摘要： The invention relates to a method for, when necessary, automatically limiting a pressure in a hydraulic system (201) during operation. The mentioned system is arranged to deliver pressurized hydraulic fluid to at least one fluid actuated device (108, 109, 110) arranged to perform a work function, where the procedure comprises the following steps : to sense a pressure in at least one position of the system, to compare the detected pressure value, or an associated value, with a first predefined pressure limit, and to open a communication of fluid between the fluid actuated device (108, 109, 110) and a reservoir (243) through a first conduit (271, 275) if the sensed pressure value, or an associated value, exceeds the predefined limit.

摘要： A conveyor for a construction vehicle includes a frame removably connectable with the vehicle. The frame includes front and rear ends, first and second sides extending between the two ends, and upper and lower surfaces extending between the front and rear ends. An endless belt is disposed generally about the frame and at least one and preferably a pair of support members are connected with the frame. Each support member has a first, vertical portion connected with the frame first side and a second, horizontal portion extending generally beneath the frame lower surface and being disposeable upon a base surface. The two support members are configured to retain the entire frame and the belt spaced generally above the base surface so as to facilitate removal of the belt from the frame and alternatively facilitate installation of the belt upon the frame. Preferably, each support member includes an L-shaped bended bar.

摘要： A propulsion system is for a road milling machine with a rotatable cutter drum (3). The system includes four crawler assemblies (12) movably coupled with the mainframe so as to define front and rear, and left and right, pairs of crawler assemblies. Four steering actuators (14) are each coupled with a separate crawler assembly and each angularly displaces the crawler about a vertical axis (12a). A first pump (16A) is fluidly coupled with the left pair of crawlers and a second pump (16B) is fluidly coupled with the right pair of crawlers. A control (20) is configured to selectively operate the four actuators in a plurality of different steering modes, one steering mode being a circle steer mode, and to operate the two pumps such that one of the left and right pairs of crawlers are drivable by the first pump in one direction while the other pair of crawlers are drivable in an opposing direction.
