Four Wheel Trolley

Hangzhou Ocean Industry Co., Ltd. is one of the most experienced manufacturers and suppliers of four wheel trolley in China. Welcome to wholesale customized four wheel trolley at competitive price from our factory. Good service and quality products are available.

The image above displays a complete painting conveyor line. The specific component we are highlighting is the trolley, a critical part of the system. At Hangzhou Ocean Industry, we supply a wide range of trolleys with various load capacities to suit your specific needs. These trolleys are essential for the smooth operation of your conveyor line. Furthermore, our engineers can provide custom designs tailored to your specific application scenarios to ensure you get the perfect fit.

The four wheel trolley of the suspension conveyor is a crucial part within the suspension conveying system. Its main function is to stably convey different kinds of materials on the overhead tracks. Thanks to its four - wheel design, it can offer superior balance and load bearing capabilities, making it applicable to a wide range of industrial production environments and logistics transportation situations.

We also offer a full range of trolleys to meet diverse application needs. From light-duty to heavy-duty options, we provide various configurations and accessories compatible with any conveyor system.

The three trolley models are X348, X458, and X678.

The four wheel trolley is connected to the track of the suspension conveyor through specially designed suspension connection parts. These connection parts are usually high-strength hooks, earrings or slot structures. The hook part is made by forging process and has high strength and toughness. It can bear the weight of the trolley and materials and ensure the tight connection between the trolley and the track during operation.

Choosing the correct trolley for your overhead conveyor system requires evaluating three critical factors. Follow this decision guide or contact our engineers for a free assessment.

Step 1: Load Calculation

Formula: Required Load Capacity = (Part Weight + Fixture Weight) × Safety Factor 1.5

For example: A 120 kg engine block with a 30 kg fixture → (120 + 30) × 1.5 = 225 kg minimum capacity, which calls for at least an X348 series trolley.

If your line has frequent starts and stops, multiply by 2.0 for dynamic shock loads.

Step 2: Track Compatibility

Measure your existing I-Beam flange width. The trolley wheel must sit securely on the beam without lateral play. Our X-series trolleys are compatible with standard Chinese (GB), European (EN), and American (ASTM) I-beam profiles.

Cross-reference your track spec with the compatibility column in the table above.

Step 3: Environment Check

• Wet / Corrosive? → Hot-dip galvanized + stainless bearings

• High Temperature (>150°C)? → All-steel wheels, high-temp grease

• Cleanroom / Food? → Nylon wheels + sealed bearings, no grease leakage

Uniform material loading: By distributing the weight of the materials on the track equally among the four wheels, excessive local stress can prevent track damage or unstable trolley operation. In addition to safeguarding the materials themselves, this uniform loading feature lessens damage brought on by unequal tension during transit.

Stable working performance: The trolley operates more smoothly on the track thanks to its four-wheel design. It is more resilient to outside influence than trolleys with two or three wheels. When moving materials with high stability requirements, such precise instruments, or operating at a fast pace, this stability is very crucial.

In industries such as machinery manufacturing and automobile manufacturing, it is used to transport large parts such as engine blocks and machine tool beds. It can also be used to transport semi-finished and finished products between different workstations in the workshop to improve production efficiency.

In large logistics warehouses and distribution centers, it is used to handle and transport various goods, including large packaged items and industrial equipment. Its stable performance and high carrying capacity can meet the logistics industry's demand for fast and safe transportation of goods.

In the food and beverage industry, it is used to transport packaged food and beverage products such as cases of beverages and bagged foods. Due to its stable operation, it can reduce vibrations and collisions on products and ensure the quality of products during transportation.

The body of the four wheel trolley provides a carrying platform. Its carrying capacity is determined by the structural strength of the body and the designed carrying range. When materials are placed on the trolley, the structure at the bottom of the body evenly distributes the weight to the four wheels. The four wheel trolley is connected to the track of the suspension conveyor through special suspension connection parts. These connection parts are usually hook, earring or slot structures. For example, in hook connection, the hook on the top of the trolley is hung on the suspension point on the track. The hook is generally made by forging process and has high strength and toughness, and can bear the weight of the trolley and materials. Speed control is mainly achieved by adjusting the speed of the drive motor.
