PROBLEM TO BE SOLVED: To provide a reach fork lift wherein the two-wheel drive of its front and rear wheels can be utilized effectively responding to its operational situation. SOLUTION: A reach fork lift has a first controller 51 for controlling the rotational direction and speed of rear wheels 13; and a second controller 53 for controlling the respective rotational directions and speeds of auxiliary motors 15, 16 of its front wheels 11, 12, based on the polarity and magnitude of a deviation signal e, between a rear-wheel speed specifying signal 56 obtained in the first controller 51 with respect to the rotational direction and speed of the rear wheels 13, and a feedback signal 57 obtained on the basis of the sensings of the respective rotational directions and speeds of the front wheels 11, 12. |
