摘要： PURPOSE: To accurately update azimuth data by a method wherein the deviation of azimuth of a gyro is obtained based on time series data of difference between an azimuth of a vehicle measured by the gyro and an azimuth of the vehicle measured by a global positioning system(GPS). CONSTITUTION: A signal processing device 13 of a key station 1 calculates difference between measured position data inputted from a GPS satellite 3 via a GPS receiver 12 and position data of a predetermined base station and transmits the correction data to a child station 2. The child station 3 receives measured position data from the satellite 3 via a GPS receiver 22 and correction data from the key station 1 via a radio modem 24, respectively. A signal processing device 25 calculates renewed position data of the child station 2 to store it and detects an azimuth based on the GPS in accordance with deviation between present position data and position data in one scanning before. The azimuth is stored in a memory 27 together with an azimuth obtained by a gyro 26 and an azimuth correction device 28 corrects the azimuth obtained by the gyro in accordance with the time-series stored data.

摘要： PURPOSE: To easily operate the loading device with a reduced number of operation levers by providing an operation lever for switching a control valve in a main valve and an operation switch for switching remaining control valves through a solenoid valve, and providing the operation lever with the operation switch. CONSTITUTION: With operation switches 24 and 25 ON, electricity is fed to the solenoids of solenoid valves 22 and 23, which are switched through electromagnetic operation to move the spools of control valves 2a and 2d with hydraulic pressure applied from an assist pump 17, thereby switching the control valves 2a and 2b. Thus, the positions of the control valves 2a and 2d are switched and then the hydraulic pressure from a main pump 9 is applied to an actuator 1 to place the loading device according to the hydraulic pressure. When the operation switches 24 and 25 are OFF, the solenoid valves 22 and 23 are not switched and the control valves 2a and 2d are not switched, so that the control valves 2a and 2d disconnect the main pump 9 and an actuator part 1 from each other.

摘要： PURPOSE: To provide a safety device for an industrial vehicle, for preventing traveling of a vehicle in the malfunction of a forward and backward lever, and for securing safety. CONSTITUTION: A safety device is provided with a speed sensor 31 for detecting the traveling speed of a vehicle, a limit switch 32 for detecting depressing of an accelerator pedal 9, and a controller 33 for forcibly making a spool of a switching valve 2 in the neutral position when the fact that this limit switch 32 is off, and the vehicle is stopped is judged from a speed detecting signal of the speed sensor 31. Since the spool of the switching valve 2 is made in the neutral position when the accelerator pedal 9 is not depressed, and when the vehicle is stopped, the danger that the vehicle travels can be avoided even if a forward and backward lever 1 is mistakenly operated by contact. The engine brake can be made to act by remaining clutches 3, 4 put in connection during traveling of the vehicle, and the danger that the speed of the vehicle is rapidly increased can be avoided, and safety can be secured.

摘要： PURPOSE: To change the direction of a wheel by normal human force, even if a hydraulic pump is stopped, by providing a second gear having the number of tooth more than that of a first gear and engaging with the first gear. CONSTITUTION: During a hydraulic pump is driven, when a steering shaft 31 is rotated by a handle 20, this rotation force is transmitted to the spool 23 of a switching valve via a first gear 1, a first clutch 3, and third and fourth gears 4 and 6 to open the switching valve of an orbit roll 21 to switch a wheel in a right and left direction. When the hydraulic pump is stopped, the rotation force of the steering shaft 31 is transmitted to the spool 23 of the switching valve via the first gear 1, a second gear 2, a second clutch 5, and the fourth gear 6 to switch the wheel in a right and left direction with the orbit roll 21 acted as a hand pump. At that time, since the number of the teeth of the second gear 2 is more than that of the first gear 1, thereby rotating the spool 23 by small force.

摘要： PURPOSE: To remove soil and sand, etc., fixed onto a road surface surely by a method wherein a boom is mounted on a car body, a bucket is installed at the free end of the boom through a wheel and a scraping bar and an energizing section conducting revolution are set up to the front section of the bucket while fitting a brush for cleaning to the rear of the bucket. CONSTITUTION: A boom 2 is lowered while a bucket 4 is brought to a horizontal state by a ring device 11. The bucket 4 is borne on a road surface 6 through wheels 5. The upper section of a scraping bar 20 is formed as a coil section 20a wound on a support shaft 18. The lower end of the scraping bar 20 is tilted towards a rear section from an upper section and grounded at that time. When a car 1 is moved forward, the lower ends of each scraping bar 20 are grounded on the road surface 6 and advanced. The lower ends of the scraping bars are abutted against fixed soil and sand 37, and soil and sand are scraped off. Thereafter, soil and sand are collected into a storage chamber with other dust by a brush 8. When the scraping bars 20 collide with projections, they are turned upwards centering around an upper section against the energizing force of the coil sections 20a. Accordingly, a car for cleaning the road surface can have extremely excellent capacity as a dustcart.
