Technical features
Stainless bolts are applied to the rubber seal fixing bolts in consideration of future maintenance, and hot-dip galvanization is applied to the fixing plates to prevent damage to the rubber seals due to corrosion.
The lower frame adopts a-beam and roof-type anchor system, ensuring excellent durability by stably transmitting the impact load of the wheel to the structure even for products with large expansion and contraction.
Double bolts are applied to extensions of 400mm or more to double the safety factor to maximize durability and secure additional safety.
