Jo,
The guys in our Equipment Library use a trolley supplied by Slingsby. It is rated for 350Kg and does the job for us. The size is approx 5ft by 3ft by 3 ft deep. It carries pressure mattresses and all our infusion devices back and forwards on a daily basis. They have used it for several years now without any hitches. It has drop sides, handles front and back and is also very manoeuvrable.

The guys in main stores also use them to carry supplies to the Wards. Slingsby's number is 01274 721591.
