[Product Information] Chenwei Machinery's High-strength Hand-cranked Trailer Jack Creates Professional-grade Lifting Support

Among the key components of trailer equipment, the quality of the jack directly determines the safety and convenience of vehicle lifting. Chenwei Machinery has launched a variety of hand-cranked trailer jacks, including round tube type, square tube type, black spray-coated and silver galvanized versions. The single unit has a load capacity of up to 12,000 pounds and is suitable for all types of heavy-duty trailer vehicles.

Comprehensively strengthen manufacturing details and polish every key part:

1. Screw system - the "heart" of strong support

The customized high-carbon steel screw (45 steel) has excellent compressive resistance and long life performance, which is the core guarantee for supporting 12,000 pounds of heavy load.

2. Precision structural pipes - sturdy and durable "skeleton"

Both round and square tubes are processed with high-precision technology and high-quality steel. The structure is stable and does not deform, ensuring long-term performance during high-intensity use.

⚙️ 3. High-performance components – smooth operation, strong and wear-resistant

All gears and nuts are die-cast using powder metallurgy technology and are subjected to high-temperature heat treatment to improve product strength and wear resistance, avoid problems such as "slipping" and "stuck" during operation, and ensure long-term stable use.

4. Automated welding – stable and consistent process guarantee

All key welding parts of the whole machine use fully automated welding equipment to ensure firm welding, neat appearance, and stronger tensile strength.

5. Appearance treatment – both beautiful and protective

Two appearance treatment methods are provided:

Galvanized silver: corrosion-resistant, suitable for rainy/coastal environments;

Black spray: anti-oxidation, scratch-resistant, strong texture.

6. Customized packaging service – flexible to meet different market needs

Support packaging design and proofing according to customer brand needs to enhance product added value and market recognition.

Chenwei Machinery has always adhered to the business philosophy of "quality first, customer first" and continued to invest in technology upgrades and product innovation. We not only provide standardized products, but also welcome OEM/ODM customized cooperation to tailor trailer jack solutions for customers in different usage scenarios.
