Disrupting a linear production flow to move massive payloads between floors often forces facilities to rely on slow, manual forklift bottlenecks. Gradin designs and manufactures heavy-duty automated through-VRCs that function as a continuous vertical bridge, allowing materials to enter the lift on one side and exit directly out the opposite side on a different elevation. We custom-engineer the onboard transit decks—integrating heavy-duty motorized rollers, specialized chain transfers, or specific locking mechanisms—to perfectly synchronize with your existing horizontal line speeds and exact load dimensions. By tying directly into your facility’s PLC architecture, these pass-through lifts eliminate manual staging and keep high-volume manufacturing or distribution lines moving continuously across multiple levels.

FEA-Validated Structural Integrity for Continuous Linear Material Flow
Vertical logistics in an automated factory environment requires a structure that can manage massive dynamic forces during high-speed induction. Every Gradin Automated Through-VRC Systems installation undergoes rigorous Análise de Elementos Finitos (FEA) during the design phase to simulate these repetitive loading profiles.
Zero-Deflection Masts: We utilize reinforced high-tensile box-section steel engineered to maintain absolute structural rigidity at heights up to 35 meters.
High-Stability Carriage Assembly: Our lifting platforms are specifically reinforced to handle the lateral forces associated with automatic through-conveyors.
Dynamic Stability Control: This engineering-first approach ensures the system maintains absolute structural safety during high-speed transitions, protecting your cargo and the long-term reliability of your vertical material artery.
Precision Synchronization and Millimeter-Perfect Through-Docking Logic
In modern linear manufacturing, throughput is defined by the speed of the floor-to-floor transition. The Gradin Automated Through-VRC Systems utilize advanced synchronized drive technology combined with closed-loop feedback.
Synchronized Motion Control: Utilizing Siemens S7-1500 PLC logic, the VRC achieves perfectly smooth vertical transitions, eliminating the “bounce” or micro-vibrations found in standard goods lifts.
Millimeter Accuracy: High-resolution absolute encoders and laser distance sensors ensure the platform aligns with floor-level conveyors with an accuracy of ±1mm.
Through-Access Synchronization: Our control logic manages the timing of automated safety gates and conveyor rollers on both sides of the mast, providing a seamless linear material flow that integrates perfectly with your automated production line pulse.
Industry 4.0 Connectivity and Full Factory System Integration
Vertical logistics must function as a transparent, data-driven node within your facility ecosystem. Every Gradin Automated Through-VRC Systems installation features an open-architecture control system designed for full digital integration.
Real-Time WMS Handshake: Through Profinet, EtherCAT, or 5G connectivity, the VRC communicates directly with your Warehouse Management System, receiving missions and reporting real-time status updates.
Autonomous Operational Logic: The system can be programmed to autonomously manage pallet buffering, sequencing, and multi-level distribution without human intervention.
Predictive Maintenance Monitoring: The system tracks chain/cable tension, motor torque profiles, and cycle health, providing the data needed to prevent unplanned downtime in high-stakes 24/7 automated facilities.
[E-commerce & Fulfillment] – High-Throughput Multi-Story Logistics
The Challenge: Moving thousands of pallets or picking bins vertically while maintaining a straight-line horizontal flow to maximize picking speed.
Gradin Solution: O Gradin Automated Through-VRC Systems act as the high-speed vertical artery within your fulfillment center. The 180° through-access allows for a linear “In/Out” workflow, significantly reducing pallet-wait times and increasing total facility throughput.
[Automotive & Manufacturing] – Multi-Floor Assembly Line Integration
The Challenge: Moving heavy engine sub-assemblies or multi-ton die sets between production floors without breaking the linear material flow.
Gradin Solution: Our Bespoke Heavy-Duty Through-VRCs provide the high-capacity vertical link required for Just-in-Time (JIT) manufacturing. By delivering components directly from one side of the lift to the other at the next level, the system eliminates manual handling and optimizes the production tact-time.
