    • An aggregate material spreader which is suitable for spreading aggregate material especially concrete on driveways, roadways and other paved surfaces. Work is performed by a roller-skid assembly adequate for rolling on forms and also skidding on the ground. It may have a built-in vibrating system and screed plates to grade material off at a desired level. Because of the skid embodiment it is designed to slip form. Finally a gliding float moves over the surface smoothing out all wrinkles.Also an alternate embodiment exists with a hopper built above the spreader with a sloping top attached on at the rear of said hopper at a lower position for concrete to discharge through for a finished product.
    • 一种适用于在车道,道路和其他铺设表面上铺展骨料特别是混凝土的骨料分散机。 工作是通过一个滚动滑道组件进行的,该组件足以在表格上滚动并且在地面上打滑。 它可以有一个内置的振动系统和熨平板,以将材料分级到所需的水平。 由于滑动的实施,它被设计成滑动的形式。 最后,一个滑翔的浮子在表面上移动,平滑所有的皱纹。 还有一个替代实施例,其具有在撒布机上方设置的料斗,其倾斜顶部附接在位于所述料斗的后部的下部位置,用于混凝土以排出成品。

    • A mobile cement laying machine for delivering concrete via tracks to areas which are difficult to access by truck. The mobile cement laying machine includes a carriage with a front end and a back end. A hopper is mounted to an upper side of the carriage toward the front end of the carriage. The hopper has an open top and a slot providing a lower opening into the hopper for dispensing cement from the hopper. A gate substantially closes the slot of the hopper. A pair of first rail wheels are coupled to the carriage towards the front end of the carriage. A pair of second rail wheels are coupled to the carriage towards the back end of the carriage.
    • 一种用于通过轨道将混凝土输送到难以通过卡车进入的区域的移动式水泥铺设机。 移动式水泥铺设机包括具有前端和后端的托架。 漏斗安装在托架的上侧,朝向托架的前端。 料斗具有开口顶部和狭槽,其向料斗中提供用于从料斗分配水泥的下部开口。 门基本上封闭料斗的槽。 一对第一轨道车轮朝向托架的前端联接到滑架。 一对第二轨道车轮朝向托架的后端联接到托架。
