    • Low ground pressure tire chains for skid-steer loaders and other construction machinery. A track (12) for parallel drive wheeled vehicles (10) having spaced apart pairs of wheels (14,16) assembled with a plurality of base units (24) pivotally interconnected in series by opposing links (26), each base unit comprising a pair of opposing side supports (32) with a wedge portion (36) extending towards the opposing side support to wedgingly receive a portion of a tire in a gap between the opposing side support's. A pair of spaced-apart transverse cross members (34) extending between the side supports and define cavities (50) between a leading edge and the wedge portion for receiving fasteners to secure a bottom plate (52) to the base unit. The assembled track mounts around the tires of the loader to provide traction and floatation of the loader during operation in mud or sand.
    • 用于滑移装载机和其他工程机械的低地面轮胎链条。 一种用于平行驱动轮式车辆(10)的轨道(12),其具有间隔开的成对轮子(14,16),所述成对轮子与多个基座单元(24)组装,所述多个基座单元通过相对的连杆(26)串联枢转地互连,每个基座单元包括 一对相对的侧支撑件(32),其具有朝向相对的侧支撑件延伸的楔形部分(36),以在相对的侧支撑件之间的间隙中楔入地接收轮胎的一部分。 一对间隔开的横向横向构件(34)在侧支撑件之间延伸并且在前边缘和楔形部分之间限定空腔(50),用于接收紧固件以将底板(52)固定到基部单元。 组装好的履带安装在装载机的轮胎周围,以便在泥浆或沙运行期间提供装载机的牵引力和浮力。

    • PURPOSE: A track guarding apparatus for heavy construction equipment is provided to be replaced and maintained efficiently, protect lower rollers by reducing the entering of foreign materials from entering therein, and prevent separation of a track link. CONSTITUTION: A track guarding apparatus for heavy construction equipment comprises a swing motor(120), a sprocket(130), a track link(140), a plurality of lower rollers(150), and a track guard(160). The swing motor is installed in an undercarriage frame(110). The sprocket is installed in an undercarriage frame. The track link is installed on the circumference of the swing motor and the sprocket. The plurality of lower rollers is installed in the lower portion of an undercarriage frame. The track guard is installed in the front lower portion of the undercarriage frame of a track(100). The track guard comprises a plurality of lower roller shaft insertion grooves(161), an undercarriage frame fastening unit(162), an impurity discharge groove(163), and a track link separation preventing unit(164). The plurality of lower roller shaft insertion grooves is installed on the upper portion of the track guide. The undercarriage frame fastening unit is installed between a pair of lower roller shaft insertion grooves. The impurity discharge groove is installed in the lower portion of each undercarriage frame fastening unit. The track link separation preventing unit is installed in the both sides of the impurity discharge groove.
