Your Design For Your Needs

No company has more expertise in the specialist design and build of hydraulic Lifting Deck Trailers — sometimes known as Moving Deck Trailers — than Don-Bur.

We invented Lifting Deck Trailer technology in the late 1980s, and our extensive experience has resulted in the most evolved, reliable, safe, and cost-effective solution available today.

Don-Bur's innovative Lifting Decks now dominate the major fleets, where each tailored design plays a critical role in operational success.

This success is underpinned by a culture of continuous improvement, driven by strong customer partnerships and a deep understanding of the ever-evolving logistics landscape. By staying closely aligned with operator needs and industry challenges, Don-Bur ensures its Lifting Deck solutions remain ahead of the curve.

“We have a longstanding working relationship with Don-Bur, who are extremely adept at understanding real-world logistics challenges and have developed new and exciting technology for us. Jointly, we’ve designed and engineered more efficient trailers for an ecologically sustainable future.”

Q: What Are Lifting Deck Trailers?

A: Double Deck trailers are now commonplace — especially in trunking operations. However, loading a traditional double tier trailer typically requires specialist lifting equipment, which can slow down operations and reduce flexibility.

A Lifting Deck Trailer — sometimes referred to as a Moving Deck Trailer — solves this problem by incorporating a hydraulically operated second platform. This full-length or rear three-quarter-length platform can be loaded at standard loading bay floor height and then raised at the push of a button, allowing a second payload to be positioned on the main floor beneath it.

This smart design not only speeds up loading but also doubles the available pallet space. While a standard trailer typically carries 26 UK pallets, a Lifting Deck Trailer can accommodate up to 52 UK pallets — effectively transporting two trailer loads in one.

Single Ram & Pulley System

Unlike some multi-ram designs, Don-Bur’s proven single ram and pulley system delivers a smooth, uniform lift — regardless of how the upper floor is loaded. This robust setup reduces stress and flexing on the trailer structure, enhancing reliability and long-term durability.

“Our work with Don-Bur over several years has given us the reassurance that such a sensitive and critical project would be done within a strict time-frame and shrouded in complete secrecy. We are delighted with the productive partnership and quality of work.”

— John Lewis Partnership

52 UK Pallet Capacity

Don-Bur was the first in the industry to introduce a Lifting Deck Trailer capable of carrying 52 UK pallets — a full 26 pallets per floor level.

When paired with Don-Bur’s ultra-thin 7.5mm 'Blade' panel, the trailer achieves a consistent internal upper floor width of 2440mm along the full length of the tub. This maximised internal space allows two full rows of UK pallets to be positioned side by side on both levels, without compromise.

Wedge Lifting Decks

Don-Bur ‘Wedge’ Lifting Deck Trailers — a type of Moving Deck Trailer — provide full-height loading on both upper and lower decks. This design enables generous aperture height clearances of up to 1928mm (6' 4"), making them ideal for high-cube freight without compromising volume.

All Wedge models retain Don-Bur’s class-leading 52 UK pallet capacity, making them one of the most space-efficient Moving Deck Trailer solutions available.

“We are excited about the introduction of Don-Bur's latest design of Lifting Deck trailer to our fleet. Safety and sustainability are paramount to us, and this trailer's advanced features align perfectly with our commitment to ensuring the highest standards in transportation.”

Temperature Controlled Lifting Decks

For operators in chilled or frozen distribution, Don-Bur offers fully temperature-controlled Lifting Deck Trailers — also referred to as Moving Deck Trailers — that maximise pallet volume while maintaining precise climate control.

The 3D video below demonstrates the robust construction and insulation methods used in our double deck temperature-controlled trailers, designed for performance and efficiency across both decks.

Enhanced Safety Features

To ensure the highest standards of safety, our lifting deck trailers are fitted with multiple fail-safe mechanisms. These are designed to prevent unintentional lowering of the upper platform — even in the event of mechanical failure. Safety features include:

1. Rope Arrest / Brake Bar Mechanism

Each column slide plate includes a robust, sprung-loaded horizontal brake bar. A vertical steel rod runs through the brake bar, and if lift support from the cables is lost, the bar automatically twists against the rod, jamming the deck securely in place within just 50mm of travel (including 25% FOS).

2. High-Strength Support Cables

The lifting mechanism uses 4 or 6 steel fibre cables, each rated to support up to 20,897 kg. This ensures exceptional load-handling and structural integrity under real-world operational stresses.

3. Hydraulic Burst Valve

To protect against hydraulic failure, the system is fitted with a burst valve. In the event of a ruptured pipe, the valve immediately isolates the circuit to prevent any unintended movement.

4. Sprung-Loaded Safety Paddle Locks

When the upper level is raised, four sprung-loaded paddle locks engage beneath it, providing additional mechanical restraint and further safeguarding against unplanned descent.

5. Flow Control Valve

This valve regulates the hydraulic fluid flow, ensuring a controlled and steady lowering speed of the upper floor level.

By combining these engineered safety systems, our lifting deck trailers — and moving deck systems in general — offer dependable performance with built-in peace of mind for operators and depot staff alike.
