About this document
Cat 330 Boom Hydraulic System Overview by hector is a document available to read on EtoBox.
The document describes the hydraulic system for raising a boom on an excavator. It has separate control valves for high speed and low speed boom raise operations. For high speed raise, pilot oil pressure opens both control valves to allow oil flow from both pumps to the boom cylinders. For low speed raise, only one control valve opens to provide oil flow from one pump. It also prioritizes oil flow to the boom circuit during combined boom raise and stick operations.
