SHOVEL SERIES, HYDRAULIC CIRCUIT OF SHOVEL, AND SHOVEL
PROBLEM TO BE SOLVED: To provide a shovel series, a hydraulic circuit of a shovel, and a shovel that satisfy different operational requirements for each shovel and enable components to be shared.SOLUTION: A shovel series includes a first shovel and a second shovel that share a first operation element and a first hydraulic actuator for driving the first operation element. The shovel series further includes: a first control valve shared by the first shovel and the second shovel for controlling a hydraulic oil flow for the first hydraulic actuator; and a second control valve controlling a hydraulic oil flow for a second hydraulic actuator that drives a second operation element different from the first operation element for the first shovel, and also controlling the hydraulic oil flow for the first hydraulic actuator for the second shovel.SELECTED DRAWING: Figure 6
【課題】異なる作用が要求されるショベル毎に、要求を満足させつつ、部品の共通化を図ることが可能なショベルのシリーズ、ショベルの油圧回路、及びショベルを提供すること。【解決手段】第１の動作要素と、前記第１の動作要素を駆動する第１油圧アクチュエータと、を共通で備える、第１のショベル及び第２のショベルを有するショベルのシリーズであって、前記第１のショベルと前記第２のショベルに共通して、前記第１油圧アクチュエータの作動油の流れを制御する第１制御弁と、前記第１のショベルでは、前記第１の動作要素と異なる第２の動作要素を駆動する第２油圧アクチュエータの作動油の流れを制御し、前記第２のショベルでは、前記第１油圧アクチュエータの作動油の流れを制御する第２制御弁と、を備える。【選択図】図６
