavy hydraulic breakers. The system’s AutoControl automatically adjusts piston length to the task. When the attachment breaks through material, the AutoStop function automatically shuts off the breaker to prevent blank firing. The system requires no operator intervention, the company says. It is available on Epiroc HB 2000, HB 2500, HB 3100, HB 3600, HB 4100 and HB 4700 breakers and will be added to the company’s other heavy hydraulic breakers this year.
Okada’s Rotating Pulverizer ORC Series can rotate 360 degrees to handle primary and secondary crushing operations. It features a double shell-shaped wedge for greater crushing ability, a speed valve for faster cycle times and 7.1-inch-long reversible cutter blades. The attachment is made of Hardox 400 steel. Its bracket is designed to protect components, such as the piston, rotate motor, speed valve and hydraulic hoses. Wear parts are protected by hardfacing. The series is compatible with excavators of 19 to 41 tons.
