An industrial truck includes a drive part with a drive frame and a load part. The load part includes a lift frame having a load frame, which includes a plate, a load-carrying means connected to the plate, and at least one bearing head configured to receive a lift cylinder. The at least one bearing head is connected to the plate.

The present disclosure relates to the technical field of lift trucks, and in particular, to an energy control method and system of a lift truck. The method includes the following steps: step 1, putting the lift truck in a working state, and downwards closing a work platform at a high place, wherein hydraulic oil in an upper lifting oil cylinder and hydraulic oil in a lower lifting oil cylinder start to flow back into a oil tank; step 2, driving a hydraulic element to rotate anticlockwise in the back flowing process of the hydraulic oil, wherein the anticlockwise rotation of the hydraulic element drives a motor to rotate anticlockwise to generate a reverse electromotive force, and the reverse electromotive force is rectified to output a direct current for energy recycling.
