Description

Technical Field

[0001] This utility model relates to the field of lifting platform technology, and in particular to an extendable structure for a lifting platform. Background Technology

[0002] A lifting platform is a type of lifting machinery used for vertically transporting people or goods. It's a specialized device that achieves vertical lifting through hydraulic, electric, or mechanical drives, primarily used to address material handling, personnel operations, or obstacle-free passage needs at different heights. It also refers to equipment used for vertical transport in logistics systems such as factories and automated warehouses. Lifting platforms are often equipped with various horizontal conveying devices as connecting devices for conveyor lines at different heights. They are generally hydraulically driven, hence the name hydraulic lifting platform. Besides transporting goods at different heights, they are widely used for high-altitude installation and maintenance operations. The free-lifting characteristic of lifting platforms has led to their widespread application in municipal maintenance, dock and logistics center cargo transportation, and construction decoration. Equipped with car chassis or electric vehicle chassis, they can move freely, changing their working height and space. They offer advantages such as light weight, self-propelled operation, electric start, self-supporting legs, simple operation, large working area, and the ability to overcome obstacles for high-altitude operations, as well as 360-degree free rotation.

[0003] Existing lifting platforms have a small footprint, but the platform area is limited, which restricts the amount of goods that can be transported at one time, affecting work efficiency. The extension structures added to existing lifting platforms are unsupported, making them prone to damage when the goods are heavy. Existing lifting platforms cannot fix the support structure, resulting in poor stability of the support structure and poor support effect for the extension plates, which affects the service life of the lifting platform.
