The invention provides a forklift potential energy recycling system. The forklift potential energy recycling system comprises a hydraulic driving module, a hydraulic control module and an energy recycling module. The hydraulic driving module comprises a lifting oil cylinder group and a three-position six-way electromagnetic directional valve, and the hydraulic power unit is communicated with the lifting oil cylinder group through the three-position six-way electromagnetic directional valve; the energy recovery module comprises a recovery oil cylinder group and a two-position two-way electromagnetic directional valve; a rodless cavity inlet of the recovery oil cylinder set is communicated with a rodless cavity inlet of the lifting oil cylinder through a two-position two-way electromagnetic reversing valve. A rod cavity of the recovery oil cylinder group is communicated with a rod cavity of the lifting oil cylinder through a two-position two-way electromagnetic valve; a rod cavity inlet of the recovery oil cylinder group is communicated with the hydraulic power unit through a two-position two-way electromagnetic directional valve; the hydraulic control module is used for recovering energy in the load descending process by selectively controlling combination between the three-position six-way electromagnetic directional valve and the two-position two-way electromagnetic directional valve. The energy utilization rate of the forklift can be effectively increased, and the service life of hydraulic system parts can be effectively prolonged.
