What is the function of supporting feet?
The support legs are height-adjustable, providing solid support when the Equipment is parked, and effectively increasing the overall load capacity.
Made of highly wear-resistant Nylon, the wider wheel is a Series with a medium load and a small wheel. It is suitable for commercial machinery equipment with high load and less movement. Among them, the large base plate is equipped with supporting feet, which can increase the load. The supporting feet can adjust the height and park the trolley stably at will.
1109 Series American Wheel Series is made of highly wear-resistant Nylon. The wheel width is larger and it is the Series with higher load capacity among small wheels. Suitable for commercial machinery equipment with high load and less movement.
If the Equipment is a commercial machine with a high load but low movement frequency, the large base support leg design of the 1109 American WheelSeries can provide stable parking and high load capacity; if you need a higher rigidity and low center of gravity design, you can refer to the 1109-HD American Machinery WheelSeries.

The support legs are height-adjustable, providing solid support when the Equipment is parked, and effectively increasing the overall load capacity.
Suitable for applications such as commercial machinery Equipment and computer server material racks with high load and less movement.
1109 Series is the standard model; 1109-HD Series uses higher rigidity plates and heat-treated beads, suitable for more demanding commercial machinery and AGV applications.
It is a model with a higher load in the small WheelSeries. It is recommended to consult with the actual Specification for confirmation.
