摘要： PROBLEM TO BE SOLVED: To provide a safety device conducting start-up inspection including a boom operating device, a controller and a position detecting sensor for a short time. SOLUTION: This safety device 40 comprises a main power switch 43, an operating device 23, a controller 41, and a hydraulic pressure supply switch 45. Within a specified time since electric power is supplied to the controller 41 by the main power switch 43, if an actuation command signal outputted from the operating device 23 is a signal for stopping a telescopic boom, an operating device determining circuit 53 is determined as normal, and later actuation of the telescopic boom by the operating device 23 through the controller 4 is accepted. If the actuation command signal outputted from the operating device 23 is a signal for actuating the telescopic boom, the operating device 23 is determined as abnormal, and an operating device alarm lamp 63 falls down to regulate the actuation of the telescopic boom.

摘要： PROBLEM TO BE SOLVED: To provide a safety device for a work vehicle for both a crane and high lift work, which is capable of preventing the tumbling of a vehicle body during the high lift work without narrowing an original allowable moving range during crane work. SOLUTION: In a crane mode, a crane work allowable moving range is set within a locus drawn by the tip part of a boom 13 when the boom 13 is operated to its maximum limit without tumbling a vehicle body 11 while a maximum allowable lifting weight is loaded on a crane device. In high lift work, mode, a high lift work allowable moving range is set within a locus drawn by the tip part of the boom 13 when the boom 13 is operated to its maximum limit without tumbling the vehicle body 11 while an allowable maximum loading weight is placed on a bucket 13. In either mode, when the position of the tip part of the boom 13 is shifted from the set allowable moving range, an alarming operation is carried out via a controller.

摘要： PROBLEM TO BE SOLVED: To perform an inspection before starting for a detection sensor of boom moment and a detection sensor of operation table moment without using a weight. SOLUTION: When a switch 31 of inspection before starting is operated, the safety device 30 rotates an operation table and a moment calculation circuit 49 calculates a moment element value of operation table in a vertical face including an axial line of the boom among operation table moments affecting the boom from an operation table side in accordance with detected values by an operation table moment detection sensor 70 and a rotation position sensor 73. If the moment element value of operation table exceeds an allowable range stored in a memory 51, an alarming buzzer 61 goes off. When the switch 31 of inspection before starting is operated, the safety device 30 extends the boom from a completely contracted states and if the moment value detected by the boom moment detection sensor 35 exceeds an allowable range stored by a memory 51, the alarming buzzer 61 goes off.
