Claims

[Scope of utility model registration request]

(1) A calculation means for calculating the packet tip position of the excavation construction machine, an area setting means for setting an area where the advance of the packet tip is prohibited, and a packet tip position calculated by the calculation means and the area setting means Comparing means for comparing with a set area and outputting a signal indicating that the packet leading end position has entered the set area; and determining that the packet leading end enters the prohibited area based on the output signal of the comparing means. A safety device for excavating construction machinery, comprising a means for preventing.

(2) The excavating device according to claim 1, wherein the calculation means calculates the packet tip position based on the lengths and inclination angles of the boom, arm, and packet, and the turning angle of the boom. Safety equipment for construction machinery.

(3) The area setting means is configured to prevent a collision between the 8-kett and the belly belt or a part that supports the aircraft body corresponding to the belly belt or the aircraft body;
An excavating construction machine according to claim 1 of the utility model registration claim, which sets the area immediately below the crawler track or the part that supports the machine body corresponding to the crawler track as an area into which the tip of the eight bucket is prohibited. safety equipment.

(4) The means for preventing the packet tip from entering the prohibited area prohibits the supply of hydraulic pressure to at least each working machine hydraulic cylinder in a direction in which the packet tip enters the prohibited area. A safety device for an excavating construction machine as set forth in claim (1) of a certain utility model registration.
