新加坡采购需求：履带滚轮、托链滚轮、链轮、惰轮、履带链条、履带组件

I'm looking for a heavy-duty anti-derailment track guard system suitable for forestry excavators, specifically designed for machines with tiltrotators. The system needs to provide full side containment with front and rear guides, reinforced side plates, and ideally bolt-on wear plates. It should be robust enough to handle forestry operations and side loads, and compatible with 600 mm steel shoes. Please provide a quote for a complete set (left + right), including all necessary bolts, material specifications, plate thickness, and overall weight. Also, include high-quality photos or drawings before production. Additionally, I need removable bolt-on rubber asphalt pads for road transport and suitable for farm applications. These pads should fit the 600 mm steel shoes and allow for easy replacement of any worn sections. Ensure the design can withstand Nordic climate conditions, with temperatures dropping as low as -25°C.
