A 3-stop enclosed lift completely isolates the vertical transport path within a secure, custom-fabricated hoistway to move multi-ton payloads safely across three facility elevations. Open-shaft configurations in high-traffic or environmentally sensitive manufacturing zones expose personnel to moving carriage hazards and allow airborne debris to contaminate sensitive production materials during transit. Gradin engineers these heavy-duty SJD VRCs by integrating our rigid dual-mast lifting architecture with a fully interlocked steel-mesh or solid-panel enclosure, synchronized directly to the PLC and landing gates. This strict electromechanical architecture ensures the carriage cannot cycle unless all perimeter access points are mechanically sealed and verified. Every structural enclosure, carriage dimension, and guide rail profile is custom-engineered to match your facility’s exact floor-to-floor heights and strict safety compliance requirements.

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.
Seguro e confidencial: Sua proposta técnica e seu projeto 3D estarão prontos em 2 horas.
