The YD19-007 3Ton Lightweight Hydraulic Floor Jack is a core piece of equipment designed to address the pain points of "heavy and hard-to-carry tools in heavy-load scenarios, poor lifting adaptation for low-chassis heavy vehicles, and low efficiency of light operations". With "lightweight heavy-load + low-chassis adaptation + efficient labor-saving" as the core, it solves the problems of traditional 3Ton jacks such as "excessive weight, inability to fit under low-chassis vehicles, and laborious operation". It provides a "portable, usable, and labor-saving" lifting solution for individual car owners (heavy SUV users) and small stores (light truck maintenance), with core advantages as follows:
Breaking the limitation of "heavy-load jacks must be heavy" of traditional 3Ton jacks, through "9mm ultra-thin cold-rolled steel + hollow frame design", it maintains a 3Ton load capacity while controlling the weight at 25.3kg (equivalent to 5 bags of 5kg flour). Adult males can carry it to the bottom of heavy SUVs with both hands, and female users can also move it for short distances with the help of a carrying strap (provided by the manufacturer); the 30.5×15.15×7.08-inch packaging size can be easily placed in the trunk of heavy SUVs such as Great Wall Cannon and Ford Everest (regular trunk volume ≥1000L), without occupying core storage space, making it "ready to use" for outdoor off-road emergencies.
The 95mm minimum height can be directly extended under low-chassis heavy SUVs (e.g., Toyota Prado with a chassis height of 130mm, Ford Everest with 120mm) and light trucks (Wuling Rongguang Mini Truck with a chassis height of 140mm) without adding thin steel plates or adjusting the vehicle position, avoiding "chassis guard deformation due to forced insertion". Compared with ordinary 3Ton jacks (mostly with a minimum height of over 120mm), the adaptation rate for heavy low-chassis vehicles is increased by 75%, so individual car owners (during off-roading) and stores (during maintenance) do not have to worry about "unusable tools".
The dual-cylinder parallel hydraulic system optimizes the oil circuit layout, with hydraulic oil flow 60% higher than that of single-cylinder design, and an operating force of only 60N. Only 32-35 pumps are needed to lift from 95mm to 487mm, 29% more labor-saving than ordinary 3Ton jacks (requiring more than 45 pumps); the 9mm cold-rolled steel main body has a permanent frame deformation ≤0.15mm after 80,000 fatigue tests (simulating repeated lifting of 3Ton load), and the verticality deviation is ≤0.3mm when lifting—80% more stable than jacks with plastic bases. Even when lifting a single tire of a heavy SUV unilaterally, there is no risk of vehicle tilting.
The saddle has a diameter of 110mm and honeycomb anti-slip patterns, with a friction coefficient ≥0.8 when in contact with the vehicle chassis. The horizontal anti-slip force is increased by 50% when lifting a 3Ton load, avoiding "local chassis depression due to point contact"; the quiet rollers are made of polyurethane-rubber composite material, with noise ≤55 decibels (equivalent to the volume of daily conversation) when pushed, which does not interfere with other operations in the garage or workshop. Moreover, the rubber rear wheels do not scratch the epoxy floor, making it more worry-free for store use.
The 487mm maximum lifting height is 16% higher than that of ordinary 3Ton jacks (mostly below 420mm), providing over 40cm of operating space after lifting—enough for maintenance personnel to disassemble the gearbox of light trucks (thickness about 25cm) and inspect the suspension system of heavy SUVs (needing 30cm gap). Compared with "long-stroke but heavy" professional jacks, the 487mm stroke controls the product weight while meeting heavy-load operation needs, better fitting the "lightweight first" demand of individual users and stores.
The hydraulic system adopts a fully protective design of "double seal rings + dust cover": the cylinder interface is equipped with a nitrile rubber main seal + PTFE auxiliary seal to prevent hydraulic oil leakage; the dust cover is closed when idle to prevent dust intrusion—even when used in dusty off-road sites or humid car washes, there is no need for frequent disassembly and cleaning. The rollers and saddle are made of wear-resistant materials; tests show that after 500 consecutive lifting operations, the component wear is ≤0.03mm, and the maintenance cost is 70% lower than that of ordinary jacks.
Scenario Requirement: A Great Wall Cannon Off-Road Edition (weight 2.3Ton, chassis height 130mm) has a flat tire during suburban off-roading; emergency tire replacement is required by one person, and the tool needs to be lightweight, able to fit under the low chassis, and compatible with heavy loads.
Operation Process:
- Take YD19-007 from the trunk, carry the 25.3kg tool to the bottom of the vehicle with both hands, and directly extend the 95mm minimum height under the chassis to align with the frame support point.
- Hold the handle and press to lift; after 35 pumps, the saddle rises to 450mm, lifting the tire 8cm off the ground (meeting the tire replacement requirement), and the anti-slip saddle ensures vehicle stability.
- Complete the tire replacement in 12 minutes, open the pressure relief valve to slowly lower the vehicle, and put the jack back into the trunk—no chassis scratches or operation jamming throughout the process.
Result: Compared with traditional 3Ton jacks (requiring two people to carry and unable to fit under low chassis), the tire replacement efficiency is increased by 50%, allowing individual car owners to complete off-road emergencies independently without relying on teammates.
Scenario Requirement: Maintain the chassis oil pipe of a Wuling Rongguang Mini Truck (weight 1.8Ton, chassis height 140mm); only one technician is working in the shop, and the tool requires convenient movement and high efficiency.
