Reinventing Vacuum Handling Through Intelligent Compensation
The Sheet Metal Vacuum Lifting Factory Direct Sales program introduces the New Auto-Vacuum Compensation Cantilever Manipulator, representing a significant advancement in adaptive lifting technology. Traditional vacuum lifters maintain constant suction power regardless of load conditions. This new generation system actively monitors vacuum levels and automatically compensates for leakage, surface irregularities, and varying porosity—maintaining optimal grip without operator intervention.
This intelligence proves transformative when handling challenging materials. Perforated sheets, expanded metal, and plates with surface scale have historically required mechanical clamping or specialized lifting attachments. The auto-compensation system detects incipient vacuum loss and increases flow to maintain secure attachment, effectively handling materials previously unsuitable for vacuum lifting.
Designed for High-Volume Sheet Processing
High-volume sheet metal fabricators operate under relentless productivity pressure. Every second spent positioning lifting equipment, adjusting suction cup configurations, or verifying load security represents non-value-added time. The cantilever manipulator eliminates much of this waste through intuitive controls and instantaneous response to operator commands.
The vacuum system achieves full holding force within two seconds of cup contact, compared to five to eight seconds required by conventional systems. Release is equally rapid, with powered blow-off breaking the vacuum seal instantly rather than relying on slow natural leakage. These time savings accumulate substantially across hundreds of daily lifting cycles.
Structural configuration follows proven cantilever crane practice: a vertical column supporting a horizontal arm that pivots to cover a circular work envelope. Unlike standard cantilevers, however, this manipulator incorporates the vacuum accumulator within the arm structure itself, eliminating external hose runs and reducing the system’s floor footprint. The result is a cleaner, more compact installation that integrates seamlessly into existing workflow patterns.
Multiple Models for Varied Production Requirements
The product line encompasses multiple models calibrated to specific thickness and weight ranges. The HC-PR3015-300 handles plates up to 8mm thick and 300kg weight with eight 200mm suction cups. The HC-PR3015-500 increases capacity to 12mm thickness and 500kg weight using the same cup configuration. For heavier applications, the HC-PR3015-1000 accommodates 20mm plate thickness and 1000kg loads with ten 250mm suction cups.
Wider plate applications find solutions in the HC-PR4020 series, offering the same thickness and weight gradations with expanded width capacity. All models accept standard 1250 x 1250mm minimum sheet sizes, accommodating the vast majority of commercially available metal sheet dimensions.
Power options include both pneumatic and electric configurations. Pneumatic versions suit facilities with existing compressed air infrastructure and explosion-proof requirements. Electric models provide independent operation where compressed air capacity is limited or unavailable. Both configurations maintain the auto-compensation feature central to the system’s performance advantage.
OEM/ODM Services Extend Application Reach
Factory direct sales include comprehensive OEM and ODM services for customers requiring modified configurations. Original Equipment Manufacturing partnerships allow established industrial distributors to brand the equipment under their own names while maintaining Herochu’s engineering and manufacturing quality. Original Design Manufacturing services modify base configurations to meet unique application requirements.
These customization capabilities extend to suction cup compounds, beam lengths, control interface layouts, and safety system configurations. Customers requiring ATEX certification for explosive atmospheres, FDA compliance for food contact applications, or specialized surface protection for polished stainless steel receive engineering modifications addressing these specific needs.
Comprehensive Quality Certification
Every manipulator system carries CE certification confirming compliance with applicable European directives. ISO 9001 certification verifies the quality management systems underlying design, manufacturing, and testing processes. EU-type examination certificates provide independent third-party verification of safety system performance.
For customers serving regulated industries, manufacturers provide full documentation packages supporting audit and compliance requirements. Material certifications for load-bearing components, weld procedure qualifications, and non-destructive examination reports accompany each custom-engineered system. This documentation satisfies quality assurance requirements in automotive, aerospace, and medical device manufacturing.
