The invention discloses a forklift lifting hydraulic oil circuit capable of regenerating descending potential energy. The system comprises a descending potential energy regeneration oil circuit, wherein the descending potential energy regeneration oil circuit comprises a high-pressure energy storage oil circuit and a low-pressure energy storage oil circuit which work alternately. The lifting hydraulic oil circuit can recover most forklift descending potential energy, so that forklift energy consumption is effectively reduced; the technical problems of high cost and high consumption caused by high installation power of an existing forklift are solved; the economical efficiency of the whole forklift is improved; the service life of the whole forklift is prolonged; and environmental pollutionis reduced.

    本发明公开了一种下降势能再生的叉车升降液压油路,其包括下降势能再生油路,所述下降势能再生油路中包括交替工作的高压蓄能油路和低压蓄能油路,该升降液压油路能回收大部分叉车下降势能,从而有效降低叉车能源消耗,解决了现有的叉车装机功率大导致的成本高、消耗高的技术问题,提升了叉车整机的经济性和使用寿命,且减少了环境污染。
