Best All Rounder
Lightweight Sack Truck
This model can handle a maximum of 100kgs of weight, but only weighs 7kg itself. More than enough for most jobs and still includes a fold away steel tow for easy storage. Another great feature is that is has a telescopic handle/back so that extended it manage heavy loads, but contracted it can be stored under a shelf easily. A good lightweight option.
Economy Sack Truck
Probably one of the cheapest around but certainly not the least quality. This model is well designed with solid wheels, made from steel and comes with proper handle grips. Finished in epoxy yellow paint (resistant to scratches). You can find this sack truck here.
