The YD15-001~YD15-005 5-50Ton Air And Hydraulic Jack Series is a professional equipment designed to address the pain points of "difficult power adaptation in lifting scenarios, low safety in heavy-load operations, and inconvenient operation in limited spaces". With "dual-mode operation + graded load capacity + safe heavy-load handling" as the core, it fully covers lifting operations from 5Ton light-duty to 50Ton ultra-heavy-duty, solving the problems of traditional jacks such as "pneumatic jacks being unusable without air supply, manual jacks being laborious for heavy loads, and heavy-load jacks being bulky". It provides efficient and safe lifting solutions for multiple industries, with core advantages as follows:
Flexible switching between manual and pneumatic modes adapts to complex scenarios with or without air supply, balancing efficiency and practicality:
-
Pneumatic Mode: Efficient and Fast, Suitable for High-Frequency Operations
After connecting to 0.6-0.8MPa compressed air, the lifting speed is 5-8 times faster than pure manual jacks. For example, an auto repair shop uses YD15-002 (12Ton) to lift an SUV; in pneumatic mode, it only takes 30 seconds to lift from the minimum height to the working height (480mm), which is 5 times more efficient than manual operation (which takes 3 minutes). This is especially suitable for the "fast turnover" demand during peak maintenance periods; moreover, the pneumatic mode requires no manual pressing, reducing waist strain for maintenance personnel and lowering labor intensity.
-
Manual Mode: Emergency Reliable, Suitable for Scenarios Without Air Supply
When there is no air compressor, lifting can be achieved by pressurizing the manual hydraulic pump, making it suitable for scenarios such as outdoor rescue and field agricultural machinery maintenance. For example, an agricultural machinery station uses YD15-003 (20Ton) to repair a tractor in the field; without external power or air supply, pressing the manual hydraulic pump for 1 minute can lift the tractor to the maintenance height (490mm), no additional equipment is needed, and its emergency capability is far superior to pure pneumatic jacks.
Five models are divided according to load requirements, avoiding "wasting large equipment for small loads and taking risks with small equipment for large loads":
-
Light-Duty Models (YD15-001/002: 5-12Ton): First Choice for Family Cars and Light-Duty Vehicles
YD15-001 (5Ton) is suitable for lifting family cars (e.g., Toyota Corolla, Volkswagen Lavida). With a 6kg lightweight design (equivalent to the weight of a bag of rice), it can be carried to the trunk by one person, making it suitable for individual car owners to change tires in emergencies or auto repair shops to maintain light-duty vehicles; YD15-002 (12Ton) is upgraded to 12Ton capacity, capable of lifting SUVs (e.g., Haval H6) and light trucks (e.g., JMC Light Truck). With a weight of 12kg, it is still easy to move, and its applicable scenarios are expanded by 40% compared with the 5Ton model.
-
Medium-Duty Models (YD15-003/004: 20-32Ton): Core for Heavy-Duty Vehicles and Engineering Equipment
YD15-003 (20Ton) can lift heavy trucks (e.g., Foton Auman) and small engineering equipment (e.g., small loaders). With a weight of 17kg and reinforced handles, it can be carried to the operation point by two people; YD15-004 (32Ton) is designed for heavy engineering equipment (e.g., road rollers, excavators). Equipped with 8mm-thick base steel plate and 42MPa high-pressure resistant cylinder, there is no base sinking or cylinder expansion when lifting 32Ton equipment, and its stability is 30% higher than that of medium-duty models.
-
Heavy-Duty Model (YD15-005: 50Ton): Exclusive for Ultra-Heavy-Duty Equipment
The 50Ton super load capacity is suitable for lifting large engineering vehicles (e.g., muck trucks, large loaders) and heavy agricultural machinery (e.g., large combine harvesters). Equipped with 10mm-thick base steel plate and 50MPa high-pressure resistant cylinder, it can withstand long-term heavy loads (≥2 hours of continuous lifting) without deformation; although it has a net weight of 34kg, it is equipped with hidden universal wheels at the bottom (automatically locked when lifting), and only one person is needed to push it to the operation point. Compared with similar 50Ton jacks on the market (mostly over 50kg, requiring 3 people to carry), its mobility is increased by 60%.
Safety is enhanced from both structure and system to eliminate heavy-load risks:
-
Safety Overload Protection: Prevent Overload, No Risk-Taking
Built-in overload protection valve: When the load exceeds 10% of the rated capacity, it automatically cuts off the hydraulic/pneumatic circuit and stops lifting. For example, when using YD15-005 (50Ton) to lift 55Ton equipment, the protection valve is activated immediately to avoid cylinder explosion or equipment falling. Compared with traditional jacks without protection, the safety factor is doubled, completely solving the safety hazard of "overload use".
-
Rugged Structure: Stable Load-Bearing, No Deformation
Cylinders of high-load models are made of thick-walled seamless steel pipes. For example, the cylinder wall thickness of YD15-005 reaches 15mm, with high pressure resistance of 50MPa. The radial expansion of the cylinder is ≤0.2mm when lifting 50Ton equipment; the base is reinforced by welding with thickened cold-rolled steel plates, and the grounding area is 30% larger than that of ordinary jacks, with no risk of rollover during lifting. Even on slightly uneven ground (slope ≤3°), it can still bear loads stably.
