Types of MHEs - Part 2

Live Roller Conveyor

*


Most common style found in manufacturing and distribution environments:

Lineshaft Conveyor



Individual rollers are driven by twisted conveyor belts coupled to a drive shaft that runs down the length of the conveyor frame, typically under slung to one side. This is very flexible style of conveyor known for it’s economies in motors required, accumulation zone capability and slave driven divert mechanisms. Very well suited to manufacturing work cell automation and divert intensive applications in warehouse and distribution environments.

Belt Driven Live Roller Conveyor (BDLR)–driven by a common flat belt running underneath the rollers, traditionally in fairly long straight runs. This style is generally used in transportation in warehouses where divert and accumulation requirements are minimal. Variations of accumulation styles are available and diverters are usually external and independently driven.




Chain Driven Live Roller Conveyor (CDLR) – driven by a roller chain that closely couples the rollers mechanically, one to another. Traditionally used with heavy loads where very positive drive is required such as pallet conveyance or handling metal components in mass.

Under-floor conveyor
– the material being handled is located in roll carriages that are conveyed forward by the 180° turned conveyor chain embedded in the floor.


Overhead chain conveyors

- consist of a continuous chain running on or in an overhead track, with the loads on carriers suspended from the track and moved by the chain.
-typically used to convey unit loads in a variety of industrial applications
- used to convey finished goods, raw materials, work in process, tooling, patterns and fixtures.



Automated Guided Vehicles

AGV Applications in Warehouses and Distribution Centers
- Powered driverless trolleys, which are guided by following an under-floor wire, which carries an electric signal, or by optically following a painted or plastic tape track laid on the floor.
- Suitable for frequent movement on set routes.
- Reduce manpower and increase productivity
- The future of automated warehouse




Some examples of AGV:
