LOAD CAPACITY: 400-650 daNROLLER TREAD: TR-ROLL polyurethane tread; hardness 75 Shore A; excellent rolling resistance and elasticity; highly resistant to wear and to tearingCENTRE: weldless steel 
Designed for industrial environments, even in presence of alcohols, glycols, hydrocarbons. Not recommended in areas with organic acids and mineral acids, base solutions and saturated vapour.
Suitable for all types of floors, even outdoors. They facilitate the overcoming of obstacles.They do not damage or mark floors.
For each load and diameter, the table indicates the force (in daN) needed to push or tow a single wheel at the constant speed of 4 km/h on smooth flooring. For manual handling of a 4-wheeled trolley we recommend diameters that have values < 5 daN, for frequent handling we recommend diameters with values < 3 daN.
