Single-acting hydraulic pull cylinder

Equipped with a stop ring to prevent the plunger from coming out of the cylinder.

It is possible to perform lifting operations of large heavy objects without using cranes or similar equipment.

Using a sturdy and durable road skate makes it possible to move heavy objects safely and easily.

This is a mechanical jack for raising and lowering electric wire cable drum reels. It comes in four types that can accommodate cable drum reels of various sizes. Being a manual mechanical operation, it does not require power and can be used safely and easily. It has a lifting and lowering capacity ranging from 44 to 178 kN.

We offer a lineup of 8 models of manual jacks for lifting heavy loads using a rack, with capacities ranging from 44 to 133 kN. The ratchet jack is manual, meaning it is a mechanical jack that does not require power. Available in steel and aluminum, you can choose based on your application. Being mechanical, it can safely support loads for extended periods.

The journal jack is a durable screw-type mechanical jack. We offer eight types ranging from 133 to 445 kN. The handle operation is light, allowing for smooth jacking strokes. The lifted load or weight is mechanically held, so there is no need to worry about the stroke dropping.

By simply turning the screw manually, leveling can be easily achieved. The load cap at the tip of the screw has a tilt structure, allowing the cap to follow up to a 10° angle relative to the work, so you can use it with confidence.

The "MLS Series" is a wheeled road skate that allows for the safe movement of various heavy equipment. With the steerable skate from MLSF, you can easily operate it with a turntable that allows for smooth rotation even under load, making it suitable for general applications. Additionally, we offer products such as the "Nylon Wheel Kit," which is ideal for reducing wear resistance and increasing capacity, as well as the "SOH Series, Machine Lift" and "LW Series, Lifting Wedge." 【Features】 ■ Low profile allows for lifting and moving with minimal effort ■ MLSR rotating skate enables 360-degree directional changes, providing high versatility and suitability for tight spaces ■ Models equipped with nylon wheels are available upon request ■ Handles and connecting bars can be attached to the MLSR set according to application needs *For more details, please refer to the PDF materials or feel free to contact us.

In 2013, Jakarta, the capital of Indonesia, began construction of a Mass Rapid Transit (MRT) system with the expectation of alleviating the city's traffic congestion. One of the critical stages of tunnel construction is the pass-through. In this pass-through, it is necessary to move the Tunnel Boring Machine (TBM) through the underground station to the next excavation site, which requires a high-precision system to handle the heavy loads with uneven weight distribution. Therefore, Ekatama Group used a synchronized lifting system and hydraulic jacks to lift and slide the TBM with an accuracy of 1mm throughout all positioning operations. The stroke sensors at each lifting point generated real-time updates, measuring the displacement of the load to maintain an accuracy of 1mm. *For more details, please refer to the PDF document or feel free to contact us.*

Minimizing the time that State Route 266 is closed was a primary objective when reconstructing the bridge over the Holbrook Canal. The new bridge was initially used as a detour while the defective bridge was being demolished, but once the old bridge was taken down, the new bridge needed to be slid into place at the original bridge's location. To achieve this, Enerpac provided a hydraulic solution that could push the new 44.5-foot bridge structure into position using a lateral sliding method with PTFE slide elements. The slide was completed in 52 minutes. **Case Summary** - Customer: Kiewit (United States) - Products: RR Series double-acting hydraulic cylinders, ZU Series hydraulic pumps - Result: The slide was completed in 52 minutes. *For more details, please refer to the PDF document or feel free to contact us.*

Changing a flat tire on heavy machinery is one of the particularly dangerous and time-consuming maintenance tasks in underground mining, often taking up to 12 hours to complete in limited spaces with inclines. CME Boilermaking, a leading engineering and manufacturing specialist in Australia, has designed an efficient solution that allows vehicles to be manually jacked up for safe and reliable lifting and maintenance. The company's underground jack system is connected to the Enerpac XC series cordless hydraulic pump and RAR series durable lightweight aluminum cylinders, capable of handling loads of up to 100 tons. "The Enerpac battery pump is the perfect solution, as the absence of cords enhances operator safety," it has been praised. *For more details, please refer to the PDF materials or feel free to contact us.*

The renovation of a historic building in the capital of Georgia required lifting a 3.4-meter-high steel tower. To achieve this, a 16-point SyncLift system and 39 hydraulic jacks were used to synchronously lift the building onto the pylons. Pylons measuring 5.5 meters in length were driven into the concrete foundation from the first floor, with brackets and double-acting hydraulic jacks mounted on top of each pylon. Four threaded steel rods were passed through each pylon bracket and connected to the structure supporting the building's foundation. Additionally, the SyncLift system allowed the operator to monitor and control all jacks from a single touchscreen controller. *For more details, please refer to the PDF document or feel free to contact us.*

At Oyu Tolgoi, one of the largest known copper and gold deposits in the world, there was a need to install steel linings in vertical ore bodies with a maximum diameter of 3 meters and depths of 30 to 70 meters, and they were looking for a safe and reliable solution that provides precision and synchronized control. Enerpac strand jacks are powered by electric or diesel-driven hydraulic power packs and are fully controlled by the unique SCC-Smart Cylinder Control System for lifting operations. These are ideal for customers seeking accurate synchronized control with the capability to lift heavy loads in an economical, compact, and reliable installation footprint. The company used four "HSL7006 strand jacks" for the installation of the steel linings. With automatic lock/unlock operations, the system is controlled by one operator from a central location, enhancing safety. It not only strengthens synchronized control during descent but also allows for fine adjustments while descending to remove obstacles during installation. *For more details, please refer to the PDF document or feel free to contact us.*

The ocean production facility is expected to be constructed in the Gulf of Mexico, positioned at a depth of over 5,000 feet. To build the tension leg platform, it was necessary to slide approximately 7,000 tons of modules into place. The "Enerpac strand jack" was used for loading utility, drilling, and process modules, providing a pulling force of 1,500 tons during the loading procedure.