[Logistics & Warehousing] – Seamless Building-to-Building Material Flow
The Challenge: Moving temperature-sensitive cargo between disconnected buildings or mezzanines in restricted factory corridors.
Gradin Solution: We customize these units with weather-resistant shielding and insulated enclosures. The automated through-access turns a complex logistics bottleneck into a synchronized, automated material flow that maintains the integrity of high-value cargo throughout the vertical transition.
Redundant Safety Architecture and Precision Motion Monitoring
Safety in high-tonnage, automated vertical logistics is our most critical engineering priority.
Active Anti-Fall Redundancy: Every Gradin Automated Through-VRC Systems installation is integrated with redundant mechanical anti-fall gears and hydraulic velocity fuses that lock the carriage instantly if a failure is detected.
Intelligent Through-Access Protection: The PLC features active collision-avoidance logic, using laser sensors to verify both the entry and exit paths are clear before motion is triggered, ensuring zero structural damage during automated cycles.
Interlocked Safety Enclosures: We provide synchronized high-speed power gates that perform a digital handshake with the VRC, ensuring that vertical transitions are fully isolated from personnel, meeting the most stringent global safety ratings (ISO 13849-1 / CE).
Para essa série para serviços pesados, podemos projetar capacidades de carga de até [300] toneladas, com dimensões de plataforma e alturas de elevação personalizadas de acordo com seu envelope operacional. Os requisitos que excederem nossa matriz de engenharia padrão serão submetidos a uma análise de elementos finitos (FEA) por nossa equipe de engenharia para garantir a viabilidade estrutural antes de propor uma solução.
Para iniciar a proposta de engenharia, forneça os seguintes dados de linha de base:
Capacidade de carga nominal
Altura máxima de elevação e altura fechada
Dimensões da plataforma (C x L)
Ciclo de trabalho (por exemplo, ciclos operacionais por hora/dia)
Condições ambientais (por exemplo, interno/externo, lavagem, à prova de explosão)
Restrições de profundidade do poço ou de espaço aéreo
Sim. Os sistemas de controle podem ser equipados com protocolos de comunicação padrão (por exemplo, Profinet, Modbus, Ethernet/IP) utilizando [Siemens / Allen-Bradley / Omron]. PLCs. Isso garante uma sincronização perfeita do sinal de E/S com transportadores upstream/downstream, unidades AGV/AMR e sua sala de controle central.
Toda unidade personalizada passa por um teste obrigatório de aceitação de fábrica (FAT) antes do envio. Isso inclui testes operacionais contínuos com carga nominal de 100%, testes de sobrecarga estática com [120% / 125%] e o acionamento físico de todas as travas de segurança mecânicas antiqueda e hidráulicas. A documentação FAT e a prova de vídeo estão incluídas em seu pacote de engenharia.
Após a aprovação final dos desenhos de arranjo geral (GA), o prazo de fabricação normalmente é de 4 a 8 semanas. Os componentes estruturais de grandes dimensões são projetados com um design modular para caber em contêineres de transporte padrão (20FT/40HQ). A montagem no local utiliza conexões de flange aparafusadas pré-projetadas e plugues de aviação para serviços pesados, eliminando rigorosamente a necessidade de soldagem em campo.
Fornecemos um padrão [12/24]-A garantia de um mês cobre a estrutura e os principais componentes hidráulicos/elétricos. Para minimizar o tempo de inatividade operacional, um conjunto abrangente de consumíveis padrão (por exemplo, kits de vedação de cilindros, interruptores de deslocamento, relés) é enviado junto com o equipamento. Durante o período de garantia, as peças de reposição para falhas não induzidas por humanos são enviadas por frete aéreo prioritário (DHL/FedEx) em 48 horas.
Além da garantia, garantimos suporte de engenharia vitalício. Os desenhos CAD, os esquemas elétricos e a lista de materiais (BOM) do seu equipamento personalizado são arquivados permanentemente em nosso sistema. Isso garante que você receba solução remota ininterrupta de problemas, orientação de manutenção e correspondência exata de peças de reposição durante todo o ciclo de vida do equipamento.
