Grade and slope lockout for extender movement of construction machine
Systems and methods for implementing a machine control system in a construction machine having an implement with an extender. The machine control system may include an acceleration sensor mounted to the implement and a processor configured to perform various operations. The operations may include determining that the extender is not moving and in response operating under a first control scheme. Operating under the first control scheme may include receiving acceleration data from the acceleration sensor, generating an estimated slope of the implement based on the acceleration data, and modifying a slope of the implement based on the first estimated slope by causing movement of at least one tow arm. The operations may also include determining that the extender is moving and in response operating under a second control scheme. Operating under the second control scheme may include maintaining the slope of the implement substantially constant.
Rolling device, in particular for placing bulk materials on the ground
A rolling device includes a chassis equipped with a reservoir for holding bulk materials and a smoothing table, the smoothing table having a leading edge arranged transversely to the direction of movement of the device, and the bottom of the reservoir being provided with a discharge opening arranged between the leading edge of the smoothing table and the wheels of the rolling chassis of the device, the wheels of the rolling chassis being driven and the rolling chassis being mounted so as to be able to tip about the axis of rotation of the wheels, the reservoir and the smoothing table forming a movable assembly, and the position of the movable assembly can be adjusted by an adjustment unit so as to be able to adjust the height of the smoothing table and the discharge opening, and the inclination of the smoothing table.
Road paver with quick coupling apparatus for the transverse distribution device, and method
A road paver includes a height adjustable auger assembly. A support housing of the auger assembly is attached to the road paver via a quick coupling apparatus that facilitates height adjustment of the auger assembly. A plurality of sliding devices are inserted into a respective oblong hole, each oblong hole includes an expanded insertion portion and a vertically extending portion. Wherein the vertically extending portion facilitates height adjustment of the auger assembly. A method of coupling the auger assembly includes inserting the sliding devices into respective oblong holes and adjusting the height of the auger assembly by moving the sliding devices between the expanded insertion portion and the vertically extending portion of the oblong holes.
SYSTEM AND METHOD FOR OPERATING A PAVING MACHINE
A method for operating a paving machine is provided. The paving machine includes a screed assembly, a washdown system for washing the paving machine and the screed assembly and a ventilation system. The method includes receiving, by a controller, an operational data associated with the paving machine, and determining an operational state associated with the washdown system. The method further includes controlling, by the controller, an operation of the ventilation system based on the operational data associated with the paving machine and the operational state associated with the washdown system.
Ventilation system and method for cold planer machine
A ventilation system and method for a cold planer are provided. The ventilation system includes a settling box inside a water tank. The settling box includes a body. The body includes at least one sidewall defining an air inlet having a first cross-section to accept dust and fumes generated by a milling drum operation of the cold planer but to reject particles from the milling drum operation at or above a predetermined size. The settling box further includes an air outlet having a second cross-section less than the first cross-section of the air inlet. The ventilation system further includes an outlet pipe connected to the air outlet, a fan and a cleaning system. The fan is configured to pull air from below the air inlet into the settling box, through the air outlet and to the outlet pipe.
ROADBUILDING MACHINE AND METHOD FOR OPERATING A ROADBUILDING MACHINE
A method for operating a roadbuilding machine and a roadbuilding machine, in which the health risks to the operator during operation are reduced without the paving quality of the roadbuilding material being reduced in the process. This is achieved by way of an undercarriage and/or at least one further component or, respectively, working component of the roadbuilding machine being remotely controlled by an operator, who is located outside the roadbuilding machine, via a transmitting module. In order to operate a roadbuilding machine, an operator is tied to the roadbuilding machine and therefore exposed to harmful fumes. In addition, the flexibility of the operator is reduced as a result.
Truck position control system for milling operations
A control system (40) is disclosed for a mobile machine (10) configured to transfer material into a receptacle (18). The control system may include a first sensor (44) configured to generate a first signal indicative of one of a speed of the mobile machine and a distance between the mobile machine and the receptacle, a display system (56) having at least one display device (58) configured to show information relating to one or more of the mobile machine and the receptacle to an operator of the receptacle, and a controller electronically connected to the first sensor and the display system. The controller may be configured to determine a relative speed of the receptacle with respect to the mobile machine based at least in part on the first signal and generate on the at least one display device a first visual indicator (68) indicative of the relative speed of the receptacle with respect to the mobile machine.
Material tracking for milling machines
A milling machine includes a cutting rotor, a foldable conveyor, a sensor, and a controller. The cutting rotor is configured to mill material beneath the milling machine. The foldable conveyor is configured to receive and dispose the milled material and includes a first section and a second section foldable with respect to the first section at a fold structure. The sensor is positioned on the milling machine and configured to sense a value indicative of a force acting on the second section. The controller is configured to determine an amount of the milled material within the second section of the foldable conveyor using the value indicative of the force.
Milling machine with hydraulically actuated rotor drive transmission
A milling machine includes a rotor drive transmission having a plurality of gears disposed between a prime mover and a cutting rotor. The rotor drive transmission is associated with a rotor transmission hydraulic circuit including a hydraulic gearshift actuator to engage the plurality of gears in one or more gear ratios and a gearshift directional control valve to direct hydraulic fluid to and from the hydraulic gearshift actuator. In occurrence of a fault condition, the rotor transmission hydraulic circuit includes a gearshift trapping valve to maintain hydraulic pressure in the hydraulic gear actuator and the engaged gear ratio of the rotor drive transmission.
Depth guide for paving machine
A depth guide to be used with a road paving machine having a movable screed, said depth guide allowing the operator of the road paving machine a simple means for visually assessing whether the pavement layer being deposited by the road paving machine and formed by the screed is of the proper thickness.
