  • Features
    • QM Range: Cereals
      QM Range: Cereals – Our QM and QM00 range are both ideal for this type of work. The QM00 range has a marginally larger carrying capacity than the QM range with basic sides.
    • QM Range: Silage
      QM Range: Silage – Both our ranges of monocoque trailers are available with silage sides. The QM range is available with swinging tailgate style sides or silage attachment style sides; the swinging tailgate style sides allow for more capacity, while the silage attachment style sides are quicker to switch between silage and cereal set-ups. Our QM00 range is only available with silage attachment style sides. In 2014 we introduced our new silage attachment style sides that provide increased strength and rigidity thanks to the specially designed internal plate. The improvements do not stop there as the visual appearance of the sides have been modernized.
    • QM Range: Rootcrop
      QM Range: Rootcrop – Our QM range has 4' high sides to minimize the distance crops have to fall during loading. When specified with 560/60x22.5 wheels and a full width front window, our QM range is ideal for rootcrop work.
    • QM Body Design
      QM Body Design – The floors of the entire range are 5mm thick and the sides are either 3.5mm or 4mm thick, ensuring an extended service life. Every model also benefits from a fully-welded construction with a substantial number of floor and side bearers to improve overall rigidity and strength. The sides of the trailer are also welded on one of our robotic welders to provide an incredible level of finish that cannot be matched by hand-welding.
    • QM Chassis Design
      QM Chassis Design – The QM/11 model upwards uses a unique chassis design that is formed from heavy-duty channels with 8mm or 10mm reinforcing plates stitch welded to the channels. This set-up provides unrivaled strength, while also allowing the chassis to flex when required; if the chassis is too rigid then it can become prone to cracking and premature failure. Almost the entire chassis is now welded on a robot, ensuring perfect welds every time and adding to the overall chassis durability. The chassis design on the QM/16 and QM/1800 models are also further reinforced by an internal lattice work of steel plates, providing a tidy finish combined with the necessary strength.
    • QM Tipping Mechanism
      QM Tipping Mechanism – The tipping points of our QM/6 and QM/8 models use a toughened 24mm bolt and on our QM/11 model upwards, a fully bushed 50mm solid steel bar is used to eliminate any potential weak link in the design. Similarly our QM/11 model upwards also benefit from using a single chrome tipping ram, which had a faster cycle time than traditional twin ram designs increasing efficiency.
    • QM Spring Suspension Option
      QM Spring Suspension Option – Available on all our tandem axle QM models as a no-cost option and available on our QM/6 single axle model as a priced option. Our QM/8, QM/11, QM/12 and QM/1200 models us multi-leaf springs to keep the trailer height down for improved stability, while still providing excellent road performance. On our QM/14 model upwards 4-leaf parabolic springs are utilized to handle the increased weights.
    • QM Axles & Braking
      QM Axles & Braking – Every model in the QM range has hydraulic brakes as standard with the option for air brakes with load sensing and ABS. There is also the option for hydraulic load sensing. Our QM/11, QM/12 & QM/1200 models use 8 stud 350 x 90 axles, with the option to upgrade to commercial axles for high-speed road work. Commercial 10 stud 420 x 180 axles are standard on our QM/14 model upwards; these are the same size of axles that are used on HGVs and provide exceptional braking and high-speed performance.
    • QM Lighting Arrangement
      QM Lighting Arrangement – Lights are standard on all models in the QM range, but there are also various lighting options including; LED lights, high-level LEDs, LED beacons and dual lights. All lights are recessed into the back-rail of the trailer or are fully guarded.
    • QM Inspection Ladder
      QM Inspection Ladder – The whole QM range comes with an inspection ladder as standard, which is fabricated from chequered plate and precision welded by our robot welders before being treated with a galvanized finish.
    • QM Hydraulic Door Design
      QM Hydraulic Door Design – The QM range hydraulic door arms are formed from pressed steel plates to create a sleek and strong design. In addition the arms are now 150mm longer to provide increased clearance when discharging the load, this is particularly useful when tipping silage or maize. The hydraulic door option is standard on the QM/12 model upwards and optional on our other models.
    • QM Drawbar Design
      QM Drawbar Design – This intelligent design has resulted in our new drawbars being incredibly strong, while also creating a modern, sleek looking finish. This is only possible due to the advanced fabrication equipment we use; two 8mm plates are folded together by our CNC presses and overlapped before our robotic welders complete the process by welding the parts together.
    • QM Dealer Fit Ready
      QM Dealer Fit Ready – The simple idea of this new design approach and concept is to allow 80% of our optional extras to be retrofitted to our product ranges without the need for any fabrication or paint rectification. The QM range is naturally designed around this idea and the benefits are huge! It allows us as manufacturers to stock basic trailers that can be adapted to meet customer demands for improved delivery, it allows dealers to supply the correct specification of trailer to customers faster and for the farmer to add to the trailers' functionality and extend its lifespan. The best example of this is the ability to add air brakes to the QM range, so if a tractor is upgraded to air brakes the trailer can be made to match without the need to change the entire trailer!
    • QM Robotic Welding
      QM Robotic Welding – The introduction of robotic welders to our production line gives the Marshall QM range a unique and unrivalled level of finish and consistency. The chassis, drawbar, ram anchors and sides are all welded robotically; taking the quality far beyond what a man can achieve. This production and design method will continue to be integrated into our ranges throughout the coming years.
    • Paint Finish
      Paint Finish – Since November 2011 we have shot-blasted, this is acknowledged in the paint industry as the best possible method for preparing steel for painting. The shot-blasting creates a profile for the paint to adhere to, improving adhesion and in turn the protection offered to the steel. Our five man team of trained sprayers then use the latest spraying equipment to finish our products with a dual layer paint finish. Every machine is finished with 80 microns of high-build primer and 50 microns of gloss polyurethane; this combination provides excellent protection and a high-quality finish.
    • Delivery
      Delivery – Marshall Trailers uses a computerized build system to plan production to ensure that machines are delivered on time. The final stage of delivery is undertake by our two artic lorries, a 7.5ton rigid lorry and a number of other haulage partners.
    • Spare Parts
      Spare Parts – Marshall Trailers has a full selection of spare parts for all our ranges, most of which can be dispatched immediately. In some cases we have spares for machines dating back forty years, which gives of mind when you buy a Marshall that you will be properly supported well into the future.
  • Overview

