What we supply

4-Way Pallet Shuttles for Ambient and Cold Storage

TTF TECH supplies 4-way pallet shuttle systems for high-density pallet storage. Battery-powered shuttles carry pallets along and across the racking lanes in four directions. Paired with vertical lifts and control software, the system stores and retrieves pallets without forklifts entering the racking.

Challenges

Storage Problems a 4-Way Shuttle Helps Solve

A 4-way shuttle removes most forklift aisles from the storage block, so more of the floor and height is used for pallets. It suits warehouses that are short of space, short of forklift drivers, or running cold rooms.

Warehouse is full, expansion is costly

Fewer aisles mean more pallet positions in the same footprint.

Forklift driver shortage

Shuttles handle storage and retrieval inside the racking.

Rack and pallet damage

±2 mm positioning, and no forklifts driving into the lanes.

Hard to staff cold rooms

Cold-storage models are rated for −25 °C to 0 °C.

One breakdown blocks a lane

Shuttles change lanes, so another shuttle can take over the task.

Options

Find the Right Shuttle Configuration

A 4-way shuttle system is built from shuttles, racking, lifts and control software. Select each part around your pallets, stock profile and operating temperature.

Ambient shuttle series

Slim, standard, heavy-duty and super heavy-duty shuttles for −10 °C to 45 °C. Select by pallet weight and rack design.

Cold-storage shuttle series

Models rated for −25 °C to 0 °C, for chilled and frozen stores.

Lifts and supporting equipment

Vertical pallet lifts, charging stations and pallet stacking units complete the storage system.

Comparison

4-Way Shuttle vs Conventional Pallet Racking

Selective racking gives direct access to every pallet but needs a forklift aisle for each row. A 4-way shuttle system removes most aisles and automates pallet movement, trading higher upfront cost for higher storage density and lower forklift dependence.

Factor	Selective racking	2-way shuttle	4-way shuttle
Storage density	Lowest	High	High
Forklift needed	For every move	To move the shuttle between lanes	Only at inbound and outbound points
Automation level	Manual	Semi-automated	Fully automated with WMS and WCS
Lane changes	Not applicable	By forklift	Automatic
SKU flexibility	Highest	Low, one SKU per lane	Medium to high
Upfront cost	Lowest	Medium	Highest

How it works

How a 4-Way Pallet Shuttle System Works

1
Task assigned
Your WMS sends a storage or retrieval order to the warehouse control system (WCS).
2
Shuttle dispatched
The WCS assigns a shuttle and plans its route.
3
Pallet handled
The shuttle lifts the pallet and travels through the racking.
4
Level changed
A vertical lift moves the pallet or shuttle between levels.
5
Stock updated
The location is reported back and stock is updated in the WMS.

Software and integration scope vary by project and are confirmed with the equipment supplier before purchase.

FAQ

Frequently Asked Questions

How is a 4-way shuttle different from a 2-way shuttle?

A 2-way shuttle travels along one lane and needs a forklift to move it to another. A 4-way shuttle changes lanes by itself.

How much weight can a 4-way pallet shuttle carry?

From 0.8 tonnes to 4 tonnes per pallet, depending on the model.

Can it be used in cold storage?

Yes. Cold-storage models are rated for −25 °C to 0 °C.

How much does a 4-way pallet shuttle system cost?

It depends on the number of shuttles, racking size and software scope. Send us your layout for a quotation.

Does it work with a WMS?

Yes. It connects to a WMS through a warehouse control system.

Can a 4-way shuttle be fitted into existing racking?

Existing racks must be checked for compatibility with shuttle rails, loads and tolerances. Conversion is not assumed.

What decides how many shuttles we need?

The number of pallets moved per hour, the lane layout and the number of levels. Send us your throughput and layout for a recommendation.

Is local after-sales support available in Malaysia?

Yes. TTF TECH is based in Malaysia and is your local point of contact for product enquiries and after-sales support. The service scope is agreed for each project.
