- Page 15 3.If the truck can’t lift goods normally. For example. the truck with 1.5T loading capacity but can only lift goods less than 1T, then we can adjust the oil pump pressure to reach 1.5T loading capacity. But the operation must be carried out carefully. P.S.: Don’t adjust the hydraulic pressure exceed the rated load.
