Here it depends especially on Express to determine work safety condition of the electrical system and all of the system resources. The maximum time limit for the periodic inspection is according to lift directive 95/16/EC two years. This period is on for people working elevators and Hoists with passenger transport. Elevators are an exception to the machinery directive 98/37/EC, here must be inspected every four years are. The recurring or even main test is similar to the test for the first time and includes the same test content. Midterm is once again on proper operation and safe condition to check after the test before initial use or the first recurring inspection, as well as between two main tests the lift system.

It is a so-called midterm. It includes essentially: test of the traction sheave for wear testing of hoist, as well as their attachment to proper condition testing of the emergency call system testing of the mechanical brake testing the car door, the landing doors and their closures and electrical safety devices primarily serves the midterm to to determine whether the lift system can be operated properly and safely. Tests according to There are countless ways to change the State of a lift system changes / significant changes. Examples of modifications and significant changes of lift installations are: put the complete lift system change the complete shaft modification or renewal of the shaft wall, tray ceiling, shaft soil increase or reduction in removing or closing of access installation of shaft ventilation system renewal establishing emergency renewal of the electrical security system change the nominal speed of the system change the guide rails change the thresholds change the weight of the car complete new car this is only a fraction of many other measures to amend, which is usually performed on elevator installations. A commissioning can take place only after such renewals, the reliable and proper condition with regard to mounting, installation and the installation conditions, the system has been determined.
