摘要： A forklift apparatus includes: an error prediction unit configured to predict a first positional error which is a positional error after picking-up between a standard position of a fork and a central position of a pallet on the fork after the pallet is picked up and a first angle error which is an angle error after picking-up with respect to the fork in the pallet; a travel route correction unit configured to correct a travel route from a picking-up position of the pallet to a stacking position of the pallet to offset the first positional error and the first angle error when the pallet is stacked; and a conveyance travel control unit configured to perform travel control such that the pallet is conveyed along the corrected travel route.

摘要： A position calculation system includes a managing unit managing a current position of a plurality of automated guided vehicles; and a position calculating unit calculating a position of the target automated guided vehicle based on a detection result, detected by the laser measuring device mounted on the target automated guided vehicle, of detecting each reflection light reflected from a specific number being two or more of reflection sources, position information of which is obtainable, existing at positions on mutually different directions viewing from the target automated guided vehicle. Here, when the reflection sources with the reflection light therefrom detected include a mounted reflection source mounted on another automated guided vehicle other than the target automated guided vehicle, the position calculating unit obtains the position information of the mounted reflection source based on the current position managed by the managing unit, and calculates a position of the target automated guided vehicle.

摘要： The forklift includes a lift bracket which is supported on a mast so as to be capable of being moved upward or downward along the mast, and a fork member having a fork claw portion on which a pallet is allowed to be placed, and supported on the lift bracket, wherein the lift bracket has a support portion which is formed on a tip portion of the lift bracket and which supports the fork member. When a weight is applied onto the fork claw portion, the fork member displaces around the support portion which is configured to serve as a pivot, in response to an application force exerted onto the fork claw portion.

摘要： A steam valve has a tubular stop valve configured to move toward an upper end side and a lower end side along an axial direction when the stop valve is opened and closed respectively; and a valve main body configured to accommodate the stop valve. The stop valve has a ring-shaped protrusion portion protruded outwardly in a radial direction. The valve main body has an accommodation space for accommodating the protrusion portion which is divided by the protrusion portion into a first pressure space and a second pressure space. First and second feed/discharge portions configured for adjusting a pressure in the first pressure space and the second pressure space respectively are further provided. The protrusion portion is moved upwardly and downwardly by adjusting the pressure in the first pressure space and the second pressure space.
