| 摘要： | Caterpillar has launched the new H190 S and H215 S performance series hammers, designed for use on large excavators. The two hammers are said to have efficient operating cycles, reducing wasted energy from internal heat and delivering more power to the tool. With piston and tool matched in diameter and mass, the hammers are said to offer high efficiency. Operators can switch modes from high frequency/low power to low frequency/high power, to suit the material being broken. Cat says that the units also provide operator comfort and machine protection as proprietary buffering material dampens vibration to the carrier. An automatic shut-off prevents blank firing and hammer damage. This can be turned off for horizontal and overhead operation in tunnelling applications. The hammers can be configured for joystick or pedal control to suit the operator preference when working in quarry, demolition and construction applications. Auto Stop prevents hammering when the tool breaks through material, avoiding damage. |
