Practical Guide For Manual Hydraulic Pallet Truck

In the daily operation of modern warehouses, manual hydraulic forklifts are widely used as a handling tool due to their simplicity, flexibility, and low cost. They are widely used in scenarios such as cargo handling, stacking, loading and unloading. Manual hydraulic forklifts have a simple and intuitive appearance, and are often seen as equipment that does not require professional skills. However, once operated incorrectly, it can cause serious accidents.

From the above accidents, it can be seen that the operational safety of manual hydraulic pallet trucks cannot be underestimated. Incorrect operating methods, inadequate assessment of the work environment, and illegal operations can all lead to accidents.

• Handle: It is a device used by operators to control the flow of hydraulic oil. By pushing or pulling the handle, the inlet and outlet of hydraulic oil are controlled, thereby adjusting the action of the hydraulic cylinder and achieving the lifting and lowering of the fork.
• Hydraulic cylinder: It is the power source of manual hydraulic pallet trucks, relying on the action of hydraulic oil to drive the piston to move up and down, thereby pushing the forks up and down.
• Frame: As the main structure of a manual hydraulic pallet truck, it is responsible for supporting and carrying the weight of the entire pallet truck as well as the loads generated during operation. The frame ensures that the pallet truck remains stable during handling and can withstand different weights of goods.
• Wheels: They are the moving part of a pallet truck, usually consisting of front and rear wheels. The front wheels are usually steering wheels, while the rear wheels are fixed wheels. Through a well-designed wheel system, pallet trucks can flexibly turn in various narrow working environments, ensuring stable driving.
• Fork: Used to support and transport goods, usually including adjustable fork arms. By adjusting the height and width of the fork arms, it can adapt to different sizes and weights of goods, ensuring safe and accurate handling.

• Hydraulic cylinder: Before pre operation, it is necessary to confirm whether there is any leakage in the hydraulic cylinder to ensure that the hydraulic system operates normally and there is no fluid leakage.
• Wheel: Before using the equipment, confirm that it rotates flexibly without any jamming or abnormal noise.
• Cleaning of foreign objects on wheels: Conduct a detailed inspection of the surroundings of the wheels and promptly remove any tangled foreign objects to prevent safety hazards caused by obstruction of operation.
• The principle of immediate discontinuation of non-conforming items: If any of the above inspections fail, the use of the equipment should be immediately stopped until the fault is resolved and confirmed to be safe and error free through further verification.

• Pressing: Place the control handle in the downward position, then lightly press the directional lever to activate the pallet truck pressing mechanism. During this process, it is essential to ensure that the weight of the goods carried does not exceed the maximum load limit specified by the pallet truck.
• Handling: After the goods are smoothly lifted off the ground, adjust the control handle to the middle position in a timely manner, and the pallet truck enters the dragging mode. During the transportation process, it is necessary to maintain a constant speed and avoid running or sudden acceleration.
• Unloading: After arriving at the designated location, the control handle needs to be moved up to the release position to gradually release the pressure of the pallet truck until the goods touch the ground smoothly. This step requires careful operation to prevent the goods from tilting or slipping.
• Empty driving: When the pallet truck returns empty or transfers to the next operating point, it is recommended to lift the front end of the pallet truck moderately to avoid direct friction between the front axle support frame and the ground, thereby extending the service life of the equipment and reducing unnecessary wear.

 Master effective pushing techniques

• Two handed operation: Operators should use both hands to operate the handle in order to better control lifting and driving, reduce fatigue on one hand, and improve overall stability and accuracy of the operation. Uniform pushing: When pushing the pallet truck, maintaining a stable pushing force and uniform speed can avoid sudden acceleration or deceleration, reduce the burden on the hydraulic system, and improve efficiency.
• Optimize the layout of the work area
• Goods stacking and path planning: Goods should be placed reasonably according to their frequency of use, with commonly used items close to the work site to reduce pallet truck travel distance. At the same time, plan the work channels reasonably to ensure that operators can quickly enter and exit the work area. Avoid narrow passages: Try to avoid stacking items in narrow passages to reduce time waste and risks when pallet trucks enter and exit.

 Improve the efficiency of load handling

Correct load placement: Goods should be placed as close as possible to the centerline of the pallet truck to ensure load balance. This not only improves handling efficiency, but also reduces the risk of pallet truck tilting. Prioritize handling goods of moderate weight: Operators should prioritize handling goods of moderate weight rather than overweight items. Moderate load can accelerate handling speed and reduce pressure on hydraulic systems and pallet truck structures.

