Service maintenance

Dvesta setup and programming department specialists provide service maintenance for cranes and crane equipment.

The periodic service maintenance includes:

  • complete functional  testing of all crane assemblies and functions
  • adjustment of crane control system parameters in line with the requirements of the operating personnel in order to optimize the performance of operating modes
  • analysis of the alarm message archives and implementation of measures to eliminate the underlying reasons
  • routine cleaning and inspection of electric equipment.

The recommended frequency of the recurrent service maintenance – quarterly.

The service maintenance of cranes also implies unplanned emergency calls of drive setup and PLC-programming specialists to analyze and restore the operation of the crane electric equipment.

Remote diagnostics and programming

In order to minimize the expenses on emergency calls of the maintenance crews, we suggest equipping your crane control systems with special remote diagnostics sub-systems. These systems can provide Dvesta setup and programming specialists with quick access to PLC and frequency converter software for remote detection of the most of possible system failures and the ways to resolve them.
