摘要： [Object] To provide a construction machine that can prevent reduction in work efficiency even in work where a large reaction force is applied to a point of application.
[Solution] A hydraulic cylinder drives a working part. A hydraulic circuit supplies hydraulic oil to the hydraulic cylinder. A pressure sensor measures the pressure of the hydraulic oil supplied to the hydraulic cylinder. An input device is operated by an operator. A controller includes a thrust controller that controls the hydraulic cylinder based on the thrust of the hydraulic cylinder. The thrust controller calculates a required thrust value based on an operation amount of the input device, and obtains a thrust measurement of the thrust of the hydraulic cylinder based on the pressure measured by the pressure sensor. The thrust controller controls the hydraulic circuit such that a thrust difference between the required thrust value and the thrust measurement is minimized.摘要翻译： 本发明的目的在于提供一种即使在对作用点施加较大的反作用力的作业中也能够降低作业效率的建筑机械。 [解决方案]液压缸驱动工作部件。 液压回路向液压缸供应液压油。 压力传感器测量供应到液压缸的液压油的压力。 输入装置由操作员操作。 控制器包括推力控制器，其基于液压缸的推力来控制液压缸。 推力控制器基于输入装置的操作量来计算所需的推力值，并且基于由压力传感器测量的压力来获得液压缸的推力的推力测量。 推力控制器控制液压回路，使得所需推力值和推力测量值之间的推力差最小。

摘要： To enhance the quality of pavement of a curved road (RD) . An asphalt finisher (100, 100a, 100b, 100c, 100d, 100e) includes a tractor, a hopper that is provided on a front side of the tractor and that receives a paving material, a conveyor that feeds the paving material received by the hopper to a rear side of the tractor, a screw that spreads the paving material fed by the conveyor on the rear side of the tractor, a screed that levels the paving material spread by the screw on a rear side of the screw, and a controller. The controller is configured to drive the tractor such that a target trajectory (TPS, TPT) is generated based on a line which bisects an area of a road surface leveled by the screed right and left and a predetermined point (Q, P) of the asphalt finisher (100, 100a, 100b, 100c, 100d, 100e) follows the target trajectory (TPS, TPT) . The road surface includes a road surface of a curve portion (LC) of a road (RD) which is a construction target.

摘要： A shovel that can automatically perform the work of banking earth or the work of filling with earth is provided. The shovel 100 according to an embodiment of the present disclosure automatically performs at least one of the work of banking earth and the work of filling with earth. For example, the shovel 100 automatically performs the work of banking earth so that the ground in a predetermined area has a certain height. Furthermore, for example, the shovel 100 detects a depression in the ground based on information on the intended shape of the ground input by an operator's operation, obtained from the outside, or obtained in advance by the space recognition device 70 and information on the actual shape of the ground obtained by the space recognition device 70, and fills the depression with earth. In this case, the shovel 100 may detect an elevation of the ground and fill the depression with the earth of the elevation.