    Features at a Glance

    The Marshall QM/6 is the entry level monocoque trailer in our range, but still has the same build and level of engineering that goes into all our trailers. The construction of the body is extremely robust, with 3.5mm sides and a 5mm flat floor ensuring the trailer can handle demanding work. The flat floor also prevents premature rusting of the trailer, since there are no joints for water to sit in. Furthermore the generous number of bearers and spacers means the trailer body is exceptionally strong and rigid, helping to prevent twisting or cracking after years of heavy use. Another beneficial standard feature is a tapered body allowing loads to be safely discharged without the risk of them sticking in the trailer.

    The chassis of the trailer uses our tried and tested design, developed over 60 years of producing agricultural trailers. It is over-engineered for the weight it is expected to carry, which is the most effective method of ensuring the trailer has a long-life. The tipping points for the body are 25mm in diameter, providing outstanding durability and again reducing the possibility of damage to the trailer when tipping.

    The engineering in a Marshall QM/6 combined with its compact design means it can properly and effectively handle the tasks of a larger trailer, while also being able to operate in a small area.

      What are the current regulations on agricultural trailer brakes?

      The law currently states that trailers travelling below 25mph have to have a braking efficiency of at least 25% (UK Road Vehicle Construction & Use Regulations). Above this speed it is unclear exactly what requirements an agricultural trailer has to meet, whether it is commercial braking requirements or still simply a 25% braking efficiency.

      There is currently EU legislation under discussion which would implement a 50% braking efficiency for agricultural trailers, but this has been already been debated for a number of years without it becoming law. It seems unlikely that it will be implemented within the next few years, if ever, since this would impose higher braking standards than required on commercial vehicles.

      Marshall products are fitted with hydraulic brakes as standard and on average provide a braking efficiency of 35%, which exceeds the current legal requirements. This impressive baseline performance is achieved by fitting high quality axles supplied by the world’s leading axle manufacturer, combined with enlarged 25mm brake cylinders and durable 2 wire hoses.

      Take time to examine the specifications of our models and take note of the brake sizes and axles sizes. In particular notice we fit commercial 420 x 180 10 stud axles as standard on our QM/14, QM/16, QM/1600 and QM1800 models; not 10 stud industrial axles, which provide significantly reduced performance. The way to tell the difference between these axles is a commercial axle uses an S-cam brake rode while an industrial axle uses a flat-cam brake rod.

      If a customer requires enhanced braking performance we also offer air brakes with loading sensing, full ABS systems and a number of axle upgrades. This guarantees a Marshall trailer can meet current legal requirements now and any EU legislation that could potentially be introduced in the future.
