Welcome to wholesale customized qxg250 & 200 four wheel conveyor trolley with integrated hanger at competitive price from our factory. Good service and quality products are available.

In the architecture of a high-efficiency finishing facility, the trolley acts as the critical interface between the track and the workpiece. Hangzhou Ocean Industry Co., Ltd. presents the QXG250 and 200 series four-wheel trolley, a specialized carriage designed to bring superior stability to automated tracks. While standard two-wheel trolleys are susceptible to "yawing" under heavy or off-center loads, our four-wheel configuration utilizes a dual-axle design to distribute weight evenly across the rail. This is particularly vital for the painting line chain QXG250 conveyor chain, where consistent positioning is required for robotic spraying.

Whether you are operating a 200mm or 250mm pitch industrial conveyor system chain, this trolley ensures that the movement remains fluid and vibration-free. By integrating a fixed hanging plate chain directly into the trolley chassis, we eliminate the mechanical play often found in multi-part attachments. As a core component for any single guide conveyor chain layout, this four-wheel carriage is built to handle the rigorous duty cycles of a modern painting line, providing the robust foundation needed for a heavy duty conveyor chain to perform at peak capacity without the risk of derailment or uneven wear.

Quad-Axle Load Balancing: The four-wheel layout reduces the pressure on each individual bearing, doubling the life expectancy compared to 2-wheel variants on an industrial conveyor system chain.

Anti-Tilt Geometry: Engineered to prevent the "pendulum effect" during rapid starts and stops in a painting line environment.

High-Temperature Bearing Seals: Specifically designed by Hangzhou Ocean Industry to prevent grease leakage in drying ovens up to 220°C.

Reinforced Hanging Plate: The fixed hanging plate chain is forged or laser-cut for high dimensional accuracy, ensuring a perfect fit for diverse hooks and jigs.

Corrosion-Resistant Chassis: Every trolley undergoes an electrophoresis or zinc-plating process to resist the acidic vapors found in pre-treatment wash tunnels.

Engineering Selection Advice

When should you choose the 4-wheel version over the 2-wheel standard? Hangzhou Ocean Industry recommends the 4-wheel carriage if your workpiece has a surface area exceeding 1.5 square meters or if it weighs more than 30kg. The extra wheels provide the necessary lateral support to keep the single guide conveyor chain aligned within the track during high-velocity turns.

Applicable Environmental Conditions

Operating Temp: Continuous use up to 200°C; intermittent up to 250°C.

Atmospheric Suitability: Compatible with high-humidity powder coating booths and solvent-based liquid painting line zones.

Loading Symmetry: While the 4-wheel design is more forgiving, centric loading is still advised to maintain the longevity of the heavy duty conveyor chain.

Common Installation Best Practices

Track Gap Inspection: Ensure the track opening is consistent; a narrow gap will cause the four-wheel trolley to bind, potentially overloading the painting line chain QXG250 conveyor chain drive.

Wheel Lubrication: For high-temperature lines, ensure that only "non-drip" high-temp grease is used to avoid contaminating freshly painted workpieces.

Automotive Sub-Assemblies: Carrying engine parts and chassis components through automated industrial conveyor system chain routes.

Furniture Manufacturing: Stable transport for metal cabinets and shelving units in a high-throughput painting line.

Agricultural Machinery: Handling heavy tractor components on a robust heavy duty conveyor chain track.

The four-wheel trolley operates as the rolling carriage within an enclosed C-track. As the painting line chain QXG250 conveyor chain is pulled by the drive unit, it connects to the trolley via the center link. The four wheels (two on each side) run along the internal horizontal flanges of the track. The fixed hanging plate chain extends through the bottom opening of the track, providing a secure mounting point for the workpiece. The dual-axle design ensures that even if the load is nudged, the trolley remains seated flat against the rail, preventing mechanical "surging."