 Reasonably choose the lifting height of the fork

Accurate adjustment of lifting height: When transporting goods, the lifting height of the fork should be kept within a suitable range as much as possible. Excessive lifting not only wastes time, but also increases the instability of the pallet truck's center of gravity. Generally speaking, the lifting height should be set below the cargo to avoid lifting it too high. Avoid empty lifting: It is not necessary to raise the fork too high when empty. Controlling the height of the fork to match the height of the cargo can improve driving stability and operational efficiency.

 Improve the efficiency of starting and stopping

Smooth start and stop: When starting and stopping, the operator should try to avoid sudden braking and acceleration. A smooth start and stop can reduce the vibration and impact of the pallet truck, extend its service life, and also reduce damage to the hydraulic system. Prepare parking location in advance: During the transportation process, operators should observe the parking location in advance, plan the parking path and space, and reduce repeated adjustments during the parking process.

• Hydraulic oil inspection: Regularly check the hydraulic oil level and quality, replace or supplement if necessary, to ensure system efficiency and reliability.
• Hydraulic pump and valve: Check the working status, no oil leakage or abnormal noise, regularly lubricate moving parts.

• Wheel maintenance: Regularly clean and inspect the wear of wheels, replace damaged wheels, and ensure safe and stable driving.
• Wheel axle lubrication: Regularly lubricate the wheels and support system bearings to reduce wear and improve operational efficiency.

2.Fork frame and fork arm

• Integrity check: Regularly check the integrity and safety of the fork frame and fork arm, repair or replace damaged parts.
• Identification of fork arm deformation: Regularly check the symmetry and straightness of the fork arm to avoid operational risks caused by deformation.

3.Handle and operating device

• Handle inspection: Ensure the flexibility of the handle, without any jamming or malfunction that may affect the accuracy of operation.
• Valves and operating levers: Check for smooth operation, regularly lubricate valves, and maintain efficient system operation.

1. Principle of single person operation: Manual hydraulic handling vehicles should be operated by only one person. When multiple people cooperate, a designated person in charge should be assigned to command and ensure coordinated operation.

2. Load limit: When loading, the handling vehicle must strictly comply with the load limit, and overloading, unbalanced loading, or single fork operation are prohibited. The weight of the goods should be within the carrying range of the transport vehicle, and the length of the fork should be sufficient to cover the pallet to ensure handling stability.

3. Avoid static overloading: It is forbidden to leave manual hydraulic transport vehicles idle for a long time after being overloaded, in order to avoid damage or safety hazards to the vehicle.

4. Prohibiting high-altitude throwing: It is strictly prohibited to directly throw goods from a high place onto the transport vehicle to avoid damage to the vehicle or goods.

5. Smooth Forking: The pallet truck fork must be fully inserted under the shelf, and only after the goods are smoothly lifted can they be pulled to ensure the safety and stability of the handling process.

6. Support for loose goods: When loading unstable or loosely packaged goods, personnel should be arranged to support them to prevent them from slipping or tipping during transportation.

7. Low level handling: When handling high objects and low loads, the forks should be placed as low as possible to reduce the risk of goods falling.

8. Avoid physical contact: During operation, it is strictly prohibited to place any part of the body near the mechanical lifting components of the transport vehicle, on the loaded goods, or under the forks to prevent accidents.

9. Control speed: When operating, the speed should be moderate and not exceed 3 kilometers per hour (the normal walking speed for adults is 5 kilometers per hour). When turning, it is especially necessary to slow down.

10. Avoid slope operation: It is strictly prohibited to operate the transport vehicle on inclined slopes or steep slopes. If it must be used on a slope, the operator should stand on the side of the transport vehicle to prevent inertia from causing loss of control and hitting people.

11. Prohibition of manned sliding: Manual hydraulic handling vehicles are strictly prohibited from carrying people or freely sliding on landslides to avoid serious accidents.

12. Clear line of sight: When the operator's line of sight is obstructed, it is strictly prohibited to carry out the operation to ensure safety.

13. Ground conditions: Do not use the transport vehicle on muddy or uneven ground. When using, pay attention to the passage and environment to avoid colliding with others, equipment, or other items.

14. Storage regulations: When the handling vehicle is not in use, the forks should be lowered to the lowest position empty and stored in a designated location to keep the vehicle clean and safe.

15. Regular maintenance: The personnel using the transport vehicle need to regularly maintain it, and department managers should arrange regular inspections or repairs to ensure good vehicle performance.

16. Damage handling: Damaged handling vehicles must be repaired or scrapped in a timely manner, and it is strictly prohibited to work with problems to ensure operational safety and production efficiency.