Small size adapts to lifting scenarios with low chassis and narrow spaces:
-
Low-Height Adaptation: Can Lift Low-Chassis Vehicles
The minimum height is only 210mm (YD15-001), which can be easily extended under low-chassis vehicles such as family cars and sports cars, avoiding the trouble that traditional heavy-load jacks "cannot be inserted under the chassis due to too high minimum height". For example, when repairing a Porsche 911 (chassis height only 120mm), YD15-001 (minimum height 210mm) can be inserted with the help of thin gaskets to achieve stable lifting.
-
Small Volume for Flexibility: Usable in Narrow Gaps
The horizontal size is controlled within 300mm (e.g., YD15-004 has a width of only 280mm), which can be used in gaps between truck chassis beams and narrow support points of engineering equipment. For example, when repairing a truck gearbox, YD15-004 (32Ton) can be inserted from narrow gaps on both sides of the chassis to accurately lift the gearbox part, without disassembling surrounding components. Compared with bulky jacks, the operation efficiency is increased by 40%.
Scenario Requirement: Repair a Toyota Corolla (weight 1.8Ton), need to lift the vehicle to replace the oil filter; there is an air supply in the workshop, requiring high efficiency.
Operation Process:
- Select YD15-001 (5Ton): One person carries the 6kg jack to the bottom of the vehicle; the minimum height of 210mm can be easily inserted under the chassis.

- Maintenance personnel quickly replace the oil filter; after completion, lower the vehicle slowly through the pneumatic pressure relief valve, the whole process takes 15 minutes.
Result: Compared with traditional manual jacks, the maintenance time is reduced by 60%, and no manual pressing is required, greatly reducing the labor intensity of maintenance personnel.
Scenario Requirement: Replace the rear tire of a Foton Auman heavy truck (weight 28Ton); there is a heavy-duty air compressor in the logistics park, requiring stable lifting for heavy loads.
Operation Process:
- Select YD15-004 (32Ton): Push the 21kg jack to the bottom of the truck's rear wheel with the help of bottom rollers; the minimum height of 260mm is suitable for the truck chassis.
- Connect to a G3/8" air hose (large-flow air supply): Lift the truck to 400mm height in 1 minute in pneumatic mode; the safety overload system monitors the load (28Ton < 32Ton, stable load-bearing).
- Maintenance personnel disassemble and replace the tire, the whole process takes 30 minutes; no shaking or sinking occurs during lifting.
Result: It avoids the use of traditional mechanical jacks (which require the joint effort of multiple people); one person can complete the lifting, and the heavy-load stability is high, with no risk of vehicle tilting during tire replacement.
Scenario Requirement: Repair the chassis transmission components of a large Dongfanghong tractor (weight 15Ton); there is no air supply in the field, requiring manual lifting.
Operation Process:
- Select YD15-003 (20Ton): Two people carry the 17kg jack to the bottom of the tractor; the minimum height of 260mm is suitable for the tractor chassis.
- Switch to manual mode when there is no air supply: Maintenance personnel press the hydraulic pump to lift the tractor to 450mm height in 1 minute, meeting the chassis maintenance needs.
- During maintenance, the jack stably bears the 15Ton weight without sinking; the maintenance is completed in 2 hours.
Result: No temporary support frame is needed; the manual mode adapts to scenarios without air supply, solving the "difficult lifting" problem in field agricultural machinery maintenance, and is 50% more labor-saving than traditional manual jacks.
Scenario Requirement: Maintain a XCMG 50-type loader (weight 45Ton); need to lift the machine body to inspect the chassis hydraulic system; there is a high-pressure air compressor in the engineering station.
Operation Process:
- Select YD15-005 (50Ton): Push the 34kg jack to the bottom of the loader with the help of bottom rollers; the minimum height of 280mm is inserted under the chassis.
- Connect to a high-pressure air compressor (0.8MPa air pressure): Lift the loader to 420mm height in 2 minutes in pneumatic mode; the safety overload system ensures the load (45Ton < 50Ton) is safe.
- Maintenance personnel inspect the hydraulic pipelines and replace the filter element; the whole process takes 1.5 hours; the jack maintains stable load-bearing throughout, with no safety hazards.
Result: Compared with traditional large lifting equipment (which requires fixed installation and cannot be moved), it can be flexibly used in engineering sites, saving equipment transportation costs, and has high lifting efficiency, adapting to the "on-site maintenance" demand of engineering equipment.
A1: Air compressors should be selected according to the jack model: light-duty models (5-12Ton) can be adapted to ordinary small air compressors, while heavy-duty models (20-50Ton) require medium-heavy air compressors:
- 5-12Ton models (YD15-001/002): Pneumatic interface G1/4", requiring air compressor displacement ≥0.12m³/min. A 1.5kW household air compressor (displacement about 0.15m³/min) can be adapted; the lifting speed is slightly slow (about 1 minute), but it can be used normally.
- 20-50Ton models (YD15-003/004/005): Requiring air compressor displacement ≥0.3m³/min (20-32Ton) or ≥0.5m³/min (50Ton). Ordinary small air compressors have insufficient displacement, which will lead to slow lifting or inability to lift. It is recommended to match with medium-heavy air compressors above 3kW (e.g., 5.5kW air compressors commonly used in auto repair shops).
