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.

Untuk seri tugas berat ini, kami dapat merekayasa kapasitas beban hingga [300] ton, dengan dimensi platform dan ketinggian pengangkatan yang disesuaikan dengan lingkungan operasional Anda. Persyaratan yang melebihi matriks teknik standar kami akan menjalani Analisis Elemen Hingga (FEA) oleh tim teknik kami untuk memastikan kelayakan struktural sebelum mengajukan solusi.
Untuk memulai proposal rekayasa, mohon berikan data dasar berikut ini:
Kapasitas Beban Terukur
Ketinggian Pengangkatan Maksimum & Ketinggian Tertutup
Dimensi Platform (L x W)
Siklus Tugas (misalnya, siklus operasional per jam/hari)
Kondisi Lingkungan (misalnya, di dalam/luar ruangan, pencucian, tahan ledakan)
Batasan kedalaman lubang atau jarak bebas di atas kepala
Ya. Sistem kontrol dapat dilengkapi dengan protokol komunikasi standar (misalnya, Profinet, Modbus, Ethernet/IP) yang menggunakan [Siemens / Allen-Bradley / Omron] PLC. Hal ini memastikan sinkronisasi sinyal I/O yang mulus dengan konveyor hulu/hilir, unit AGV/AMR, dan ruang kontrol pusat Anda.
Setiap unit khusus menjalani Uji Penerimaan Pabrik (FAT) wajib sebelum pengiriman. Ini termasuk pengujian operasional berkelanjutan pada beban pengenal 100%, pengujian beban berlebih statis di [120% / 125%] kapasitas, dan pemicuan fisik dari semua kunci pengaman mekanis anti jatuh dan hidraulik. Dokumentasi FAT dan bukti video disertakan dalam paket rekayasa Anda.
Setelah persetujuan akhir dari gambar General Arrangement (GA), waktu tunggu produksi biasanya 4 hingga 8 minggu. Komponen struktural berukuran besar direkayasa dengan desain modular agar sesuai dengan kontainer pengiriman standar (20FT / 40HQ). Perakitan di tempat menggunakan koneksi flensa baut yang telah direkayasa sebelumnya dan colokan penerbangan tugas berat, yang secara ketat menghilangkan kebutuhan akan pengelasan di lapangan.
Kami menyediakan standar [12/24]-Garansi satu bulan yang mencakup rangka struktural dan komponen hidraulik/listrik utama. Untuk meminimalkan waktu henti operasional, satu set lengkap bahan habis pakai standar (misalnya, kit segel silinder, sakelar perjalanan, relai) dikirimkan bersama peralatan Anda. Selama masa garansi, suku cadang pengganti untuk kegagalan yang bukan disebabkan oleh manusia dikirim melalui pengiriman udara prioritas (DHL/FedEx) dalam waktu 48 jam.
Di luar garansi, kami menjamin dukungan teknik seumur hidup. Gambar CAD, skema kelistrikan, dan BOM (Bill of Material) peralatan khusus Anda diarsipkan secara permanen dalam sistem kami. Hal ini memastikan Anda menerima pemecahan masalah jarak jauh tanpa gangguan, panduan pemeliharaan, dan pencocokan suku cadang yang tepat untuk seluruh siklus hidup peralatan.
