The pilot valve unit is fixed, directly or indirectly, on the platform. The pilot valve unit can be mounted from below the platform, through the dedicated hole, and is fixed on the platform from above the platform. | 01-31-2013 |
| 037427000 | With significant bowl structure or manipulation | 3 |
| 20120055051 | TOOL CONTROL SYSTEM HAVING CONFIGURATION DETECTION - A tool control system for a scraper is disclosed. The tool control system may have a tool, a first tool actuator configured to move the tool, and a first sensor configured to detect a position parameter of at least one of the tool and the first tool actuator and to generate a corresponding first signal. The tool control system may also have a tool member operatively connected to the tool, a second tool actuator connectable to the tool member in a plurality of configurations to move the tool member, and a second sensor configured to detect a position parameter of at least one of the tool member and the second tool actuator and to generate a corresponding second signal. The tool control system may further have a controller configured to make a comparison of the first and second signals, and to determine a current connection configuration based on the comparison. | 03-08-2012 |
