High and low bars
High and low bars
[Model] : GYX-M13B-1
[Specification] : 2820×130×2131 (including guardrail: 4882×4600×2131) (mm)
[Instructions for Use] : The practitioner grips the horizontal bar with a pronated or supinated grip (the user should hold the bar firmly with both hands to prevent falling), with hands shoulder-width apart, and hangs with straight arms. After pausing, simultaneously pull the body up using both arms (without any additional movements such as twisting or swinging), bending the elbows to perform a chin-up, then repeat the exercise.
[Main Features]: It strengthens the muscles of the upper limb girdle, the shoulder and back region, the chest, and the lumbar area, with particular emphasis on the latissimus dorsi and biceps. It also enhances grip strength and finger muscle power, while improving overall coordination and flexibility in whole-body movements.

Product Description
[Main Technical Parameters]:
◆ Direct‑buried design: The main upright posts are fabricated from standard rectangular galvanized steel tubing measuring 80 mm × 120 mm with a wall thickness of no less than 3 mm. On both sides of the posts, plug‑in aluminum alloy profiles are paired with wood‑plastic composite profiles. The overall external dimensions of each post shall be no smaller than 120 mm × 120 mm.
◆ The column tops are enclosed with 130 mm × 130 mm steel plates, 6 mm thick, to prevent rainwater ingress. The perimeter features R3 chamfers. Horizontal members are made of GB‑standard steel tubes with a diameter of 32 mm and a wall thickness of 4.5 mm; they are connected to the columns via a push‑in joint, with M10 bolts at the ends for secure fastening and anti‑loosening flat washers.
◆ The buffer layer is 300 mm thick, enhancing safety and reliability and helping to prevent accidental injuries.
◆ The equipment support post shall be embedded to a depth of no less than 600 mm, with a cushioning layer of 300 mm; the underground installation dimensions shall be no smaller than 400 × 500 × 600 mm.
◆ The equipment nameplate is made entirely of stainless steel, secured with rivets, and its edges are tightly fitted against the upright posts to prevent snagging, scratching, and other potential damage.
◆ The entire machine has no snagging, crushing points, shearing points, or pinching hazards; all apertures and gaps comply with GB 19272-2024. Standard;
◆ The equipment features a two‑station exercise configuration, allowing only two users at a time.
◆ The equipment has undergone relevant static load stability tests in accordance with the GB 19272-2024 standard and meets the standard’s requirements.
◆ The components are cut using a laser cutting 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 grease remains on the workpiece surface. Welding… Welding is performed using a CO₂ shielded arc welding machine with a mixed gas, resulting in aesthetically pleasing welds and straight, smooth weld beads that require no post-weld 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‑edge finishing ensures thorough rust removal and enhances the adhesion of the plastic powder. The electrostatic spraying process employs a two‑coat application: first, an epoxy zinc‑rich primer is applied, The exterior surface is coated with a green, antistatic powder. Utilizing imported electrostatic spraying equipment, the coating delivers uniform powder distribution and strong adhesion. The finished surface exhibits excellent resistance to acids and alkalis, withstands humid‑heat conditions, resists aging, and maintains an aesthetically pleasing appearance—making it ideal for humid environments and areas prone to acid rain. The coating formulation contains no toxic elements, and a cyclone‑type centrifugal powder recovery system ensures a recovery rate of up to 98.6%, reducing material waste and minimizing dust pollution while offering convenient operation and energy‑efficient, environmentally friendly performance.
◆ The equipment is packaged in a double-layer system, effectively preventing impacts and scratches during transit, ensuring the equipment remains undamaged.
