Design & Handling
With its hand truck design, the Simpson CM61455-S provides excellent maneuverability. The durable steel frame of the assembly ensures its longevity, providing stability and shielding internal components from damage, even in tough conditions. The handle adds to the CM61455-S convenience of transport.
This unit, weighing 50 lbs, strikes a comfortable balance between portability and stability, ensuring easy maneuvering for users of various strengths. A significant portion of this weight is attributed to the inclusion of the 170cc engine and a sturdy steel frame. Despite this, the CM61455-S's two 12" never-flat wheels ensure effortless maneuverability.
