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 esta serie de alta resistencia, podemos diseñar capacidades de carga de hasta [300] toneladas, con dimensiones de la plataforma y alturas de elevación adaptadas a sus necesidades operativas. Los requisitos que excedan nuestra matriz de ingeniería estándar serán sometidos a un análisis de elementos finitos (FEA) por parte de nuestro equipo de ingeniería para garantizar la viabilidad estructural antes de proponer una solución.
Para dar inicio a la propuesta de ingeniería, por favor proporcione los siguientes datos de referencia:
Capacidad de carga nominal
Altura máxima de elevación y altura en posición cerrada
Dimensiones de la plataforma (largo x ancho)
Ciclo de trabajo (p. ej., ciclos operativos por hora/día)
Condiciones ambientales (p. ej., interior/exterior, lavable, a prueba de explosiones)
Restricciones relacionadas con la profundidad del foso o la altura libre
Sí. Los sistemas de control pueden equiparse con protocolos de comunicación estándar (por ejemplo, Profinet, Modbus, Ethernet/IP) utilizando [Siemens / Allen-Bradley / Omron] PLC. Esto garantiza una sincronización perfecta de las señales de E/S con las cintas transportadoras de entrada y salida, las unidades AGV/AMR y su sala de control central.
Cada unidad personalizada se somete a una prueba de aceptación en fábrica (FAT) obligatoria antes de su envío. Esto incluye pruebas de funcionamiento continuas a la carga nominal de 100%, pruebas de sobrecarga estática a [120% / 125%] capacidad, así como la activación física de todos los dispositivos mecánicos anticaída y los enclavamientos de seguridad hidráulicos. La documentación de la prueba de aceptación en fábrica (FAT) y el video de prueba se incluyen en su paquete de ingeniería.
Una vez aprobados definitivamente los planos del esquema general (GA), el plazo de fabricación suele ser De 4 a 8 semanas. Los componentes estructurales de gran tamaño se diseñan con una estructura modular para que quepan en contenedores de transporte estándar (20 pies/40 pies de altura). El montaje in situ utiliza uniones con bridas atornilladas prefabricadas y conectores de alta resistencia de tipo aeronáutico, lo que elimina por completo la necesidad de soldar en el lugar de la obra.
Ofrecemos un estándar [12/24]-meses de garantía que cubre el bastidor estructural y los componentes hidráulicos y eléctricos principales. Para minimizar el tiempo de inactividad, se envía junto con el equipo un conjunto completo de consumibles estándar (por ejemplo, kits de sellos para cilindros, interruptores de recorrido y relés). Durante el período de garantía, las piezas de repuesto para fallas no causadas por el usuario se envían por transporte aéreo urgente (DHL/FedEx) en un plazo de 48 horas.
Más allá de la garantía, te garantizamos asistencia técnica de por vida. Los planos CAD, los esquemas eléctricos y la lista de materiales (BOM) de su equipo personalizado se archivan de forma permanente en nuestro sistema. Esto garantiza que reciba asistencia técnica remota ininterrumpida, orientación sobre el mantenimiento y piezas de repuesto que se ajusten exactamente a su equipo durante todo su ciclo de vida.
🔒 Seguro y confidencial: Tu propuesta técnica y tu diseño en 3D estarán listos en 2 horas.
