How Smart Accumulation Reduces Labor Strain

Workforce challenges remain a top-of-mind concern for distribution and fulfillment operations. Labor costs, turnover, and difficulty finding skilled workers are consistently listed as major logistics pain points by industry analysts like MHI and Gartner.

So how do warehouses maintain throughput without simply adding more people?

One of the most effective strategies lies in smarter conveyor system design — specifically, using zero-pressure accumulation where product must be held without contact, and leveraging minimal-pressure transport conveyors where a small amount of product contact is acceptable.

Why Accumulation Matters for Labor Efficiency

True accumulation conveyors are designed to stop and hold product without contact between items. This zero-contact capability allows products to queue safely without touching or creating back pressure.

In facilities where pickers and packers work at variable speeds, products naturally bunch up. Without proper accumulation, this can result in:

• Conveyor backups
• Bottlenecks
• Manual intervention
• Rework or product damage

Zero-pressure accumulation systems use zone-based control to:

• Control product flow
• Eliminate product-to-product contact during stops
• Reduce manual touches
• Maintain consistent throughput

This allows operators to focus on value-added tasks rather than clearing line congestion or monitoring flow.

Zero-Pressure Accumulation vs. Minimal-Pressure Transport

Zero-pressure systems are engineered to stop and hold product without contact. Individual zones sense product presence and operate independently, allowing items to queue safely.

This approach is ideal for:

• Delicate or high-value products
• Applications where surface damage must be avoided
• Operations requiring precise product release

Example: Hytrol’s E24™ 24-volt platform enables zone-controlled accumulation with intelligent control integration.

Minimal-Pressure (Low-Pressure) Transport Conveyors

Minimal-pressure conveyors — such as Hytrol’s ACC — are designed primarily as transport conveyors that move product with controlled, reduced pressure.

They can stop a line as a whole and reduce product force, but they do not provide true zero-contact holding. When the line stops, product may come into contact with the item ahead of it.

These conveyors are well suited for:

• General product transport
• Applications where slight product contact is acceptable
• Bulkier cartons where controlled movement is beneficial

Intelligent Control with EZLogic® and EZLogic® Net

Behind effective accumulation is smart control. Hytrol’s EZLogic and EZLogic Net provide zone-based logic that allows conveyors to respond dynamically to product movement. EZLogic enables independent zone operation, automatically stopping and starting sections based on product presence. EZLogic Net expands communication across multiple conveyor sections for coordinated system-wide flow control. The result is smoother throughput, reduced bottlenecks, and fewer manual adjustments — helping facilities maintain consistent performance even with fluctuating labor availability.

Labor Impact in Today’s Workforce Landscape

With staffing shortages still prevalent, operations are looking for ways to optimize output without increasing headcount.

Properly applied accumulation and minimal-pressure transport systems help by:

• Reducing manual touches
• Minimizing stoppages due to clogs
• Smoothing order flow during demand swings
• Improving shift-to-shift consistency

In many facilities, this translates to:

• Fewer overtime hours
• Faster onboarding (less conveyor supervision required)
• Improved ergonomics and reduced fatigue

Design Smarter, Not Harder

When you pair zero-pressure accumulation with thoughtful layout and intelligent controls (and use minimal-pressure transport where appropriate) you gain:

• Greater visibility into material flow
• Decreased burden on labor
• Improved product handling
• Higher throughput without workforce increases

The key is applying the right conveyor technology for the right function.

Workforce challenges are reshaping warehouse operations for the long term. Facilities that thrive are those that invest in smarter conveyor strategies using accumulation and transportation systems to best advantage.

Smarter systems don’t replace your people, but they can vastly amplify their productivity.
