At Chenwei Machinery, we know that a good trailer jack cannot be separated from solid raw materials. Taking our popular 8000-pound (8K) hand-cranked trailer jack as an example, the core structural parts are made of Q235B high-strength carbon steel. Its strength and toughness are better than ordinary steel, and it can better withstand heavy pressure, impact resistance, and is not easy to deform.
Q235B is a structural steel widely used in heavy industry. After our strict shearing, welding, heat treatment and surface anti-rust treatment, it has become the key to supporting the stability of the jack.
At Chenwei, we not only pursue the limit of bearing capacity, but also pay attention to the stability of each process. Every 8000-pound trailer jack must pass multiple rounds of functional testing and compression testing before leaving the factory to ensure the safety, durability and smooth operation of customers during use.
We are a local source factory in Hebei, focusing on the design and manufacturing of trailer jacks for more than ten years. Our products support OEM/ODM customization and are now exported to North America, Europe, Southeast Asia and other markets.
Behind a jack, there is not only the support of weight, but also the adherence to quality.
