RAEDER-VOGEL: Special wheel materials for cold store applications
Thursday, 18 May 2006
The tread material VULKOLLAN® fulfils almost all the requirements of modern industrial trucks regarding wear resistance and damping. However, this material reaches its limits in deep-freeze applications down to –35° C.

Especially on heavy-duty narrow-aisle trucks and reach trucks, flat spots develop overnight on the load and drive wheels. Due to the low ambient temperatures, these flat spots are slow to recover and can thus cause intolerable vibration. To avoid this we recommend the use of wheel treads with a higher shore hardness (95° instead of the commonly used 93° Shore A) which are more resistant to flattening and are consequently quick to recover their shape in the morning.
Traction problems in the deep freeze area – especially on the drive wheels of shuttle systems and tiller-steered trucks – can be overcome by using VULKOSOFT® or TRACTOSOFT® treads with the lower shore hardness 85° Shore A.

In mixed operations, i.e. for trucks that travel from the deep-freeze area to the loading zone or onto the ramp for truck loading, additional traction problems are caused by humidity. Our TRACTOTHAN® treads - compounded in a patented process using a granulate with lower shore hardness - offer the acceptable solution.
For very tough applications, e. g. in the fish industry, VULKOLLAN®-QUARTZ, where silica sand is embedded in the base material, is the best, but very abrasive, alternative.
