| PURPOSE:To support a carrying attachment approximately near the center of gravity thereof by a lift table, by supporting the lift table by a parallel link to permit it to rotate vertically forward pivotally. CONSTITUTION:Forward and rear parallel links 8a, 8b are pivotally mounted to a parallel link pivot 24, and the parallel links 8a, 8b pivotally support the lift table 21 on its upper end. The lift table 21 comprises body frame placing tables 21a, 21b at its forward and rear ends, so that when the body frame is placed, it can be fitted in place. When a hydraulic cylinder 33 is extended to rotate upward an arm 34 fixed integrally with the lift arm 9, the lift arm 9 and an engaging pin 35 rotate about a lift arm shaft 39 to pull backward a lift link 26. The forward end of the lift arm 26 is pivotally mounted together with the parallel link 8a to the lift table 21 to make the parallel links 8a, 8b stand upright. | ||||||

| PURPOSE: To reduce the capacity of a hydraulic pump by utilizing charged pressure of pressurized oil in a hydraulic stepless transmission as a partial load for driving an operator in such a vehicle as a tractor. CONSTITUTION: A stepless transmission 1 whose transmission case 7 is used for an oil tank is connected by a cooler 2 to a hydraulic pump 5. Said pump 5 is connected to an operation cylinder 3 by a pipe 11 and to the transmission 7 by a pipe 10. The amount of pressurized oil fed from the transmission 1 into the cooler 2 is compared with that of oil sent from the pump and if the former is larger than the latter, an extra oil is fed back into the transmission 7 through the pipe 10 and if smaller, an oil needed is absorbed from the transmission 7 through the pipe 10. The transmission 1 charges the pump 5 with oil pressure, which can reduce the capacity of the pump 5. COPYRIGHT: (C)1980,JPO&Japio | ||||||

| PURPOSE:To make it possible to facilitate the drive of a vehicle running on a road, by providing a means for locking wheels which are rear in the travel direction of a vehicle, in a impossible steering condition at a rectilinear travel position when front and rear working machines are both raised and the operator takes his seat. CONSTITUTION:When the operator sits on a seat 24, a seat detector 50 is turned on. Further, when front and rear working machines 27, 28 are both raised, an elevation detector 49 is turned on. With this arrangement, a signal from a steering instructing unit 42 is cut off by means of a gate circuit 51, and a rear wheel locking means 54 is energized. That is, a comparator 57 compares a signal from a turn angle detector 55, and a discriminator 58 judges the direction of return to energize one of solenoids 46, 48. With this arrangement, the rear wheels returns to the rectilinear position to lock a clocking cylinder 19. Accordingly, the front wheel 2 is alone steered during running on a road to facilitate the drive of the vehicle. | ||||||
