摘要： PROBLEM TO BE SOLVED: To provide a vehicle jack device decreasing the ground bearing of a jack in place of a normal roller on weak ground or in a place where vehicle movement is not needed, and eliminating the fear of the vehicle running away. SOLUTION: This jack device has a jack base 20 mounted at the lower end of a roller type jack and having a grounding plate 22 that can be grounded in place of a roller 16. The jack base 20 is provided with an oscillating shaft 15 and a locking means such as a plunger pin 35, for oscillating the jack base 22 between a plate installing position where the grounding plate 22 covers the lower surface of the roller 16 and a receded position where the lower surface of the roller is exposed, and for locking the jack base 22 selectively in either position. During use of the grounding plate, the plunger pin 35 is controlled for unlocking and the jack base 20 is oscillated and engaged in a locking hole 33. After the grounding plate 22 is grounded by projecting the jack, the shaft 55 slides within an oblong hole portion 23a and the lower surface of the roller abuts against the grounding plate 22 whereby a vehicle body can be supported on the grounding plate 22.

摘要： PROBLEM TO BE SOLVED: To provide a supporting device for working vehicle of anchoring a jack promptly, and supporting a vehicle body stably and firmly with wheels dynamically lifted off positively. SOLUTION: A dynamic lift off inclination angle storing means stores dynamic lift off inclination angle θ1, or the inclination angle of a vehicle body in which a pair of front wheels F on the side where an extended jack 15 is mounted are dynamically lifted off when a pair of front jacks 15 are extended, according to the inclination angle of the vehicle 11. When an anchor detecting means detects that all of a plurality of jacks 15, 16 are anchored, a jack extension control means inclines the vehicle 11 to a dynamic lift off inclination angle θstored in the dynamic lift off inclination angle storing means by extending the front jacks 15, and extends the respective jacks 15, 16 based on the inclination angle of the vehicle 11 detected by the inclination angle detecting sensor 19.

摘要： PROBLEM TO BE SOLVED: To provide a support device of a working vehicle such that even if jacks are to be grounded by an automatic jack grounding device under conditions where jack bases are needed, as on soft ground, the jack bases can easily be displaced to proper positions between the jacks and the ground. SOLUTION: When each jack 15 or the like is extended by operating an automatic overhanging switch 17a and the grounding of each jack 15 or the like is detected by a grounding detecting sensor, then a jack contracting device stops the expansion of each jack 15 or the like and contracts each jack 15 or the like until the grounding of each jack 15 or the like is not detected. Thus when jack bases B, B... are laid below the jacks 15 or the like during grounding of the jacks 15 or the like, the jack base B can be displaced easily if shifted from its proper position.

摘要： PROBLEM TO BE SOLVED: To simplify a floor plate driving device in an outrigger for a work vehicle. SOLUTION: A pat base 4 connected to the lower end of a piston rod 1a of a jack cylinder 1 and a floor plate 5 overlapped on the lower side of the pat base 4 are connected to each other by a link pair 7 for moving the floor plate 5 while being deformed into the buckled state and the extended state, and an contact surface 18 is provided on the upper part of the track of the floor plate 5. When the floor plate 5 is raised and the top 7a of the link pair 7 is brought into contact with the contact part 18, the link pair 7 is deformed from the buckled state to the extended state, the floor plate 5 is inward moved to the housing position, while, when the floor plate 5 is lowered and the top 7a of the link pair 7 is separated from the contact surface 18, the link pair 7 is returned to the buckled state, and the floor plate 5 is outward moved to the advancing position.

摘要： PROBLEM TO BE SOLVED: To surely detect the working condition or the working position of a jack of the trunnion structure with simple constitution. SOLUTION: When a jack 10 is in the stored condition as indicated in (A), a jack cylinder 13 is in the contracted condition, and as a tube 13a is elevated, a link member 16 is oscillated in the upper-moving position and the jack cylinder 13 is moved in the storage position. On the other hand, when the jack 10 is in the contact condition with the ground, the jack cylinder 13 is in the expanded condition, and as the tube 13a is lowered, the link member 16 is oscillated at the lower-moving position, and the jack cylinder is moved to the service position and contact with the ground, a vehicle body is supported. The working condition or the working position of the jack 10 is detected by detecting the angle formed by the jack cylinder 13 and the link member 16 by an angle detecting device 20.

摘要： PROBLEM TO BE SOLVED: To safely perform setting up of a work vehicle in the sloped ground. SOLUTION: In this safety device, in a condition that a work vehicle tilted at a prescribed angle or more is detected by a tilt detector, in principle, even when a jack operating device 16 is operated, a jack 15 can not be actuated. However, a brake 5 in a cabin is stepped, in the case of inputting a brake detection signal of the brake, the jack operating device 16 is made effective, grounding operation of the jack 15 can be performed. Here, in the case of inputting the brake detection signal of the brake, by applying the brake to a front/rear wheel, whichever tire is first separated from the ground surface, a car body is prevented from slipping, jack operation can be safely performed.
