Jiaxing Weiying Industry And Trade Co., Ltd. has been a professional hydraulic tool manufacturer since 2004, offering a broad range of lifting equipment to automotive workshops, garage owners, and fleet maintenance centers worldwide. The WY6490j Hydraulic Low Profile Floor Jack is one of our best-selling service trolley jacks, developed to deliver quick lifting speed with a stable wheeled base for daily auto repair tasks. Its low-profile saddle and streamlined chassis allow technicians to position the jack under modern vehicles with reduced clearance, while the quick-lift pump shortens the time required to raise the car. We build this jack with a focus on productivity, durability, and operator safety, making it a practical investment for professional auto service environments.
Main Features:
- Low-profile frame design – The jack body is constructed with a compact height to fit under sedans, coupes, and modified low suspension vehicles.
- Quick-lift hydraulic pump – A two-stage pumping mechanism raises the saddle rapidly to the vehicle contact point and then switches to a slower, power-assisted stroke for controlled lifting.
- Heavy-duty steel construction – The frame and chassis are fabricated from reinforced steel for long-term structural integrity.
- Swivel casters and rear wheels – Integrated wheels enable smooth rolling and easy positioning inside busy workshops.
- Built-in safety valve – The hydraulic system includes an overload protection valve to prevent excessive lifting beyond rated capacity.
- Rubber saddle pad – A non-slip rubber cushion on the lifting saddle helps protect the vehicle's pinch welds from scratches and slippage.
- Easy release control – The lowering valve handle allows precise and gradual descent of the lifted vehicle.

Efficiency for Busy Workshops:
Efficiency is the core advantage of the WY6490j in a working garage. Traditional bottle jacks require dozens of strokes to raise a vehicle to the working height, which consumes time and causes arm fatigue. The two-stage quick-lift pump of this floor jack brings the saddle to the chassis in just a few strokes, and the secondary pump then takes over to provide a powerful lift with minimal exertion. For busy auto service centers, this feature can noticeably increase the number of cars handled per day while reducing physical strain on technicians.
Low Profile Design for Modern Vehicles:
Ground clearance has become a major issue as car manufacturers introduce more aerodynamically styled sedans and electric vehicles with low chassis lines. The WY6490j was designed with a slim, low-profile housing that can slide underneath most passenger cars, including sports models with reduced clearance. The minimum chassis height, combined with a long reach, allows the operator to place the saddle precisely at the recommended lift point without awkward cranking or extra adapters.
Mobility and Handling:
The rolling trolley base transforms this floor jack into a mobile workshop assistant. Equipped with swivel front wheels and smooth-rolling rear wheels, the WY6490j can be moved easily from the front axle to the rear axle, or between different work bays. The rust-resistant finish and sealed wheels make the unit suitable for daily work on concrete or epoxy-coated floors, and the steering handle provides positive control when positioning the jack in confined spaces.
Safety and Durability:
Safety is a non-negotiable factor when lifting a vehicle, regardless of whether it is a compact passenger car or a heavy SUV. The WY6490j is fitted with an overload safety valve that responds to pressure extremes and a protective hydraulic cylinder design that shields internal seals from external contaminants. All welds are inspected during production, and every unit is test-cycled before leaving our factory. The high-strength steel frame is engineered to resist twisting even when the load is not perfectly centered, offering a stable lifting platform for a variety of chassis configurations.
Wide Vehicle Coverage:
The WY6490j is suitable for a wide range of vehicles, from compact city cars and sedans to SUVs and light vans with a gross weight within the rated capacity. It is commonly used for wheel and tire replacement, brake disc inspection, underbody maintenance, and quick oil change. The optional capacity versions allow the buyer to select the model that best matches their service needs, while the core frame structure and hydraulic pump remain the same for consistent operation.
Quality Control and Testing:
Quality control is carried out in multiple stages. After cutting and welding of the steel frame, each unit enters the surface treatment line to protect against moisture and minor impacts. The hydraulic cylinder is assembled in a clean environment and undergoes a leak test, and the assembled floor jack is cycled multiple times under load for function testing. Only units that pass the full inspection are packed for export, which keeps the after-sales failure rate very low for our importer partners.
OEM and Customization Options:
As an experienced manufacturing company, we realize that different markets have different preferences for color, handle design, and packaging. The WY6490j can be customized with your private label, brand color, and custom carton design. The minimum order quantity for customized versions is flexible, and samples are available before mass production. Please share your specification sheet or sample requirement with our sales team so we can adjust the production accordingly.
Maintenance and Operating Tips:
To guarantee a long service life, we recommend checking the hydraulic oil level every six months, keeping the moving parts clean, and avoiding impact loading on the saddle. The jack should be stored with the lifting arm fully lowered, and the release valve should be closed when not in use. These simple steps will maintain the pump response and prolong the life of the sealed hydraulic system.

Frequently Asked Questions:
Q1: What is the lifting capacity of the WY6490j?
The standard WY6490j can be configured with a lifting capacity of 1.5 tons, 2 tons, or 3 tons depending on the requirements of your market. Please contact our sales team to confirm the available options and choose the best capacity for your typical vehicles.
Q2: Can this low profile jack fit under a lowered sports car?
Yes. The low-profile body is one of the main design targets of this model. It is suitable for sports cars, coupes, and sedans with reduced ground clearance. We still recommend measuring the actual ground clearance of the target vehicles before placing a large order, since suspension modifications vary widely.
Q3: What hydraulic oil is recommended for maintenance?
We suggest using a high-quality hydraulic jack oil, such as ISO VG 32 grade, and keeping the oil level in the reservoir within the marked range. Regular oil checks every six months are sufficient for typical workshop use.
Q4: Can we have our own logo printed on the jack?
Yes. We support OEM and ODM services, including custom colors, private badge, and custom packaging. Send us your design file or reference sample, and our engineering team will confirm the artwork and production details.
Q5: Is the jack easy to move around the garage?
It has front swivel casters and rear wheels that allow smooth movement and rotation. The long handle gives the operator sufficient leverage to steer the jack into position and to pump the lifting arm.
Q6: What warranty or after-sales support do you provide?
For every exported unit, we provide after-sales technical support and can discuss warranty terms based on the order quantity and market. Defective parts reported within the agreed period will be replaced or repaired in the next shipment.
Q7: Do you accept small test orders?
Yes. We accept sample orders to let you test the WY6490j before bulk procurement. For customized versions, we also request a small initial order to confirm the production standard before larger quantities are scheduled.
