Product Description
Stretch the hip joints and relax the muscles of the lower back; develop upper-body support strength and core stability.
[Main Technical Parameters]:
◆ Directly buried type: the main upright posts are made of standard rectangular tubing measuring 100 mm × 100 mm with a wall thickness of no less than 3 mm; both sides of the posts are equipped with… Use aluminum alloy profiles with a wall thickness exceeding 2 mm, and incorporate plug‑in plastic‑wood profiles on both sides, each with a wall thickness greater than 5 mm. The overall external dimensions of the column shall be no less than 128 mm × 128 mm.
◆ The armrest curved tube of the back-stretching device is made from national-standard steel tubing with a diameter of 42 mm and a wall thickness of 2.5 mm.
◆ The main frame support tubes are made of 40×80×2 mm square tubing, while the secondary support tubes use 20×30×2 mm square tubing; the thickness of the mounting base plate is… The diameter is 6 mm to prevent the user from getting snagged or injured.
◆ The equipment panel is fabricated from 2.2‑mm‑thick cold‑rolled steel sheet, with both sides fully enclosed by 3‑mm‑thick cold‑rolled steel to prevent injury from clamps.
◆ The equipment nameplate is made of fully stainless steel with a corrosion-resistant finish, incorporates a QR code and the NSCC logo, measures 220×80 mm, and has a wall thickness of… 0.45 mm; the rivets are robust, and the edges fit tightly against the uprights to prevent snagging and injury.
◆ The equipment has undergone relevant static load, stability, impact, and fatigue tests in accordance with the GB 19272-2011 standard and complies with… Standard requirements.
◆ The entire machine has no snagging, no crushing points, no shearing points, and no pinching or clamping areas; all apertures and gaps comply with… GB19272-2011 Standard;
◆ The equipment features a one‑stop exercise station, allowing a single user to operate it simultaneously.
◆ The embedding depth of the equipment upright shall be no less than 500 mm, and the underground dimensions shall be no less than 500 × 500 × 600 mm.
◆ The materials are cut using a fully automatic CNC sawing machine, ensuring high efficiency and precise positioning. The pipe-bending process employs a CNC pipe bender, with angles… Accurate dimensions and aesthetically pleasing appearance; prior to welding, the components undergo degreasing to ensure that no oil or contaminants remain on the workpiece surface. Welding… Using a CO₂ shielded welding machine with a mixed gas, the welds exhibit an aesthetically pleasing appearance and straight, smooth bead profiles, eliminating the need for grinding. It is also equipped with a dust collection and treatment system to purify the workshop air, ensuring workers’ health. Surface treatment is carried out using blasting. Round‑grit finishing ensures thorough rust removal, increases the workpiece’s surface area, and enhances the adhesion of the powder coating. Outer surface: Forbidden City green ring Anti-static powder coating, applied using imported electrostatic spraying equipment, delivers uniform powder distribution and strong adhesion; the coated surface is resistant to acids and alkalis. It is resistant to damp heat, aging, and corrosion, with an attractive appearance, making it suitable for humid and acid‑rain environments; the product’s coating formulation does not… It contains toxic elements; powder recovery employs a cyclone‑type centrifugal separator, achieving a recovery rate of up to 98.6% and resulting in savings. The powder reduces dust pollution, is easy to handle, and is energy-efficient and environmentally friendly.
◆ The equipment is packaged in a double-layer system: an inner layer of thickened bubble wrap and an outer layer secured with strapping, effectively protecting it during transit. Avoid collisions during handling to ensure the equipment remains undamaged.
