| 20110191003 | SKID STEER MACHINE WITH AUTOMATIC OPERATING RATIO CHANGE SYSTEM - A skid steer machine having separate left and right hydraulic propulsion units includes an operating ratio change system by which the ratio of the propulsion speed of at least one of the hydraulic propulsion units versus the hydraulic flow directed to the propulsion units can be changed from at least a first ratio to a second ratio and inversely. The operating ratio change system includes an operating ratio change ECU which controls an operating ratio change device to operate in at least a first ratio configuration or a second ratio configuration, and the operating ratio change system operates in an automatic operating mode where the operating ratio change ECU selects the operating ratio according to machine parameters received by the operating ratio change ECU. | 08-04-2011 |
| 20100000617 | CONSTRUCTION EQUIPMENT MACHINE WITH HYDRAULIC PRESSURE CONTROLLED SELECTING SYSTEM - A construction equipment machine has a lower frame and an upper frame rotatably connected, the machine having at least one hydraulic pilot circuit comprising a primary hydraulic pilot line running from the upper frame to the lower frame through a rotary joint for controlling the operation of at least one hydraulic device located on the lower frame, including: a pressure regulating system capable of setting in the pilot circuit a pilot pressure having a value; a hydraulic pressure controlled selecting system which is located on the lower frame and is fed by the primary hydraulic pilot line, at least two independent secondary pilot lines located downstream of the pressure controlled selecting system, and wherein said hydraulic pressure controlled selecting system is capable of selectively and independently supply or not supply pressurized fluid to the independent secondary pilot lines, responsive to the value of the pilot pressure. | 01-07-2010 |
