The invention provides a forklift portal oil way system and a forklift, and relates to the technical field of forklifts. The forklift portal oil way system comprises an oil way connecting-in pipeline, a lifting pipeline and an accessory pipeline. The oil way connecting-in pipeline is communicated with a multi-way valve of a forklift hydraulic system. The lifting pipeline is communicated with the oil path access pipeline; the accessory pipeline comprises two first chain wheels, two sets of accessory oil inlet duplex pipes, two first chains, two sets of accessory oil outlet duplex pipes, two hydraulic locks, two adapter valves, a chain wheel mounting block and a second chain, and the two first chain wheels are rotationally arranged on an inner door frame of the forklift and arranged in the width direction of the inner door frame at intervals. The accessory oil inlet duplex pipes in duplex pipe arrangement cover the sides, deviating from the first chain wheels, of the two first chains in a one-to-one correspondence mode, the accessory oil outlet duplex pipes cover the sides, deviating from the second chain wheels, of the second chains, the space occupied by the pipeline structure is greatly saved, the visual field range is greatly improved, and safety is improved.

    本发明提供一种叉车门架油路系统及叉车,涉及叉车技术领域。叉车门架油路系统包括油路接入管路、起升管路和属具管路,油路接入管路与叉车液压系统的多路阀连通;起升管路与油路接入管路连通;属具管路包括两个第一链轮、两组属具进油双联管、两个第一链条、两组属具出油双联管、两个液压锁、两个转接阀、链轮安装块和第二链条,两个第一链轮可转动地设置于叉车的内门架,并沿内门架的宽度方向间隔布置。通过采用双联管布置的属具进油双联管一一对应地覆盖于两个第一链条背离第一链轮的一侧,并将属具出油双联管覆盖于第二链条背离第二链轮的一侧,大大节省了管道结构所占用的空间,极大的改善了视野范围,提高了安全性。
