The invention discloses a control method and device for a heavy load type fork reach forklift, and the method comprises the steps that when a fork is below a first height, the forklift runs at a first running speed, accelerates at a first acceleration rate and decelerates at a first deceleration rate; between the first height and the second height, driving at a second driving speed, accelerating at a second acceleration rate, and decelerating at a second deceleration rate; when the vehicle is between the second height and the third height, the vehicle runs at a third running speed, accelerates at a third acceleration rate and decelerates at a third deceleration rate; at a third height or above, driving at a fourth driving speed, accelerating at a fourth acceleration rate, and decelerating at a fourth deceleration rate; a third height gt; a second height gt; a first height; a first driving speed gt; a second driving speed gt; a third driving speed gt; a fourth driving speed; a first acceleration/deceleration rate gt; a second acceleration/deceleration rate gt; a third acceleration/deceleration rate gt; and a fourth acceleration/deceleration rate. The swing amount of the portal frame is reduced when the pallet fork is located at a high goods position, and the stability of the forklift is improved.

    本申请公开了一种重载型货叉前移式叉车控制方法及装置,包括:在货叉第一高度以下时,叉车以第一行驶速度行驶,以第一加速率加速,以第一减速率减速;在第一高度与第二高度之间时,以第二行驶速度行驶,以第二加速率加速,以第二减速率减速;在第二高度与第三高度之间时,以第三行驶速度行驶,以第三加速率加速,以第三减速率减速;在第三高度以上时,以第四行驶速度行驶,以第四加速率加速,以第四减速率减速;第三高度>第二高度>第一高度;第一行驶速度>第二行驶速度>第三行驶速度>第四行驶速度;第一加/减速率>第二加/减速率>第三加/减速率>第四加/减速率。本申请减小了货叉在高货位时门架晃动量,增加了叉车稳定性。
