To provide a braking device of a track traveling type machine capable of simplifying and miniaturizing a structure by reducing the number of component parts and of reducing cost.SOLUTION: A braking device 40 of a track traveling type machine (a container crane 10) includes an equalizer beam 32 on which traveling wheels 31 freely rolling along a traveling rail Rx are provided, and presses a brake pad 41, which is mounted on a lower surface of a pressing frame 43, against the traveling rail Rx to perform braking by telescopic operation of a fluid pressure cylinder 42 provided on the equalizer beam 32. The braking device includes: a support bracket 32b projected from a side surface of the equalizer beam 32 and mounted with the fluid pressure cylinder 42; and a cutout part 33 formed on a lower part of the equalizer beam 32 to be engaged with the pressing frame 43 and receiving horizontal force in the longitudinal direction of the traveling rail Rx acting on the pressing frame 43 in performing braking.SELECTED DRAWING: Figure 1

    【課題】部品点数を削減して構造の単純化並びにコンパクト化を図ることができ且つコストダウンを図り得る軌道走行式機械の制動装置を提供する。【解決手段】走行レールRxに沿って転動自在な走行車輪31が配設されたイコライザビーム32を備え、イコライザビーム32に配設される流体圧シリンダ42の伸長作動により、押圧フレーム43の下面に取り付けられたブレーキパッド41を走行レールRxに押し付けて制動を行う軌道走行式機械(コンテナクレーン10)の制動装置40において、イコライザビーム32側面から突設され且つ流体圧シリンダ42が取り付けられる支持ブラケット32bと、イコライザビーム32の下部に押圧フレーム43と係合するよう形成され且つ制動時に押圧フレーム43に作用する走行レールRx長手方向の水平力を受ける切欠部33とを備える。【選択図】図1
