Back to case studies

The Client

Boots is the UK’s leading pharmacy-led health and beauty retailer, with over 2,500 stores in the UK. The company, which is part of the Walgreens Boots Alliance group, committed itself to converting its entire UK and Ireland trunking fleet to fixed double deck trailers in 2008, saving an estimated 14 million miles p.a. As part of its continuous improvement programme, in 2014, Boots asked Transdek to look at ways to further improve the efficiency of its conventional, stepframe double deck trailer fleet.

What We Did

The aim was to produce a new form of double deck trailer that would carry more load than Boots’stepframe fleet, provide a more stable driving experience, and address the increased safety and theft risks of barn doors being opened in the yard before docking.

To achieve the extra payload capacity, we combined the designs of conventional straightframe and sloping chassis trailers. With a 76mm ultra slimline neck and horizontal decks over the 5th wheel, the new Wedge design gave up to 1737mm clearance over the neck on each deck. Behind the neck, both the floor and second deck slope away to the rear of the trailer, giving increased loading clearance.

At the rear of the trailer, our V-Glide sash type door were designed specifically to be opened after docking. Twin, counter weighted composite panel doors slide independently in slimline vertical columns set in to the rearframe.

The Results

Boots ordered its first 65 Wedge trailers in 2016. Each Wedge trailer carries 128 rollcages, 23% more than the 108 carried on its stepframe trailers. The extra load has enabled Boots to reduce its trunking fleet from 340 to 280 trailers. Drivers have reported improved stability on the road, with the Wedge’s improved weight distribution over the 5th wheel. By keeping the rear doors sealed until after docking, Boots has also reported increased loading speed and safety, and improved product security.


"With the introduction of our first innovative Wedge trailers from Transdek we are aiming to save on average 1,092 trunks a year, which would cut up to 348,000km (216,000 miles) from our routes. These significant savings support our goal to deliver retail products from our warehouses to Boots stores as efficiently as possible. As a responsible retailer, we are continually working with supply chain partners to reduce the impact that we have on the environment, and reduce our CO2emissions."
