摘要： PURPOSE: To eliminate irregular sludge discharge works or loss of molten metal changed into products by a method wherein a working vehicle is advanced to a specified position in front of a furnace, a sludge removing arm is aligned with a height of furnace port, thereafter the arm is repeated in its predetermined operation pattern in accordance with a predetermined program. CONSTITUTION: In order that a sludge discharge operation is carried out by a working vehicle, pushing-out arms 12, 13 are set to be the shortest state, a slant cylinder 10 is operated to have a horizontal state, the vehicle is stopped at a predetermined position in front of a furnace under a state in which the arms are placed at the lowest position by a lift cylinder 9. The arms are fixed and stabilized with a jack cylinder 4. Arms are lifted up and retracted manually and their position set is completed in compliance with the height of the furnace port. The arms are once retracted to their shortest lengths and a push button of 'AUTO MATIC START' is depressed, resulting in that the arm 13 may repeat motion patterns of moving forward→descending → retracting → slant ascending → retracting → discharging →advancing by a desired number of times with a scraper 14 being fixed at the extremity end of the arm and then its operation is completed. Speeds in ascending and retracting operations of the scraper 14 are adjusted in response to a slant angle of a furnace wall at the furnace port and then sludge of dross can be removed in compliance with a slant angle at the furnace port.

摘要： PROBLEM TO BE SOLVED: To obtain a self-propelled carriage which can correct the slippage between a regular running route and an actual running route accurately without being disturbed by the skillness of a driver. SOLUTION: Plural driving wheels are provided, and a vehicle operated obliquely or operated laterally along the running lines applied on the running road surface; a disk form of right side base board 11R; a cylindrical form of member 13R provided vertically at the center of the right side base board 11R; and a slit light generator 14R which is of a cylindrical form, installed and fixed to the tip of the cylindrical member 13R, and irradiates a slit light Os of a guide angle θg same as the preset steering angle of the plural driving wheels to a deck 5a; are provided. The driver carries out the handle operation to make an optical line Ok and a running line L obtained on the deck 5a parallel or coincident each other.

摘要： PROBLEM TO BE SOLVED: To set up the direction of a tire automatically in the longitudinal direction of a car body and prevent a collision or the like without resting on the eyeing and intuition of a driver by installing a tire direction control means which sets up the tire direction of a conveying truck in the longitudinal direction of the car body at a time when a loading space goes down in a state of being set to a rectilinear travel mode. SOLUTION: In order to retract from a portal pallet, a descent of height of a loading space is started by traveling of a rectilinear travel mode. A truck controller 12 makes a hydraulic cylinder operate, thereby adjusting an extent of car height. When this loading space goes down up to the limit position, a check of the travel mode is carried out by the truck controller 12. Subsequently, the rectilinear travel mode is checked, then a tire angel is judged on the basis of the output of a tire angel detector 14, commanding the tire angle to a tire turning actuator 15. Accrodingly, the tire direction is properly set up in the longitudinal direction of the car body. In succession, the tire angle is reconfirmed. With this constitution, a conveying truck is able to avid colliding with the portal pallet.

摘要： PROBLEM TO BE SOLVED: To avoid collision between a carrier and a portal pallet, and which is conventionally so avoided that a driver gets out from the carrier and confirms the positional relation between the carrier and the portal pallet, when the rectangular carrier in its plan view is passed through under the portal pallet formed by having a rectangular load carrier in its plan view and a leg part for supporting the mount. SOLUTION: A light source 10 emitting a visible radiation spreading planarly on the vertical face toward the axial center of a carrier 0 is provided on the carrier 0 side, an indicator 11 formed in a prescribed direction in relation to the axis of a portal pallet 1 is provided in the portal pallet 1 side, and thereby a driver in the carrier 0 easily recognizes a deviation between the axial direction of the carrier 0 and the axial direction of the portal pallet 1 so that the collision between the carrier 0 and the portal pallet 1 can be avoided.
