A complete manual for manual hydraulic forklift operation and maintenance

1. The main components and functions of manual hydraulic forklifts Manual hydraulic forklifts are composed of a number of key components, each of which undertakes a specific function to jointly ensure its stable operation in various operating scenarios. The following are its main components and their functions: Handle: It is a device used by the operator to control the flow of hydraulic oil, by pushing or pulling the handle, controlling the inlet and outlet of hydraulic oil, so as to adjust the action of the hydraulic cylinder and realize the lifting of the fork. The handle is usually designed for easy handling,

ensuring that the operator can easily control the lifting and steering of the truck. Hydraulic cylinder: It is the power source of manual hydraulic forklifts, relying on the action of hydraulic oil to drive the piston to move up and down, and then promote the lifting of forks. The performance of hydraulic cylinders directly affects the lifting capacity and stability of forklifts, so their maintenance and upkeep are crucial. Frame: As the main structure of the manual hydraulic forklift, it is responsible for supporting and carrying the weight of the entire forklift and the load generated during operation. The frame ensures that the forklift remains stable during handling and can withstand loads of different weights. The frame is usually designed with high-strength steel to ensure its durability over long periods of use. Wheels: are the moving parts of the forklift, usually including the front and rear wheels. The front wheels are usually steered wheels, while the rear wheels are fixed. Through the well-designed wheel system, the forklift can be flexibly steered in a variety of narrow working environments to ensure stable driving. Equally important is the maintenance and upkeep of the wheels to prevent failures due to wear or entanglement of foreign objects. Forks: Used to support and carry goods, usually including adjustable wishbones, by adjusting the height and width of the wishbones, can adapt to different sizes and weights of goods, to ensure the safety and accuracy of handling. The adjustment function of the fork allows it to flexibly respond to different types of goods, improving work efficiency. 2. How to operate manual hydraulic forklifts safely and efficiently In order to ensure the safe and efficient operation of manual hydraulic forklifts, operators must follow a series of specifications and steps. The following are the safety checks and operation steps before operation: Safety inspection before use: Hydraulic cylinder: Before pre-operation, be sure to confirm whether there is leakage in the hydraulic cylinder to ensure that the hydraulic system is operating normally and there is no fluid leakage. Wheels: Before using the device, make sure that it rotates flexibly and that there is no jamming or abnormal sound. Wheel foreign body cleaning: Inspect the wheel in detail and remove the entangled foreign matter in time to prevent potential safety hazards caused by obstructing operation. The principle of immediate deactivation of nonconforming items: If any of the above inspections fail, the use of the equipment should be stopped immediately until the fault is eliminated and confirmed to be safe and correct after re-verification. Operation steps: Pressing: Put the control handle in the downward pressure position, and then gently press the directional control lever to start the forklift pressure mechanism. Pulling goods: After suppressing the goods from the ground, pull the control handle to the middle position, you can drag the goods, and you can not run when pulling the goods, you need to slow down. Decompression: After pulling the goods to the destination, hit the control handle to the upper position and decompress the forklift until the goods hit the ground. Empty operation: When the empty vehicle is running, the forklift should be properly pressed and lifted to avoid the front axle support frame from contact with the ground and wear.

3. Key points of daily maintenance and maintenance of manual hydraulic forklifts Daily maintenance and maintenance is the key to ensure the long-term stable operation of manual hydraulic forklifts. The following are the main maintenance points: Hydraulic system: Hydraulic oil inspection: Regularly check the hydraulic oil level and oil quality, and replace or replenish if necessary to ensure the efficiency and reliability of the system. Hydraulic pumps and valves: check the working status, no oil leakage or abnormal noise, and lubricate the moving parts regularly. Exhaust: Exhaust regularly to prevent air from entering the hydraulic pump and causing the cargo pressure not to rise. Wheel & Support System: Wheel Maintenance: Regularly clean and check the wear of the wheel, replace the damaged wheel, and ensure driving safety and stability. Wheel and axle lubrication: Regularly lubricate the wheel and support system bearings to reduce wear and improve operating efficiency. Forklift frame and wishbones: Integrity check: Regularly check the integrity and safety of forklift frames and wishbones, and repair or replace damaged parts. Wishbone deformation identification: Regularly check the symmetry and linearity of the wishbone to avoid operational risks caused by deformation. Handle & Operating Device: Handle Inspection: Ensure that the handle is flexible, and there is no jamming or malfunction, which affects the operation accuracy. Valves & Levers: Check the smoothness of the operation, lubricate the valves regularly, and keep the system running efficiently. 4. Safety precautions for the use of manual hydraulic forklifts In order to ensure the safe use of manual hydraulic forklifts, operators must strictly abide by the following safety precautions: Principle of single operation: manual hydraulic pallet trucks should be operated by only one person, and when multiple people collaborate, a person in charge should be designated to command in a unified manner to ensure that the operation is coordinated and consistent. Load limit: When loading, the truck must strictly abide by the load limit, and it is forbidden to overload, eccentric load or single fork operation. The weight of the goods must be within the carrying range of the truck, and the length of the forks must be sufficient to cover the pallet to ensure the stability of handling. Avoid static heavy load: It is forbidden to stand for a long time after the manual hydraulic pallet truck is heavily loaded, so as not to cause damage or safety hazards to the vehicle. It is forbidden to throw objects from high altitudes: It is strictly forbidden to throw goods directly from a high place onto the truck, so as not to cause damage to the vehicle or damage to the goods. Smooth fork picking: The fork of the truck must be completely inserted under the shelf, and the goods can be pulled and transported only after the goods are forked smoothly to ensure the safety and stability of the handling process. Avoid unstable goods: It is forbidden to load unstable or loosely packed goods, and personnel support should be arranged if necessary. Control the position of the fork: when handling high objects and low loads, put the forks in the lowest position as possible to avoid the goods from falling. Avoid body parts near mechanical lifting parts: It is forbidden to place any part of the body near mechanical lifting parts, on the loaded load, and under the forks. Avoid operating on inclined slopes: It is strictly forbidden to operate manual hydraulic pallet trucks on inclined slopes or steep slopes, if manual hydraulic pallet trucks are used on slopes, the operator shall not stand in front of manual hydraulic forklifts to avoid manual hydraulic pallet truck inertia resulting in too fast and out of control to hit people.

Clear line of sight: It is strictly forbidden to work when the line of sight is obstructed.
Avoid using on muddy or uneven ground: It is forbidden to use on muddy and uneven ground, pay attention to the passage and environment, and avoid bumping into other people, equipment and other items.
Regular maintenance: The user must maintain it regularly, and the department management personnel must arrange regular maintenance or repair.
Damaged vehicle disposal: Damaged manual hydraulic forklifts must be repaired or scrapped, and it is forbidden to work with illness.
