As a manufacturer established in 2004, Jiaxing Weiying Industry And Trade Co., Ltd. offers this industrial hydraulic trolley jack for workshops, garages, factory maintenance lines, and mobile service teams. With a rated lifting capacity of 3 tons, a 360° swivel caster set, and a reinforced welded steel chassis, this jack is designed to provide stable, efficient lifting in everyday working conditions. We combine a factory area of 10,000-30,000 square meters with an experienced in-house team of 51-100 employees, supporting consistent production for both standard and custom orders. This product is especially suitable for users who need a movable, strong, and easy-to-position lifting tool for vehicles, trailers, machinery, and plant equipment.
Product Overview
The trolley jack is built around a reinforced welded steel chassis. This construction method gives the frame a more rigid base than many light stamped floor jacks, helping to reduce deflection when the saddle is under load. The integrated 360° swivel caster set allows the jack to be moved in different directions, including sideways, which makes it easier to align with the lifting point of a car, truck, or machine. The hydraulic pump and cylinder assembly is sealed with high-pressure oil and works through a smooth pumping action, allowing the operator to raise the load to the desired height and lower it in a controlled manner. These functional features make the unit well suited for daily service and maintenance operations.
Key Features and Benefits
Reinforced welded steel chassis: The frame uses heavy steel sections and welded joints that are designed to resist bending and torsional stress during lifting. This reduces wobble and helps the jack remain stable.
360° swivel caster set: The caster arrangement enables smooth turning and positioning. Operators can rotate the jack on the spot or move it sideways to reach a tight lifting point.
Smooth hydraulic lifting system: An oil-sealed hydraulic pump raises the piston with limited effort, giving a steady lifting motion even when a heavy load is applied.
Controlled lowering valve: The release mechanism is designed to allow gradual lowering of the load. This improves safety and prevents sudden impact when completing a maintenance task.
Operator-friendly handle: The steel handle can be used for steering and pumping, and its length is suitable for comfortable operation in most workshop layouts.
Low-maintenance design: The main pivot points and caster wheels are easy to inspect. Keeping the unit clean and lubricated will help extend its service life.
Customizable details: Paint color, packing method, caster type, and labeling can be arranged according to buyer requirements. All custom options are subject to order quantity and technical feasibility.
Hydraulic Performance and Operation
The hydraulic system works by pumping oil from an internal reservoir into a cylinder, which pushes the piston upward. The lifting speed is controlled by the number of pump strokes, and the lowering speed is controlled by a release valve. Operators should inspect the hydraulic unit before each shift to ensure there is no oil leakage and that the piston rod is clean. If the jack is used outdoors, it should be positioned on firm ground. The jack must not be used as a support device for prolonged tasks; once the load is lifted, jack stands or another approved support should be placed under the equipment.

Typical Applications
This 3-ton hydraulic trolley jack is suitable for general lifting tasks in environments where mobility and compact storage are important. Common uses include:
Tire removal, brake inspection, and suspension service for passenger cars and light utility vehicles.
Maintenance of trailers, small agricultural tools, and light commercial vehicles.
Lifting machine bases, beds, or frames during installation and alignment in workshops.
Supporting mobile service crews when no workshop lift is available.
Maintenance Guidelines
To keep the jack in dependable condition, check all fasteners, cotter pins, and caster mounting bolts at regular intervals. Clean the hydraulic piston and wipe away dust before each use. If the jack shows signs of leakage or reduced lifting power, replace the hydraulic oil according to the recommended grade in the manual. Store the jack in a dry area with the lifting arm fully lowered so the piston rod is not exposed. Replace worn casters with components that match the original diameter and load rating.

Frequently Asked Questions
What is the rated lifting capacity of this jack?
This model is rated for 3 tons. Always check the load limit printed on the jack and confirm the weight of the vehicle or equipment before lifting. Do not exceed the stated capacity.
Can the caster set really rotate in all directions?
The caster set is designed for 360° swiveling, allowing easy movement forward, backward, sideways, and turning in tight workshop areas. This improves positioning accuracy when preparing to lift a load.
Is the steel frame strong enough for everyday industrial use?
The chassis is made from reinforced steel sections with welded assembly. The welded construction provides a rigid platform that helps spread the load during lifting and is intended for frequent service tasks within the rated capacity.
Does the hydraulic system require regular maintenance?
Yes. The hydraulic oil should be checked and changed according to the manual. Keep the unit free of dirt and moisture, and inspect the pump and cylinder for leaks. Regular maintenance helps maintain smooth lifting and extends the service life.
What safety steps should be taken before using the jack?
Place the jack on a level, hard surface, center the load on the saddle, and ensure there are no people near the raised load. Use approved jack stands to support the load before starting work. Release pressure slowly and use the handle to control the lowering speed.
Can we customize color, logo, and packaging?
Customization is possible for approved order quantities. Buyers can request a specific paint color, logo marking, caster style, or packing method. Our sales team will confirm feasibility and lead time before final quotation.
Which shipping options can be arranged?
We ship from Shanghai, Ningbo, Guangzhou, or Qingdao. Sea freight is a common option for full or consolidated containers, and express or air freight can be discussed for samples or small orders.
