The utility model discloses a crawler-type forklift hydraulic system, which comprises a plunger type variable displacement pump and a proportional control multi-way reversing valve. An output pipeline of the plunger type variable displacement pump is connected into the proportional control multi-way reversing valve, a reversing valve in the proportional control multi-way reversing valve is connected to a high-speed running oil motor of a forklift, a gantry lifting cylinder of the forklift, a gantry tilting cylinder and a forward cylinder respectively and correspondingly. The plunger type variable displacement pump is used as a power hydraulic element, the proportional control multi-way reversing valve pump is connected with hydraulic actuating elements such as the pump, the motor, the cylinders and the like so that the integral forklift has strong power and fine safety and operability, and is easy to realize automatic control, standardization, universality and serialization; and the crawler-type forklift hydr
