Improper operation or maintenance of manual hydraulic forklifts (ground oxen) during use can easily lead to equipment damage or even safety accidents. The following are three common vulnerable scenarios and analysis:

1、 Overloading operation: Double damage to hydraulic system and structure

Phenomenon:

The forklift nameplate indicates the rated load capacity (such as 3 tons), but the operator forcibly moves overweight goods to save time (such as using a 1-ton forklift to move 1.8 tons of goods).

consequence:

Hydraulic system collapse: The hydraulic cylinder's seals fail due to excessive pressure, resulting in oil leakage; Long term overloading may cause hydraulic pump cylinder explosion, completely losing its lifting ability.

Structural deformation: Forks may bend or weld seams may crack due to long-term excessive pressure, and the frame may twist due to uneven stress, resulting in equipment scrapping.

case

A warehouse worker used a 1-ton forklift to transport 1.8 tons of goods, but the hydraulic cylinder suddenly leaked oil, causing the fork to fall instantly and the goods to topple and damage the equipment. Fortunately, there were no casualties.

2、 Unbalanced load/single fork operation: stability imbalance causing rollover

Phenomenon:

The goods are not completely placed in the center of the fork, or only one side fork is used for handling, resulting in a shift in the center of gravity.

consequence:

Risk of rollover: When turning or bumping during operation, goods are prone to falling, injuring personnel or damaging equipment.

Component damage: One side force causes deformation of the fork, axle, or frame, accelerating wear.

case

The workers stacked the goods on a single-sided fork, and when pushing them, they turned and threw the goods, hitting nearby equipment and causing economic losses.

3、 Adverse environmental use: Accelerating component aging and failure

Phenomenon:

Using a forklift in muddy, waterlogged, salty air, or narrow passages without taking protective measures.

consequence:

Hydraulic system contamination: Ground impurities enter the hydraulic oil circuit, block valves or wear seals, causing lifting failure.

Wheel set jamming: The wheels are stained with mud or salt, which hinders rotation, makes pushing difficult, and may even get stuck.

Corrosion damage: The salty air in the seaside warehouse accelerates the rusting of metal parts, shortening the service life of equipment.

case

The seaside warehouse did not perform anti-corrosion treatment on the forklift, and after long-term use, the frame rusted severely, and the axle got stuck and could not be moved, requiring a complete replacement.

Suggestions for preventive measures

Strictly adhere to load standards:

Before handling, check the weight of the goods against the rated load of the forklift and prohibit overloading.

The center of gravity of the goods should be aligned with the center of the fork to avoid unbalanced loading or single fork operation.

Regular maintenance and inspection:

Check the hydraulic oil level, wheel assembly status, and fork deformation daily, and repair immediately if any problems are found.

Regularly lubricate friction parts such as axles and seals to reduce wear.

Optimize the homework environment:

Keep the ground flat and dry, and avoid working in muddy, waterlogged, or narrow spaces.

Use corrosion-resistant and explosion-proof forklifts in special environments such as chemical and coastal areas.

Strengthen operational training:

New employees need to undergo training before taking up their positions, familiarize themselves with equipment performance and safety regulations.

Regular retraining to strengthen safety awareness and prevent unauthorized operations.
