Technical details and manufacturing context for Trolley Frame

Definition

The trolley frame is the primary structural component of a trolley, serving as the foundational framework that determines the overall shape, dimensions, and load-bearing capacity of the trolley. It provides mounting points for wheels, handles, shelves, baskets, or other attachments, and is designed to withstand the stresses of loading, movement, and maneuvering. In the context of fabricated metal product manufacturing, this component is typically produced from steel, aluminum alloy, or stainless steel, with material selection based on required strength, weight, and corrosion resistance. The frame's design—whether welded, bolted, or tubular—ensures structural integrity and stability during use. It transfers the weight of the loaded contents and any applied forces (e.g., pushing, pulling) through its members to the wheel axles and ultimately to the ground. Key parameters include load capacity (150–500 kg, evenly distributed, per GB/T 10486), frame material (Q235B carbon steel, optional stainless steel, per GB/T 700), tube wall thickness (1.5–2.5 mm, per GB/T 3094), overall dimensions (800–1200×500–800×800–1000 mm, customizable), wheelbase (500–700 mm), frame weight (15–30 kg), surface treatment (powder coating, per ISO 12944), weld quality (full penetration welds, no defects, per EN 15085), tolerance (±2 mm, per ISO 2768-m), and operating temperature (-20–60°C). These values are reference ranges and must be verified for the specific model and application. The frame is a component, not a standalone product, and its suitability depends on the intended trolley type and usage conditions. Buyers should confirm all specifications with the legal manufacturer or supplier before procurement.

Working Principle

The frame functions as a rigid structural skeleton. It transfers the weight of the loaded contents and any applied forces (e.g., pushing, pulling) through its members to the wheel axles and ultimately to the ground. Its design (e.g., welded, bolted, tubular) ensures structural integrity and stability during use. The frame's geometry and material properties determine its load-bearing capacity and resistance to bending, torsion, and fatigue. Proper load distribution is critical; uneven loading can cause stress concentrations and premature failure. The frame also provides mounting points for wheels, handles, and other attachments, which must be aligned to ensure smooth movement and maneuverability. During operation, the frame experiences dynamic loads from movement over uneven surfaces, which must be considered in design. Regular inspection for cracks, deformation, or weld defects is necessary to maintain safety and performance.

Frequently Asked Questions

What materials are available for the trolley frame?

According to the product data, the frame can be made of steel, aluminum alloy, or stainless steel. The specific material grade listed is Q235B carbon steel, with stainless steel as an option. The choice depends on the required strength, weight, and corrosion resistance for the intended application.

What is the load capacity of this trolley frame?

The load capacity is specified as 150–500 kg, with the note that it is for static load and evenly distributed. This is a reference range per GB/T 10486, and the actual capacity for a specific model must be confirmed with the manufacturer.

What standards apply to the trolley frame?

The product data references several standards: GB/T 10486 for load capacity, GB/T 700 for material, GB/T 3094 for tube wall thickness, ISO 12944 for surface treatment, EN 15085 for weld quality, and ISO 2768-m for tolerance. These are verification references, not proof of certification.

Can the dimensions be customized?

Yes, the overall dimensions are listed as customizable per customer, with a reference range of 800–1200×500–800×800–1000 mm (L×W×H). Other parameters like wheelbase and frame weight are also variable. Always confirm exact dimensions with the supplier.
