• Household trailer equipment

The durable rubber wheel allows smooth movement across different surfaces, making them practical for everyday use.

Strict Production Process and Quality Control

Trailer jacks are critical safety components, and Chenwei Machinery places great emphasis on quality control throughout the entire production process.

1. Raw Material Inspection

All trailer jacks are manufactured using high-strength steel materials sourced from reliable suppliers. Each batch undergoes inspections such as:

• Hardness testing

• Dimensional inspection

• Anti-corrosion evaluation

This ensures that every product starts with a strong and reliable foundation.

2. Precision Machining

Components are processed using CNC machines, stamping equipment, and cutting machines to ensure high accuracy.

The screw rod and gear system, which form the core of the trailer jack lifting mechanism, are produced using precision thread rolling technology, ensuring smooth and stable lifting performance.

3. Welding and Assembly

The load capacity of a trailer jack heavily depends on welding quality. Chenwei uses CO₂ shielded welding and automated welding equipment to ensure strong, uniform weld seams.

After welding, every joint is inspected carefully before proceeding to final assembly.

4. Surface Treatment

To improve durability and corrosion resistance, Chenwei offers several surface finishing options:

• Hot-dip galvanizing

• Electro-galvanizing

• Powder coating

Hot-dip galvanizing is particularly popular for marine and coastal environments, providing excellent resistance against rust and salt corrosion.

5. Functional and Load Testing

Before leaving the factory, every trailer jack undergoes multiple tests including:

• Manual operation testing

• Load capacity testing

• Stability evaluation

Some models are also subjected to fatigue testing to simulate long-term use conditions.

6. Final Inspection and Packaging

Our quality inspection team conducts final checks on:

• Appearance

• Dimensions

• Load capacity

• Surface finish quality

Qualified products are then packed using five-layer export cartons and pallet packaging to ensure safe transportation. Customized packaging such as color boxes, labels, and branded logos is also available.

OEM & Custom Trailer Jack Solutions

Chenwei Machinery also specializes in OEM and ODM trailer jack manufacturing.

We offer customization options including:

• Square tube or round tube structures

• Load capacities from 1000 lbs to 12000 lbs

• Different handle types (side wind, top wind, detachable handle)

• Adjustable lifting height

• Various surface finishes

For OEM customers, our engineering team can assist with product design, sample development, and mold production, ensuring a smooth transition from concept to mass production.
