What is a hydraulic trailer jack?
The difference between two-antenna and three-antenna jacks
Hydraulic jack with two antennas
- Simple and reliable structure
- Suitable stability during load bearing
- Ease of service and replacement of parts
- Suitable installation space in all types of chassis
- Controllable performance in different working conditions
Three antenna hydraulic jack
- Access to greater height
- Usability in high trolleys
- Suitable for situations where installation space is limited
- Better folding than jacks with a fixed length
- More flexibility in connecting and disconnecting operations

Technical services and parts supply
Technical support and the possibility of supplying consumable parts are very important. Buying from a specialized collection such as Novin Jack can simplify access to technical advice, compatible parts and after-sales service.
The correct way to install a hydraulic trailer jack
The installation of two and three antenna trailer hydraulic jacks should be done by a person familiar with the chassis and hydraulic system. First, the installation site should be checked for resistance, alignment and distance from moving parts. The jack should not be placed in a way where it collides with the axle, suspension system, brake hose or other components.
After mechanical installation, the route of the hoses should be selected in such a way that it is not subject to stretching, abrasion, extreme heat or contact with foreign objects. Fittings should be fully tightened, but over-tightening can damage the thread or body.
In the next step, the appropriate hydraulic oil is placed in the system and the trapped air is removed from the track. The presence of air in the circuit can cause unstable movement, loss of power and noise. After venting, the jack is tested several times without load and then with a controlled load.
Hydraulic jack maintenance and service
Regular maintenance increases the life of the two- and three-antenna trailer hydraulic jack. Visual inspection should be performed at regular intervals to quickly detect signs of oil leaks, cracks, rust, wear, or loose connections.
The surface of the antennas must be clean and no mud, dust or abrasive materials remain on it. Contamination entering the cylinder can cause the seals to fail. Also, the hydraulic oil should be checked for contamination, discoloration, and reduced surface area.
If you see the gradual lowering of the jack under load, there is a possibility of an internal leak in the valve or cylinder. Slow motion may also be caused by blocked track, lack of oil, pump failure, or air entering the circuit. In this situation, the repairman must check the root cause and prevent unnecessary replacement of parts.
Why Novin Jack is the right choice?
Novin Jack, focusing on hydraulic equipment and jacks used in heavy vehicles, tries to provide products that meet the real needs of the market. Knowing the structure of the trailer, the working conditions of the fleet and the importance of safety in transportation are important factors in choosing and supplying the right jack.
At the time of buying a two and three antenna trailer hydraulic jack from Novin Jack, paying attention to the technical specifications, installation dimensions, load bearing capacity and type of use allows for a more accurate choice. Expert advice before purchase also helps to choose a product suitable for the chassis and conditions of use.
The advantage of a specialized supplier is not only limited to product sales. Providing clear technical information, guidance for installation, supply of consumables and investigation of performance problems is an important part of the service that a professional assembly should provide to the customer. Novin Jack can be a viable option for providing hydraulic jack equipment for transport fleets, repair shops and industrial complexes.
summary
The two and three antenna trolley hydraulic jack plays an important role in connecting, disconnecting, adjusting the height and maintaining the trolley. The two-antenna model is usually suitable for general applications and medium heights, while the three-antenna model is more useful for higher trolleys or situations where the installation space is limited.
For the right choice, load bearing capacity, closed and open height, number of antennas, quality of internal parts, installation method and access to technical services should be checked. Regular maintenance, oil control, leak checking and use of a stable surface also have a direct effect on increasing the safety and longevity of the product.
If you are looking for two and three antenna trailer hydraulic jacks with appropriate technical specifications and specialized support, Novin Jack can be one of the right options to check and provide this equipment. Choosing a product from a specialized collection reduces the possibility of incompatibility with the chassis and costs of subsequent repairs, and provides more reliable operation for the transport fleet.
