Heavy Duty Overhead Conveyor Line

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

XT series heavy-duty overhead conveyors are widely adopted among conventional overhead conveyor systems. Featuring a high degree of mechanization and automation, they are primarily applied to production processes with numerous connecting working procedures, short tact times and relatively stable processing methods.

The conveyor boasts excellent spatial adaptability, enabling arbitrary rotation in both the horizontal and vertical planes. With a well-designed routing layout tailored to process requirements, it can travel over long distances, bypass obstacles, and transport workpieces to designated locations along predefined paths for material handling. It connects separate, individual specialised production stations into an automated assembly line, lifting productivity, improving product quality and strengthening production management.

Additionally, the system can continuously carry workpieces through high-temperature ovens, toxic gas zones, powder coating booths, pre-dip painting pretreatment zones, freezing chambers and other hazardous areas to complete manufacturing operations difficult for manual labor. This greatly improves working conditions for operators.

Moreover, the XT series features low power consumption, low noise, stable operation, simple operation and safe usage.

Because the chain pivots freely in both the horizontal and vertical planes, the overhead conveyor is not tied to a single straight run. It can climb, descend, turn and loop back on itself, which means the track can be routed around pillars, ducts, cranes and other fixed obstructions instead of forcing the layout to fit the building.

The practical benefit is a conveying system that links isolated workstations into one continuous automated line. Workpieces arrive at the right station at the right moment, manual transfer between departments is eliminated, and the whole production flow becomes easier to schedule and control.

1. Traction Chain - XT Forged Chain

The die-forged chain is the traction element that drives the entire overhead conveyor. For the XT80 / XT76.2 and XT100 models, two chain variants are offered, and both can pivot freely in the horizontal and vertical planes - the property that lets the overhead conveyor follow tight two-plane curves without dedicated corner units.

P = pitch, C = clearance range, a = minimum curve angle; please refer to the technical drawing for the exact definition of each code.

2. Carrier Trolley

Each trolley runs inside the track and carries the workpiece, the spreader and the chain. It supports the vertical load, absorbs the resultant force produced by chain tension inside every vertical bend, and keeps the chain on the designed track line. Where the distance between two loaded carriages exceeds roughly 800–900 mm, an additional load carriage can be inserted in the intermediate space to raise the carrying density of the overhead conveyor.

Dimension codes A–E follow the trolley drawing; please refer to the confirmed drawing for exact tolerances.

3. Track & Temperature Expansion Rail

The track is built from ordinary I-beam sections and carries the trolley and chain above the working area. Where the overhead conveyor route crosses a hot zone such as a baking or curing oven, temperature expansion joints must be fitted at both ends of that section: one end is welded firmly to the track, the other is a sliding sleeve that mates with the adjacent rail. The defined clearance between the two rails absorbs thermal deformation, protects the track system and keeps the overhead conveyor running smoothly.

Temperature Expansion Rail

For continuous operation through ovens, freezing chambers and other thermally active zones, expansion rails are essential. One end is welded to the track and the other forms a sliding sleeve that interfaces with the next rail; an appropriate clearance is kept between the two rails so that thermal expansion and contraction are compensated, preventing track damage and ensuring smooth movement of the overhead conveyor.

Continuous running through hostile zones is what separates the XT overhead conveyor from simple conveying equipment. Typical working environments include:

• High-temperature baking, curing and drying ovens
• Toxic gas, fume and vapour zones that must stay sealed off from operators
• Powder coating booths and spray areas
• Pre-dip painting and surface pretreatment lines
• Freezing chambers, chill rooms and cold stores
• Multi-station assembly lines linking welding, coating, drying and packing

In each case the overhead conveyor takes over work that is difficult, unhealthy or unsafe for manual labor, which improves working conditions for operators as well as consistency of output.

• Model - XT80 / XT76.2, XT100 or XT160, selected from load, line length and curve count
• Track layout - horizontal curves, vertical bends, inclines, multi-level loops and obstacle bypass
• Speed - five predefined speed steps per model, or a variable-frequency drive for adjustable output
• Drive arrangement - drive and chain take-up positions adapted to the line route
• Carriers - hangers, spreaders and fixtures designed around your workpiece
• Heat-resistant build - expansion joints and suitable materials for oven and cold-store sections

Chains and trolleys are die-forged and heat treated, then checked for pitch accuracy, hardness and breaking load before assembly. The whole production process is run under the ISO 9001 quality management system, and non-standard configurations are engineered to order when a standard model does not fit the process.

Buyers receive layout and installation drawings, engineering support during the project and after-sales service once the overhead conveyor is in operation.

Hangzhou Ocean Industry Co., Ltd. manufactures and exports a complete range of chains, sprockets, gears, gear racks, V-belts, pulleys, timing pulleys, couplings, machined parts and overhead conveyor systems.
