Also known as 2-ton hydraulic jacks, these tools use liquid mechanics to lift heavy loads during maintenance tasks. The jacks have two ports, a pump and a release port connected by a pipe filled with hydraulic fluid. When the pump port is depressed, the fluid pushes the piston at the release port, moving it upward and lifting the load. The piston at the release port pushes fluid back into the pump chamber when the piston is pushed down, creating pressure that lowers the piston to its original position.
2-ton hydraulic jacks come in different types, including:
Floor jack
Allied hydraulic floor jacks are commonly used to lift vehicles during repair and maintenance. The jacks have a saddle that supports the load and a pump mechanism that raises the saddle. A handle pushes the pump piston up and down, creating pressure that raises the saddle.
Service jack
Allied hydraulic service jacks have a large lifting capacity and are mainly used in garages to lift heavy trucks and buses. The jacks have a simple design with a lifting mechanism that is easy to maintain and repair.
Bottle jack
Hydraulic bottle jacks have a small and compact cylindrical shape. The jacks are portable and can easily fit under a load. They are mainly used to lift vehicles during tire changes. The bottle jack's vertical lifting mechanism limits its use in tasks that require the load to be raised and moved across.
Railway jack
Allied hydraulic railway jacks are designed to lift railway tracks and rolling stock. The jacks have a robust design with a high lifting capacity, making them suitable for heavy industrial applications. They also have safety features such as load-holding valves to prevent accidents during lifting.
Toe jack
Allied hydraulic toe jacks have a small and compact design with lifting arms and toes, making it suitable for lifting loads in tight spaces. The jacks are often used to lift heavy machinery and equipment during installation and maintenance.
Allied hydraulic jacks are jacking machines that use liquid hydraulics to lift heavy loads or vehicles. Hydraulic jacks are widely used in construction and civil engineering. The basic construction of the hydraulic jack is the two-cylinder system interconnected by a pipe filled with liquid. The two cylinders have different cross-sectional areas. One cylinder, which is the pumping cylinder, has a small cross-sectional area. Operators apply a small force on the pumping cylinder to lift the load on the other cylinder, which has a large cross-sectional area.
The 2-ton hydraulic jack is designed to lift vehicles that weigh up to 2,000 pounds. Some of the specifications of the hydraulic jack include the following:
To ensure the hydraulic floor jack is in good working condition and ensure safety during operation, here are some maintenance tips:
There are several factors to consider when choosing a suitable hydraulic floor jack for any given situation. These factors include:
Allied hydraulic jack capacity
The hydraulic jack's capacity refers to the amount of weight it can lift safely and efficiently. When choosing a hydraulic jack, consider the weight of the vehicle and add a safety margin. For instance, if a vehicle weighs 3,000 pounds, the hydraulic jack should be able to lift at least 3,600 pounds. The added weight gives room for errors and ensures safety.
Allied hydraulic jack height and lift range
Different hydraulic jacks have different heights and lift ranges. Choose a hydraulic jack with a height that can comfortably fit under the vehicle. Also, consider the lift range. Some vehicles need a higher lift than others.
Allied hydraulic jack weight and portability
Some hydraulic jacks are heavier than others due to the materials used to construct them. Choose a hydraulic jack that is lightweight and portable. A portable hydraulic jack is easy to carry around and can be used in different situations.
Allied hydraulic jack stability and safety
When choosing a hydraulic jack, consider its stability. The hydraulic jack should not tip over when lifting a vehicle. Also, look for safety features such as overload protection and safety stands.
Allied hydraulic jack construction material
The hydraulic jack's construction material affects its durability, weight, and portability. Common materials used to make hydraulic jacks include steel and aluminum. Hydraulic jacks made of steel are more durable than those made of aluminum. On the other hand, hydraulic jacks made of aluminum are lighter and more portable than those made of steel.
Most hydraulic jacks are simple to repair. This is because, as noted earlier, the majority of the errors are associated with low oil levels or with the pump, which is very easy to access. Before attempting to repair a hydraulic jack, the user should always read the service manual. Here are some steps on how to DIY and replace 2-ton allied hydraulic floor jack:
Check the Service Manual
The service manual contains important information about the hydraulic jack model. It has data on the construction, the hydraulic circuit, and the repair processes. The manual also has troubleshooting guides and possible error fixes.
Inspect the Jack
The jack should be inspected to determine the level of damage. Is it a mechanical failure, or is there fluid leakage? If it is a mechanical failure, the jack should be opened to inspect the internal components. If there is leakage, then the fluid should be topped up and the leak fixed.
Fluid Replacement
When changing the hydraulic fluid, the specifications on the service manual should be used. The new fluid should be purged of air bubbles before pouring. The Level should be topped up to the indicated mark.
Reassemble and Test
After all the repairs are done, the hydraulic jack should be assembled back per the instructions given in the service manual. Before the jack is closed, all the components should be cleaned, and the O-rings lubricated. The jack should be tested to ensure it is working properly.
Q1: Can the hydraulic jack be repaired?
A1: Yes, the hydraulic jack can be repaired. However, it is advisable to use a professional to maintain the jack, especially if it requires disassembly.
Q2: How long does a hydraulic floor jack last?
A2: With proper maintenance, a hydraulic jack can last between 5-10 years. The longevity of a hydraulic jack also depends on its quality and how frequently it is used.
Q3: Why does a hydraulic jack lose pressure?
A3: A hydraulic jack loses pressure due to several factors, including internal leakage, oil level being low, air contamination, and oil being contaminated.
