The functions of the plastic wood handlebar three-person waist trainer and the issues that should be paid attention to. The installation of the three-handlebar waist trainer: 1. The ground installation of the equipment and its buried structure should meet the following requirements (with a large ground surface). (Except for equipment with frame bases), equipment columns buried underground should be reliably fixed to the lateral support or support plate, and the soil quality for installing the equipment should be Class II general hard soil with a fastening coefficient not less than . and above non-porous and non-sandy loam geological structures. Otherwise, the soil should be treated equivalently before equipment can be installed
Note: For Class II general hard soil with a fastening coefficient not less than., a shovel can be used Determined by how difficult it is to excavate with force and a small amount of pickaxe. Soil that requires forceful excavation with a shovel and a small amount of excavation with a pickaxe can be regarded as Class II general hard soil with a fastening coefficient not less than It should be no less than the height of the equipment above the ground. There should be a concrete support layer of no less than the thickness below the bottom of the equipment column
. Concrete foundation pits for each supporting column of the equipment should be installed. The horizontal size should not be less than Rock climbers, children's leisure swing chairs, four-position leisure swing chairs, two-position leisure swing chairs, children's swings, upper limb tractors, horizontal bars, parallel bars, swings, swing chairs, ladders, ribs, space walkers, fitness riding machines, running machine, elliptical walking machine, outdoor rehabilitation equipment
