The YD16-001/002/003 22-50Ton Pneumatic/Hydraulic Axle Jack Series is professional equipment designed to address the pain points of "difficult axle lifting for heavy-duty vehicles, cumbersome operation, and low positioning accuracy". With "heavy-load stability + convenient operation + precise positioning" as the core, the three-grade models cover the needs of medium-heavy to ultra-heavy vehicles, solving the problems of traditional axle jacks such as "insufficient load capacity leading to deformation, laborious movement, and difficult positioning". It provides efficient and safe heavy-duty vehicle repair solutions for logistics parks, auto repair shops, and engineering teams, with core advantages as follows:
Aiming at the characteristics of heavy axle weight and high lifting risk of heavy-duty vehicles, the load-bearing capacity is enhanced from material to structure:
-
High-Strength Wear-Resistant Materials, No Deformation Under Heavy Loads
Cylinders of high-load models are made of thick-walled seamless steel pipes. For example, the cylinder wall thickness of YD16-003 (50Ton) reaches 18mm, with high pressure resistance of 50MPa. The radial expansion of the cylinder is ≤0.3mm when lifting a 50Ton axle, which is 70% more stable than ordinary carbon steel cylinders (with expansion often reaching 1mm); the base is made of 12mm thickened cold-rolled steel plate, and the grounding area is 40% larger than that of traditional jacks. Even when lifting on slightly uneven ground (slope ≤3°), there is no risk of rollover, completely solving the problem of "swaying under heavy loads".
-
Dual-Drive Modes, Balancing Heavy-Load Efficiency & Emergency Needs
The pneumatic mode is compatible with heavy-duty air compressors, and the lifting speed is 6-8 times faster than pure manual jacks. For example, a logistics park uses YD16-002 (35Ton) to lift the axle of a heavy lorry; in pneumatic mode, it only takes 40 seconds to lift from the minimum height to the working height (547mm), which is 7 times more efficient than manual operation (which takes 5 minutes), meeting the "fast turnover" demand during peak maintenance periods; when there is no air supply, the manual hydraulic mode can be used for emergency lifting. For example, YD16-001 (22Ton) is used to manually lift a faulty lorry during outdoor rescue, no additional equipment is needed, and its emergency capability is far superior to pure pneumatic jacks.
Optimizations are made throughout the movement, positioning, and return processes to reduce the operation difficulty of heavy tools:
-
Tires + Long Handle, Ultra-Easy Movement & Positioning
Equipped with 2 large-size hard rubber tires, which are wear-resistant and have low pushing resistance. For example, YD16-003 (46kg) can be easily pushed to the lorry axle by one person on cement ground, 80% more labor-saving than jacks without wheels (which require 2 people to carry); the long T-handle is 600mm long, allowing precise adjustment of the jack position from the side of the vehicle, especially suitable for lorries with large overhangs (such as semi-trailers). There is no need to crawl under the vehicle for adjustment, avoiding collision risks, and the positioning efficiency is increased by 50%.
-
Self-Retracting Spring, No Manual Pulling for Return
The built-in self-retracting spring return system allows the ram to automatically retract when pressure is released after lifting. It can retract from the maximum height to the minimum height within 10 seconds (for 22Ton models) or 8 seconds (for 35/50Ton models), saving 80% of time compared with traditional jacks that require "manual pulling for return" (which takes 1 minute). It is especially suitable for high-frequency maintenance scenarios, reducing the repetitive labor of maintenance personnel.
Parameters are designed according to the axle height needs of heavy-duty vehicles, avoiding "unable to lift due to insufficient height or unable to insert due to excessive height":
-
Low-Height Adaptation, Capable of Lifting Vehicles with Low Axles
The minimum height of YD16-001 (22Ton) is only 225mm, which can be easily inserted under vehicles with low axles such as light trucks and medium lorries. For example, when lifting a JMC heavy light truck (with an under-axle gap of 230mm), it can be stably placed without heightening; the minimum height of 35/50Ton models is 277mm, suitable for medium-high axle vehicles such as semi-trailers and engineering vehicles, covering the under-axle gap needs of most heavy-duty vehicles.
-
Long Adjustable + Lifting Stroke, Sufficient Maintenance Height
The 35/50Ton models have an adjustable height of 120mm and a lifting height of 150mm, with a maximum height of 547mm, providing sufficient maintenance space after lifting. For example, when maintaining the axle of a semi-trailer, YD16-002 (35Ton) can provide an operating space of more than 500mm after lifting, allowing maintenance personnel to easily disassemble axle sleeves and replace bearings without hunching over, improving maintenance comfort and efficiency.
Scenario Requirement: Replace the rear axle tire of a semi-trailer (weight 30Ton); there is a heavy-duty air compressor in the logistics park, requiring fast lifting and sufficient operating space.
Operation Process:
- Select YD16-002 (35Ton): One person pushes the 42kg jack to the rear axle of the lorry; the 180mm rubber tires easily cross small obstacles on the ground.
- Connect to a 0.8MPa air compressor: Lift the axle to a height of 500mm (max height 547mm) in 40 seconds in pneumatic mode; use the long T-handle to precisely adjust the position, ensuring the jack is aligned with the axle support point.
- Maintenance personnel disassemble and replace the tire; after completion, release the pressure, and the jack automatically retracts within 8 seconds. The whole process takes 30 minutes.
