Most of the equipment used in workplaces, especially in heavy industry, should be checked regularly. Wear and malfunctions that may occur due to the working system of the equipment can cause problems that can harm employees. For this reason, according to the occupational health and safety law, employers regularly check and test the equipment used to protect employees. 

Periodic control is the maintenance of a material or equipment so that it can operate longer. In periodic controls, depending on the working conditions of the equipment, the worn parts of the equipment are maintained and replaced if they need to be replaced. In these controls carried out in certain periods, certain tests are carried out at the same time to see the operating status of the equipment.

The parts in many equipment have a certain lifespan. Depending on the use, these parts do not work at the standards they should work after a while. With the deterioration of this working standard, there may be problems in the materials produced due to the use of the equipment and there may be danger for the employees using that machine or equipment. 

Periodic controls and tests are the controls of machinery and equipment within certain periods. In these controls, if there are parts of the equipment that need to be replaced in due time, they are identified and replaced. In addition, during these controls, the necessary tests of the equipment are carried out and if there is a problem, it ensures that they are solved. These tests aim to make the equipment safer for both employers and employees. 

Periodic tests and controls are carried out to ensure that the equipment operates in a healthy and safe manner. Thanks to these processes, the machines work more efficiently, which results in better quality work and processes for employers and increased earnings. The biggest advantage of periodic checks and tests is the prevention of work accidents that may occur due to equipment. 

When the statistics on occupational accidents are analyzed, it is seen that many occupational accidents are caused by equipment that is not subjected to the necessary controls and tests. Regular periodic checks and tests contribute greatly to the prevention of equipment-related occupational accidents. In addition, thanks to the controls carried out, it creates positive results for employers in terms of earnings, as the equipment will operate in a healthier way. 

The controls and tests of the equipment used to assist employees in the transportation and placement of heavy loads in workplaces are very important. Within the scope of lifting equipment, periodic controls and tests of equipment such as lift systems, forklift vehicles, roller lever systems, hoist systems, trifor periodic maintenance, pallet trucks, cranes, mobile cranes and tower cranes are carried out. 

In the periodic controls, a periodic control inspection form is issued by experts related to the equipment. If any defect is detected as a result of the controls, it is indicated in the forum. If the deficiencies detected are eliminated, re-checks and tests are carried out and a conformity report is issued.
