The invention relates to a traveling brake control method for a high-lift forklift. The traveling brake control method comprises the following steps: S1, judging the current traveling direction of the forklift and the current treading depth of a brake pedal; s2, if the vehicle advances and a brake pedal is slightly stepped, the forklift braking torque is set to be T forklift 1; s3, if the vehicle advances and the brake pedal is treaded heavily, the forklift braking torque is set to be Tforklift 2; s4, if the vehicle retreats and the brake pedal is slightly treaded, the forklift braking torque is set to be Tforklift 3; and S5, if the vehicle retreats and the brake pedal is treaded heavily, the forklift braking torque is set to be T forklift 4. When the high-lift forklift is in service braking, the service braking torque of the forklift is related to the running direction of the forklift, and the driving wheels or the bearing wheels are effectively prevented from being locked; meanwhile, the service braking torque of the forklift is related to the lifting height of the pallet fork, the problems that when the pallet fork is in a high position, the service braking strength is large, the whole truck braking impact is large, and the whole truck shakes seriously are avoided, and the safety of high-position operation is improved.
本发明涉及一种高起升叉车行车制动控制方法,包括以下步骤:S1.判断车辆当前行驶方向以及当前制动踏板的踩踏深度;S2.若车辆前进且制动踏板处于轻踏时,设置叉车制动力矩为T叉车1;S3.若车辆前进且制动踏板处于重踏时,设置叉车制动力矩为T叉车2;S4.若车辆后退且制动踏板处于轻踏时,设置叉车制动力矩为T叉车3;S5.若车辆后退且制动踏板处于重踏时,设置叉车制动力矩为T叉车4。本发明在高起升叉车行车制动时,将叉车行车制动力矩与车辆行驶方向相关,有效防止驱动轮或承载轮抱死;同时,还将叉车行车制动力矩与货叉起升高度相关,避免货叉在高位时,造成行车制动强度大、整车制动冲击大、整车晃动大,提高高位作业安全性。
