As part of Dingchi’s relative series, it works seamlessly with other models like the 4718Q (OE# 4711Q) and 4711Q (OE# A3222 K 2169), offering users flexible replacement options. The 4707Q stands out for its balanced blend of durability, compatibility, and performance: automated production lines guarantee consistency, while specialized treatments enhance its ability to withstand heavy-duty use.
The 4707Q’s brake lining carries WVA# 19030/33, a certification from the World Vehicle Association that validates its friction performance, heat resistance, and safety. This certification ensures the lining meets global standards, making the 4707Q suitable for international markets.
To ensure structural reliability, the 4707Q uses fixed-time welding penetration. This standardized process creates strong, uniform welds that resist cracking under stress, a key advantage for trailers and ROR equipment that experience frequent braking.
Dingchi’s automated production lines, equipped with precision sensors, monitor every step of the 4707Q’s manufacturing. From cutting raw materials to final assembly, this automation minimizes variability, ensuring that each brake shoe has the same dimension, strength, and performance.
Every 4707Q Brake Shoe undergoes heat treatment to strengthen its metal structure. This process improves the shoe’s resistance to high temperatures and wear, extending its service life and reducing the need for frequent maintenance.
Logistics trailers, which transport goods across long distances, require brake shoes that can handle constant use. The 4707Q’s durability and WVA-certified lining make it ideal for these trailers, providing consistent braking on highways and urban roads alike.
ROR equipment in ports and warehouses is used to move containers or heavy pallets, requiring brake components that can handle repetitive, short-distance braking. The 4707Q’s low wear rate and fast response time make it suitable for these environments, ensuring safe and efficient operations.
A: WVA# 19030/33 is a global certification that confirms the lining’s friction coefficient, heat resistance, and safety. It ensures the 4707Q’s lining performs consistently across different temperatures and conditions, a critical factor for reliable braking.
A: The 4707Q (16.5"*7") and 4711Q (16.5"*8.625") differ in width: the 4711Q is wider, making it suitable for larger trailers. The 4707Q, with its smaller width, is better for mid-sized trailers and ROR equipment. Both share similar quality features like heat treatment and welding penetration.
A: Yes, the 4707Q’s heat-treated metal and WVA-certified lining perform well in cold weather. The lining’s friction performance remains stable even at low temperatures, while the shoe’s metal structure resists corrosion from snow or ice.
A: Regularly inspect the 4707Q for lining wear (replace when thickness is below 3mm), weld integrity, and rust. Clean the shoe with a dry brush to remove dust or debris, and ensure the brake system is properly lubricated to prevent sticking. For heavy-duty use, schedule inspections every 2–3 months.
