Beschreibung
Zusammenfassung:	The invention discloses a full-hydraulic brake system for an electric forklift. The system comprises a hydraulic oil tank and an oil pump. An oil outlet of the oil pump is communicated with a port P of a brake charging valve, a port ACC of the brake charging valve is communicated with a port P1 of a power brake valve, a PBR port is communicated with a parking brake, a port T is communicated with the hydraulic oil tank, and a COOL port is communicated with a wet type drive axle through a radiator; a port P3 of the drive axle is communicated with the radiator, a port P2 is communicated with a port F of the power brake, a port T2 is communicated with the hydraulic oil tank, and the power brake valve is connected with a brake pedal of the electric forklift. The problem that in the prior art, abrake system of an existing large-tonnage electric forklift is not high in reliability and driving safety is solved, the brake reliability and driving safety of the electric forklift are remarkably improved, and the high pra
