Giới thiệu hệ thống Kệ Push Back (Push Back Racking)
Kệ Push Back là hệ thống lưu trữ pallet mật độ cao, được thiết kế để tối ưu hóa không gian bằng cách lưu trữ hàng hóa theo chiều sâu (từ 2 đến 4 pallet).
Điểm đặc biệt nhất của hệ thống này là sử dụng các bộ xe trượt (carts) xếp chồng lên nhau trên một đường ray nghiêng. Khi nạp hàng, sức đẩy của xe nâng sẽ đẩy các pallet cũ lùi về phía sau để nhường chỗ cho pallet mới. Khi lấy hàng, nhờ trọng lực, các pallet phía sau sẽ tự động trượt ra vị trí ngoài cùng.
Thông số kỹ thuật Kệ Push Back Unirack
| Tiêu chí | Thông số kỹ thuật |
| Tải trọng | 1000 – 3000 kg/pallet |

| Độ nghiêng ray | Khoảng 3 độ |
| Màu sắc | Xanh – Cam (Sơn tĩnh điện tiêu chuẩn Châu Âu) |
| Xe nâng sử dụng | Các loại xe nâng phổ thông (Forklift, Reach Truck) |
| Bảo hành | 5 năm |
Nguyên lý hoạt động “Đẩy và Trượt”
Hệ thống hoạt động dựa trên nguyên tắc LIFO (Last In – First Out) – Vào sau Ra trước:
- Nhập hàng (Push): Pallet đầu tiên được đặt trên xe trượt trên cùng. Khi nhập pallet thứ 2, xe nâng sẽ đẩy pallet thứ 1 lùi lại phía sau, pallet thứ 2 sẽ nằm trên xe trượt phía dưới. Cứ thế tiếp tục cho đến pallet cuối cùng.
- Xuất hàng (Flow): Khi bạn lấy pallet ở ngoài cùng ra, trọng lực sẽ làm cho các xe trượt phía sau tự động trôi nhẹ nhàng về phía trước để lấp vào chỗ trống.
Toàn bộ hệ thống được xử lý bề mặt bằng công nghệ sơn tĩnh điện giúp chống rỉ sét và tăng độ bền.
Ưu điểm vượt trội so với Kệ Drive-In
Mặc dù cùng là kệ mật độ cao và tuân theo nguyên tắc LIFO, nhưng Kệ Push Back có những ưu điểm khiến nhiều doanh nghiệp sẵn sàng chi tiền nâng cấp từ [Kệ Drive-In]:
1. An toàn hơn cho người và xe
Với Kệ Push Back, xe nâng KHÔNG CẦN chui vào trong lòng kệ. Tài xế chỉ cần đứng ở lối đi chính để thao tác. Điều này giảm thiểu tối đa rủi ro va chạm giữa xe nâng và khung kệ, bảo vệ an toàn cho hệ thống.
2. Khả năng tiếp cận tốt hơn (Selectivity)
Nếu như Kệ Drive-In bắt buộc bạn phải lấy hết hàng ở tầng dưới mới lấy được tầng trên (cùng 1 làn), thì Kệ Push Back cho phép bạn tiếp cận độc lập từng tầng. Mỗi tầng (level) là một hệ thống trượt riêng biệt.
- -> Rất phù hợp nếu bạn có nhiều mã hàng (SKU) khác nhau ở các tầng khác nhau.
3. Tốc độ xuất nhập nhanh hơn
Do xe nâng không phải di chuyển sâu vào trong kệ nên thời gian xếp dỡ hàng hóa được rút ngắn đáng kể.
Ứng dụng thực tế
Kệ Push Back Unirack đặc biệt phù hợp cho:
- Kho hàng có diện tích chật hẹp nhưng giá trị hàng hóa cao.
- Kho hàng đông lạnh (cần tối ưu diện tích lạnh).
- Các doanh nghiệp Logistics cần tốc độ luân chuyển nhanh hơn Drive-In.
Nếu bạn cần lưu trữ hàng hóa tải trọng nhẹ hơn hoặc hàng thùng carton, hãy tham khảo giải pháp [Kệ Carton Flow] của chúng tôi.
Báo giá lắp đặt Kệ Push Back 2026
Chi phí đầu tư Kệ Push Back thường cao hơn Kệ Selective do hệ thống xe trượt và ray dẫn hướng phức tạp. Tuy nhiên, độ bền và hiệu quả vận hành mà nó mang lại là hoàn toàn xứng đáng.