Operation Process:
- The technician pushes YD19-007 to the bottom of the truck alone; the 95mm minimum height easily extends under the chassis without adjusting the vehicle position.
- Press the handle to lift the vehicle to 400mm; the 487mm stroke provides sufficient maintenance space to disassemble and replace the oil pipe.
- During maintenance, the quiet rollers allow the jack to move flexibly around the vehicle without noise interference, and the whole process takes 40 minutes; after completion, push the tool to the next vehicle for continuous operation.
Result: Compared with 3Ton jacks without rollers (requiring two people to carry), the single-person maintenance efficiency is increased by 60%, and 3 more vehicles can be served per day, adapting to the "one-person multi-position" operation mode of small stores.
Scenario Requirement: Install a 2.8Ton generator (chassis height 150mm), requiring lifting to 350mm to place shock pads; the outdoor dusty environment requires dust resistance and stable heavy-load performance.
Operation Process:
- Two people cooperate to push YD19-007 to the bottom of the generator; the 95mm minimum height extends into the equipment base to avoid "base jamming the chassis".
- Press the handle to lift the generator to 350mm; the dual-cylinder hydraulic system ensures stable lifting, and the 3Ton load capacity stably supports the 2.8Ton equipment.
- Installation personnel place shock pads and fix anchor bolts; the whole process takes 1.5 hours, with no jamming or displacement of the jack.
Result: The sealed hydraulic design adapts to the outdoor dusty environment; compared with ordinary jacks (prone to failure due to dust), the installation process is uninterrupted, and the lightweight design avoids fatigue caused by frequent carrying.
Scenario Requirement: Replace snow tires for a Ford Everest (weight 2.5Ton, chassis height 120mm) at -15℃; the tool needs to start at low temperature and be labor-saving.
Operation Process:
- Take YD19-007 from the garage, push it to the bottom of the SUV's rear wheel; the 95mm minimum height is compatible with the chassis without heightening.
- The hydraulic system works normally in the low-temperature environment (the hydraulic oil uses a -25℃ anti-freeze formula); 32 pumps lift the vehicle until the tire is 7cm off the ground.
- Complete the tire replacement in 15 minutes, release pressure to slowly lower the vehicle, and push the jack to the tool storage area.
Result: It has strong low-temperature adaptability, and the labor-saving structure reduces operating intensity. Compared with ordinary jacks (prone to jamming at low temperature and laborious to operate), the winter tire replacement efficiency is increased by 40%, avoiding maintenance delays caused by tool problems.
A1: The overload protection will be triggered, and lifting is not recommended due to safety and equipment damage risks. The overload protection threshold of YD19-007 is 3.3Ton. Although 3.2Ton does not exceed the threshold, it is close to the safety upper limit: during lifting, the protection system may frequently trigger "oil cut-off and recovery" fluctuations, leading to unstable saddle lifting/lowering; moreover, under a 3.2Ton load, the frame and hydraulic system are in a high-load state for a long time, which will accelerate seal aging (service life reduced from 5 years to 2 years) and frame fatigue deformation, increasing maintenance costs. A jack with a rated load of 4Ton or above should be selected for lifting 3.2Ton light trucks.
A2: It is mostly caused by clogged pressure relief valve, stuck seals, or aging hydraulic oil, and can be troubleshooted in the following steps:
- Clean the pressure relief valve: Turn off the jack, disassemble the pressure relief valve (located under the handle), rinse the valve core impurities with alcohol, dry it, and reassemble to avoid oil circuit blockage caused by impurity jamming;
- Activate seals: If pressure relief is still slow, press the handle repeatedly 5-8 times (without lifting the vehicle) to move the seals and relieve sticking—usually, the pressure relief speed will be significantly improved after this operation;
- Replace hydraulic oil: If the jack has been idle for more than 6 months, the hydraulic oil may oxidize and thicken. Open the oil filling port to drain the old oil, add 46# anti-wear hydraulic oil (for northern winter, -25℃ anti-freeze type is recommended) to the scale line, and the normal pressure relief speed can be restored.
A3: Adult females can carry it easily through leveraging tools + correct posture. The specific tips are as follows:
- Use the carrying strap: Thread the wide carrying strap (provided by the manufacturer) through the handles on both sides of the jack, hold the two ends of the strap with both hands, and stand up using shoulder and leg strength to reduce arm force—this method saves 40% of physical effort;
- Ground sliding assistance: If the distance from the trunk to the bottom of the vehicle is ≤3 meters, lay the jack flat with the bottom touching the ground, push it gently to the side of the vehicle, then pick it up—saving 50% of effort compared to lifting it the entire time;
- Trunk support leverage: Place the jack on the edge of the trunk, hold both sides and slowly slide it to the ground, then push it to the bottom of the vehicle—avoiding excessive arm force when lifting it directly from the trunk.
A4: Worn anti-slip patterns will affect safety and need to be handled or replaced in time. The reasons and solutions are as follows:
- Safety Risks: After pattern wear, the friction coefficient between the saddle and the chassis decreases from 0.8 to 0.3, making it easy to slide under a 3Ton load, which may cause vehicle tilting;
- Temporary Handling: If no spare parts are available temporarily, paste a 3mm thick anti-slip rubber pad on the saddle surface (fixed with high-strength glue) to temporarily increase the friction coefficient—emergency use should not exceed 10 times;
- Long-Term Solution: Contact the manufacturer to purchase a saddle of the same specification (priced at 50-80 yuan/p
