Client Profile & Core Challenges
A major third-party cold chain logistics provider in Northern China, specializing in frozen meat and frozen food storage.
High Energy Costs: Frequent door openings for forklift operations caused significant cold air loss, leading to heavy electricity bills.
Low Operational Efficiency: Manual and forklift productivity dropped sharply in sub-zero temperatures, slowing throughput.
Elevated Safety Risks: Icy floors increased forklift slippage, posing risks to goods and personnel.
Poor Space Utilization: Wide aisles for forklift turning wasted valuable cold storage space.
Tianjin Master's Tailored Solution
We implemented a high-density Pallet Shuttle System specifically designed for their needs.
Core System Configuration:
Heavy-Duty Cold Storage Racking: Materials and finishes designed for low-temperature environments to ensure reliable cold storage inventory management.
Freezer-Ready Pallet Shuttles: Critical components use low-temperature steel and lubricants for reliable operation at -30°C.
Wireless Communication: Enables real-time data exchange without frequent door openings.
Intelligent WCS: Automatically dispatches shuttles and optimizes storage/retrieval sequences.
Redesigned Workflow:
Receiving: Forklifts place pallets at the aisle entrance conveyor; the shuttle automatically takes over and stores them in the deepest available location.
Dispatching: Upon WCS command, the shuttle retrieves target pallets to the aisle entrance, creating a "goods-to-forklift" model that minimizes wait time.
Inventory Control: The system tracks every pallet's exact location, supporting FIFO or LIFO strategies.
Results Delivered
The system delivered immediate and sustainable value:
Significant Energy Savings: Reduced door openings by over 70%, yielding substantial annual electricity cost savings.
Efficiency Leap: Achieved semi-automation, more than doubling throughput and easily handling peak demand.
Enhanced Safety & Accuracy: Drastically reduced intra-warehouse traffic, virtually eliminating product damage and accidents while achieving 100% inventory accuracy.
Massive Capacity Increase: Narrow-aisle design increased storage capacity by over 60% compared to traditional racking.
