The invention discloses a storage battery electric forklift integrating a hydraulic pump and a steering pump. The storage battery electric forklift comprises a lifting oil cylinder, a steering oil cylinder, a gear pump, a hydraulic oil tank and a driving motor, and the gear pump and the hydraulic oil tank are used for providing high-pressure oil for the lifting oil cylinder and the steering oil cylinder, and the driving motor drives the gear pump and is provided with a motor speed controller. A flow limiting reversing valve, a multi-way reversing valve and a steering gear are further included, the oil inlet end of the gear pump is connected with the oil outlet end of the hydraulic oil tank, the oil outlet end of the gear pump is connected with the flow limiting reversing valve, the multi-way reversing valve and the steering gear are both connected with the flow limiting reversing valve, the multi-way reversing valve and the steering gear are both connected with the oil return end of the hydraulic oil tank, the flow limiting reversing valve and the gear pump are both connected with the oil return end of the hydraulic oil tank in parallel, the lifting oil cylinder is connected with the multi-way reversing valve, and the steering oil cylinder is connected with the steering gear. The forklift is simpler in structure and reliable in work.
