These transport devices have no lifting function. Transport trolleys should be stable, easily manoeuvrable and easy to load, and should have a sufficient loading area.
Sack trucks for the transport of chairs, barrels, plates or rolls usually have two wheels. Ergonomic advantages are, for example, an electric stair climbing function and adjustable steering handles. Roller bases are placed under the load and are used, for example, to transport barrels, plates or ladders.
