Trolley/Lean pipe workbench/Assembly line

Trolley, also known as a material handling trolley or logistics trolley, is a piece of logistics equipment specifically designed for transporting materials, semi-finished goods, and finished products within factories, warehouses, or other premises.

Structure and Materials

Castors: Available in diverse types, commonly manufactured from materials such as brass, grey rubber and PPU. Specifications primarily include fixed, flat swivel, flat swivel with brake, swivel with expansion mechanism, and swivel with expansion and brake, facilitating the movement and

positioning of trolleys.

Main Frame Materials: Comprising stainless steel, aluminium profiles, wire rods and wire mesh. Stainless steel offers corrosion resistance, suitable for high-hygiene environments; aluminium profiles provide lightweight strength; wire mesh trolleys, constructed from wire mesh and standard connectors, feature easy disassembly and flexible assembly.

Worktops: Manufactured from steel plate or chemical-resistant laminate. Some surfaces undergo special treatment for corrosion resistance and anti-static properties, catering to diverse operational requirements.

Classification

By anti-static properties: These may be categorised as anti-static trolleys and standard trolleys. Anti-static trolleys exhibit surface resistivity values ranging from 10⁶ to 10⁹ ohms, rendering them suitable for industries such as electronics where static sensitivity is critical; standard trolleys typically possess surface resistivity below 10⁶.

Classification by tray material: Primarily includes injection-moulded and metal types. Injection-moulded trolleys are lighter in weight and relatively lower in cost; metal trolleys offer higher strength and superior durability.

Function and Purpose

Material Handling: Enables the swift and secure transportation of diverse materials, including raw materials, components, and semi-finished products, thereby enhancing handling efficiency and reducing labour costs.

Storage and Classification: Certain trolleys feature tiered or compartmentalised structures, facilitating the categorised storage and management of

different materials. This ensures items are arranged in an orderly and organised manner, simplifying retrieval and access.

Process Optimisation: Strategic deployment of trolleys optimises production line layouts, minimises material handling time, shortens production cycles, and elevates manufacturing efficiency.

Quality Control: Within certain manufacturing sectors, trolleys also facilitate the transport of materials awaiting or having undergone inspection. This supports quality control and traceability protocols, ensuring product quality standards are upheld.

Application Scenarios

Production Line Distribution: On automated or semi-automated production lines, trolleys are employed to transport raw materials or components from warehouses to production stations, or to convey semi-finished goods to subsequent processes, ensuring uninterrupted production flow.

Warehouse Management: Within warehouses, trolleys facilitate material intake, dispatch, and stocktaking, aiding standardised and efficient warehouse operations while enhancing space utilisation and goods turnover rates.

Quality Inspection and Packaging: During quality control, trolleys transport materials awaiting inspection. In packaging operations, they convey finished goods from production lines to packaging areas, safeguarding product quality and integrity throughout handling.

Maintenance and Servicing: During equipment maintenance or fault rectification, trolleys transport essential tools, spare parts, and replacement components. This facilitates maintenance personnel's work and minimises equipment downtime.
