Several parallel screw type augers are often used together. 3.8 Auger Drive: The Auger Drive is the final mecha
24、nism(s) employed to rotate the Auger(s). An Auger Drive can be hydrostatic, hydraulic or mechanical, or a combination of hydrostatic and mechanical. Mechanical Auger Drives must be protected by the inclusion of slip clutches or shear pins. Hydrostatic drives must be protected by the inclusion of pre
25、ssure protection devices.3.9 Cab: An enclosed area on a vehicle designed and intended to hold and carry an operator. 3.10 Capacity Rating: Also see Performance Rating.
