Yale UNOplus-A ATEX Ratchet Lever Hoist

Model UNOplus-A | Ratchet Lever Hoist | Basic / Mining ATEX | 750–6000 kg | 1.5 m Lift

The Yale UNOplus-A ATEX is the further-developed Series A ratchet lever hoist, certified to ATEX Directive 2014/34/EU under Basic and Basic Mining classifications. The versatile tool for lifting, pulling and securing loads delivers compact, robust performance from 750 kg to 6000 kg with a 1.5 m standard lift. Optimised gearing and improved bearings reduce operator effort, while the standard free-chaining device allows fast load attachment and chain pull-through in both directions.

Key Features

• ATEX Basic and Mining certified — Suitable for surface Zone 1/21 and underground mining environments.
• Optimised low-effort operation — Improved gearing and bearings — minimum lever pull from 22 daN at 750 kg.
• Free-chaining device — Standard feature for fast load attachment and chain pull-through in both directions.
• Compact, robust stamped steel construction — Reduced weight optimises portability and operator comfort.
• Automatic screw-and-disc load brake — Corrosion-protected components for long service life.
• Robust chain guide rollers — Eliminate fouling and jamming of chain on the load sheave.
• Short hand lever — Compact design for use in restricted access locations.

Technical Specifications

Standard lift 1.5 m on all variants — non-standard lifts available on request. The 1500 kg variant carries 1 unit in stock with a 3-day lead time.

Suitable Applications

Maintenance lifting, securing of loads, pulling and tensioning operations in chemical, offshore, refinery and underground mining environments. Particularly suited to confined-space and remote-location work where a hand-portable lifting device is required in a hazardous area.

How to Use the UNOplus-A ATEX

1. Inspect the hoist before each use — check the chain, hooks, safety latches and the ratchet lever.
2. Confirm the rated capacity on the hoist body exceeds the load weight.
3. Attach the top hook to a verified anchor point above the load.
4. Engage the free-chaining device and pull the chain through to position the bottom hook.
5. Disengage the free-chaining device and attach the bottom hook to the load.
6. Operate the hand lever in short, smooth strokes to lift, lower or tension the load.

Warning:
Confirm the ATEX zone classification of the work area matches the hoist certification before use. Do not extend the hand lever or fit a cheater bar — the rated pull force is calculated for the supplied lever length only.

Safety Information

• Confirm the ATEX zone classification of the work area matches the equipment certification before use.
• Never exceed the rated working load limit displayed on the equipment.
• Never use equipment that shows visible damage, wear or deformation.
• Keep all personnel clear of the lifted load at all times.
• Do not modify, repair or substitute components other than as specified by the manufacturer.
• Ensure the operator is trained, competent and authorised for ATEX lifting operations.

Inspection and Maintenance

Inspect before each use — focus on all load-bearing components, welds, hooks, safety latches, chain, rope and pendant controls. Thorough examination under LOLER 1998 is required at intervals not exceeding 6 months by a competent person. Replacement parts must be genuine manufacturer items to maintain certification. Records of all inspections must be retained for the life of the equipment.
