摘要： PROBLEM TO BE SOLVED: To provide a safety device of a high lift work vehicle capable of grasping the load on a sub boom of a temporary supporting device in a correct state, and preventing, based on the grasped load, breakage of the temporary supporting device and the toppling of a car. SOLUTION: The horizontal load Fx in the derricking plane along the derricking plane of a sub boom 55 applied to a fore-end part (a load application point 56a) of the sub boom 55 while holding a cable by a cable holder 56 is detected by an in-derricking-plane horizontal load detector 82. The horizontal load Fy outside the derricking plane orthogonal to the derricking plane of the sub boom 55 is detected by an outside-derricking-plane horizontal load detector 83. The vertical load Fz applied to a fore-end of the sub boom 55 is detected by a vertical load detection means 90. When at least one of the horizontal load Fx in the derricking plane, the horizontal load Fy outside the derricking plane, and the vertical load Fz exceeds the allowable values Fxa, Fya and Fza set corresponding to each load, the operation of the sub boom 55 and the operation a main boom 30 are regulated.

摘要： PROBLEM TO BE SOLVED: To accurately stop a steered wheel at the target steering angle position even in a range where the steering angle of the steered wheel is large. SOLUTION: A controller 50 actuates a steering cylinder 17 so that the steering angle of a front wheel 11a detected by a steering angle detector 62 follows the target steering angle of the front wheel 11a set according to an operation state of a steering dial 42. The controller 50 calculates the size of the steering angle of the front wheel 11a based on the detection information from the steering angle detector 62. When the size of the steering angle is not larger than the predetermined reference amount, the controller actuates the steering cylinder 17 at a first actuation speed, and when the size of the steering angle exceeds the reference amount, the controller actuates the steering cylinder 17 at a second actuation speed which is lower than the first actuation speed.

摘要： PROBLEM TO BE SOLVED: To allow the movement locus of a traveling body to meet a target locus, when the rotary traveling direction is reversed. SOLUTION: A traveling control device is constituted to perform control for operating a steering cylinder 17, to allow the rudder angle of front wheels 11a (wheels to be steered) detected by a rudder angle detector 62 to follow the target rudder angle of the front wheels 11a, which is set in response to the operating state of a steering dial 42. The target rudder angle of the front wheels 11a (wheels to be steered) which is set in response to the operation state of the steering dial 42 is compared with the detection rudder angle of the front wheels 11a detected by the rudder angle detector 62. When the difference between the target rudder angle and the detection rudder angle is not lower than the prescribed value, the traveling speed of the traveling body 10 is restricted to allow the traveling speed of the traveling body 10 to be not higher then prescribed speed.
