Title:
LOAD HANDLING REGENERATION SYSTEM FOR BATTERY TYPE INDUSTRIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2006/090709
Kind Code:
A1
Abstract:
A load handling regeneration system in the lift device of a battery type industrial vehicle capable of supplying a hydraulic oil to the other hydraulic actuators during regenerating operation by a simple structure and providing excellent regenerating efficiency. A hydraulic motor (6) driven by receiving a pressure oil from a lift cylinder (1) is interposed in a pipeline (20) for recovering the pressure oil from the lift cylinder (1) to a pressure oil reservoir tank (8) through a control valve (10). The hydraulic motor (6) is connected to an electric motor (4) driving a hydraulic pump (3) supplying the pressure oil to the lift cylinder (1) through a one-way clutch (7) transmitting a drive torque from the hydraulic motor (6) only to the electric motor (4).
