Whistl has launched the upgrade of its trailer fleet following a £3m investment.

The mail, parcels and fulfilment specialist will take delivery of 20 Don-Bur double deck trailers over the next 18 months, through an agreement with TIP Trailer Servies.

The design of the trailer has been developed for high volume pallet and cage transportation in a collaboration between Don Bur, TIP and Whistl.

The new trailers have been equipped with the Don-Bur Safety Suite to further enhance safe operation.

Features include EBS-Safe, an intelligent EBS monitoring system that actively checks ISO 7638 connections and issues alerts in the event of power or signal loss.

The trailers are also kitted with Suspension-Safe, which alerts the operator if the trailer’s air suspension is raised above ride height, reducing the risk of bridge strikes.

Other safety features include Leg-Safe which ensures landing legs are fully lowered when decoupling and Deck-Talk, a warning system that issues spoken status alerts to nearby personnel when the lifting deck is being operated.

In addition to these safety features, the new trailers also help cut fuel costs by reducing drag through an aerodynamic roof design.

They also sport roof-mounted solar panels which enable standalone lifting deck operations and robust light-weight composite side panels ,which boost internal capacity.

The trailers are also fitted with TIP telematics, integrated into Whistl’s transport management system, for real-time performance and location monitoring.

The new trailers also feature a bright, colourful and simplified Whistl brand livery.

Ian Keilty, Whistl chief executive, said: “We are delighted that by working in partnership with Don Bur and TIP we have developed a trailer that meets our operational, safety and environmental needs. It gives us greater efficiency whilst reducing our impact on the environment.”

Daniel Challinor, Don-Bur commercial director, added: “This trailer is the result of close collaboration between Don-Bur, TIP, and Whistl.

“It’s an excellent example of how advanced engineering can enhance both safety and efficiency for high-volume operations.”