Result: Compared with traditional mechanical jacks (requiring 2 people to carry and 5 minutes to lift), the efficiency is tripled, and there is no need to crawl under the vehicle for adjustment, making the operation safer.
Scenario Requirement: Inspect the front axle transmission components of a Foton medium lorry (weight 20Ton); there is no air supply in the workshop, requiring manual lifting and convenient return.
Operation Process:
- Select YD16-001 (22Ton): Push the 38kg jack to the axle with the help of tires; the minimum height of 225mm is compatible with the under-axle gap (230mm) of the lorry.
- Switch to manual mode when there is no air supply: Press the hydraulic pump to lift the axle to a height of 400mm in 1 minute, providing sufficient inspection space.
- After inspection, release the pressure, and the jack automatically retracts to the minimum height within 10 seconds, no manual pulling required. The whole process takes 1.5 hours.
Result: The manual mode adapts to scenarios without air supply, and the self-retracting function saves return time, improving efficiency compared with traditional manual jacks (which take 1 minute to return) with lower operation intensity.
Scenario Requirement: Replace the drive axle bushing of a loader (weight 45Ton); there is an air compressor on the engineering site, requiring stable lifting for heavy loads and rollover-resistant tires.
Operation Process:
- Select YD16-003 (50Ton): Push the 46kg jack to the drive axle; the thickened rubber tires are rollover-resistant, adapting to the gravel ground on the engineering site.
- Connect to the air compressor: Lift the drive axle to the maximum height of 547mm in 50 seconds in pneumatic mode; the 12mm thickened base stably bears the 45Ton weight.
- Maintenance personnel replace the bushing; after completion, release the pressure, and the jack automatically retracts within 8 seconds. The whole process takes 2 hours.
Result: The 50Ton heavy-load capacity is compatible with the loader weight, and the rollover-resistant tires adapt to outdoor scenarios, avoiding the problem of "easy tire damage" of traditional jacks, improving maintenance safety and efficiency.
Scenario Requirement: Maintain the middle axle bearing of a semi-trailer (weight 32Ton); precise jack positioning is required, and sufficient space is needed after lifting.
Operation Process:
- Select YD16-002 (35Ton): Use the long T-handle to adjust the position from the side of the truck, no need to crawl under the vehicle, and complete positioning in 30 seconds.
- Lift the axle to a height of 500mm in pneumatic mode; the 120mm adjustable height allows fine adjustment of the support position, ensuring sufficient operating space under the bearing.
- Maintenance personnel disassemble and replace the bearing; the whole process takes 1 hour, with no swaying during lifting and sufficient operating space.
Result: The long handle solves the positioning problem of semi-trailers with large overhangs, and the sufficient lifting height improves maintenance comfort, saving 40% of time compared with traditional jacks (which require repeated position adjustment).
A1: Lifting is not recommended as there are serious safety risks. The rated load of YD16-001 is 22Ton, and 30Ton exceeds the rated value by 36%, far exceeding the safety margin (usually 10% of the rated value). Forced use will cause cylinder bursting, base deformation, or even jack collapse, leading to axle falling and vehicle tilting accidents. To lift a 30Ton axle, YD16-002 (35Ton) or a higher-load model should be selected; over-specification use is strictly prohibited.
A2: It is not laborious for one person to push, and small gravel has little impact on movement, as the design is adapted to complex outdoor ground:
- Labor-saving pushing: The 46kg weight is distributed on 2 large-size rubber tires, resulting in low ground pressure. On cement or asphalt ground, an adult male can push it with one hand, 80% more labor-saving than jacks without wheels (which require 2 people to carry);
- Gravel adaptation: The rubber tires are hard and thickened with a diameter of 180mm, which can easily cross small gravels below 5mm without jamming or air leakage; if encountering larger gravels (≥10mm), they can be cleaned in advance or crossed with the help of a crowbar, without affecting overall movement efficiency.
A3: It is mostly caused by insufficient air compressor pressure, blocked air hoses, or pneumatic valve failure. Troubleshoot in the following steps:
- Check air compressor pressure: Ensure the air compressor output pressure is 0.6-0.8MPa. If the pressure is below 0.6MPa (e.g., small air compressors), it will cause slow lifting; a high-power air compressor (≥3kW) should be replaced;
- Clean air hoses and interfaces: Disconnect the G3/8" pneumatic interface, check if the air hose is bent or the interface is blocked by debris, replace the bent air hose or blow out interface debris with compressed air, then reconnect and tighten;
- Overhaul the pneumatic valve: If the above operations are ineffective, disassemble the pneumatic valve core, wipe off debris with alcohol and apply a small amount of grease, then reinstall and test. If it is still slow, contact the manufacturer to replace the pneumatic valve (priced at 50-80 yuan/piece).
A4: Rust-induced jamming of the spring can be solved by rust removal and lubrication, and anti-rust maintenance should be done daily:
- Rust removal and lubrication: First, release the pressure in the jack, disassemble the spring protection cover, gently polish the rust on the spring surface with sandpaper (400 grit), then apply lithium-based grease (e.g., No. 3 lithium grease), and press the ram repeatedly 3-5 times to ensure uniform distribution of the grease;
- Daily maintenance: After outdoor use, rinse the base and spring protection cover with clean water, wipe dry and spray anti-rust paint (e.g., epoxy anti-rust paint); when not in use for a long time, place the jack in a
