What is automatic crate pushing?

Automatic crate pushing is a material handling technology that uses mechanical pusher arms and conveyor systems to move plastic crates through production and storage facilities without manual intervention. These systems integrate with existing conveyor lines to automatically transfer, sort, and position crates, reducing labour costs and improving operational efficiency. The technology is particularly valuable in high-volume environments where consistent crate movement is essential for maintaining production flow.

What is automatic crate pushing and how does it work?

Automatic crate pushing technology uses pneumatic or electric pusher arms mounted alongside conveyor systems to move plastic crates from one line to another or into specific positions. The basic mechanism involves sensors that detect approaching crates, triggering pusher arms to extend and guide crates onto parallel conveyors, into storage areas, or towards processing stations.

The system integrates seamlessly with material handling workflows through programmable logic controllers (PLCs) that coordinate timing between conveyors and pushers. When a crate reaches a predetermined position, sensors signal the pusher mechanism to activate, moving the crate precisely where needed. This automation eliminates the need for workers to manually lift, carry, or position heavy crates throughout the facility.

Modern automatic crate pushing systems can handle various crate sizes and weights, with adjustable pusher speeds and forces to accommodate different products. The technology works particularly well with modular conveyor designs, allowing facilities to configure multiple push points along production lines for optimal material flow.

Why do companies choose automatic crate pushing over manual handling?

Companies adopt automatic crate pushing primarily to reduce labour costs and improve worker safety by eliminating repetitive lifting and carrying tasks. The technology provides consistent throughput regardless of staffing levels, while reducing workplace injuries associated with manual crate handling in high-volume operations.

The automation delivers enhanced operational efficiency by maintaining steady material flow without the variability inherent in manual processes. Workers can focus on value-added tasks such as quality control and product preparation rather than spending time moving crates between stations. This reallocation of human resources often results in improved overall productivity.

Automatic systems also provide better inventory control and tracking capabilities. Integration with warehouse management systems allows real-time monitoring of crate movements, enabling more accurate stock management and reducing the risk of misplaced or lost containers. The consistent handling also minimises damage to both crates and products during transport.

What types of facilities benefit most from automatic crate pushing systems?

Food processing plants, distribution centres, and manufacturing facilities handling large volumes of plastic crates gain the most benefit from automatic pushing systems. These environments typically process hundreds or thousands of crates daily, making manual handling both costly and physically demanding for workers.

Facilities with space constraints particularly benefit from the technology’s ability to maximise floor area utilisation. Automatic systems can move crates through tight spaces and into storage positions that would be difficult for workers to access safely. This is especially valuable in food processing, where hygiene requirements limit worker movement in certain areas.

Operations requiring consistent timing and flow rates find automatic crate pushing essential for maintaining production schedules. Retail distribution centres, beverage production facilities, and pharmaceutical manufacturing often depend on precise material timing to prevent bottlenecks. The automation ensures steady crate movement regardless of shift changes or varying worker availability.

How does automatic crate pushing integrate with existing conveyor systems?

Automatic crate pushing systems integrate with existing conveyors through modular mounting brackets and standardised control interfaces that connect to current PLCs or automation systems. Most installations require minimal modifications to existing belt, roller, or chain conveyors, with pusher mechanisms mounted alongside conveyor frames.

Space requirements typically include 500–800 mm of clearance beside the main conveyor for pusher arm travel, plus access for maintenance. The systems work effectively with various conveyor types, though roller conveyors often provide the smoothest crate transitions. Integration with sorting systems requires coordination between pusher timing and diverter mechanisms to ensure accurate crate routing.

Compatibility considerations include crate dimensions, weight limits, and conveyor speeds. Most automatic pushing systems accommodate standard plastic crate sizes while handling weights up to 25 kg per crate. Advanced systems can integrate with storage solutions like LT Storage systems, creating comprehensive automated workflows that manage crates from receipt through storage to dispatch without manual intervention.

The technology represents a practical step towards facility automation, offering immediate benefits while providing a foundation for future material handling improvements. Proper integration ensures reliable operation and positions facilities for continued efficiency gains as production demands grow.
