Quality analysis of manual forklifts: There is a significant difference in the quality of manual forklifts in the current market. Some brands achieve durability and ease of operation through high-strength steel, sealed oil cylinders, and user-friendly design. However, we need to be vigilant about issues such as falsely labeling load-bearing capacity and material degradation in low-priced products. The following is a specific analysis:

1、 The core features of high-quality manual forklifts

High strength structure

Steel selection: High quality brands such as Nori and Hugong use Q345 low-alloy steel, which has a bending strength 40% higher than ordinary Q235 steel. The thickness of the fork and the diameter of the hydraulic cylinder are scientifically proportioned according to the load-bearing requirements to ensure long-term use without deformation under a load of 2-3 tons.

Welding process: Mechanical arm welding technology makes the interface smooth and beautiful, reduces stress concentration points, and improves overall structural stability. For example, the arc force manual forklift achieves seamless interface connection through welding robotic arms, significantly enhancing its load-bearing capacity.

Sealing and Durability

Oil cylinder design: The overall sealed oil cylinder (such as Shengdiao brand) adopts high-precision grinding tubes and imported oil seals to prevent oil leakage hazards, and the maintenance cycle is extended to more than 1 year.

Hydraulic system: Integrated hydraulic stations (such as Honglu equipment) achieve smooth lifting speed through integrated valve cores and internal relief valves, and have overload protection function to avoid overload damage.

Humanized operation

Handle design: Ergonomically wrapped rubber handles (such as those from Shanghai Industrial and Commercial Group) have excellent anti slip effects and reduce operational fatigue; The control lever integrates a mechanical locking mechanism (such as the Jungheinrich AMX I15 series), which can fix the fork position when not in use, improving safety.

Adjustment function: The width of the fork can be adjusted (340mm-990mm) to accommodate different pallet sizes; Some models (such as a certain brand in Taixing) achieve a weighing accuracy of ± 0.5% by optimizing the hydraulic layout, meeting the requirements of refined operations.

2、 Quality differences and selection risks

Low price product trap

Virtual weight bearing: In popular e-commerce products, some products priced below 2000 yuan have been tested and deformed under a load of 3 tons, while mainstream brands (such as Gaodebao) ensure load-bearing stability through reinforced and thickened design.

Material degradation: Low priced products may use Q235 steel or recycled materials, which have insufficient bending strength and are prone to problems such as fork bending and hydraulic system oil leakage during long-term use.

Differences in functional configuration

Wheel material: Polyurethane wheels have better wear resistance than nylon wheels, but the cost is twice as high; Special tires should be selected for the cold storage environment to reduce the increase in rolling resistance coefficient.

Additional features: Electronic scale heavy-duty manual forklifts (such as Rio Tinto and FAYA) are equipped with high-precision instruments and transformers, but the price is 30% -50% higher than ordinary models.

3、 Quality assurance and after-sales service

Testing Standard

High quality brands provide third-party testing reports, with a focus on verifying the GB/T 5184-2018 fork bending test data to ensure that the safety factor meets the standard.

For example, the Junhengli AMX I15 series has passed CE certification, and its special cavity structure design avoids residual pollutants, meeting high hygiene standards in industries such as pharmaceuticals and food processing.

After sales network

Brands with high localization service coverage, such as Hebei Liediao, can achieve a 48 hour response time and reduce equipment downtime.

Brands such as Nori and Hugong offer a one-year warranty period, and some models (such as the Gaodebu electric hydraulic model) support 300 lifting cycles on a single charge, reducing long-term usage costs.
