Abstract

The present invention relates to an electric forklift capable of self-loading, and more specifically, to an electric forklift capable of self-loading that is wirelessly electric and, in addition to a multi-stage lift configuration, allows the multi-stage lift configuration to drive backward onto the upper surface of the electric forklift body to load a lifted object onto the upper surface of the electric forklift body, and then drives to a destination electrically to unload the loaded object. The self-loading electric forklift according to the present invention is capable of wireless electric driving, thereby eliminating the need for a driver's seat. By utilizing the existing driver's seat space as a loading area for lifted cargo and configuring a multi-stage lift capable of forward and reverse driving, it is possible to lift and fully load cargo using a single forklift vehicle. Furthermore, it functions as a transport vehicle when loaded and, after transport to the destination is completed, the cargo can be lifted again through the multi-stage lift configuration for unloading. Consequently, this ensures the safety of the workforce and reduces the number and types of vehicles required to complete the work, thereby providing the effect of reducing overall operating costs.

Description

Self-loadable electric forklift The present invention relates to an electric forklift capable of self-loading, and more specifically, to an electric forklift capable of self-loading that is wirelessly electric and, in addition to a multi-stage lift configuration, allows the multi-stage lift configuration to drive backward onto the upper surface of the electric forklift body to load a lifted object onto the upper surface of the electric forklift body, and then drives to a destination electrically to unload the loaded object. Generally, a forklift is equipment used exclusively for loading and unloading cargo, and is also called a forklift. These forklifts are primarily used for transporting cargo in various industrial fields, as they are equipped with a mast installed vertically to the body frame, in addition to a body frame that includes a drive unit configured to enable the forklift to move, and a hydraulically lifting fork is provided on the mast, allowing cargo to be lifted and moved/loaded by this fork. However, for safety reasons in specific industrial fields, such conventional general forklift configurations cannot move loads (cargo) while they are in a forklifted state; instead, they only unload the cargo onto a transport configuration capable of carrying separate cargo. The said loads must be transported via said transport configuration, and after the transport is completed, a process is required to unload the cargo from said transport configuration to the unloading area using the forklift configuration again. This conventional technology had a problem in that a single forklift could not satisfy the requirements of safety regulations in specific industrial fields, so it had to be transported through a transport configuration capable of transporting separate cargo as described above. Therefore, to solve these problems, there is an urgent need to develop a configuration that enables the lifting and full loading of cargo with a single forklift vehicle, functions as a transport vehicle while loaded, and allows for unloading by lifting the cargo again via a multi-stage lift configuration after the transport to the destination is completed.
