Five Major Dangerous Operations Warning for Manual Hydraulic Forklifts

Core Regulations for Safe Operation of Manual Hydraulic Forklifts: Guidelines to Avoid Five Major Dangerous Behaviors In the industrial handling sector, the safe operation of manual hydraulic forklifts is crucial. To ensure operational safety, it is essential to strictly adhere to the 'Five Prohibitions' principles and eliminate the following dangerous behaviors to prevent safety accidents.

1. Strictly Prohibit Overloading Every manual hydraulic forklift has its load limit; this 'limit' is a key indicator for ensuring the forklift operates safely and stably. Generally, the rated load information will be clearly marked in a prominent position on the forklift chassis, which is an important reference for safe operation. Overloading can cause significant damage to the forklift, potentially leading to hydraulic system overload, fork deformation, or even breakage. Therefore, before transporting goods, it is crucial to carefully check the weight of the goods and avoid the dangerous mindset of ‘just carrying one more box’ that can lead to fatal safety risks. Analyzing the Source of Danger The rated load of manual hydraulic forklifts is determined by various factors, including the performance of hydraulic cylinders and the thickness of fork steel. Once overloaded, a series of serious consequences can ensue: Hydraulic Oil Hose Bursting: When pressure increases sharply, the hose joint may not withstand high pressure, spraying high-temperature hydraulic oil, which can damage the equipment and potentially injure operators through burns. Permanent Deformation of Forks: Overloading can cause the forks to bend in ways that are not visually noticeable; this deformation can reduce the load-bearing capacity during subsequent uses, increasing operational risks. Axle Breakage: Under heavy loads, the steering axle bears tremendous pressure and is prone to breaking, leading to sudden loss of control of the forklift and causing unpredictable accidents. Key Points for Safe Operation Accurately Calculate Weight: When calculating the gross weight of goods, multiply the weight of individual items by their quantity, and do not overlook the weight of the pallet to ensure accurate data. Strictly Follow Labels: Carefully review the 'Rated Load' indicated on the forklift nameplate; for instance, if marked as 2000kg, that is the maximum load value for the forklift. To ensure safety, it is recommended to reserve a 10% safety margin to avoid operating at full capacity. Reasonably Select Equipment: For overweight goods, it is necessary to switch to a forklift with a higher carrying capacity; never forcefully use equipment that does not meet requirements for handling.

2. Eliminate Uneven Single-Fork Operations When using manual hydraulic forklifts to transport goods, maintaining balance is an important prerequisite for safety. Goods must be evenly placed on both forks, and unilateral load-bearing is strictly prohibited. Uneven loading on a single fork can easily lead to forklift tipping over or serious accidents such as goods falling. During operation, ensure that the goods are centered, and use straps to secure the load if necessary to prevent accidents due to shifting center of gravity.

Real Warning CaseOnce, a warehouse worker illegally used single-fork operation to pry a stuck pallet. During the operation, the fork suddenly side-slipped, and the forklift handle rebounded, striking the operator's liver, resulting in severe injury. This case profoundly warns us that single-fork offloading operations pose enormous safety risks.Danger Principle ExplanationWhen the single fork bears weight, the structure of the forklift creates a 'lever effect', leading to a series of dangers:Lateral Overturning: A shift in the center of gravity breaks the balance of the forklift, causing it to tip over, resulting in the cargo falling onto the operator, causing serious injuries.Fork Twisting: A single-sided fork bearing all the weight will experience immense pressure, potentially leading to a break from the base and causing cargo to drop.Handle Loss of Control: When unbalanced, the hydraulic system's pressure distribution becomes uneven, leading to the handle suddenly rebounding, which can cause the operator to lose control of the forklift and trigger an accident.Correct Operating RegulationsDouble Fork Center Placement: The width of the cargo should cover at least 2/3 of both forks to ensure that the cargo is evenly distributed over the two forks, maintaining the balance of the forklift.Symmetrical Stacking and Fixation: For loose cargo, wrapping film should be used to secure it, preventing the center of gravity from shifting during transportation due to movement.Prohibit Prying Operations: When encountering a stuck pallet, professional tools like pry bars should be used for assistance, and forks should never be used for hard prying to avoid danger.
