Giới thiệu về Kệ VNA (Very Narrow Aisle Racking)
Kệ VNA (viết tắt của Very Narrow Aisle) là phiên bản nâng cấp đặc biệt của hệ thống [Kệ Selective]. Đúng như tên gọi “Lối đi rất hẹp”, điểm đặc biệt nhất của hệ thống này là khả năng thu hẹp tối đa diện tích dành cho xe nâng di chuyển, qua đó dành phần lớn diện tích mặt sàn để lắp đặt thêm các dãy kệ chứa hàng.
Đây là giải pháp “cứu cánh” cho các kho hàng có diện tích đất hạn chế nhưng lại có lợi thế về chiều cao (kho trần cao).
Thông số kỹ thuật ấn tượng
| Tiêu chí | Thông số kỹ thuật |
| Tải trọng | 1000 – 3000 kg/tầng |
| Chiều cao kệ | Rất cao (Có thể đạt 15m – 17m) |
| Chiều rộng lối đi | 1600mm – 1800mm (So với 3.5m của kệ thường) |
| Khả năng tiếp cận | 100% (Tiếp cận trực tiếp mọi pallet) |
| Xe nâng sử dụng | Xe nâng tháp (Turret Truck) hoặc VNA Truck |
| Hệ thống dẫn hướng | Ray cơ khí hoặc Dây dẫn từ (Wire guidance) |
| Dung sai mặt nền | Yêu cầu nền kho cực phẳng (Superflat floor) |
| Bảo hành | 5 năm |
Tại sao Kệ VNA là “Kẻ thách thức chiều cao”?
1. Tận dụng tối đa chiều cao kho
Nếu các loại kệ thông thường chỉ cao khoảng 6-8m, thì Kệ VNA Unirack có thể vươn tới độ cao 15-17m. Điều này giúp bạn nhân đôi, nhân ba sức chứa mà không cần mở rộng diện tích đất.
2. Tiếp cận 100% nhưng vẫn tiết kiệm diện tích
Thường thì bạn phải đánh đổi: Muốn tiết kiệm diện tích thì dùng [Kệ Drive-In] (nhưng khó lấy hàng). Muốn dễ lấy hàng thì dùng Kệ Selective (nhưng tốn diện tích).
Kệ VNA giải quyết cả hai: Vừa cho phép tiếp cận 100% pallet bất kỳ, vừa tiết kiệm diện tích sàn nhờ lối đi siêu nhỏ.
3. An toàn tuyệt đối nhờ Ray dẫn hướng
Do lối đi rất hẹp, việc xe nâng di chuyển cần độ chính xác cao. Hệ thống Kệ VNA được trang bị Ray dẫn hướng (Guide Rail) lắp dưới chân kệ.
Bánh xe của xe nâng sẽ chạy dọc theo đường ray này, giúp tài xế không cần lo lắng về việc va quệt vào giá kệ, chỉ cần tập trung vào việc nâng hạ hàng hóa.
Hệ thống yêu cầu sử dụng các loại xe nâng chuyên dụng có khả năng xoay càng 3 chiều.
So sánh Kệ VNA và Kệ Selective
| Tiêu chí | Kệ Selective | Kệ VNA (Lối đi hẹp) |
| Chiều rộng lối đi | 3.2m – 3.5m | 1.6m – 1.8m |
| Chiều cao tối đa | ~10m | ~17m |
| Diện tích sàn sử dụng | ~30% | ~50% |
| Chi phí xe nâng | Thấp (Xe nâng thông thường) | Cao (Xe nâng VNA chuyên dụng) |
| Yêu cầu mặt nền | Bình thường | Rất khắt khe (Cần độ phẳng cao) |
Những lưu ý quan trọng trước khi lắp đặt Kệ VNA
Để hệ thống VNA vận hành trơn tru, kho hàng của bạn cần đáp ứng 2 điều kiện tiên quyết:
- Mặt nền kho (Floor Flatness): Nền kho phải đạt độ phẳng cực cao (chuẩn Superflat). Vì khi nâng hàng lên độ cao 15m, chỉ một độ nghiêng nhỏ ở mặt sàn cũng có thể gây nguy hiểm lớn ở trên cao.
- Xe nâng VNA: Bạn phải chắc chắn ngân sách đầu tư cho xe nâng VNA (loại xe có người ngồi nâng lên cùng cabin hoặc xe càng xoay 3 chiều).
Báo giá hệ thống Kệ VNA Unirack 2025
Kệ VNA là giải pháp kỹ thuật cao, đòi hỏi sự chính xác trong khâu thiết kế và lắp đặt. Unirack tự hào là đơn vị có đủ năng lực thi công các hệ thống kệ siêu cao này.
