    • An apparatus with a motor driven material removing tool for cutting, drilling, milling, sawing or grinding of concrete, stone or the like. The apparatus comprises three spaced apart operational groups, namely a working group, a vacuum source and control group, and a driving group. The groups are mobile and interconnectable and disconnectable by hoses and electrical cables. The working group comprises an interchangeable tool, such as a drill, drive motor means for driving and advancing the tool, and a tool holding device mounted on the outside of a rigid suction bell. The vacuum and control group includes vacuum producing means and electrical and fluid control units. The driving group has at least one hydraulic pressure pump with motor means for generating the hydraulic power for driving and advancing the tool.

    • An integrated hydrostatic transmission drive has a manifold attached to a pump drive that interconnects a pair of valves directly mounted on the manifold with the pump and a hydraulic actuator. One of the valves is operable between on-off positions and the second between two directional positions. The second valve is selectively solenoid operated between its positions but detent held in the selected position to act as a direction memory in the event of power cut-off and consequently continues drive of the actuator in the same direction when the power is reactivated. A filter may be provided in the manifold as well as relief valves.
    • 集成的静液传动驱动器具有连接到泵驱动器的歧管,其将直接安装在歧管上的一对阀与泵和液压致动器相互连接。 其中一个阀门可在开关位置和两个方向位置之间的第二个位置之间操作。 第二阀在其位置之间选择性地被电磁操作,但是止动件保持在所选择的位置以在断电的情况下用作方向存储器,并且因此在再次激活电力时继续驱动致动器在相同方向上。 可以在歧管中设置过滤器以及溢流阀。
