Max. user weight
The maximum weight that a horizontal bar or parallel bars can safely withstand. This parameter is one of the most important when choosing. It is impossible to exceed the weight recommended by the manufacturer: even if the structure does not break immediately, this can happen at any time, which is fraught with falls and serious injuries. In addition, we note that the maximum weight is also determined by the specifications of the mounts, and under abnormal loads, they may also not withstand.
Accordingly, it is worth choosing according to this parameter, based on the weight of the heaviest person who intends to use the device. If the design is purchased for use by a limited circle of people (for example, as a "home" horizontal bar for a family of 4-5 people), there are no problems with the choice. But if the device is designed for an unlimited number of people — for example, in a fitness club that people with different physiques can visit — it is desirable that the maximum weight be as large as possible. Otherwise, there is a high probability that the device will not work for a massive athlete.
Also, note that it is worth choosing according to the maximum weight with a margin — at least 10 – 15 kg. This is due not only to general recommendations on reliability, but also to very specific points: some athletes prefer to train with additional weights, and this weight will also load the horizontal bar or parallel bars.
Dimensions
The dimensions of the equipment in the assembled and ready-to-work state. It is important to note that more space is needed for the comfortable and proper usage of the device. This is due to the need to have space for the athlete himself, and the space for arms and legs when performing exercises and using additional equipment. If we are talking about a gym, then people training nearby or placed equipment, etc., can become an obstacle. Therefore, it is recommended when choosing to calculate that in addition to the dimensions of the device, you may need an additional metre of free space on each side.
