[About. Russian] Technology of construction of cable-stayed bridge

   

Hydraulic equipment "Ehnerprom" designed and manufactured to equip the machine installation of the channel span of the bridge on about. Russian.

Specifications mounting the unit:

  • 400 ton lifting capacity,
  • rate of climb, m / s (ft / min) 0,013 (0.8)
  • height 80 m

The hydraulic system assembly unit is designed for lifting, moving, installation and adjustment of the machine lifted them to coordinate the metal block span in the axes of XY.

 

 

The hydraulic system assembly unit includes:

  • hydraulic jacks Lift the rear of the unit (1) a force of 100 ton, operating pressure of 32 MPa;
  • jacks lifting the middle part of the unit (2) a force of 200 ton, operating pressure of 32 MPa;
  • cylinders moving and handling (3), 4000 mm stroke, the force pushing the 32 ton;
  • cylinders longitudinal movement of the object being lifted (4), a force of 50 ton, stroke 2500 mm;
  • cylinders lateral movement of the object being lifted (5) Efforts to 50 ton, stroke 250 mm, and
  • cylinders the angular displacement force of the lifted object 30 ton, the stroke 500 mm arranged on a traverse (6).

    Hydraulic cylinders are made in designs with chrome rods, using a system of seals and wipers against the ice, with protective covers for stocks.

    Power supply hydraulic working fluid is 4-pumping stations, two of them IEE (16-32)-MA, electric, mounted on the beam transverse beam and the bottom of the unit (7), and two, NED1625-MA, diesel driven, on the traverse lifted object (6), equipped with redundant radio controls (on the mounting unit and on the pontoon).

    Management jacks and hydraulic cylinders perform гидроэлектрораспределителей blocks. Pumping stations are assembled using hydraulic components Bieri (Switzerland) and Yuken (Japan), the control system with the use of frequency converters.

    Lines are made with steel pipes DN8 and DN10 for steel unit. Supply of hydraulic cylinders and hydraulic lines to the Rams’ high pressure hoses made of high quality rubber Yokogama with the double margin and increased wear resistance, with quick couplings. Total length sleeveless kit for mounting the unit approximately 630 m
