Abstract: During an operation, a control device (38) for performing output control of an engine (10) determines whether or not the engine (10) and/or an exhaust gas purifying device (18) has a malfunction. If it is determined that the engine (10) and/or the exhaust gas purifying device (18) has a malfunction, a highest rotational speed of the engine (10) is controlled to a second rotational speed (Nt) higher by a predetermined amount (?) than a first rotational speed (Ns) at which an engine maximum torque (Tm) before the malfunction can be outputted. In this case, a maximum fuel injection quantity of the engine (10) is limited so that a rated torque (Tr) before the malfunction can be outputted at the first rotational speed (Ns).

Abstract: A regeneration device that performs regeneration treatment of a particulate matter removing filter estimates a trapping amount of particulate matter trapped in the filter by two systems. Specifically, there are provided an estimating unit that estimates a first estimated trapping amount based upon a rotational speed of an engine and a fuel injection quantity and an estimating unit that estimates a second estimated trapping amount based upon a differential pressure across the particulate matter removing filter. The regeneration device determines whether or not the regeneration treatment is executed based upon whether or not at least one of the two estimated trapping amount is equal to or more than a preset trapping amount threshold value. Further, the regeneration device determines that there is a malfunction in the regeneration device in a case where the second estimated trapping amount is larger than the first estimated trapping amount.

Abstract: A regeneration apparatus for executing a regeneration process to an exhaust gas purifying apparatus and an engine control device that controls a rotational speed of an engine according to an instruction value by a rotational speed instruction apparatus are provided. When a directional control valve is in a neutral position, the engine control device controls the rotational speed of the engine to an automatic idle rotational speed (Nai) by an automatic idle selection unit regardless of the instruction value. However, when it is determined that the regeneration process of the exhaust gas purifying apparatus is executed in a state of controlling the rotational speed of the engine at the automatic idle rotational speed (Nai), the engine control device increases the rotational speed of the engine to a regeneration processing rotational speed (N1) higher than the automatic idle rotational speed (Nai).

Abstract: A control pressure switching valve is disposed between a displacement regulator and a pressure control valve. The control pressure switching valve is switched between a control position (j), in which a load sensing control pressure (PLS) is permitted to be outputted from the pressure control valve to the displacement regulator, and a control release position (k), in which the load sensing control pressure (PLS) to be outputted to the displacement regulator is reduced to a prescribed low pressure value. When the regeneration of a filter is determined to be necessary, the controller switches the control pressure switching valve to the control release position (k). When the load sensing control pressure (PLS) is reduced to the low pressure value with the control pressure switching valve switched to the control release position (k), the displacement regulator increases a delivery displacement of a hydraulic pump, thereby increasing rotational load of an engine.

Abstract: A regeneration device performs regeneration of a filter by burning particulate matter trapped by the filter of an exhaust gas purifying device. The regeneration device is configured to perform two types of processing, that is, automatic regeneration processing for automatically performing regeneration not on the basis of an operation by an operator and manual regeneration processing for performing regeneration by notifying an operator to manually perform the regeneration and by performing the regeneration on the basis of an operation by the operator. The automatic regeneration processing makes determination on whether or not to perform regeneration on the basis of an estimated trapping amount (H) estimated from an engine rotational speed (N) and a fuel injection quantity (F). The manual regeneration processing makes determination on whether or not to notify the operator on the basis of a differential pressure (?P) of the particulate matter removing filter.

Abstract: An engine (10) electronically controlled by a control device (33), a hydraulic motor (24) for traveling which is driven by a pressurized oil delivered from a hydraulic pump (13), and a traveling speed switching member (29) which switches a traveling speed by the hydraulic motor (24) at least in two stages of a low speed and a high speed. The control device (33) includes an output lowering determination unit for determining whether or not a fuel injection amount to be supplied to the engine (10) is limited and an engine output is in a lowered state and a low-speed control unit in which, when the engine (10) output is in a lowered state, a traveling speed is controlled to a low speed state kept lower than a high speed even if the traveling speed switching member (29) has been switched to the high speed side.

Abstract: An engine control system for a working machine measures the sulfur content of an exhaust gas since sulfur is detrimental to normal functioning of an exhaust gas aftertreatment device. Each time a key switch is turned ON to start an engine, the engine control system compares a remaining fuel amount memorized at the last stop of the engine and a remaining fuel amount detected at the current start of the engine. The engine control system performs a sulfur concentration measurement process only when the remaining fuel amount is increased. A target revolution speed Na appropriate for measuring the concentration of sulfur is set and when the temperature of the exhaust gas is within a predetermined temperature range and a target time has elapsed, the engine control system determines whether the sulfur concentration exceeds a threshold value. If the sulfur concentration exceeds the threshold value, an alarm display device is activated.

Abstract: A hydraulic drive system executing load sensing control is capable of efficiently combusting and removing filter deposits inside an exhaust gas purification device by pump output power increasing control when there is no actuator operation, eliminating interference between the actuator operation and the pump output power increasing control. A first solenoid selector valve selects between tank pressure and delivery pressure of a pilot pump. A second solenoid selector valve is arranged in a line leading the output pressure of a differential pressure reducing valve to an LS control valve for selecting between enabling and disabling of the load sensing control. When the exhaust gas purification device needs regeneration, a controller executes switching to make the first solenoid selector valve output the delivery pressure of the pilot pump as dummy load pressure and to make the second solenoid selector valve disable the load sensing control.

Abstract: When the actuator drive torque of a hydraulic pump is lower than a switching torque ?0, a controller closes a solenoid switching valve and makes a rotary electric machine function as a generator. With the increase in the actuator drive torque, the controller controls a pressure compensated flow control valve so that the flow rate of hydraulic fluid supplied from the hydraulic pump to a rotary hydraulic device decreases. When the actuator drive torque is higher than the switching torque, the controller opens the solenoid switching valve, makes the rotary electric machine function as an electric motor, and controls the pressure compensated flow control valve so that the hydraulic fluid discharged by the hydraulic pump is not supplied to the rotary hydraulic device. Consequently, shocks due to flow rate fluctuation are prevented when operational states of the rotary hydraulic device and the rotary electric machine are switched.

Abstract: A die cushion pad 13 is divided into four small pads 15 and a large pad 16. With this arrangement, a load applied to an action point of each of the small pads 15 can be equalized by the large pad 16, and an overturning moment arising between the action point and a reaction force point that equates the center of the small pad 15 can be canceled, thereby preventing flexure of the small pad 15. Accordingly, since flexure of the cushion pin and the like can be prevented, there is no risk that the cushion pin is frictioned against the penetrating hole of a bolster, and the lifting operation can be smoothly performed, whereby a higher-accuracy pressing forming operation can be realized.
