PROBLEM TO BE SOLVED: To provide a grease supply system for a swing device capable of sufficiently supplying lubricant agent at the time of operation and capable of restricting wear at rolling surfaces of rollers at an inner ring and an outer ring and to provide a construction machine.SOLUTION: There is provided a swing detector 100 for detecting whether or not a swing device 7 is being operated, i.e. an inner ring 20 and an outer ring 40 are relatively moved. The swing detector 100 is operated to detect it on the basis of an operation signal 102 of a swing motion operating lever 101 arranged at a driver's room 14 that the inner ring 20 and the outer ring 40 are moved to each other and when it is detected by the swing detector 100 that the inner ring 20 and the outer ring 40 are moved to each other, it is constituted that a controller unit 200 outputs a grease supplying instruction 201 to a grease supply device 90.SELECTED DRAWING: Figure 1

    【課題】運転時に効率良く潤滑剤の供給を行うことができ、内輪や外輪における転動体の転動面の摩耗を抑制し得る旋回装置の給脂システム及び建設機械を提供する。【解決手段】旋回装置7が運転中であるか否か、即ち内輪20と外輪40とが相対運動しているか否かを検出する旋回検出器100を設け、旋回検出器100は、運転室14に設けられた旋回運転操作レバー101の動作信号102に基づき内輪20と外輪40とが相対運動していることを検出するようにし、旋回検出器100によって内輪20と外輪40とが相対運動していることが検出された際には、制御器200から給脂装置90に対して給脂実行指令201を出力するよう構成する。【選択図】図1
