A double ram jack is a hydraulic lifting tool used in various industries. It has two rams, which push out simultaneously when the pump handle is pressed. The two rams provide more lifting power and stability. Below are some of the main types of double ram jacks.
Double Ram Hydraulic Jack
The double hydraulic ram jack has two hydraulic rams. It can lift heavy loads and provide stable support. The lifting height is also large. This jack is commonly used in construction, mining, and metalworking industries.
Double Ram Low Profile Jack
The low-profile double ram jack has a low height. This jack is suitable for narrow workspaces. It is used to lift heavy machinery, trucks, and buses. The lifting speed of the low-profile double ram jack is also fast.
Double Ram Welded Construction Jack
The welded construction double ram jack is made using welded parts. This increases the strength and durability of the jack. This jack is used in the oil and gas industries, as well as heavy fabrication.
Double Ram Telescopic Jack
The telescopic double ram jack has telescopic rams. The length of the rams can be adjusted. This jack is used in applications that require lifting at different heights. The double ram telescopic jack is used in aerospace, shipbuilding, and assembly line operations.
Double Ram Safety Lock Jack
The safety lock double ram jack has a safety locking mechanism. This prevents accidental load drop during lifting. This jack is used in construction, maintenance, and heavy lifting applications, where safety is paramount.
Any hydraulic double ram jack is designed with important specifications that provide lifting power for heavy loads. The hydraulic lifting tools incorporate the pressure difference between the two pistons. Some of the general specifications include the following.
Like any other hydraulic equipment, proper maintenance of double ram jacks is paramount. Proper maintenance ensures safety and improves the lifespan of the hydraulic jack. Here are some of the maintenance tips for the hydraulic double ram jack.
When buying a double ram jack, people need to consider several factors to ensure they get the right equipment for their needs. Here are some key points to keep in mind:
Capacity
Choose a double ram jack with a lifting capacity that matches or exceeds the weight of the vehicles or equipment that will need to be lifted. Overloading the jack can cause accidents and damage.
Lift Height
Consider the maximum lift height of the double ram hydraulic jack. The lift height should be sufficient to provide enough clearance for maintenance or other tasks.
Construction
Look for a double ram jack made from high-quality materials such as steel or aluminum. The construction material should be durable, impact-resistant, and corrosion-resistant.
Portability
If the jack needs to be moved from one place to another or used in different locations, consider its size, weight, and portability. Some models come with wheels or handles for easy transportation.
Safety Features
Safety features are essential when choosing a hydraulic ram jack. Look for jacks with overload protection, safety valves, non-slip lifting pads, and sturdy construction to reduce the risk of accidents.
Stability
Consider the stability of the double ram truck jack during lifting operations. A wide base or anti-tip design can help ensure the jack remains stable and secure when lifting heavy loads.
Ease of Use
Choose a jack that is easy to operate and use. Consider the effort required to lift and lower the load, the jack's grip, and the control mechanism's convenience.
Warranty and Support
Check the warranty period and after-sales support offered by the jack manufacturer. A longer warranty and reliable customer support can provide additional assurance of product quality and reliability.
Price
Consider the hydraulic ram jack price but avoid choosing the cheapest one. Compare the features, performance, and safety of different models to find the best value-for-money jack.
By considering these factors, people can choose a double ram jack that meets their needs, ensuring safe and efficient lifting operations. Remember to read the user manual and follow the manufacturer's instructions for safe use and maintenance of the double ram jack.
Some hydraulic jacks have two cylinders, while others have one. The ones with two cylinders are called double ram jacks. They work just like the single ram jacks, but the lifting capacity is higher because the oil moves through two cylinders. When the double ram jack needs repair, the procedure is pretty straightforward.
To repair a hydraulic jack, the user needs to open up the tool and see what is wrong. If the problem is from the cylinders, then the user needs to replace them. Before replacing the cylinders, it is important to note that repairing and replacing hydraulic jacks are more cost-effective than buying a new one.
This guide will take the user through some basic steps on how to replace a double ram jack.
Safety Precaution
Before carrying out any repair, it is important to take safety precautions into consideration. Disconnect the jack from the power source if it is an electric jack. If it is a manual jack, ensure it is clean and free from debris.
Gather Tools
Users should have all the necessary tools within reach, such as screwdrivers, replacement parts (cylinders), and sealants. Make sure to read the manufacturer's manual to know what tools to use for the repair.
Disassemble the Jack
Carefully, use a screwdriver to unscrew the jack and open it up. Take note of how the internal parts are arranged so that it will be easy to reassemble them after the repair.
Inspect and Replace
Inspect all the internal parts of the jack to know what is wrong with them. If there are any worn-out parts, replace them with the new ones. Remember to use the same size and specification as the original part.
Reassemble
After the replacement, carefully assemble all the parts back together using the screws and sealant.
Test
Before using it for any lifting tasks, make sure to test it to see if it is working perfectly.
Q: Can a double ram jack be used for lifting heavy machinery?
A: Yes, a double ram jack can lift heavy machinery. However, it is important to ensure that the jack's lifting capacity exceeds the weight of the machinery to be lifted.
Q: How often should a double ram jack be serviced?
A: The frequency of servicing a double ram jack depends on its usage. However, it is recommended to service it at least once every six months or after 1000 lifts, whichever comes first.
Q: Can a double ram jack be repaired if the cylinder is damaged?
A: Yes, a double ram jack can be repaired if the cylinder is damaged. However, it is important that the repair be carried out by a qualified technician to ensure safety and compliance with standards.
Q: Is it necessary to use a safety stand when using a double ram jack?
A: Yes, it is necessary to use a safety stand when using a double ram jack. The safety stand provides additional safety by preventing accidental drop during service or maintenance.
