SHOVEL AND TURNING SPEED REDUCER
PROBLEM TO BE SOLVED: To provide a turning driving device capable of accurately performing oil inspection of lubricant right after operation completion of the turning driving device, and a turning speed reducer.SOLUTION: A shovel includes a turning motor and a turning speed reducer reducing rotation of the output shaft of the turning motor. The turning speed reducer includes: a first gear mechanism; a first gear case housing the first gear mechanism; a first oil detection pipe disposed in the first gear case; a first communication part communicating the inside of the first gear case with the first oil detection pipe; and a second communication part connecting the position of the first gear case higher than a position at which the first communication part is connected, with a high position of the first oil detection pipe.
【課題】旋回駆動装置の運転終了後、直ちに正確に潤滑油のオイル点検を行うことができる旋回駆動装置及び旋回減速機を提供すること。【解決手段】旋回モータと、該旋回モータの出力軸の回転を減速させる旋回減速機と、を備えるショベルであって、前記旋回減速機は、第１歯車機構と、前記第１歯車機構を収容する第１ギヤケースと、該第１ギヤケースに配設される第１検油管と、前記第１ギヤケースの内部と前記第１検油管を連通する第１連通部と、該第１連通部が接続されている位置より高い前記第１ギヤケースの位置と、前記第１検油管の高い位置を接続する第２連通部と、を備える。【選択図】図４
