Abstract

The invention provides a power supply system of a gantry crane. The system comprises a battery pack used for driving a first motor of a cart running gear, a second motor of a dolly running gear, a third motor of a lifting mechanism, and other electrical systems of the gantry crane. According to a technical scheme of the invention, the battery is used to supply power for the gantry crane, thereby increasing mobility of the gantry crane, getting rid of dependence on diesel and reducing energy consumption. The invention further provides the gantry crane using such power supply system.

Description

technical field

[0001] The invention relates to the field of engineering machinery, in particular to a power supply system of a gantry crane and a gantry crane with the power supply system. Background technique

[0002] Among the current construction machinery, the power source is mainly obtained from the diesel engine on the equipment. For example, the tire-type container gantry crane is the main operating machine in the container storage area, and its power source is also a diesel unit.

[0003] The power supply scheme of the traditional rubber-tyred container gantry crane is a diesel generator set for power generation, and the output load is divided into four routes. The first three roads are respectively used by frequency converters such as equipment hoisting mechanism, trolley mechanism, and cart mechanism, and the other road is used by equipment manufacturers for lighting, control and other auxiliary equipment after passing through the isolation transformer. Since the...
