Overhead Chain Conveyor Systems

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

Overhead chain conveyor systems from Hangzhou Ocean Industry are built for continuous, round-the-clock handling of light and medium parts in painting, assembly, warehousing and metal processing plants. A five-ton class UH-5075 chain runs inside an enclosed rail above the working floor, so parts travel overhead while forklifts and operators keep the floor clear.

Every overhead conveyor system is supplied as a complete package: enclosed-track conveyor chain, drive unit, counterweight or spring take-up unit, straight track, horizontal curves, turntable corners, incline and decline rails, inspection track, track flange plates, and the pendant or carrier that suits your workpiece. Four chain models cover different duty levels - UH-5075-S, UH-5075-HH, UH-5075-HV and UH-5075-HA - with single-point lifting weights of 35 kg to 50 kg and an operating temperature of up to 250 °C.

Where accumulation or buffering is required, we also build power and free overhead conveyors, enclosed rail conveyors, heavy duty hanging conveyors and tow line floor conveyors for the same production lines.

Chains

Five-ton Standard Model (UH-5075-S)

Chains specifically designed for suspended conveyors, featuring large angle bending capabilities for ease of installation and suitable for general applications.

Five-ton Heavy-Duty Horizontal Wheel chain (UH-5075-HH)

Standard horizontal wheels are upgraded to load-bearing models to enhance their load capacity and wear resistance, thereby extending their service life. These are suitable for production environments with multiple bends or higher temperatures.

Five-ton Heavy-Duty Vertical Wheel chain (UH-5075-HV)

By upgrading the vertical wheels to load-bearing types, the resistance generated when the chain passes through the lifting bend is reduced, enhancing its load capacity and wear resistance. This is suitable for production environments that involve frequent extension and retraction or higher temperatures.

Five-ton Extra Heavy-Duty chain (UH-5075-HA)

By upgrading both the horizontal and vertical wheels to load-bearing types, the chain's load capacity and wearing resistance is optimized to be the best in its class. This makes it suitable for production environments with very complex routing, heavier suspended loads, and higher temperatures.

Drive Unit

The principle is that the power output by the speed-regulating motor is transmitted to the driving track after being boosted by the reducer. The pawls on the driving track are used to move the conveying chain to make the chain move forward. The transmission is stable, with low noise and high reliability in transmitting power.

Caterpillar-Type Drive Unit

The principle is that the power output by the speed-regulating motor is transmitted to the driving track after being boosted by the reducer. The pawls on the driving track are used to move the conveying chain to make the chain move forward. The transmission is stable, with low noise and high reliability in transmitting power.

Sprocket-Type Drive Unit

The motor reducer outputs power to the sprocket and chain, which directly acts on the chain and the chain buckle, thereby driving the chain to walk. It has a simple structure, is compact, easy to install and adjust, and is suitable for conveyors with a shorter length.

Counterweight Take-Up Unit

The take-up unit keeps the conveyor chain correctly tensioned. It compensates for chain stretch under load and for the expansion and contraction caused by temperature changes, and maintains a moderate tension between the drive unit and the take-up unit. Generally, it is placed behind the drive unit at the place with the smallest tension. After tensioning, there should be no large downhill section with decreased load. Relying on the counterweight disk on this device, the tightness of the chain is automatically adjusted to ensure the normal operation of the drive unit. The tensioning force is relatively stable and has a wide range of applications.

Spring Take-Up Unit

The take-up unit keeps the conveyor chain correctly tensioned, compensating for chain stretch under load and for the expansion and contraction caused by temperature changes, and maintaining a moderate tension between the drive unit and the take-up unit. Generally, it is placed behind the drive unit at the place with the smallest tension. After tensioning, there should be no large load drop slope section. The structure is relatively compact and easy to install. However, since its tension is limited by the spring coefficient, it is generally suitable for occasions with shorter lines and little temperature change.

Straight track

Used at the horizontal straight line where the conveying chain travels. The standard supply length is 6 meters, and it can be cut to any length according to the installation site conditions.

Turntable Corner Track

The disc at the center can rotate 360° around the central axis. It is suitable for occasions with a small turning radius. It can reduce the frictional resistance generated when the chain passes through the elbow, and it is convenient to install and disassemble.

Horizontal curves

Used at the horizontal turning point where the conveying chain travels. The standard diameter ranges from 0.8 to 2 meters at 180°. It can be cut to any degree according to the installation site conditions. Horizontal elbows can also be customized and processed according to customer needs

Sleeve Track

The sleeve produced by our company is a compensation device designed to absorb the elongation and shortening of the track when the conveying line passes through an area with large temperature changes. It can be used as a take-up unit and can also be used at the connection of straight tracks in the furnace. The straight track can freely expand and contract within the sleeve, so it will not deform in an environment with thermal expansion and contraction.

Inspection Track

There is an opening that can open the track. Through this opening, the conveying chain can be disassembled, inspected and maintained. Each conveyor line's driving device should be equipped with an inspection track. It is generally located between the outlet of the drive unit and the take-up unit, at a place convenient for inspection and maintenance.

Incline and Decline Track

Used at the ascending and descending points where the conveying chain travels. It can be cut to any angle according to the installation site conditions, but the angle should not be greater than 45°. However, the influence of the distance between two adjacent pendants in ascending and descending should be considered.

Track Flange Plate

It is used for interconnecting two tracks to facilitate construction and maintenance. Use M10×20 bolts.

Y-shaped pendant

It is directly connected to the chain and has the characteristics of convenient and quick installation. Its lower end is often connected to a cross pendant or a cross disc pendant.

Single point pendant

It is directly connected to the chain and has the characteristics of convenient and quick installation. Its lower end is often connected to a cross pendant or a cross disc pendant.

U-shaped pendant

Suitable for a lower working environment and requires manual assistance for rotation. It can be positioned once every 90° of rotation.

Cross pendant

It needs to be used in combination with the Y-shaped pendant. When the chain is running, the cross support leg hits the pendant diverter installed at a specific position, which can make the suspended work rotate by 90°.

Cross disc pendant

The structure of the cross disc pendant is basically the same as that of the cross pendant, but an additional disc is added above the hook to catch the possible oil dripping in the track and prevent the workpiece from being contaminated.

Gear disc pendant

When the chain is running, the gear is used in conjunction with the rack fixed at a specific position, which can make the suspended workpiece rotate continuously.

Plating pendant

This pendant is specially designed for electroplating factories and is suitable for electroplating pendants.

C-shaped pendant

This pendant is specially designed for paint baking factories with higher requirements. An oil receiving groove can be installed in the middle to prevent dust from falling on the workpiece. The size can be customized according to customer requirements.

Bearing gear pendant

When the chain is running, the gear is used in conjunction with the rack fixed at a specific position, which can make the suspended workpiece rotate continuously. It is suitable for connection with a single-pendant chain.

Bearing pendant

It can rotate freely and is suitable for smaller work. It can be directly connected to the chain.

It can rotate freely and is suitable for connection with single-pendant chains.
