From Cast Steel to Ductile Iron: Shijiazhuang Glitter Technology's Fifth Wheel Manufacturer Targets 25,000kg Loads

Fleet managers running heavy trailers know one component failure can idle a rig for days: the fifth wheel coupling. Sourcing a robust, inspectable fifth wheel that resists stress fractures is often slow and uncertain. Shijiazhuang Glitter Technology Co…

Product Description

Across long-haul transport, the interface between tractor and trailer is a critical stress point. A fifth wheel that fails under load can cause downtime, cargo delays, and safety incidents. The shift from cast steel to ductile iron fifth wheels reflects a broader industry effort to reduce coupling failures and extend service intervals. Ductile iron offers higher tensile strength and ductility compared to traditional grey cast iron, making it better suited to dynamic loads.

Shijiazhuang Glitter Technology Co., Ltd responds with a heavy-duty 3.5-inch steel plate traction fifth wheel engineered from ductile iron, available in mounting heights of 150mm, 170mm, 185mm, and 200mm. The unit supports vertical loads of 20,000kg or 25,000kg depending on configuration, with net weights ranging from 122kg to 188kg across variants. Buyers can specify customisable colour and marking, and every unit undergoes 100% inspection before shipment. The fifth wheel is packed on pallets for transport, with standard package dimensions of 120×100×90 cm and a gross weight of approximately 1,000kg per pallet.

• Vertical load rating up to 25,000kg for heavy-duty trailer applications.
• Ductile iron construction for improved tensile strength and crack resistance.
• Four mounting height options to match different tractor/trailer combinations.
• 100% inspection and one-year guarantee reduce sourcing risk.

Company Profile

Shijiazhuang Glitter Technology Co., Ltd is a supplier of trailer components and related parts, with a catalog that includes suspension systems, axles, leaf springs, special vehicles, tank trailers, and used trucks.

Buyer Advantages

For sourcing directors, the decision often comes down to load rating and inspection rigor. This model offers a vertical load capacity of 20,000kg or 25,000kg depending on configuration, and the manufacturer states that each unit undergoes 100% inspection before shipment. The ductile iron construction is chosen for its tensile strength and resistance to cracking under cyclical loads, which is a critical factor in stop-and-go fleet operations.

The availability of multiple mounting heights (150mm, 170mm, 185mm, 200mm) allows buyers to match the fifth wheel to existing trailer fleets without extensive modification. Customizable colour and marking further support fleet branding and asset identification. At a published range of US$110–200 per unit, the model positions as a cost-effective heavy-duty option.

Service Highlights

Published service terms include a one-year guarantee and a 15-day delivery time from order. Buyers can customize the mark/logo on the unit, and the colour is customisable. Standard packaging uses pallets, with package dimensions of 120×100×90 cm and gross weight around 1,000kg per pallet. The supplier provides 100% inspection on all units prior to dispatch.
