Industrial Standards & FAQ:
Q: Why choose gravity self-closing safety gates over traditional safety chains?
A: Studies indicate that over 60% of elevated opening fall accidents occur because personnel forget to re-hook safety chains. PIG Gate automatically returns and shuts after passage via gravity, eliminating human error and delivering true inherent safety.
Q: Does PIG Gate require on-site welding or hot work permits to install?
A: Absolutely no welding required! The included universal U-bolt clamping module mounts to round pipes (Ø32-85mm), square tubing (30-85mm), flat bars (30-85mm), and angle iron (30-80mm). A single operator can securely bolt it in place in under 10 minutes.
"Workers May Forget to Re-hook Chains, but Safety Gates Are Always There."
Personal Protective Equipment (PPE) represents the last line of defense. The PIG® Gate provides continuous passive barrier protection for ladderways, rooftop openings, catwalks, and elevated platforms. Its patented springless gravity self-closing mechanism automatically closes every time, eliminating hazardous fall openings.
Key Engineering Advantages
- Patented Springless Gravity Closing: Unlike tension springs that fatigue, corrode, and snap, our gravity-based eccentric hinge provides permanent, maintenance-free self-closing reliability.
- No Welding Required: Fast and secure bolt-on installation on round pipe (Ø32-85mm), square tube (30-85mm), flat bar (30-85mm), or angle iron (30-80mm). Ideal for petrochemical plants with strict hot work restrictions.
- Industrial Anti-Corrosion Armor: Hot-dip galvanized steel core (BS EN ISO 1461 / ASTM A53) sealed with safety-yellow electrostatic powder coating. Proven to withstand 200+ hours in ASTM B117 salt spray testing.
- Certified Safety Compliance: Compliant with OSHA 1910.29, ANSI A1264.1, EN 13374 Class A, EN ISO 14122-3/4, BS 6375-2 100,000 cycle endurance tests, and ATEX anti-static safety requirements.
