The design virtually eliminates dirt and dust from the rolling surface. This reduces wear on the wheels of the trolley and end trucks. The smooth running surface reduces rolling resistance. The low profile of the steel track allows the system to be installed where headroom is a problem. The low track weight reduces the applied forces exerted on the supporting structure.
Long spans allow systems to be installed where hanging points are infrequent.
The 2 taper of the running flange helps to center the trolley in the track for smooth, effortless movement of trolleys and end trucks.
