The first category is equipment with bar surface elasticity.

Such as horizontal bars and parallel bars; due to the fact that the operator has a higher ground clearance during fitness exercises, it has a certain degree of difficulty and danger, and the elastic deformation caused by repeated use for a long time is easy to cause fatigue cracks and fractures in the horizontal bars. On the basis of the safe service life of 1 year, since the implementation of the new national standard for outdoor fitness equipment on October 1, 2011, the safe service life of all cars is 8 years.

The second category is equipment with various movable parts such as rotating, swinging or sliding. Equipment such as strollers, swings, chair swings, seesaws, etc., due to the frequent wear and tear of various movable parts during use, refer to the normal service life of general machinery and equipment, and set it in an outdoor environment. Under the conditions of daily management, combined with the service life of outdoor fitness equipment in use, the safe service life of this type of equipment is determined to be 4 years.

The third category is other stable equipment without any movable parts. For example, fixed stakes, balance beams (actually steel parts), fixed ladders, climbing walls, sit-up beds, etc., due to the absence of wear, collisions, etc., the outdoor environment is also set at the basic Under the conditions of unmanned daily management, since October 1, 2011, the new national standard for outdoor fitness equipment has been implemented. The safe service life of all cars is 8 years.
