Universal hydraulic jacks DGU-10, DG-25, DG-50, DG-100, DG-150, DG-200, DG-500

   Universal hydraulic jack DG is designed for construction, repair, assembly and dismantling works. Professional hydraulic jacks allow to securely and smoothly raise and lower all kinds of goods and loads both with a single jack and within the system of simultaneous lifting which is often used in such kind of industries as heavy engineering,  gas, oil pipelines laying,  bridges construction.

    With technical progress, hydraulic jacks of various lifting capacity became one of the most popular lifting equipment on a par with gantry cranes. Hydraulic jacks have truly fantastic power in comparison with their small size, they are reliable and easy to maintain.

    JSC "Kubanzheldormash" is one of the major manufacturers of hydraulic lifting jacks for the industrial purpose. Powerful jacks with a hydraulic drive are widely used during installation of heavy industrial machines, equipment, turbines, reactors and military structures.

Operation principles of hydraulic jacks

    The main operation principle of any hydraulic jack is based on the idea that the pump creates pressure of working liquid which is pushing the plunger(piston) and due to this process the load is being lifted. If it is necessary to lower the load, just open the pressure relief valve and hydraulic oil will flow back into the oil tank. Lifting capacity of heavy hydraulic jacks varies from 25 to 500 tons depending on heaviness of construction which is needed to lift.

  Among other advantages of hydraulic jacks are the use of incompressible hydraulic oil and high-effective ratio of significant loading capacity and minor force at the handle of the hydraulic pump. Besides the smoothness of the work stroke and compact design, all hydraulic jacks have a fairly high efficiency coefficient.

Field of use and operation features

    The construction and overall dimensions of hydraulic jacks allow to move the jacks inside the construction site without any difficulty. The field of use can be quite various. Sufficient lifting height and mobility of all kinds of hydraulic jacks make them universal means of lifting loads with different sizes and weight.



   Universal hydraulic jack DGU-10 is intended for lifting rail-sleeper lattice during the maintenance and reconstruction of the railway track. It can work as a jack and as a rail flattener, it also can be used in all planes. That is why this jack is so popular among installers, rescuers and builders. It is often used for moving equipment, smoothing out dents and bending metal-roll. This jack has become an indispensable instrument at construction sites, during installation and dismantling works, rescue operations. Compact design, weight of 20 kg and 10 tons stroke power made this tool an ideal decision for lifting various loads and flattening various thick and rigid metal structures. Also compact design with built-in pump allows to use the universal hydraulic jack DGU-10 in cramped conditions. 

   Hydraulic jack DG-25 due to its simple and reliable construction as well as its compactness and low weight of 25 kg is optimally suitable for industrial and construction operations. Lifting capacity of the jack DG-25 is 25 tons, which gives a lot of opportunities for solving various tasks. Built-in shaft of hydro pump is manual, which allows to use it in small spaces. As any other hydraulic jack of our production, DG-25 is equipped with a safety valve which protects it from overloads.

   Hydraulic jack DG-50 is among jacks with built-in hydro shaft. This jack should be considered as an optimal decision by its "compactness / load" ratio. Most often this jack is bought for repairing agricultural and road building machinery as well as for construction of roads and railways.

 

   Hydraulic jacks DG-100 and DG-200 are the golden mean between general industrial jacks with lifting capacity of 10, 15, 20, 50 tons and real heavyweights for special needs with lifting capacity 300,400 and 500 tons. Hydraulic jacks DG-100 and DG-200 with lifting capacity 100 and 200 tons are mostly used by oil and gas industries, who are laying large diameter pipes. Also these jacks have great popularity among bridge builders who are building and repairing various bridge structures, gateways, viaducts, overpasses, and so on.

   Hydraulic jacks DG-300, DG-400, DG-500 are industrial heavy jacks with high lifting capacity for solving narrowly specialized tasks. Work with such kind of powerful jacks implies the presence of knowledge in hydraulics, because this is really high pressure, which creates an enormous force. Jacks with lifting capacity 300, 400 and 500 tons are truly industrial jacks for professionals, who are engaged in construction of large and complex structures. All the models of jacks have two built-in safety valves,one in the head end and the second one in the rod end

    Main customers of hydraulic jacks historically are coal, oil, gas, metallurgy, energy and petrochemistry industries as well as bridge builders, trackmen, special construction and rescue services.
