In a bulldozer (1), a controller (110) steers a crawler-type construction machine in either a differential steering mode or a pivot steering mode by controlling left and right steering clutches (40L, 40R), left and right steering brakes (50L, 50R), and a steering motor (80). When the angle cylinder (8) and the lifting cylinder (9) are driven when the steering motor (80) is steered, the controller (110) executes hydraulic oil amount control that reduces the amount of hydraulic oil supplied from the hydraulic pressure supply unit (100) to the steering motor (80) and increases the amount of hydraulic oil supplied from the hydraulic pressure supply unit (199) to the angle cylinder (8) and the lifting cylinder (9).

    在推土机(1)中,控制器(110)通过控制左右转向离合器(40L、40R)、左右转向制动器(50L、50R)以及转向电机(80),使履带式工程机械以差速转向模式以及原地转向模式中的某一种转向。控制器(110)执行工作油量控制,该工作油量控制在使转向电机(80)转向的情况下使角度缸(8)以及升降缸(9)驱动时,使从液压供给部(100)向转向电机(80)供给的工作油量减少,且使从液压供给部(199)向角度缸(8)以及升降缸(9)供给的工作油量增大。
