What are the specifications and models of safety harnesses for working at heights?

Safety harnesses for working at heights include the following models: DW1Y—Electrician's waist belt type for pole work, DW1F—Electrician's anti-slip type for pole work, T1W2Y—General Type I waist belt type with rope for pole work, etc. Safety harnesses for working at heights: Safety harnesses for working at heights, also known as full-body harnesses, are generally made of polypropylene and polyester webbing. Full-body harnesses are protective equipment designed to prevent falls and injuries for workers operating at heights. They consist of straps, ropes, shock-absorbing packs, and metal fittings, collectively referred to as full-body harnesses. Components of safety harnesses for working at heights: A safety rope is the rope (belt, wire rope) in the harness that connects the lanyard to the anchor point. Safety ropes generally serve to expand or limit the wearer's range of movement and absorb impact energy. A shock absorber is a component connected between the lanyard and the anchor point that absorbs part of the impact energy and reduces the force of impact during a fall. A self-retracting lifeline is a device installed at the anchor point, equipped with an extendable rope (belt, wire rope), connected between the lanyard and the anchor point, which triggers a braking action due to speed changes during a fall. A self-locking device is a component attached to a guide rail that triggers a braking action due to a fall. This component may not necessarily have shock-absorbing capabilities. A lanyard is the component that supports and controls the body, disperses impact forces, and prevents injuries during a fall. Lanyards consist of webbing, buckles, and other metal fittings, and generally include full-body lanyards, single waist lanyards, and half-body lanyards.
I've worked at heights for many years, and safety harness specifications and models are crucial. We mainly use full-body harnesses that comply with the national standard GB 6095-2021. The models vary by manufacturer, such as Sichuan Gold's G201 series or 3M DBI-SALA products. It must have a dorsal D-ring for lanyard attachment, leg straps, and a chest strap to distribute fall impact forces. When selecting, consider the work environment: construction sites often use Class A fall arrest, while power maintenance may opt for lighter models. Before each job, I check the label to confirm the model matches, and replace any worn or old harnesses immediately. Safety is no joke—using the wrong specifications can lead to failure, so always pair it with certified anchor points and lanyards. I've seen accidents where people used cheap, non-compliant waist belts—full-body harnesses are much safer.
