The invention relates to the technical field of forklifts, solves the problem that in the prior art, when a pallet fork forks goods and ascends to the position, the forklift tilts forwards or even tilts over, and particularly discloses a forklift structure with adjustable axle distance, and the forklift structure comprises a chassis system, a portal frame system and a driving system. When the fork ascends, especially when the fork picks up the load, the fork ascends and the center of mass ascends, when the center of mass ascends in the front part of the forklift, it is easy to cause the forklift to tilt forward or overturn, thus when the fork ascends to a first preset height, the front wheel is controlled to move forwards through the first driving assembly, so that the axle distance between the front wheel and the rear wheel is adjusted, the front supporting point is moved forwards, and the forklift is prevented from leaning forward. Besides,due to the fact that the fork ascends at the moment, the front wheels move forwards and do not interfere with the fork located at the low position.
本发明涉及叉车的技术领域,解决了现有技术中叉车在货叉叉取货物上升至会导致叉车前倾甚至倾翻的问题,并具体公开一种轴距可调的叉车结构,包括:底盘系统、门架系统以及驱动系统,由于货叉上升时,尤其是在货叉叉取了货物的时候,其上升会造成重心的上升,其重心上升的部分集中在叉车的前部时,容易造成叉车的前倾或者倾翻,则在货叉上升至第一预设高度时,通过第一驱动组件控制前轮的向前运动,以此来调节前轮与后轮之间的轴距,将前支撑点前移,防止叉车前倾,且由于此时货叉上升,前轮向前移动不会与处于低位置的货叉产生干涉。
