| PURPOSE:To enable vertical movement of a load-carrying platform in condition to maintain it in a horizontal state, by a method wherein a longitudinal guide part is formed on the working machine side and a catching part is formed at the forward end of a link. CONSTITUTION:With a swing arm 3 of a tractor 1 lifted and swung, the forward ends of right and left lower links 2 are swung in condition to point upward, and as a result, a load-carrying platform 10 is raised through a working machine mounting frame 9. In which case, the load-carrying platform 10 is raised vertically as it is guided through engagement of a guide roller, acting as a catching part 8, with top and lower holes serving as a longitudinal guide part 7. Thereafter, when the guide roller is brought into contact with under faces of the top and lower oblong holes and the swing arm 3 is further swung, the load-carrying platform 10 is tilted forward and is stopped. Reversely, when the swing arm 3 is swung downward, downward swing of the right and left lower links 2 and the guiding function of the guide roller and the top and the lower hole cause the load-carrying platform 10 to be lowered and brought to a stop. | ||||||

| PURPOSE:To improve the working efficiency by elevating straight a working machine mounting frame by the rocking action of a lifting arm while guiding it with an elevating guide frame. CONSTITUTION:An elevating guide frame 3 is connected to a tractor 1 by a connecting mechanism 2, and a working machine mounting frame 5 is connected to said frame 3 by an elevating mechanism 4 with free elevating motion. Moreover, a large diameter plate 8 and a small diameter plate 9 are fixed to a counterrotating shaft 7, a driving band 11 is led along the lifting arm 10 of the tractor 1 and the small diameter plate 9, and a driven band 12 is stretched around the large diameter plate 8 and the working machine mounting frame 5. And, by the rocking action of this lifting arm 10, a working machine 6 is elevated while it is expanded in the displacement thereof by the large diameter plate 8 and the small diameter plate 9. Hereby, the operation is extremely facilitated. | ||||||

| PURPOSE:To obtain an increased carrier lift and greater cargo loading capacity by using pulleys and a chain and by making the pulley at the tractor side attachable/detachable freely to a fitting metal. CONSTITUTION:An up-and-down rotatable rod 34 that fixes a pulley 31 is installed on a square sectioned bar 33 by means of an axle 36 and fixed to a fitting metal 32 by means of a pin 38. When the pin 38 is pulled off, the rotating rod 34 is disconnected from the pulley 31. While the pin 38 is inserted, a joint 51 is connected to a mast 16 in order to treble the carrier lift or connected to the chain 29 in order to double the carrier lift. With the pin 38 pulled off, the joint 51 is connected to the chain 29 and a pulley 23 is hoisted so that the carrier 55 can be lifted as much as the lift of the mast 16 and the carrier 55 can receive a great load. | ||||||

| PURPOSE:To change the inclination angle of a lift unit during cargo handling by constituting said lift unit so that the fitting position of an upper link can be freely changed on a mast frame. CONSTITUTION:Two lower links 5 forming a three-point link mechanism are supported on the lower end of a mast frame 25, but the fitting position of one upper link 9 is constituted so that it can be freely changed to a coupling section 33 or 34 at discretion. When the upper link 9 is supported on the coupling section 33, the mast frame 25, consequently a lift 37 is vertically moved up and down, but when supported on the coupling section 34, the lift 37 is moved up and down with a forward inclination, thereby the cargo can be prevented from collapsing during cargo handling on the ground 32 with retractions and protrusions. | ||||||

| PURPOSE:To facilitate the adjustment of the lift height by fitting a vertical mast to a three-point support unit of a tractor and fitting a lift elevated through a chain to the mast so that the coupling point of the chain with the tractor side can be freely adjusted up and down. CONSTITUTION:The front ends of two lower links 3 are pivoted to the rear of a tractor body 2 by means of a shaft 4, and the front ends of upper links 7 are pivoted to the upper fitting holes of fitting fixtures 6 above the link 3 so as to constitute a three-point support unit. The upper link 7 is constituted with forked section 10 and screw bars 8, 10' free of adjusting their lengths by rotation of a screw cylinder 9, and the centers of the left and right vertical masts 13, 13' are supported by the rear ends of the forked section 10, and the lower ends are supported by the rear ends of the lower links 3. A lift 30 free of elevating along the masts 13, 13' is provided, and one end of a chain 31 guided through a guide wheel 32 is coupled with the lift 30 and the other end is coupled with one of a plurality of holes 50 of a coupling section 49 with different heights. | ||||||
