Research areas

The main research areas at the department

Grapple mechanisms research (Surykin A.I., Rumyantsev B.P.).

Research of crane travelling and lifting mechanisms (Slyepchenko P.S., Gaidamaka V.F., Zhytnitskiy S.P.)

Research of braking mechanisms operation (Serdyuk V.P.).

To the research of problems of cranes metalwork were dedicated the works by professor, doct. of tech.sc. Zhermunskiy B.I.

Under the influence of the works by academician Proskura G.F. and on the initiative of professor Tamarin D.N. there also stems the direction in the research of hydrostatic and hydrodynamic transmissions in crane mechanisms.

For the first time this was realized in the candidate dissertation of Gaidamaka V.F. (presented in 1953), which is dedicated to the research of crain lifting mechanism with a hydrodynamic muff.

Later on, the scientific direction of hydrostatic and hydrodynamic drives was developed in the works by Losyev P.G. (presentation in 1964), Grigorov O.V. (presentation in 1969), Pashkina S.O. (presentation in 1970), Kovalenko V.A. (presentation in 1983), Petrenko N.A. (presentation in 1987).

Research works on electromagnetic powdered controlled muffs and brakes: Tomaryev V.O. (presentation in 1974), Rahmanniy A.S., Demkovskiy I.P., Kramer V.M.

The department provides technical support to many research and production organizations on the issues of scientific personnel training. Thus, at present there have been prepared for presentation 3 doctoral (by Spitsin I.O., Ostapenko V.I., Zhermunskiy B.I.) and more than 50 candidate dissertation theses (including that by the VNDIPTMASH director Komashenko A.H.).

The department maintained scientific and research connections with many enterprises of Kharkov and other cities: HTE factory, turbine plant, KhEMZ, “Serp i Molot” (all Kharkov); “Zaporizhsteel”, Mariupol sea-port, Norilsk ore-dressing plant, Belgorod cement plant, Klaipeda sea-port, Rzhevsk crane-building factory, Uzlovaya machine-building factory, SKMZ, Khartsizk rope factory, Lviv factory “Conveyor”, Donetsk foundry, HTE factory in Donetsk, experimental HTE plant in Kharkiv.

The coordinators of contract-based research and post-graduates’ consultants are: Zhermunskiy B.I., Gaidamaka V.F., Grigorov O.V., Kovalenko V.O., Svirgun V.P.

A new research is optimum crane mechanisms operation. In this theme there has been successfully presented a dissertation by Svirgun V.P. (1989). Considerable attention to the problem of optimum operation has been paid in O.V. Grigorov’s dissertation thesis (presented in 1995).

The main modern directions in research

  • Cranes modernizing and automation of their work by applying microprocessor control.
  • Cranes’ dynamics.
  • Crane drives (electromechanical, hydrostatic, hydrodynamic, frequency regulated). Experimental load analysis, e.g. of the drive, girth construction (of a bridge).
  • Logistics.
  • Load-lifting machines.
  • Construction machines.
  • Microprocessor optimal control of one crane or a group of cranes.
  • Energy saving in hoisting and transportation, construction, and road machines.
  • Expert inspection of load-lifting cranes.

The department has performed and introduced the following works:

  1. There have been designed and carried out the hydrodynamic transmissions researches for:
    • Travelling mechanisms for bridge cranes and carriages (crane with lifting capacity of 30/5 tons, Kharkov, and 20/5 tons crane at Uzlovaya machine building plant, Tula area, Russian Federation);
    • Turning mechanisms (tower crane with lifting capacity of 9.3 tons, Kharkov, and portal 6.3 tons crane, Klaipeda, Lithuania);
    • Travelling mechanisms for tower cranes (tower crane with lifting capacity of 10 tons, Rzhevsk tower cranes factory, Tver area, Russian Federation);
    • Coupled turn mechanism of a tower crane (tower crane with lifting capacity of 10 tons, Rzhevsk tower cranes factory, Tver area, Russian Federation).
  2. There have been designed and carried out the researches of volume regulated drives and automatic control systems for:
    • Travelling mechanisms for bridge cranes (crane with lifting capacity of 75/20 tons, Kramatorsk, Donetsk area, and crane with lifting capacity of 30/5 tons, Kharkov, as well as crane with lifting capacity of 15/3 tons, Uzlovaya, Tula area, Russian Federation);
    • Turning mechanism of a “Kirovets” portal crane with lifting capacity of 10 tons, Kyev river port.
  3. There have been designed and realized the projects of microprocessor systems for optimum operation of one (Kharkov house-construction plant) and a group of bridge cranes (Khartsizk Steel-wire cable factory, Donetsk area), as well as electric hoists (the department’s laboratory) with flexible cargo suspension. There have been designed and tested in industrial conditions and on department’s test-tables systems for optimum automatic control.
  4. Researches of dynamic loads within mechanisms’ elements have been performed.
  5. Automatic design systems for load-lifting machines’ elements have been developed, in particular those for bridge cranes, and drag-type conveyors.
  6. Various electromagnetic powder muffs and brakes for bridge, full gantry cranes and systems for their control have been designed and tested on real cranes.
