An object of the present invention is to provide a new load measuring apparatus for a construction machine that enables more enhancing measurement precision by monitoring a condition of a suspension cylinder. The load measuring apparatus for a construction machine according to the present invention is provided with a loading weight arithmetic module 111 that calculates a loading weight on the basis of loads of plural suspension cylinders 51 and a loading weight confirmation module 112 that outputs the calculated loading weight when the loads of the suspension cylinders 51 are all equal to or larger than a specified value and makes the calculated loading weight ineffective without outputting the loading weight when any one of the loads is below the specified value.

A device for measuring weight on board may include a sensor mounter coupled to a shackle, a first motor mounted to have a same rotation center as a first rotation center of the shackle being connected to the vehicle body, a second motor mounted to have a same rotation center as a second rotation center of the shackle being connected to an eye of the spring, a first angle sensor rotating by receiving torque of the first motor, and a second angle sensor rotating by receiving torque of the second motor, in which a rotation angle of the shackle about the first rotation center may be measured by the first angle sensor, and a rotation angle of the shackle about the second rotation center may be measured by the second angle sensor, and weight on board may be measured depending on variation of the rotation angle of the shackle.

Systems for estimating an axle load of a vehicle wherein axle load is estimated in response to an angle between two components of an axle. The angle may change as weight is added to or removed from the axle such that axle load may be determined as a function of the angle.
