I. Product Specifications (SPECIFICATION)

II. Product Details (PRODUCT DETAILS)

1. Integrally Forged Q235 Low-Carbon Steel Pump Body, Extra Load-Bearing & Anti-Deformation:The pump body is manufactured via integral forging of Q235 low-carbon steel, with a tensile strength of 375-500MPa. According to third-party pressure tests, the pump body deformation is ≤0.3mm under 12-ton rated load, and there is no risk of cracking or leakage even under short-term 15-ton overload pressure; the surface undergoes phosphating rust removal + high-temperature electrostatic painting, with a coating thickness of 80μm, passing the 72-hour salt spray test without rust. Its service life can reach more than 10 years in humid engineering sites and oily maintenance environments, far more durable than ordinary segmented pump bodies.
2. 12-Ton High-Pressure Hydraulic Output, Strong Power Without Loss:Built-in high-pressure sealed hydraulic cylinder with a working pressure of up to 31.5MPa, and hydraulic oil transmission efficiency of over 95%, which can quickly drive extra-heavy hydraulic tools (such as 12-ton hydraulic jacks) to complete equipment lifting — it only takes 2 minutes to lift an 8-ton medium excavator, with efficiency 40% higher than ordinary hydraulic pumps of the same specification; the hydraulic pipeline interface follows the international general G3/8 thread standard, adapting to quick connectors of most extra-heavy hydraulic tools, and can be connected and used without modification, avoiding power loss caused by incompatible interfaces.
3. Ergonomic Labor-Saving Design, Effortless Operation:Equipped with a 20cm extended ergonomic operating handle, the end of the handle is wrapped with a 3cm thick anti-slip rubber sleeve. The force application point fits the palm's force trajectory when pressing, and the operating force can be reduced to 12-15kg (equivalent to lifting a 15L bucket of water) by leveraging the lever principle. Compared with ordinary short-handle hydraulic pumps, the operating force is reduced by 30%, and female users or people with limited strength can also independently drive 12-ton equipment; the handle can be rotated 180° to adjust, adapting to different operating angles and avoiding wrist soreness during operation.
4. Dual Safety Protection, Secure & Anti-Fall:The hydraulic system is equipped with dual safety devices — ① Overload pressure relief valve: When the pressure exceeds the 15-ton safety threshold, it automatically relieves pressure to protect the pump body and equipment, avoiding structural damage caused by overload; ② Mechanical locking valve: After the equipment is lifted to the target height, manually close the locking valve to fix the position. Even if the hydraulic system fails suddenly, it can prevent the equipment from falling rapidly. The locking load-bearing capacity reaches 18 tons, far exceeding the rated load, completely eliminating the concern of "fear of out-of-control lifting of extra-heavy equipment".

III. Application Scenarios (APPLICATION SCENARIOS)

1. Emergency Repair of Extra-Heavy Equipment at Engineering Sites:When extra-heavy equipment failures (such as track replacement and chassis component maintenance) occur in construction and mining engineering sites for medium excavators and loaders, this hydraulic pump can be carried to the site, and the equipment can be lifted to the maintenance height with the help of a 12-ton hydraulic jack; the 14KG lightweight design is convenient for transportation by engineering vehicles, and the compact 68X19X15CM package can be easily placed in the trunk, without relying on fixed power sources, adapting to the extra-heavy engineering scenario of "emergency repair and mobile operation" and solving the problem of no high-pressure power on site.
2. Truck/Bus Maintenance in Heavy-Duty Repair Plants:When heavy-duty truck and bus repair plants conduct chassis overhauls (such as gearbox replacement and suspension system maintenance), this hydraulic pump can drive heavy-duty lifts to stably lift 10-12 ton vehicles to a height of 2.5-3 meters; high-pressure power ensures no jamming during lifting, and dual safety protection prevents vehicle falling, adapting to the repair plant's needs of "precision maintenance of extra-heavy vehicles" and improving maintenance efficiency and safety.
3. Extra-Heavy Cargo Handling at Ports/Warehouses:When ports and large warehouses handle extra-heavy cargo within 12 tons (such as large metal components and heavy container accessories), using this hydraulic pump with hydraulic stacking equipment can realize vertical lifting and loading/unloading of cargo; manual operation does not require external power supply, adapting to open-air operation areas without power interfaces at ports. The anti-slip base has a friction coefficient of ≥0.9 with the ground, and the pump body is stable without displacement during operation, ensuring safe and efficient loading/unloading of extra-heavy cargo.
4. Large Agricultural Machinery Maintenance at Agricultural Machinery Repair Stations:In agricultural production, when agricultural machinery repair stations maintain large agricultural machinery (weight 5-12 tons) such as large tractors and combine harvesters, this hydraulic pump can drive hydraulic lifts to lift the agricultural machinery to a suitable height, facilitating chassis maintenance and tire replacement; the 12-ton load capacity covers the weight of most large agricultural machinery, and the labor-saving operation design adapts to the single-person operation scenario of agricultural machinery stations, solving the pain point of "no professional power equipment for large agricultural machinery maintenance".
