Chenwei 8000 lbs Hand Crank Trailer Jack: Why do we choose Q235B steel?
In the trailer jack industry, material selection is a key factor affecting product quality. As a Hebei source factory with more than ten years of manufacturing experience, Chenwei Machinery always insists on using high-strength Q235B carbon structural steel for the main structure production of our 8000 lbs (8K) hand crank trailer jack.
✅ What is Q235B? Why is it more suitable for trailer jacks?
Q235B is a carbon structural steel with good plasticity, welding performance and tensile strength. It is widely used in load-bearing structures such as bridges, construction machinery and automobile chassis.
Compared with ordinary iron materials, Q235B has stronger mechanical properties and has:
Higher yield strength (≥235MPa)
Stronger impact resistance and deformation resistance
Stable chemical composition, welding is not easy to crack
This makes it very suitable for making heavy-duty hand crank trailer jacks, which can withstand large working loads and repeated operations without deformation.
✅ Advantages of Chenwei 8K trailer jack
The 8000-pound (8K) hand-crank jack we produce is widely used in trailers, RVs, agricultural machinery and other fields, with the following characteristics:
✅ Using Q235B raw materials, the structure is more stable
✅ Efficient gear transmission system, hand-cranking is more labor-saving
✅ A variety of heights/installation methods are available, supporting OEM customization
✅ Each unit undergoes strict load-bearing tests before leaving the factory
