Revolutionizing the handling of goods, self-leveling trucks and trolleys feature an innovative spring-loaded platform mechanism that effortlessly adjusts its height in response to the applied weight—lowering during loading and elevating upon unloading. This intelligent design eliminates the need for operators to reach down to the depths of the trolley for the last items, significantly enhancing ergonomic efficiency, safety, and speed in loading and unloading applications. This transformative technology not only streamlines operations but also ensures a more ergonomic and secure handling of items.

“It is safe to say that, if you need a spring-lift or self levelling trolley, then you are in the right place!”

Used in the Hotel and Health industries for Linen and Laundry, also Warehouse picking. With the new manufactured to order range, we now supply the widest range of SLT's in Europe. For budgeting, the plastic models work out the least expensive and the aluminium systems the most expensive.

Manufactured in the UK Spring Lift Trolleys

CLM125 With Handle

As well as the spring lift trolleys above we have the following range that is manufactured to order offering a wider range of sizes and colours though with an extended lead time.


  • Self-levelling units are ideally located in situations that require a worker to be bending and lifting in their workplace.
  • By using a self levelling unit, the possibilities of a worker injuring their back are greatly reduced.
  • The panto-graph works by a scissors and spring system that is set at a pre-calculated rate/weight.
  • Each time an object is placed on the table-top, it lowers a little, leaving the item at a reachable height.
  • The reverse happens when removing objects from the unit, each time an object is removed the table-top rises, ensuring the items are always at the top of the unit to ease back problems in the workplace.
  • Self-levelling units can be placed in most straight sided containers.
  • Please find below a list of our most popular sizes.
  • If the size you require isn’t listed, please ask, we may have a unit suitable or alternatively, we can fabricate the item to your exact requirements.
  • Standard delivery is 6 to 8 weeks, as all these units are manufactured to order.

How the SLT (Self Levelling Trolley) Works

The plastic moulded trolley is specially engineered to have parallel sides, allowing the top to slid up and down without leaving gaps for linen or fingers. The SLT is so well engineered that it has to have a hole cut into the base so that the air can leave and enter when in use.

The Pantograph system shown, allows the top to lower even if all the weight is positioned on one side, and the spring is specially wound to offer a set resistance. Please let Merlin know what capacity you need when ordering. Some customers can have a system for dry or wet clothes in different colours for easy visibility.

For calculating the resistance you need to know the maximum weight of the items going in as this will be the resistance at which the self-levelling top sits at the lowest part of the trolley.
