    • A liner (42) for a machine body (12) includes a first layer (44) including a first polyurethane having first material characteristics, and a second layer (46) coupled to the first layer. The second layer includes a second polyurethane having second material characteristics different than the first material characteristics, and the first layer and the second layer are chemically bonded to one another. A liner system (70) includes a liner and a liner retention system (72) configured to couple the liner to the machine body. The liner retention system includes at least one retention strip (76) configured to be coupled to the machine body. The retention strip has a cross-section forming a lateral profile (84). At least one edge (86) of the liner has a shape configured to substantially correspond to the lateral profile of the retention strip.
    • 用于机体(12)的衬套(42)包括第一层(44),其包括具有第一材料特性的第一聚氨酯和耦合到第一层的第二层(46)。 第二层包括具有与第一材料特性不同的第二材料特性的第二聚氨酯,并且第一层和第二层彼此化学键合。 衬垫系统(70)包括衬套和衬套保持系统(72),衬套保持系统构造成将衬套耦合到机器本体。 衬垫保持系统包括构造成联接到机器主体的至少一个保持条(76)。 保持条具有形成横向轮廓(84)的横截面。 衬套的至少一个边缘(86)具有被配置为基本对应于保持条的侧向轮廓的形状。
