When evaluating the quality of manual forklifts, it is necessary to focus on the four core dimensions of hydraulic system reliability, frame structure strength, operational safety, and maintenance convenience, and make comprehensive judgments based on common fault cases. The following is a specific analysis:

1、 Hydraulic system: Sealing and stability are key

The hydraulic system is the core power source of manual forklifts, and its quality directly affects operational efficiency and safety. Common issues include:

Oil leakage: The joint surface of the oil cylinder barrel, piston rod seal, hydraulic pump interface and other parts are prone to oil leakage due to aging seals, improper installation or oil pollution. Oil leakage not only wastes hydraulic oil and increases maintenance costs, but also leads to insufficient pressure, causing the fork to lift slowly or even fail to work.

Abnormal lifting of forks: If the forks cannot reach the highest, do not rise or fall, it may be caused by insufficient hydraulic oil, impurities in the oil, air entering or improper adjustment of the pressure relief valve.

Evaluation suggestion:

Check the sealing material of the hydraulic system (using high-performance polyurethane or fluororubber sealing rings can improve wear resistance).

Observe the cleanliness of hydraulic oil and regularly replace it with hydraulic oil that meets the standards.

Test the lifting speed and stability of the fork to ensure no jamming or leakage.

2、 Frame structure: Strength and durability determine service life

The frame is the load-bearing body of a manual forklift, and its quality directly affects stability and service life. Common issues include:

Frame deformation: Long term overloading or use of inferior steel may cause the frame to bend or break, increasing the risk of tipping.

Wheel wear: Inert rotation of wheels or damaged bearings can increase operational resistance and reduce efficiency.

Evaluation suggestion:

Check the frame material (such as high-strength steel) and welding process to ensure there are no cracks or virtual welds.

Test the smoothness of wheel rotation and check if the bearings need lubrication or replacement.

Confirm the rated load capacity to avoid overloading during use.

3、 Operational safety: detailed design ensures human-machine safety

Safety is of utmost importance in the design of manual forklifts, and attention should be paid to the following details:

Overload protection: Lack of overload protection device may cause damage to the frame or hydraulic system, and even lead to tipping accidents.

Anti slip design: Insufficient anti slip treatment on the surface of the fork may cause the goods to slip, posing a threat to the safety of operators.

Operational field of view: Frame or fork obstructing the line of sight may increase the risk of collision.

Evaluation suggestion:

Confirm if overload protection devices (such as pressure relief valves) are equipped.

Check if the anti slip patterns on the surface of the fork are clear, and add anti slip pads if necessary.

Simulate operational scenarios and evaluate the openness of the field of view.

4、 Maintaining convenience: reducing long-term usage costs

The convenience of maintenance directly affects the full lifecycle cost of forklifts. Common issues include:

Difficulty in component replacement: Non standardized design may result in time-consuming and laborious replacement of seals, oil cylinders, and other components.

Complex fault diagnosis: Lack of modular design or fault code prompts may prolong downtime.

Evaluation suggestion:

Prioritize forklifts with modular design for quick replacement of faulty components.

Confirm whether the manufacturer provides detailed maintenance manuals and spare parts support.

Test the fault diagnosis process (such as detecting hydraulic system leaks through pressure gauges).
