Abstract: An arrangement is provided in which the durability of an operation changing means is improved when this means is provided to the suspension mechanism in a suspension structure for a work vehicle. A maximum position (A1) and minimum position (A2) of the operation of the suspension mechanism are detected, and an intermediate position (B1) between the maximum and minimum positions (A1) and (A2) is detected. When the intermediate position (B1) departs from the target range (H1), the operation of the suspension mechanism is changed to the body raising side or body lowering side so that the intermediate position (B1) moves toward the target range (H1).

Abstract: The hydraulic suspension system comprises a suspension mechanism (100) for a traveling vehicle body, a suspension reference position variation mechanism (18) for varying a reference position of a suspension stroke of the suspension mechanism, and a stopped state detector (58) for detecting a state in which operation of the suspension mechanism (100) has stopped. The control management unit (60) controls the suspension reference position variation mechanism (18) so that when operation of the suspension mechanism (100) is detected by the stopped state detector (58) to be in a stopped state, the operation of the suspension mechanism (100) moves toward a target range, in preference to control based on a suspension stroke position obtained from a suspension stroke position sensor (37).

Abstract: A hydraulic suspension system includes a suspension base (16) supporting wheels, a hydraulic cylinder (19) for displaceably suspending the suspension base from a vehicle body, and an oil passage connected to the hydraulic cylinder. An accumulator (21, 23) is incorporated within the oil passage. A flow control valve (51) is incorporated at an oil passage portion between the hydraulic cylinder and said accumulator for controlling an amount of work oil flowing therebetween. A pressure sensor (56) is provided for detecting a cylinder oil passage pressure effective on the hydraulic cylinder. A control unit (57) is provided for controlling operation of the flow control valve, based upon a detection value from the pressure sensor.

Abstract: A vertical-type clothes press, in which clothes such as pants or the like held between a fixed board and a movable board can be pressed for smoothing or creasing, includes a mount base, a fixed board vertically mounted thereon and having a heater, a movable board having a hollow structure for hot-pressing clothes held between itself and the fixed board, a hinge mechanism which rotatably connects the lower ends of the fixed board and the movable board and mounts the movable board openably and closably on the fixed board opposite to each other, a lock mechanism for holding the movable board against the fixed board, a press sheet having one end attached to the connection between the fixed board and the movable board and rotatably provided between the movable board and the fixed board, reinforcements provided along the side end faces of the press sheet in a vertical direction, and a bias device provided on the opposite side of the hinge mechanism for pulling clothes or the like held between the fixed board and th

Abstract: An ironing apparatus which includes an ironing head, an ironing head rest including an electrical connection for supplying an electrical current to the ironing head placed on the ironing heat rest, a main tank for containing water and supplying the water to the ironing head, a water supply unit for supplying the water into the main tank, a controller for controlling the water supply unit and a load detector for detecting the placement of the ironing head on the ironing head rest, wherein the water supply unit is driven in response to an input from the load detector in response to the placement of the ironing head on the ironing head rest, thereby supplying water to the ironing head. When the ironing head is no longer in use, it retracts into the ironing head rest and is protected by a movable housing which is opened and closed by an electric drive.
