Abstract:
1. A traction control device of a construction machine comprising a braking mechanism provided to each of wheels, the traction control device controlling the braking mechanism, the traction control device comprising: a rotation speed detector that detects a rotation speed of the wheels; a vehicle speed acquirer that acquires a vehicle speed of the construction machine; a control-start determiner that determines whether or not to control the braking mechanism based on the rotation speed; a control deviation calculator that calculates a control deviation based on the rotation speed and the vehicle speed; a traction force estimator that estimates a traction force transmittable from at least one of the wheels to a road surface; and a braking mechanism controller that controls the braking mechanism based on the control deviation calculated by the control deviation calculator and the traction force estimated by the traction force estimator, wherein the traction force estimator comprises:
