Product Description and Benefits

A horizontal carousel is a “parts to picker”, semi-automated material handling solution that consists of a series of bins with configurable shelves which slide horizontally on an oval-shaped track.

The units are typically tied into a WMS so that when operators pick orders, inventory is tracked automatically.

A motor unit, a structure that houses the shelves, and doors / other safety equipment are the primary components of the carousel.

When considering the ROI of a Modula HC (typically 6-18 months), customers can attribute cost savings to 6 primary areas

  • Save Time

Depending on the specific unit (i.e., size, drive, picking accessories), the set-up of that unit (i.e., average picks each time a bin is presented), and the confirmation of pick time, an employee can achieve up to 550 lines per hour. 1 employee is needed for every pod of HCs.

  • Save Space

Dead space in traditional storage systems (i.e., shelving, racking) can be minimized with a HC. Individual shelves that are adjustable on 2″ increments enable operations to be set-up custom for their specific product.

  • Reduce Risks

Automatics safety cut-offs (i.e., doors) and the ergonomic design of the Modula HC put safety first. Parts are delivered directly to the operator so they do not have to move around / bend in the warehouse, reducing the possibility for injury and product damage

Increase Security

  • User profiles can be created, limiting access to certain bins to only select employees. The multitude of user authentication features enables security with almost any existing set-up. Every movement is automatically logged in the HC, allowing traceability when contradictions occurs

Improve Inventory Management

  • Since the units trace the movement of items – in and out – the tasks associated with inventory monitoring are all but eliminated. When leveraging the Modula Premium Software package, inventory control will tie directly into a company’s ERP

Improve Accuracy

  • With traditional warehouses, human errors are nearly unavoidable, and at a high enough volume / pick price, can become extremely costly. With the appropriate visual aid features, 99% accuracy can be achieved with a HC
