Jiaxing Weiying Industry And Trade Co., Ltd., a manufacturer that has been producing hydraulic garage equipment since 2004, introduces the 50 Ton Heavy Duty Hydraulic Trolley Jack with Air Operated Pump Unit. This jack is built for workshops and service centers that regularly handle large machines, commercial trucks, and trailers. The thoughtful combination of 50-ton hydraulic power and a compressed-air-driven pump dramatically reduces manual effort, speeds up lifting cycles, and brings smoother load control to your maintenance floor.
Our factory is located in Jiaxing, Zhejiang, China, and covers a production area of 10,000 to 30,000 square meters. With more than 50 employees and annual exports of about US$1 million to US$1.5 million, we are ready to supply reliable lifting tools to customers around the world.

50 Tons of Lifting Power
The rated capacity of 50 tons makes this trolley jack a smart fit for repairing trucks, trailers, buses, agricultural machines, and many types of construction equipment. Instead of relying on multiple smaller jacks, a maintenance department can keep one versatile high-capacity trolley jack ready for the hardest jobs. The frame is designed to distribute heavy loads evenly, which is especially important when working with equipment that may not have perfectly balanced weight distribution. Using a jack with enough reserve capacity reduces the risk of sagging and improves the stability of the whole lifting operation.
Why Choose an Air Operated Pump Unit?
Manual hydraulic jacks are common, but they require slow and tiring pump actions, especially when moving big loads. This model uses an air operated pump unit to drive the hydraulic system. When the operator opens the air supply valve, the pump builds hydraulic pressure steadily and delivers lifting motion without physical pumping. This is a major time saver in high-volume workshops.
- Reduced operator fatigue for lifting tasks repeated throughout the day.
- Faster lifting performance compared with manual handle pumping.
- More consistent hydraulic flow for smoother raising and lowering.
- Designed for use with workshop compressed air systems; please confirm the air supply specification with our sales team.
Durable Construction and Practical Trolley Design
When you invest in heavy lifting equipment, durability matters. The structural frame of the jack is manufactured from heavy-duty steel, which gives it the rigidity needed to stand up to rough workshop conditions. The trolley-style chassis is equipped with swivel caster wheels and rear wheels, making it possible to move the jack across the floor and position it under a vehicle without excessive pushing and pulling. This is an important detail for operators who need to work quickly and avoid damage to floor surfaces.
Safety and Control for Heavy Loads
Lifting a 50-ton load brings serious responsibility. The hydraulic system includes an overload protection valve that helps guard against exceeding the rated lifting capacity. In addition, the release valve is built for controlled lowering, which prevents the load from dropping suddenly. We also recommend that operators work on level, solid ground, set the vehicle parking brake, and use appropriate jack stands whenever the lifted load will be held for an extended period. Always follow the instructions provided in the user manual and your local safety regulations.

Frequently Asked Questions
- Q1: What is the maximum lifting capacity of this trolley jack?
- The rated lifting capacity is 50 tons. For safe operation, do not exceed this load rating, and always make sure the vehicle or equipment is supported by proper jack stands when the load will remain elevated for a long time.
- Q2: How does the air operated pump unit work?
- The air pump unit connects to a workshop compressed air supply. The compressed air powers the hydraulic pump, which converts air pressure into hydraulic force to raise the jack. This removes the need for heavy manual pumping.
- Q3: Do I need a special air compressor to use this jack?
- The unit should be connected to a compatible air supply. Air consumption depends on the pump design, so we suggest sending us your air compressor specification when placing an inquiry and we can help you confirm compatibility.
- Q4: Is this 50-ton jack suitable for lifting trucks and trailers?
- Yes, it is designed for heavy-duty service work on large vehicles. However, the final choice should match the vehicle weight, lifting points, and the type of maintenance being performed.
- Q5: What is the lifting height range?
- The lifting range depends on the final configuration of the jack. Please request the detailed specification sheet from our sales team, and we will provide the minimum and maximum heights for the model you are interested in.
- Q6: Can we customize the color or add our own logo?
- Yes, customization options such as color choices and logo printing are available for qualified bulk orders. Contact us to discuss your branding and packaging needs.
- Q7: What safety features are included in this jack?
- The hydraulic system features an overload protection valve and a controlled release valve. Operators should also follow safe lifting practices, including using jack stands and working on flat, reinforced ground.
- Q8: What kind of after-sales support can we expect?
- Warranty and spare parts support are available upon request. We want to understand your application before recommending the best service package.
