As a professional trolley jack manufacturer from Jiaxing Weiying Industry And Trade Co., Ltd., we understand that a car lift should be strong, stable, and gentle to the vehicle body. Our trolley jack for car is engineered with a curved saddle design that matches the typical profile of a car chassis, greatly reducing the risk of scratches and point pressure during routine lifting. Since 2004, our factory has focused on practical lifting equipment for workshops, garages, and mobile service teams, combining durable hydraulic components with a thoughtful contact surface.
The curved saddle is the standout feature of this trolley jack. Instead of a sharp or flat contact point, the saddle profile follows the rounded lower edge of a car floor panel. This spreads the vehicle weight more evenly and avoids concentrated stress that can bend the chassis edge or damage the underbody coating. It also gives the operator a naturally guided contact position, so the jack can be placed faster under the designated lift point. For cars with side skirts, plastic body cladding, or protective films, this design greatly improves service confidence.
Key features
- Curved saddle: matches the factory chassis contour and reduces point contact.
- Scratch protection: smooth, broad contact area lowers the chance of paint scratches on the lifting point.
- Optional rubber pad: an extra soft layer can be fitted for premium finishes and ceramic-coated vehicles.
- Hydraulic lifting unit: smooth pump action and controlled pressure release for precise work.
- Rigid steel frame: welded construction helps maintain stability during lifting and lowering.
- Compact floor-jack layout: easy to roll under a car and convenient for workshops with limited space.
- OEM friendly: frame color, saddle width, logo, and manual can be adjusted for distribution brands.
Technical construction and operation
Our trolley jack is built around a sealed hydraulic cylinder and a steel lifting arm. The handle is designed to give the operator a good mechanical advantage, so pumping is not overly tiring even when used many times during a busy workday. A release valve allows the load to be lowered in a controlled manner, which is especially important when working under vehicles or fitting exhaust components. The moving parts and pivot points are finished to resist normal wear, and grease fittings are placed in accessible positions for easy maintenance.
The base frame is wide enough to provide stable support but still has a low profile for sliding under a vehicle with limited clearance. The front caster and rear wheels are selected to keep the unit maneuverable on smooth workshop floors. When the jack is not in use, the compact shape allows it to stand in a corner or lie flat in a service van. This makes the curved saddle trolley jack a practical piece of equipment for both fixed garage operators and roadside assistance teams.
Why the curved saddle matters for your customers
Scratches on the chassis are usually caused by sharp saddle edges, hard rubber blocks, or incorrect lifting points. Our curved saddle is designed to avoid the most common source of these complaints: concentrated pressure on a small contact area. By spreading the load along the curved profile, the jack helps protect the paint layer, the anti-corrosion coating, and the original structural shape of the floor panel. In service marketing, this is a tangible benefit that a garage can communicate to car owners before and after the job.
Application range
This trolley jack is designed for passenger cars, sedans, hatchbacks, compact SUVs, and similar light vehicles. It is a good choice for general maintenance, tire change, brake service, oil change, and suspension inspection. The curved saddle construction also makes it useful in detailing centers and showrooms, where floor jacks are used to display or work on high-value vehicles without leaving marks.
For heavy trucks, buses, and industrial equipment, a standard car trolley jack is not suitable. We can suggest higher-capacity alternatives or specially engineered lifting solutions based on the actual vehicle weight and the height of the lifting points. Our sales team will ask for the target vehicle list before recommending the most appropriate model.
Maintenance and daily care
To keep the curved saddle trolley jack working well, we recommend simple daily care. Wipe the saddle and piston rod with a clean cloth, especially after working on cars with mud or road salt. Check the hydraulic oil level according to the user manual, and bleed the system if the pump feels soft. Lubricate the joints and caster wheels with a light machine oil. These steps help the jack remain stable and reduce unnecessary wear.

Customization and private label
As a manufacturer, we can adjust the curved saddle geometry to better match different car platforms sold in your market. If the standard jack cannot reach a particular lifting point, we can review the height and width requirements and provide a modified arm or saddle. We also accept frame color changes, printed body options, custom decals, and bilingual instruction manuals. These customization services are useful for importers that want to sell a branded trolley jack without buying a generic mass-market product.
Quality and export background
Jiaxing Weiying Industry And Trade Co., Ltd. was established in 2004. Our factory area is between 10,000 and 30,000 square meters, and we have 51 to 100 employees supporting daily production.

This helps us keep production consistent for repeat orders and respond quickly to technical questions from your local service partners.
Frequently Asked Questions
1. Will the curved saddle completely prevent scratches on the car chassis?
No lifting tool can offer an absolute promise of zero scratches, but the curved saddle significantly reduces the causes of scratches. It replaces a sharp contact point with a broad surface that follows the body contour. Adding the optional rubber pad provides another layer of protection. As with any floor jack, the user should keep the saddle clean and always confirm that the lifting point is correct.
2. What types of vehicles can this trolley jack lift?
It is intended for passenger cars, sedans, hatchbacks, and compact SUVs. The exact lifting height and capacity must match the target vehicle. If you are importing for a fleet market or commercial vehicle segment, tell us the vehicle makes and models, and our factory will recommend the correct specification.
3. What is the maximum lifting capacity of this model?
We do not list a single fixed capacity in this product page because the final capacity depends on the frame size, hydraulic cylinder, and saddle configuration selected for your market. In normal passenger car service, capacities from 1.5 to 3 tons are common for floor jacks, but the actual value should be confirmed before mass production. Please send your required lifting capacity and we will provide a model recommendation.
4. Can I customize the saddle width and the rubber pad?
Yes. The curved saddle can be manufactured with different widths and radii. We can also install a replaceable rubber pad with standard or softer material. If you have a drawing or a sample of your existing jack, our production team can evaluate the adaptation cost and delivery time.
5. Is this trolley jack strong enough for daily workshop use?
The hydraulic system and frame are built for repeated workshop operations. The lifting arm and cylinder are protected by the frame structure, and the release valve gives the operator controlled speed when lowering. Regular maintenance, such as checking the oil level and cleaning the piston rod, will help maintain a long service life.
6. Can I buy with my own brand and instruction manual?
Yes, OEM and ODM programs are available. We can print your brand on the frame and carton, supply a customized user manual, and adapt the packaging for your distribution channels. For larger orders, we can also support spare parts planning and aftersales replacements.
7. How is the trolley jack packed for export?
The standard package is a strong export carton with internal protection for the saddle and hydraulic unit. For volume orders, units can be palletized or packed in wooden cases to reduce movement in the container. We can arrange shipment from Shanghai, Ningbo, Guangzhou, or Qingdao according to your forwarder’s plan.
8. What factory certifications and documentation do you provide?
Our factory has management system certifications including ISO 9001 and ISO 14000. When you send us a product model and destination country, we can share the relevant certificates and commercial documents. We are an experienced export manufacturer, so our team can support your registration, inspection, and quality audit requirements according to the market rules.
