TRAPPING SHOE LUBRICATION SYSTEM

A system for guiding movement of a chassis of a mining machine along a rack includes a shoe and a fluid line for receiving fluid from a fluid source. The shoe is configured to be coupled to the chassis and slidably engage the rack. The shoe is configured to extend at least partially around the rack. The shoe includes a first end, a second end, an inner surface, and an outer surface. At least a portion of the inner surface is configured to be positioned adjacent the rack. The fluid line includes an outlet positioned proximate the shoe for dispensing the fluid at an interface between the shoe and the rack. 种用于引导采矿机械的底盘沿齿条运动的系统，所述系统包括滑靴和用于从流体源接收流体的流体管线。所述滑靴被构造成耦接至所述底盘并可滑动地啮合齿条。滑靴被构造成至少部分地围绕齿条延伸。所述滑靴包括：第端、第二端、内表面和外表面。内表面的至少部分被构造成位于齿条附近。流体管线包括出口，所述出口位于滑靴附近，以便将流体分配至滑靴与齿条之间的交界面上。
