Yale YL LHG ATEX Low-Headroom Hand Chain Hoist with Integrated Geared Trolley

Model YL LHG ATEX | Capacity 500 kg to 2,000 kg | ATEX II 2 GD C IIC T4 | Zone 1 / Zone 21 | Ultra-Low Headroom | Hand-Geared Travel | Spark-Resistant

The Yale YL LHG ATEX combines all four specialist features in a single integrated assembly: the patented 360° rotating hand chain guide from the Yalelift 360 ATEX; the specially developed LH lateral chain reeving system for ultra-low closed headroom; hand-chain driven geared trolley travel for precise positioning; and full ATEX certification with bronze trolley wheels, copper-coated hooks, MKS micro corrosion protection, and rubber buffers as standard. The hand-geared mechanism holds the trolley position when the chain is released, eliminating creep risk in hazardous environments. The YL LHG ATEX covers capacities 500 kg, 1,000 kg, and 2,000 kg in Size A (60 to 180 mm beam flange) as standard; higher capacities and Size B are available on request.

Technical Specifications

Specifications quoted are for MEDIUM design at standard 3 m Height of Lift, Size A beam range. Higher capacities (3,000 kg and above) and Size B (180 to 300 mm beam flange) are available as special order. HIGH design (with stainless steel load chain) is supplied with reduced capacities.

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.
• Ultra-low closed headroom: LH lateral chain reeving pulls the bottom hook block almost against the beam flange.
• Hand-chain geared travel: Precise, controlled trolley positioning. Holds position when chain released, no creep on sloping beams.
• Patented 360° rotating hand chain guide: Operator can apply force from any angle.
• All four specialist features in one unit: ATEX certification + low headroom + geared travel + 360° rotating hand chain guide.

Suitable Applications

The YL LHG ATEX is the specification of choice where ATEX zones combine with low-headroom requirements and the need for precise positioning. Typical applications: refinery and chemical plant compact areas requiring exact load placement; pharmaceutical clean rooms with low ceilings; offshore module installation under low pipework; pharmaceutical and food production lines under existing gantries; and any sloping or curved beam application in a hazardous area.

How to Use the Yale YL LHG ATEX Low-Headroom Hand Chain Hoist with Integrated Geared Trolley

1. Verify the ATEX zone classification: Confirm the unit's ATEX marking matches the zone, gas group, and temperature class of the work area.
2. Verify beam compatibility: Confirm beam flange width and thickness are within the trolley's rated range.
3. Adjust the trolley side plates: Adjust to match the 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 features: Anti-drop, anti-tilt, rubber buffers, gear engagement, MKS coating, copper hook plating, bronze wheels all operational.
6. Engage the load: Use ATEX-rated lifting accessories.
7. Lift using the hoist hand chain: Apply steady pull. Hand chain pull varies with capacity.
8. Traverse using the trolley hand chain: Pull the trolley hand chain to drive along the beam in controlled increments.
9. Position precisely: Gear mechanism holds the trolley in position when the hand chain is released, no creep risk.

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.

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 matches the work area zone classification.
• Use only ATEX-rated lifting accessories.
• Visual inspection must include MKS coating, copper hook coating, bronze wheels, rubber buffers.
• Maintain the minimum clearance between hoist body and beam flange during operation.
• Damaged ATEX components must be assessed by a competent person.

Inspection and Maintenance

The YL LHG ATEX requires the same routine maintenance as the YL LHG, plus regular checks on ATEX-specific components. Use only ATEX-compatible lubricants. Damaged ATEX components must be assessed by a competent person. WOLFF Onsite provides full ATEX-compliant inspection, spare parts, and overhaul services.

Optional Accessories

• HIGH design upgrade: Stainless steel load chain. Supplied with reduced capacities.
• Adjustable overload protection device: ATEX-compatible slip-clutch overload limiter.
• ATEX chain container: Compatible chain container sized to match each capacity.
• Beam locking device: ATEX-compatible beam locking device.
• Size B beam range: 180 to 300 mm available on request.
• Higher capacities: 3,000 kg and above available as special order.
• Extended Height of Lift: Available on request.
