Enclosed track overhead conveyors have been around for many years, some dating back to 1919 when they were used in automotive assembly plants. Simply described, enclosed track overhead conveyor is a series of trolleys with a load, suspended by an overhead track and connected to a continuous running chain, which can run winding both horizontally and vertically. Most people have seen them commonly used in a dry cleaning shop retrieving their dry cleaned clothing. However, this type of conveyor is not just for moving automotive parts or clean clothes. It provides a host of benefits, which I’ll talk about in a minute. But first, let’s look at the main components of this conveyor: the chain and the track. After which, I’ll review the key advantages and common issues that can occur with this type of conveyor.
The chain on an enclosed track overhead conveyor is made of formed C-1045 high carbon steel side bars connected in paired series with a drop forged 1045 high carbon steel pin. The 4-way pins allow for the chain to flex in both directions. Load wheels are assembled every 3rd pitch with side guide wheels on each alternate pitch.
The track is made of formed square tubular 1030 high carbon manganese steel complete with a jig welded yoke at each end, allowing for correct alignment when bolting the track together at installation.
Advantages of Enclosed Track Overhead Conveyor
Listed below are some of the main reasons this type of conveyor should be used as an economic solution to automate processes within a facility.
- Frees up floor space
- Takes goods to an operator
- Can change directions both in the vertical plain and horizontal plain
- Multiple drives allow for extended lengths
- No welding required for installation of the track
Things to Watch

Luckily, each of these items can be answered by working with qualified engineers on an acceptable resolution for successful design and implementation.
- Correct placement of drive and chain pull calculation
- Ample take-up and placement of take-up assembly
- Lubrication, either automatic or manual brush
- Possible contamination of track from ambient conditions
From its beginning in 1919 to its automation capabilities today, enclosed track overhead conveyor has established itself as a true, tried and tested form of material handling equipment. If you haven’t considered using it to establish an economical form of automation in your facility, it is worth a look.
