Which conditions must be avoided during a five year counterweight buffer test?

During a five-year counterweight buffer test, it is critical to maintain certain operational safety features to ensure the test is conducted safely and effectively. The proper functioning of direction control is essential because buffers are designed to stop or slow down the counterweight in specific operational contexts, including directional movement. If the direction controls are disabled, the testing conditions could lead to unpredictable results or unsafe situations, as the buffer may not function as intended when the counterweight approaches the end of its travel.

Maintaining the integrity of the directional control helps ensure that the buffer can react appropriately based on the counterweight's movement toward it. This is key to verifying that the buffer properly absorbs the energy of the moving counterweight and prevents potential accidents or damage. In sum, avoiding the disabling of directional controls is vital for ensuring the buffer can perform its intended safety function during the test.
