Transfer and transportation of parts and items in industrial environments and factories face many complications, therefore a system called “Conveyor “is designed for solving these problems. Among conveyor preferences and advantages over the manual transportation are the followings:
- Saving in time and production cost
- Preventing damage to the parts during transportation
- No need for manual transportation and reduction of employment costs
- Increased additional space in factories and production rate
- No need for lift truck and therefore no noise pollution

Conveyors are designed in different types and each of them has its own features and privileges.Conveyorized powder coating systems are designed for higher volume operations.

The simplest overhead conveyor is a hand-push trolley system. It has load bars attached to trolleys that ride in a box-shaped track or on a beam. Load bar assemblies can be designed to hold loads of anywhere from 250 pounds to 4,000 pounds. Movement of the parts suspended from the trolley assembly is accomplished by an operator who pushes the trolley along the track. Usually, these systems do not have any elevation changes. Switches can be used to route the load bar through one of several powder booths or other discreet stations within the system. The switches, which look and act like railroad switches, are activated by the operator who pulls a cord to move the part onto the appropriate track. Parts stand motionless inside each station of the operation. These systems can provide excellent flexibility for the low-volume coater.

Selection depends mostly on the product size and weight. Each conveyor has a limit of weight that can be hung on each hanger point and a different chain pitch between available centers
