The bridge grab crane was manufactured for a large Ukrainian thermal power plant

For a large Ukrainian thermal power plant at the «Kyiv Crane Machinery Plant LLC», a grab crane of model KMg-5.0-15.45.45.0.0-A6 was designed and manufactured.

This TPP uses highly efficient innovative technology for the production of heat and electricity using powerful solid fuel and gas boilers. At the same time the work of solid fuel boilers is carried out due to the combustion of pellets from straw, wood chips, peat and other similar materials. The fuel burns in the boiler, whereby the water is heated and converted to steam. The resulting steam drives the turbines, which convert heat into mechanical energy, which, in turn, drives the generators that generate electricity.

It was for the loading of pellets into new, additional boilers, and the power engineers needed a lifting crane that was ordered from our plant. Immediately after getting acquainted with the technical assignment, a group of factory specialists (as part of the regional manager, designer and chief of the installation and installation service) visited the TPP in order to familiarize themselves on the spot with the conditions in which the new lifting crane and the features of the section where it was to be installed should be operated.

Such a solid approach to solving the upcoming task allowed the factory designers to develop a draft grab crane in a very short period of time, which would be the most optimal for the specifics of the Customer’s working site. A phased work plan was developed. All crane equipment was manufactured and delivered to the facility in the agreed time. After installation of the bridge grab crane, all necessary tests were carried out, including statistical and dynamic tests. It is significant that the installation, commissioning and testing of the new crane machine took only 5 working days.

Main technical characteristics of the new grab crane:

  • loading capacity - 5 t;
  • lifting height - 12.0 m;
  • crane span - 15.45 m;
  • lifting and lowering speed - 0 ... 12 m / min;
  • trolley speed - 0 ... 30 m / min;
  • speed of movement of the crane - 0 ... 40 m / min;
  • group mode of operation according to ISO or GOST - A6 (heavy).

The main components of the new crane:

  • span bridge - box girder of welded structure produced by Kyiv Crane Machinery Plant LLC;
  • lifting mechanism - crane truck (also manufactured at Kyiv Crane Machinery Plant LLC);
  • end beams - Podem (Bulgaria);
  • motor-reducers of movement and lifting - by Sew Eurodrive (Germany).

The speed of lifting and moving loads is regulated by means of frequency regulation of the respective drives. Electric cable and busbar supply systems to the crane - flexible electrical cable with carts on the cable. The crane package includes a pendant for remote control, there is also the possibility of radio control. Additional equipment includes: limit switches for hoist and crane movement (separately), load limiter, light and sound alarm.

At this time, a new grab bridge crane is successfully operated in a three-shift mode, with its help pellets are loaded around the clock into the boilers. Thus, the use of the new crane of the KZPTO crane allowed the TPP team to significantly increase its capacity and supply even more electricity, thereby contributing to the cause of ensuring the energy independence of our country.
