Yale YL ITG ATEX Hand Chain Hoist with Integrated Geared Trolley

Model YL ITG ATEX | Capacity 500 kg to 20,000 kg | ATEX II 2 GD C IIC T4 | Zone 1 / Zone 21 | Hand-Geared Travel | Spark-Resistant Bronze Wheels

The Yale YL ITG ATEX is the explosion-protected variant of the YL ITG geared-travel trolley, certified for use in Zone 1 (gas) and Zone 21 (dust) atmospheres under EU Directive 2014/34/EU. Built on the proven YL ITG chassis, the ATEX version adds solid bronze trolley wheels, copper-coated suspension and load hooks (MEDIUM design), and the MKS micro corrosion protection system. The hand-geared mechanism holds the trolley in position when the hand chain is released, giving precise positioning control without the risk of trolley creep, an important safety feature in hazardous environments where unintended movement is unacceptable. The integrated hoist is the Yalelift 360 ATEX with its patented 360° rotating hand chain guide. The YL ITG ATEX covers capacities from 500 kg up to 20,000 kg, with Size A standard for lower capacities and Size B (180 to 310 mm beam flange) used at 5,000 kg and above.

Technical Specifications

Specifications quoted are for MEDIUM design at standard 3 m Height of Lift. Weights for 5,000 kg and above are available on request, given the bespoke nature of larger ATEX installations. HIGH design (with stainless steel load chain) is supplied with reduced capacities, contact us for specification. The 20,000 kg model requires two operators on the hoist hand chain.

Key Features

• ATEX II 2 GD C IIC T4 certified: Suitable for Zone 1 gas and Zone 21 dust atmospheres, gas group IIC, maximum surface temperature 135 °C.
• MKS micro corrosion protection system: Two-coat treatment combining Delta-Protekt® KL100 basecoat (zinc/aluminium flake cathodic protection) and Delta Seal® topcoat (chemical-resistant microcrystalline finish).
• Copper-coated suspension and load hooks (MEDIUM design): Soft copper coating prevents spark generation if hooks contact ferrous structures.
• Solid bronze trolley wheels (MEDIUM and HIGH design): Non-sparking bronze wheel construction for safe operation in explosive atmospheres.
• Stainless steel load chain (HIGH design): Optional upgrade for the most aggressive ATEX environments. HIGH design models supplied with reduced capacities.
• Rubber buffers as standard: ATEX trolleys include rubber buffers to control end-of-beam contact without spark generation.
• Compliant with EU Directives 2014/34/EU and 99/92/EC: Full ATEX compliance for European explosive atmosphere applications.
• Hand-chain geared travel: Precise, controlled trolley positioning along the beam, holds position when hand chain is released, eliminates creep risk in hazardous areas.
• Heavy capacity range up to 20,000 kg: Inherited from the standard YL ITG, with full ATEX certification across the range.
• Patented 360° rotating hand chain guide: Operator can apply force from any angle, keeping clear of the load path.
• Easily converted to YL LHG ATEX (low headroom geared): Field upgrade available for applications requiring even smaller closed headroom.

Suitable Applications

The Yalelift YL ITG ATEX is designed for the most demanding industrial applications in explosive atmospheres, where precise load positioning, hold-in-place capability, and explosion protection are all required. Typical environments include: offshore oil and gas platforms; refineries; chemical processing plants; pharmaceutical manufacturing; large-scale paint and coating facilities; biogas and waste treatment plants; and heavy industrial paint shops. The geared variant is preferred over the push variant for heavier loads and any application where the load may be left unattended on the beam.

How to Use the Yale YL ITG ATEX Hand Chain Hoist with Integrated Geared Trolley

1. Verify the ATEX zone classification: Confirm the trolley's ATEX marking matches the zone, gas group, and temperature class of the work area.
2. Verify beam compatibility: Confirm beam flange width, thickness, and curve radius are within the trolley's rated range. Note higher capacities require Size B (125 to 310 mm beam flange).
3. Adjust the trolley side plates: Adjust to match beam flange using adjusting nuts.
4. Fit the trolley to the beam: Open, position over the beam, close and tighten adjusting nuts to specified torque.
5. Verify all ATEX safety devices: Anti-drop bolts, anti-tilt devices, rubber buffers, and gear engagement must all be operational. Check coating integrity (MKS, copper hooks, bronze wheels).
6. Engage the load: Use ATEX-rated lifting accessories. Lift using the hoist hand chain.
7. Traverse using the trolley hand chain: Pull the trolley hand chain to drive the trolley along the beam in controlled increments.
8. Position precisely: The gear mechanism holds position when the hand chain is released, no creep risk.
9. Two-operator operation for 20-tonne: The YL ITG ATEX 20,000 kg requires two operators on the hoist hand chain at WLL.

Warning: Yale hoists and trolleys are not designed for passenger elevation applications and must not be used for this purpose. Never use the trolley in zones, gas groups, or temperature classes exceeding the ATEX marking. Never modify or recoat any component without manufacturer approval.

Safety Information

• Verify beam flange width and thickness are within the trolley's rated range before each use.
• Verify the supporting beam structure is rated for the combined hoist plus full WLL load.
• Confirm anti-drop bolts and anti-tilt devices are present and operational before lifting.
• Never exceed the Working Load Limit stamped on the hoist body.
• Beam end stops must be fitted at both ends of the travel range to prevent trolley runoff.
• Never side-pull or angle-pull the load at the suspension point.
• Keep all personnel clear of the load travel path.
• Ensure adequate headroom for the loaded hoist plus chain travel.
• Remove from service immediately if chain elongation exceeds the discard criteria in the Operating Instructions.
• LOLER 1998 thorough examination required every 12 months by a competent person.
• Verify ATEX marking against work area zone classification before each use.
• Use only ATEX-rated lifting accessories.
• The 20,000 kg model requires two operators on the hoist hand chain.
• Visual inspection must include MKS coating, copper hook coating, bronze wheels, and rubber buffer condition.
• Damaged ATEX components must be assessed, repair may require manufacturer authorisation.

Inspection and Maintenance

The YL ITG ATEX requires the same routine maintenance as the standard YL ITG, with additional attention to coating integrity and ATEX-specific components. Lubricate the load chain and trolley gearing regularly with ATEX-compatible lubricant. Visually inspect MKS coating, copper hook coating, bronze trolley wheels, and rubber buffers at each LOLER examination. Damaged components must be assessed by a competent person, repair may require manufacturer authorisation. WOLFF Onsite provides full ATEX-compliant inspection, spare parts, and overhaul services.

Optional Accessories

• HIGH design upgrade: Stainless steel load chain for the most aggressive ATEX environments. Supplied with reduced capacities.
• Adjustable overload protection device: ATEX-compatible slip-clutch overload limiter on the hoist.
• ATEX chain container: Compatible chain container sized to match each capacity.
• Beam locking device: ATEX-compatible beam locking device for ships and offshore.
• Size B beam range: 180 to 310 mm beam flange range available on request for capacities up to 3,000 kg.
• Extended Height of Lift: Greater HOL than 3 m standard available on request.
