Curve Conveyor

Curved Belt Conveyor

The shortest distance between two points is a straight line. Sometimes due to the constraints of space and other factors, the package cannot be transported in a straight line, and the direction needs to be adjusted. At this time, a Belt Conveyor System is required.

The Guanchao turning curve PVC Belt Conveyor adopts active belt drive technology. The system takes a long time from the initial failure of a component to the paralysis of the system. As soon as the conveying condition changes slightly, the sound of the conveyor will change. A service technician walking by a running curve can tell the condition of its branch by its sound, so component failure can be detected months or years before it actually fails, chain/belt. The belt-driven system of a tumbler is extremely durable because component failure is slow to affect, and it is also extremely reliable because it is extremely rare that there is no warning before a catastrophic failure occurs.


The operation principle of the turning belt is to use the gear to drive the special chain on the outer edge of the belt, and then drag the entire arc belt to run through the chain. In this case, the curved belt itself does not need to run under tension, and it will not be affected by changes in load, tension, temperature, and humidity to affect its performance. This engaging method of driving ensures continuous and reliable operation in harsh environment operation.


The main advantage of Belt Curved Conveyor is that all available floor space can be utilized, so they represent an efficient and cost-effective solution that does not impact the production line when space needs to be optimized. As a result, these systems can be used in a variety of industries, especially unit handling applications, including warehouses and distribution centers, manufacturing and packaging facilities, airports and the food industry.


High Speed Capability:

Max. Speed can reach 150M/MIN.

Low noise Operation:

The working plane and the upper rail are separated, and the gap in the middle can absorb noise.

Not affected by pollutants:

The chain of the China turning curve belt conveyor is fixed in the guide rail for transmission, so it will not deviate from the transmission direction due to the accumulation of contaminants.



Powertrain system:

#50 conveyor chain with belt attachment links.


2-ply black PVC-OP with 1A clipper lacing.

Frame assembly:

All 3mm iron plate welded and painted.


Standard made from 3mm iron plate. Side-guards over 300mm high have a 25mm angled out top flange. If no sideguards are ordered, a 50 mm sideguard will be provided on the outside radius.

GUANCHAO frequently builds curves with a speacial radius based on customers actual needs.


The turning curve belt conveyor is a kind of conveyor, which can realize horizontal transportation and inclined transportation. Curved belt conveyor is especially suitable for various assembly line connection and turning operations, and is suitable for a wide range of industries.

The turning curve belt conveyor adopts a small diameter idler, which is convenient for corner connection and flexible in direction. The supporting frame can be made of carbon steel, aluminum profile or stainless steel. The belt can be made of different materials and specifications according to performance requirements.

The turning belt adopts a variable frequency speed regulation motor or a stepless speed reduction motor, which runs stably and can realize programmed automatic operation.


Reliability of “chain/belt” turning curve belt conveyor

There is no substitute for reliability

  1. Conveyor function will not be affected by changes in load and environment;
  2. The belt does not need to adjust the precise belt tension and the precise position of the tapered reel for the normal operation of the belt;
  3. The belt will not be deflected by the accumulation of contaminants on the belt.

This China turning curve belt conveyor focuses on reliability, we will never compromise reliability for the pursuit of more beautiful, unnecessarily quiet, cheaper or simple to produce conveyors, if a conveyor fails, it is useless, so There is no substitute for reliability.


Active drive/slack belt drive technology

Operational reliability is characterized by the ability of a system to operate normally in different environments, and the time between identification of initial failure and maintenance to complete failure. If a change in environment or the failure of a component results in a momentary loss of system performance, or Worse, leading to a catastrophic system failure, then the “good” system is not reliable. The chain/slack belt drive system is extremely durable, the system takes a long time from the initial failure of a component to affect the system down, the sound of the conveyor will change as soon as the conveying condition changes slightly. An experienced service technician walking past a running turning curve belt conveyor can discern the condition of its branch from its sound, so component failure can be detected months or years before actual failure occurs the belt drive system of a chain/belt curve conveyor is extremely durable because component failure is slow to affect, and it is also extremely reliable because it is extremely rare that there is no warning before a catastrophic failure occurs.


A chain/belt curve conveyor is a simple and reliable design where the “slack” belt is dragged by the chain on the outer edge of the belt, the chain actively drives the drive sprocket instead of the head and tail pulleys driving the belt, and other designs do not need to consider the special requirements of China turning curve belt conveyor, just rely on the belt tension customary for straight conveyors. Our products have a long service life because the belts on the conveyor and conveyor components are “slack”, such as bearings, drive shafts and belt engagement with less stress, the belt is just a simple Bearing surface, so there is no need to use expensive “high-tech” conveyor belt material. This concept of chained/slack belts engaged with mechanical steel buckles is very beneficial and makes repairs simple, if a section of the conveyor belt is damaged then only the damaged part needs to be replaced. Unlike friction-driven conveyors, mechanical steel buckle-engaged or driven belts do not slip on the head and tail pulleys to cause damage, and steel-buckle-engaged conveyors do not require extensive disassembly when changing belts, and in the event of cargo jams, a friction-driven turning curve belt conveyor will pop the belt under the rollers and melt the drive reels, while a chain/slack belt drive system will still run fine for long periods of time.


The idea of the chain/belt system is simple, but it is not simple to manufacture, the perfect result we have always strived for is to develop a quiet, efficient conveyor that combines reliability and simple maintenance, only through high-quality, modern raw materials and precision manufacturing to achieve high performance.

Technical Parameters of  China turning curve belt conveyor

Tank installation

All-steel welded structure, the sides of the tank body and the sliding bed are made of 3MM, thick iron plates, and the outer radius of the tank is 9.5MM longer than both ends of the conveyor.


chain cover

Made of steel with mounting slots for quick and easy disassembly.


tank height

Standard height———-216MM;

The width of the conveying surface is more than 1 meter————-216/305MM;

The outer radius of conveying is greater than 2210MM———305MM;

Note: The height of the tank body can be customized according to the application needs.


Roller bearing

Our standard bearings are the PEER UCFT/UCFB200 series, all bearings are precision, rated, permanently sealed and housed in a cast iron flanged housing with grease nipples.


Head and tail sprockets

The #50 precision chain is equipped with special helical teeth and hardened steel sprockets, the height of the conveyor groove is designed according to the size of the sprockets.

27-tooth chain teeth—-the height of the groove body is 216MM;

40-tooth chain teeth—-the height of the groove body is 305MM;

40-tooth sprocket for high speed and large conveyors;


Head and tail wheels and axles

The head and tail wheels are easy to change due to the plug-in installation, especially in sealed spaces. The tapered head and tail wheels are made of heavy-duty steel. It does not drive the belt, so no lagging is required. Steel The bushing is welded at both ends after machining. The material of the head and tail axles is S45C steel that has been turned, ground and polished, and one end supports the drive to lengthen.
