Periodic Control and Inspection of Bridge Cranes

Gantry cranes are essentially cranes installed between two beams placed high. Overhead cranes are used in factories, large constructions or industrial facilities where needed. These cranes can be operated from a fixed or mobile operator's cabin, from the ground or remotely. Bridge cranes can move back and forth on the bridge along the main axis, move the load back and forth, or lift and lower the load on the vertical axis. Accordingly, the lifting speed, lifting height, carrying speed and carrying capacity are important features in bridge cranes. When constructing a gantry crane, calculations are made by taking these features and the operation of the enterprise into consideration. Especially when the weight is at the end parts, the bridge crane should not create a danger for human health and property safety.

In addition to this, bridged cranes belong to the group of lifting and conveying machines and in accordance with the Regulation on Health and Safety in the Use of Work Equipment published by the Ministry of Labor and Social Security, the construction machinery and equipment used in the enterprises must meet the minimum requirements for health and safety. Accordingly, if no other conditions are required in the relevant standards, the testing of bridge cranes is carried out with the 1,25 multiplied of the declared load.

Some of the bridge cranes are double girder gantry cranes. They move on crane tracks and have a higher lifting force than bridge cranes with single girders. However, bridge cranes of any type must have load-resistant load brakes. Furthermore, these cranes must be inspected and inspected at least once a year by mechanical engineers, machine technicians or high technicians.

Our company carries out periodic controls and inspections of bridge cranes within the scope of periodic controls of hoisting and conveying machines in compliance with current legal regulations and standards published by domestic and foreign organizations. This A few standards based on the studies are:

 

  • TS 10116 Lifting and conveying machines - Cranes - Inspection and test methods
  • Steel wire ropes - Safety - Section 12385: Operation and maintenance information
  • TS ISO 4309 Cranes - Wire ropes - Application rules for inspection and decommissioning
  • TS ISO 12480-1 Cranes - Safe use - Section 1: General
