ATEX

Red Rooster Lifting air hoists, trolleys, crane kits, wire rope hoists, controls, festoon systems and manual hoist are all suitable for use in explosive atmospheres and conform with the ATEX directive 2014/34/EU for non-electrical equipment. Our equipment is CE and Ex marked confirming the ATEX rating for use in Europe and also accepted in many other parts of the world.

Where hoists are required to work in a potentially explosive atmosphere EN1127-1:2011 specifies the method for the identification of hazardous situations that may lead to an explosion. It also details the design and construction control measures to achieve the required rating. The ignition hazard assessment for our equipment is in accordance with the requirement of BS EN 80079-36:2016 and constructional safety requirement according to BS EN 80079-37:2016 which control’s the potential sources of ignition from the hoist.

Red Rooster Lifting supply industrial lifting equipment ranging from a SWL of 250 KG to 50 Tonne and can be certified for Equipment Group II, classification Category 2 & 3, namely Zones 1 & 2 in areas where flammable ‘Gases’ may be present such as solvent vapours, gases from fuels, gases from deposits, heating gases, cleaning fluids, solvents and fuels from broken pipes or fittings. For atmospheres with ‘Combustible Dust’ our equipment can be certified for use in Zones 21 & 22.

As standard all Red Rooster hoists are certified for Zone 2 (Gas) and Zone 22 (Dust). This excludes the TMM-140.

• Ex Group II 3 GD Ex h IIA (T4) 135°C

The majority of Red Rooster ATEX hoists can be certified for Zone 1 (Gas) and Zone 21 (Dust). This excludes the TMM-140.

• Ex Group II 2 GD Ex h (IIB or IIC) (T4) 135°C

Air hoists suitable for mining are certified – Group I Mining (I M2)

Ambient temperature range for air hoists is -20°C to +70°C
Ambient temperature range for air trolleys is -20°C to +60°C

Red Rooster equipment will be marked with the company details, serial number, model number, date, the Ex symbol, equipment group, category, gas group, and temperature.

All Red Rooster equipment is rated to Temperature class (T4) 135°C but can be rated to T5 or T6 depending on the area and gas / dust types and conditions by a special risk assessment. The gas group rating will be specified on the label and certification (IIA, IIB or IIC) so hoists should only be used in the areas there rating covers.

The TMH, TCR and TNC range of hoists are all manufactured from a Ductile Iron housing, are heavy duty hoists and highly robust so suited to working in a tough environment with rough handling and changing conditions. As Standard these hoists are certified as suitable for use in a Zone 2 area. Sources of ignition do not become active during normal operation even in severe operating conditions.

Several models of Red Rooster hoists can also be classified to BS EN 1127-2:2014 for equipment being used in mining. These hoists can be used according to Equipment Group I Category M 2 where equipment is intended to be de-energised in the event of an explosive atmosphere. The low operating temperatures along with the internal operating pressure of 4 - 6 Bar means that these hoists have a high level of protection and can also be disconnected or made safe, in the event of an explosive atmosphere. ATEX designation - Ex I M2.

The areas where dust deposits can build up are limited on air hoists body due to the shape of the air motor and gearbox. The TMH model has a very low running temperature so even with a build up over the motor the surface temperature does not reach close to 150°C. Other models such as TCR and TNC hoists do not reach the maximum permissible temperature of 150 ° C for coal dust.

When specifying equipment for use in an explosive atmosphere the end user should give a full specification confirming the – Equipment group, Category, Explosive Atmosphere, and Temperature class. If this is not supplied the working area conditions, details of the gas, how often gas is present, details of the dust and ambient temperature should be supplied. This allows the Explosive Protection Level (EPL) to be confirmed when the ignition sources are identified. Where we do not have all the required information we will specify the ATEX rating of the equipment offered.

The ATEX technical file covering our range of equipment we manufacture is filed with Lloyds Register – Lodgement number COV0912421/1.

Red Rooster Lifting hoists are heavy duty machines used around the world and are suitable for use in explosive atmospheres. They are used extensively in the shipbuilding, mining, offshore, onshore, petrochemical, chemical, pharmaceutical industries and other potentially hazardous areas.
