Claims

[Claims for Utility Model Registration] 1. A vehicle chassis, a rear link that is pivotally connected near the rear end of the vehicle chassis and extends forward, an intermediate link that has one end pivoted to the front of the rear link and extends forward, and the intermediate link. A link mechanism frame consisting of a rising link whose base end is pivoted near the other end and rises upward, a container mounted on the chassis at the top of this link mechanism frame, and a pivot between the front part of the container and the upper end of the rising link. a locking device provided between the link mechanism frame and the bottom of the container that locks both and is unlocked by moving the container rearward relative to the link mechanism frame; and a locking device that rotates the rising link rearward. In a container handling vehicle that is equipped with a container retraction drive device that moves the container rearward and a dump cylinder that applies upward rotational force to the linkage frame, A container cargo handling vehicle characterized in that an operating circuit for operating a dump cylinder is provided with a detection switch that shuts off the operating circuit when the locked state and unlocked state of the locking device are not detected. 2. The detection switch that interrupts the operation circuit of the dump cylinder is placed between the normal rising position of the rising link and the position of rotating the rising link by a predetermined angle to the rear.
A container cargo handling vehicle according to claim 1, which is constructed by a switch that responds to the movement of a rising link so that a contact opens at a position other than the two positions. 3 A detection switch that cuts off the operating circuit of the dump cylinder is connected to a first contact that detects and closes when the container moves forward and is within a specified position range, and a first contact that detects and closes the switch when the container is not within the specified position range. a second contact parallel to the first contact;
a third contact in series with the first contact, adapted to close upon detecting a fully engaged condition of the locking device; and a third contact configured to close upon detecting that the locking device is not fully engaged; A container cargo handling vehicle according to claim 1, which is constituted by a fourth contact point in series with the second contact point.
