Product Description
Push Back Racking** () is a high-density, LIFO (Last-In, First-Out) storage solution designed for deep-lane pallet storage. It utilizes a series of nested carts on inclined rails, allowing pallets to be "pushed back" by subsequent loads, maximizing space efficiency while maintaining selective access.

#### **1. Structural Design**
- **Core Components**:
- **Carriage Carts**: Mobile platforms on inclined rails that hold pallets and slide backward when new loads are added.
- **Frame Structure**: Heavy-duty steel uprights and beams with integrated rail channels.
- **Braking Mechanism**: Hydraulic or mechanical stops to control cart movement and prevent overextension.
- **Loading Zone**: Single entry/exit point per lane for forklift access.
- **Material**:
- Hot-rolled steel with galvanized or epoxy coatings for durability.
- Carriages reinforced with wear-resistant rollers.
---
#### **2. Key Advantages**
- **High-Density Storage**: Stores 3-6 pallets deep per lane, reducing aisle space by up to 75%.
- **Selective Accessibility**: Direct access to each pallet lane (unlike drive-in systems).
- **LIFO Efficiency**: Ideal for bulk storage of homogeneous SKUs with moderate turnover.
- **Safety**: Braking systems prevent unintended cart movement; guardrails ensure load stability.
- **Scalability**: Modular design adapts to warehouse layout changes.
---
#### **3. Applications**
- **Beverage Industry**: Storage of bottled drinks, cans, or kegs.
- **Food Cold Storage**: Bulk pallets of frozen or perishable goods.
- **Manufacturing**: Raw materials (e.g., plastics, metals) with consistent SKUs.
- **Retail Distribution**: Seasonal products or promotional inventory.

#### **6. Installation & Safety Guidelines**
1. **Floor Preparation**: Ensure level, reinforced flooring to handle concentrated loads.
2. **Load Testing**: Verify cart glide resistance and brake functionality.
3. **Safety Features**:
- Install lane-end safety barriers.
- Label maximum lane capacity clearly.
4. **Maintenance**:
- Lubricate rollers and rails biannually.
- Inspect cart alignment and brake systems quarterly.
