In order to perform lifting machines metal structures manufacturing, installation, repair, and reconstruction it is necessary to check the equipment and materials using non-destructive and destructive methods.

For this purpose “Laboratory of non-destructive inspection and diagnostics” (Certificate No. 61A290444 dated 19.05.2006) and “Mechanical tests laboratory” (Certificate No. 98 dated 26.04.2006) were organized. Using the devices of non-destructive testing and also pull test machines, pendulum impact machine, hardness devices and applying various ways of measuring, the following types of work may be done:

Destructive checking:

• Determination of metal-roll physics-mechanical characteristics of fastening articles for compliance with Quality Certificate (determination of hardness, strength limit, impact viscosity, plasticity

Welding seams and main metal non destructive inspection:

• Lifting constructions:
  
  • Lifting cranes
  • Elevators
  • Lifts
  • Cranes-manipulators
  • Crane tracks
• Gas supply system (gas distribution):
  
  • Outer gas pipe lines
  • Outer steel gas pipe lines
  • Articles and units, gas equipment

Types (methods) of non-destructive checking and diagnostics:

• Acoustic type of checking:
  
  • Ultrasonic defectoscopy
  • Ultrasonic thickness measuring
• By penetrating substances:
  
  • Capillary testing
  • Visual inspection and measuring
