Our Forged Ball and Pintle Combo Hitch is a multi-functional heavy-duty trailer towing component independently developed and manufactured by Qingdao Grand Forging. Combining a ball hitch and pintle hook into one integrated unit, this product becomes an all-in-one towing solution, widely applied for medium and heavy-duty trailers, agricultural trailers, construction transport vehicles, RVs and flatbed trailers. Buyers can switch between ball connection and pintle hook connection freely according to different trailer types, which greatly improves usage flexibility and saves the procurement cost of multiple separate towing accessories.
Different from low-cost cast products circulating in the market, our combo hitch adopts integral hot forging technology with high-quality carbon steel blanks. After high-temperature heating, precision die forging, trimming and shaping, the metal internal structure forms continuous and complete fiber flow lines. This production method effectively avoids common defects of casting products such as internal pores, sand holes and hidden cracks. Under heavy load, bumpy road conditions or sudden impact, forged towing parts maintain stable mechanical performance and greatly reduce the risk of sudden fracture, which is the core guarantee for driving safety. Every structural part of the hitch including the main body, connecting lugs and locking components are strictly processed to ensure overall structural strength.
The product undergoes precise CNC machining for all mounting holes and matching surfaces. The machining tolerance is controlled within a reasonable range, which ensures smooth assembly with standard receiver tubes. The matched trailer ball adopts polishing and chrome plating treatment, featuring smooth surface, low friction and flexible rotation during towing. Meanwhile, we are equipped with safety cotter pins as supporting accessories. After locking installation, the hook can effectively prevent accidental separation during transportation, eliminating potential safety hazards in long-distance travel.
For surface protection, the standard process is high-adhesion black anti-rust spray painting. The compact paint film can block the erosion of rainwater, mud, salt fog and corrosive substances. Whether used in dry inland areas or humid coastal regions, the forged hitch can resist oxidation and rust for a long time and reduce daily maintenance work. If customers have higher anti-corrosion requirements, we can provide hot-dip galvanizing surface treatment for customized orders.
We implement full-process quality control for all forged trailer hitches. Raw material composition inspection is carried out before production. Finished products will be sampled regularly for tensile load testing, impact testing and appearance inspection. All testing standards comply with common North American and Australian towing industry requirements. We maintain stable mass production capacity and can arrange production reasonably according to customers' order volume. The conventional production lead time is 30 days after order confirmation.
As a professional forging manufacturer with decades of experience, Grand Forging focuses on the research and production of trailer towing forged parts. Besides standard combo hitches, we provide flexible OEM and ODM customization services. Our technical team can develop new forged products according to customers' drawings, samples or special technical requirements, including adjusting overall dimensions, rated load, installation hole spacing and surface technology.
For packaging, we use shockproof inner packaging together with carton and pallet reinforcement to avoid paint scratch and deformation during long sea and land transportation. Our combo hitches have been exported to many overseas markets and won consistent recognition from trailer manufacturers, machinery dealers and transport operators. If you are looking for reliable, high-strength forged towing equipment, our ball and pintle combo hitch will be your ideal choice. We sincerely welcome global buyers to ask for samples, visit our factory and negotiate long-term bulk cooperation.
