The Yale HTG ATEX is the explosion-protected geared trolley from Yale's manual trolley range, combining the mechanical advantage of hand-chain driven geared travel with full ATEX certification. The BASIC grade suits Zone 2/22 explosive atmospheres, with MKS spark-resistant coating on all external surfaces and a stainless steel hand chain fitted as standard. For the most demanding atmospheres (Zone 1/21), the HIGH grade is available with solid bronze wheels.
Key Features
- ATEX BASIC certification (Zone 2/22): II 3G Ex h IIA T4 Gc and II 3D Ex h IIIA T135 °C Dc.
- Hand-chain geared drive: Lower operator effort than push variants for ATEX zone moves.
- MKS spark-resistant coating: Fully coated externals prevent friction ignition.
- Stainless steel hand chain as standard: Corrosion-resistant, low spark potential.
- Rubber buffers as standard: Reduce impact at end-of-travel.
- Standard HTG platform: Same machined steel wheels, encapsulated ball bearings, 14% incline rating.

More About This Product
The Yale HTG ATEX is the explosion-protected geared trolley from Yale's manual trolley range. Combining the mechanical advantage of hand-chain driven geared travel with full ATEX certification, the HTG ATEX BASIC is suitable for Zone 2/22 explosive atmospheres. The MKS spark-resistant coating is applied to all external surfaces, and the HTG ATEX comes fitted with a stainless steel hand chain as standard. For the most demanding atmospheres (Zone 1/21), the HIGH grade is available with solid bronze wheels.
Suitable Applications
For explosion-protected heavy lifting and traverse: chemical and petrochemical refineries, paint and coatings plants, pharmaceutical production with solvents, fuel terminals, mining, grain elevators, dust-handling facilities, shipyards with flammable cargo. Whenever a manual geared trolley needs to move a load through an explosive atmosphere.
How to Use the Yale HTG ATEX
- Confirm zone: BASIC for Zone 2/22, HIGH for Zone 1/21.
- Inspect MKS coating and hand chain: Visual check before each use.
- Confirm beam compatibility.
- Attach ATEX hoist: Matching zone and grade.
- Travel using stainless steel hand chain: Steady pull — avoid sudden jerks.
Warning: All lifting components must be ATEX-rated to the same zone. Mixing rated and unrated equipment defeats protection.
Safety Information
- Verify ATEX zone classification before installation.
- Inspect MKS coating and hand chain before each use.
- Use only with ATEX-compliant lifting equipment.
- Never exceed the Working Load Limit.
- Install beam end stops at both ends.
- Never lift, lower or transport persons.
- Use manufacturer's hand chain only — no mechanical drives.
- LOLER 1998 thorough examination every 12 months.
Inspection and Maintenance
Combines standard HTG maintenance with ATEX-specific inspection of MKS coating and stainless steel hand chain. Coating damage compromises certification and must be repaired before further use. WOLFF Onsite provides LOLER and ATEX-aware inspection.
Optional Accessories
- HIGH grade ATEX upgrade: Zone 1/21 with solid bronze wheels.
- Higher capacity ATEX: 8,000 / 10,000 / 20,000 kg variants available on request.
- Locking device & rotating hand-chain guide: Available options.

Frequently Asked Questions
Q: HTG ATEX BASIC or HIGH — which do I need?
BASIC covers Zone 2/22 — atmospheres unlikely during normal operation. HIGH covers Zone 1/21 — atmospheres likely during normal operation. HIGH uses solid bronze wheels and a wider gas group certification (IIC vs IIA). Your DSEAR/ATEX zoning assessment determines which zone applies.
Q: Why stainless steel hand chain for ATEX?
Stainless steel resists corrosion in the wet, humid or chemically aggressive environments common to ATEX facilities, and its surface characteristics reduce spark potential from chain-on-chain rubbing. Fitted as standard on HTG ATEX at no extra cost.
Q: Are higher capacity HTG ATEX models available?
Yes — 8,000 kg (N05300111), 10,000 kg (N05300112) and 20,000 kg (N05300114) ATEX BASIC variants, plus equivalent HIGH grade SKUs. Not in standard stock but available on order. Contact us for lead times.
Q: Can I use a non-ATEX chain hoist with the HTG ATEX?
No. The full lifting assembly must be ATEX-rated. Pair the HTG ATEX with EX09 (Yale C/D 85 ATEX) or EX08 (Yale UNOplus ATEX) hoists for a compliant assembly.
