The system for controlling an automatic leveling for heavy equipment, in which a lower frame having a traveling means and an upper frame are combined together by a tilting means, includes a sensor unit, provided in the equipment, for sensing twist angles of the lower frame and the upper frame against a reference horizontal surface and a traveling speed of the equipment; a control unit for receiving the twist angles and the traveling speed, setting a limit of an operation time for the automatic leveling in a standstill state of the equipment while calculating a corrected angle to which a twist angle of the upper frame is to be corrected, without setting the limit of the operation time for the automatic leveling, in a traveling state of the equipment, and generating a control signal for instructing an operation of a tilting means in accordance with the corrected angle; and a driving unit for performing a tilting control through the tilting means in accordance with the received control signal. | 04-02-2009 |
| 20090115148 | LEVELING APPARATUS FOR EXCAVATOR AND FORESTRY MACHINE EQUIPMENT - A leveling apparatus for excavator and forestry machine equipment is provided. The leveling apparatus is mounted between an upper swing structure and a lower frame formed on a lower driving structure including a swing bearing, left and right track chassis, and a front arm and a rear arm connected to upper parts of the track chassis, to keep a horizontal level of the upper swing structure against an inclined ground. The leveling apparatus includes a swing bearing mounting plate mounted on a lower part of the swing bearing and including a pair of pivot support parts and a pair of second piston holders; a support plate fixedly installed on an upper part of the lower frame and having a pair of pivot support parts; a tilt plate mounted between the swing bearing mounting plate and the support plate to be tilted, and including a pair of first pivot holders, a pair of second pivot holders, a first shaft; and a second shaft; and a pair of first actuators and a pair of second actuators; wherein the tilt plate includes a vertical center line crossing a center line in a length direction of the lower frame, and the respective actuators are installed to be radially apart from the vertical center line. | 05-07-2009 |
| 20090212511 | SKATE WITH ANTI-TIPPING BRACKET FOR USE WITH FLOOR TRACK STORAGE SYSTEM - A skate for a storage device for use with a floor track system comprises an elongate inverted U-shaped channel member having front and rear end portions. Front and rear wheels within the channel member are journaled thereto for rotation along the rails of the floor track system. A storage device is mounted on a pair of parallel skates for movement along the rails. An anti-tipping bracket is secured to the channel member, and the anti-tipping bracket includes a framework outwardly extending from the front end portion of the channel member to prevent forward tipping of the storage device by engaging forward support structure. | 08-27-2009 |

| 20080203684 | Road-Building Machine - The invention relates to a road-building machine whose left front wheel ( | 08-28-2008 |
| 20110079968 | Turf groomer - A turf groomer for grooming and maintaining synthetic turf including a base structure, and at least one brush arm, at least one rotating member, and a plurality of rake tines connected to the base structure. The at least one brush arm has a plurality of arm segments and is positioned at a front region of the base structure. The at least one rotating member has one or more prongs extending radially from its center, is positioned along an axis of rotation, and is distally spaced from the at least one brush arm. The plurality of rake tines is distally spaced from the at least one rotating member. The turf groomer may include a second brush arm positioned at a rear region of the base structure, and a static reducing device to inhibit the buildup of static electricity as the turf groomer passes over the turf, and/or an extension brush arm. | 04-07-2011 |
| 20110298188 | Construction Machine And A Method For Controlling And/Or Monitoring The Milling Depth Of A Construction Machine - The invention relates to a construction machine, especially a road construction machine, comprising a machine frame and a chassis carrying the machine frame with several wheels, with at least one of the wheels being connected with the machine frame via a height-adjustable lifting column and the lifting column comprises a distance measuring device for measuring the adjustment of the lifting columns with a sensor. The invention further relates to a method for controlling and/or monitoring the working depth of a working device for processing the ground arranged on a height-adjustable construction machine, especially a road construction machine. | 12-08-2011 |
| 20150021866 | 4-Way Leveling - Representative implementations of devices and techniques provide leveling for a vehicle, such as an overland vehicle. A leveling signal is received by a leveling arrangement coupled to the vehicle at a wheel position. The leveling arrangement rotates a rocker plate with respect to the body of the vehicle, changing a location of a wheel coupled to the rocker plate with respect to the body of the vehicle. In an aspect, the leveling signal is based on a first vehicle sensor signal representing a lateral tilt of the vehicle and/or a second vehicle sensor signal representing a pitch angle of the vehicle. | 01-22-2015 |
| 280600156 | Longitudinally extending support arm | 2 |
| 20100044980 | CHASSIS ADJUSTMENT SYSTEM - A machine, such as a mobile asset, vehicle, or agricultural vehicle, includes a chassis, an adjustment system, and a wheel. The adjustment system replaces a conventional non-extendable leg connected between the chassis and the wheel of the machine. The adjustment system can extend and withdraw in length, such that the height of the machine can vary as needed. | 02-25-2010 |
| 20110084457 | MODULAR ROUGH TERRAIN VEHICLE - A rough terrain vehicle including an elongated main frame for supporting a self-contained v-haul body; first and second forwardly-extending frame arms located on opposite sides of the main frame; third and fourth rearwardly-extending frame arms located on opposite sides of the main frame, each arm having a wheel mounted thereon. Also included are first and second cross members pivotably connected to the arms configured to enable the main frame and the frame arms to pivot about a lengthwise axis of the main frame. First and second length-adjustable member operatively connected to the first frame arm and the third frame arm and the second frame arm and the fourth frame arm, respectively; selective movement of each length-adjustable member causing the associated arm to move up or down; and a level detector for producing and applying leveling signals to each of the length-adjustable members to maintain the elongated main frame in a relatively level orientation when the vehicle encounters uneven terrain. | 04-14-2011 |
