Features of Hollow Ram Jacks Single Acting

Different models of single-acting hollow ram jacks are available in the market, depending on their capacity, stroke length, working pressure, and design features. Some standard features of single acting hollow ram jacks are:

Plain ram: It means that the piston rod has a smooth surface without any threads or attachments. Plain ram jacks are suitable for applications that do not require precise alignment or attachment of accessories.

Collar threads: These are threads on the outer surface of the cylinder body that allows for easy mounting of accessories such as eye nuts or clevises.

Base mounting holes: These are holes on the bottom of the cylinder body that allows for secure bolting of the jack to a flat surface.

Stop ring: This metal ring prevents over-extension of the piston rod and protects it from damage.

Safety valve: This valve releases excess pressure in case of overload or malfunction.

Applications of Hollow Ram Jacks Single Acting

Hollow ram jacks single acting have many applications in various industries, such as construction, mining, bridge building, heavy lifting, tensioning, testing, and maintenance.

Some of the common uses of hollow ram jacks single acting are:

Post-tensioning

Hollow ram jacks single acting can be used to apply tension to steel cables or rods that are embedded in concrete structures, such as bridges, dams, or buildings. The wires or rods are passed through the hole of the jack and attached to a wedge or anchor at one end. The jack is then pressurized to pull the cable or rod and create a compressive force on the concrete. It increases the strength and durability of the structure.

Cable splicing

Hollow ram jacks single acting can splice or join two sections of steel cables or wires. The cables or wires are passed through the hole of the jack and secured with clamps or grips at both ends. The jack is then pressurized to pull the cables or wires together and create a tight connection.

Flange spreading: Hollow ram jacks single acting can be used to separate two bolted flanges. The flanges are metal rings that connect pipes, valves, or other equipment. The jack is inserted between the flanges and pressurized to push them apart. It allows for easy access to inspect, repair or replace the equipment.

Bolt tensioning

Hollow ram jacks single acting can apply tension to bolts that fasten two components together. The bolts are passed through the hole of the jack and secured with nuts at both ends. The jack is then pressurized to pull the bolts and create a clamping force on the components.

Shaft extraction

Hollow ram jacks single acting can extract shafts stuck in bearings, gears, or other machinery parts. The rods are passed through the hole of the jack and attached to a puller at one end. The jack is then pressurized to pull out (or push out)the shaft from its position.

Advantages of Hollow Ram Jacks Single Acting

Hollow ram jacks single acting have many advantages over conventional hydraulic cylinders, such as:

• They can perform both pushing and pulling operations with one device.
• They can accommodate different sizes and shapes of loads by passing them through the hole.
• They can reduce space requirements by eliminating external attachments or accessories.
• They can increase safety by avoiding side loads or bending stresses on the piston rod.

Orione Hollow Ram Jacks Single Acting has a capacity range from 10 to 200 tons and a stroke range from 50 to 300 mm. They have a maximum working pressure of 700 bar and come with collar threads, base mounting holes, a stop ring, a safety valve, a dust seal ring, a wiper seal ring, coupler half set with a dust cap.

Safety Precaution

Single acting hollow ram jacks are versatile tools that can be used for various industrial applications. However, they also require proper maintenance and safety precautions to ensure optimal performance and longevity.

Some tips for using single acting hollow ram jacks are:

Single acting hollow ram jacks are powerful devices that can help you accomplish various tasks easily. By choosing the suitable model for your needs and following proper guidelines, you can enjoy its benefits for years.

• Use only recommended hydraulic oil and keep it clean and contaminant-free.
• void side or eccentric loads on the piston rod as they can cause bending or damage.
• se accessories that match the jack's capacity and thread size.
• Do not exceed the jack's rated capacity or stroke length.
• Do not use damaged or worn-out parts or hoses.
• Follow the manufacturer's instructions for operation and storage.
