摘要： An apparatus for suppressing vibratory or quaky movements in travel of mobile type cranes, which facilitates the operation of re-starting the vehicle after temporarily stopping the engine, for example, at a gas station for fuel replenishment as well as operations for switching the mode of operation between vehicle travel and working modes. The apparatus includes for this purpose a memory means for storing at least information as to the mode of operation under engine working conditions before an engine cut-off, and a controller adapted to reproduce automatically the mode of operation before the engine cut-off, by setting a mode selector means in a reproducing position upon re-starting the engine based on the information stored in the memory means.

摘要： An apparatus for damping quaky movements of a mobile type crane includes the prohibition of the formation of a closed damping circuit through the opposing oil chambers of a boom uplifting cylinder in working mode or a crane operation in travel mode of the crane, enhancing safety in crane operation while ensuring effective quake damping action in vehicle travel. The apparatus includes a vehicle body supported on driven wheels; a boom pivotally supported on the vehicle body through a hydraulic cylinder for pivoting movements about a horizontal shaft; main hydraulic pumps connected through a transmission mechanism to an engine mounted on the vehicle body and switchable between on- and off-positions; a direction control valve for selectively supplying and draining the discharge oil pressures of the main pumps to and from a first load-holding main oil chamber and an opposing second oil chamber of the cylinder; a counter-balancing valve provided between the cylinder and directionh control valve; an accumulator provided between the cylinder and counter-balancing valve for suppressing quaky movements of the vehicle body; a mode selector means for switching the mode of operation between a vehicle travel mode forming a closed circuit through the first and second oil chambers and in communication with the accumulator, and a working mode cancelling the closed circuit and supplying and draining oil pressures separately to and from the first and second oil chambers; and a controller adapted to permit a switch to the travel mode position of the travel mode selector only when the main pumps are in an off state.

摘要： A throttle path for returning a part of pilot oil to a tank is formed by a tank path provided in a valve block of a control valve and a notch provided in a spool thereof. The above path is opened within a section from a vicinity of a stroke where a hydraulic actuator starts moving to right before a stroke end among a spool stroke of the control valve. An opening area of the above path is slowly reduced in accordance with an increase in the stroke at a final phase of the section.
