SECTION 1CROSS HAULING WITHRED ROOSTER HOISTSLike all air hoists, the RED ROOSTER hoist range is designedfor vertical lifting. Under special circumstances, cross haulingcan be achieved with single or two-fall hoist models, up toan angle of 20 degrees from the vertical, with 25 degrees onsome capacities under specific conditions.It is imperative that special precautions are in place for crosshauling applications - a lift plan, method statement and arisk assessment should be completed by a qualified person.A site assessment should be carried out, checking thestructure from which the hoists will be suspended, the hoistlocations (route of travel), operator position and also theshape size and weight of the item to be cross hauled.Site conditions should always be taken into account asdifferent problems will be encountered at each site.We recommend tag lines to be attached to the hoists andwherever possible, lower the load down to the next hoistat an angle letting it take the load, then raise at a muchreduced angle.For all cross hauling applications, please contact ourspecialists to confirm the suitability of our hoists forthe application.SECTION 1MARINE AND CORROSIVE PROTECTIONPAINT SYSTEMSWe have established paint application systems to control thepainting of our equipment based on ISO 12944.Our systems can also be used for several parts of NORSOKM501.

SECTION 3SECTION 3ATEXThe RED ROOSTER Spark Resistant Air chain Hoists are verysuitable to be used in explosion dangerous areas becauseair does not generate sparks (on the contrary to electricity).RED ROOSTER Spark Resistant Air chain Hoists are veryeconomical, and supplied at very competitive prices.In various industries like (petro) chemical industry, oil/gasindustry, offshore, power plants, mining, food industry andmany other industries an explosion dangerous atmospherecan arise during processing, transporting or storing, due togas, vapor or dust.Explosive atmospheres can be caused by flammable gases,mists or vapours, or by combustible dusts. If there is enoughof a substance mixed with air then all it needs is a sourceof ignition to cause an explosion. Preventing release ofdangerous substances and controlling potential sources ofignition are two widely used ways of reducing risk.Why do we need ATEX certification If you manufacture a product that is to be used in apotentially explosive environment and you want tosell in the European Union, then you will need toapply the CE and Ex mark on it. The ATEX 94/9/EC Directive (ATEX 95) covers bothelectrical and mechanical equipment which is splitinto two categories of equipment, Group I mining &Group II above ground. Our lodgement is for mechanical non electricalequipment which are capable of causing their ownsource of ignition.All standard RED ROOSTER pneumatic hoists and trolleys from250 kg to 100 tonne can be certified for use in II 3 GD c IIA T4 1)area and with additional protection built into the hoistthey can be certified for II 2 GD c IIB T4 1) & II 2 GD c IIC T4 2)area. The preparation work required to be carried out onour hoists varies on the protection level requested by thecustomer. With the information on where the hoist will beoperating we prepare the hoist to be suitable for the zone,gas group and temperature rating.Our lodgement COV0912421/1 filed with Lloyds Registercovers the range of ATEX units we manufacture.The TCR, TNC, TMH & TCS ranges of hoists are heavy duty unitswith a wide range of uses in a variety of industries all over theworld. The ATEX range of hoists are built to stand up to differentenvironments making them safe to use in explosive atmospheres.Depending on the classification we can bronze spray hooks, fitstainless steel safety latches, use either zinc plated or stainlesssteel load chain and fit stainless steel chain collectors.12WWW.RAMI-YOKOTA.COMATEX DIRECTIVERED ROOSTER pneumatic trolleys, geared trolleys and pushtrolleys are fitted with bronze wheels, bronze anti-tip rollers,rubber buffers and air trolleys have ATEX rated air motors,gearboxes and valves. Our trolleys are suitable for a range ofbeam sizes and profiles, with rack and pinion, beam brake,low headroom and ultra low headroom units available inmost capacities.We also do a range of ATEX pneumatic wire rope hoists builtto suit customer requirements. These hoist units have beenfully converted to air powered units from ATEX certified partscovered by our risk assessment for the process and parts usedin manufacture.Our Spark Resistant Air chain Hoists are widely used ina.o. the On and Off-shore, (petro) chemical industry, paintspraying, chemical production and -storage, pharmaceuticalindustry and tank-cleaning.1)Formerly known as zone 2 & 222)Formerly known as zone 1 & 21Spark Resistant Air Chain HoistsBronze wheelsRubber bumpersAtmosphéres explosiblesATEX comes from the French words "ATmosphéresEXplosibles" which is the name commonly given tothe two European Directives for controlling explosiveatmospheres. The aim of the directive 94/9/EC is toallow free trade of ATEX equipment within the EU.Some other parts of the world do not have regulationson non electrical equipment in explosive areas andhave also adopted the ATEX directive.Hazardous areasGas atmospheres Directive 94/9/EC (ATEX 95) is for the manufacturersof equipment used in explosive atmospheres. Directive 99/92/EC (ATEX 137) is for the health andsafety protection of workers and manufacturers ofinstallations within a potentially explosiveatmosphere.Dust atmosphereThe Directive 99/92/EC applies to most workplaceswhere an explosion may occur, so employers must carryout risk assessments to classify different groups toensure that the correct equipment can be selected forthat specific area. These risk assessments should be kepton file and the classification for that area passed on tomanufacturers or suppliers when selecting the correctequipment. This equipment should be of the same orhigher classification.ZONE 22 AREA OUTSIDEZONE 21 (DUST DEPOSITS)ZONE 21(1 MTR.
