künzelsau ghana turning one into three durban johannesburg a powerful crane on its travels in autumn 2015, the certified partner of stahl crane- systems, stahl cranes & hoists, based in johannesburg, south africa, received a special order: a two-beam bridge crane fitted with stahl cranesystems equipment was to be manufactured in johannesburg and then trans- ported by land and sea to ghana, more than 10,000 km away. as so often, a carefully conceived special option had to be developed in order to make this project possible. >>> mag a z ine 18 5
>>> the order from orsam oil and gas south africa (ortec) reached stahl cranes & hoists in october 2015. a two-beam bridge crane with a total lifting capacity of 75 tonnes was to be supplied to the general electric work in ghana. stahl cranesystems produced an as 7 wire rope hoist for it at its künzelsau plant, and an sh wire rope hoist as an auxiliary hoist. the crane components for the project such as the controls and drives were also delivered to johannesburg by stahl cranesystems. here, stahl cranes & hoists completed and assembled the two-beam bridge crane. but how could such a massive crane make the long journey from johannes- burg in the south to ghana in the western part of the continent? working with engineers from stahl cranesystems, the team at stahl cranes & hoists developed a unique, ingenious beam construction made up of three indi- vidual parts. in this way, after it had been successfully assembled in the plant in johannesburg, the crane was dismantled and packed into two containers around 12 m long. these were transported 600 km by land to africa’s largest container docks in durban. from there, the crane was shipped by sea to ghana, over 9,000 km away. to keep to the project’s tight schedule, the stahl cranes & hoists technical team, led by site quality manager theunis van schalkwyk, also travelled to ghana. the engineers were supported by the expert staff of orsam oil and gas, who were actively involved in the work until completion of the project on the site of the end customer, general electric. together, they re-assembled, installed and commissioned the crane. when carrying out the load testing, the team had to battle a few challenges. ghana has been in an energy crisis for four years, and the country even has problems with running water at times. water initially had to be delivered by tanker to fill the bigbags, but these could not achieve the necessary reliable water pressure. this meant that testing the smc and sle output devices was

new crane new opportunities 14 tonnes per magnet magnet cranes ensure rapid, safe work sequences that do not harm materials, and they are now essential items in the steel industry. the material, shape, size and weight of the load can vary considerably, and magnetic lifting beams to pick up the steel are therefore generally individual one-off construc- tions. the crane system needed is also not available from any catalogue: these are sophisticated special solutions that are only offered by experienced crane-building experts.

report from künzelsau chain hoist assembly interview with gerrit buck, product manager chain hoists what precisely is done here, mr buck? this is where we produce the series st chain hoists, including the st ex. explosion-proof chain hoists. the first step is assembling the gearbox – by the way, we make the individual parts for these ourselves. the entire assem- bly then goes onto the test stand. in the next step, the coupling is set. then we record the motor’s current values and document them. then it’s off to the wet varnishing shop next door. in parallel, our colleagues our working on the electrics – we call it switching. once everything is completely assembled, we pull in the chain and the chain hoist goes to dispatch. how flexible is chain hoist assembly? we are very flexible, and this is vital nowadays. on aver- age, we produce between 8,000 and 10,000 chain hoists a year. however, our team is very well organised, so that we can change over to two-shift operation if lots of orders come in and also work on saturdays if necessary. our record was 1,200 chain hoists in a month. what models and designs are there? we have seven models in the programme as standard – from the little, compact st 05 for loads up to 630 kg to the st 60 with a lifting capacity of 6,300 kg. with our modular system, we can combine the subassemblies without any problem and are thus able to offer customised solu- tions. there are all sorts of variants based on the standard models, such as the std double chain hoist and the stb bigbag solution. for confined spaces, we offer the short headroom trolley and the extra short headroom trolley. so if we talk about the largest complete range of chain hoists, we’re not exaggerating. why is the stahl cranesystems chain hoist so popular? almost no other chain hoist is as compact as our st. and that’s despite the robust design! with the st, the chain guide is made from ductile cast iron, and the drive nut is case-hardened steel – both very hard materials.

endless possibilities the st chain hoist the st chain hoist has been one of the most compact and robust chain hoists in the market since it’s launch in 1999. developed as the follow-up to the t series, the st introduced a range of inno- vations. the switch from the sliding rotor motor to the cylindrical rotor motor with electromagnetic disc brake made it possible to make use of tried and tested series motors of well-known manu- facturers. the chain drive and chain guide of the st are made from ductile cast iron and are there- fore particularly robust and hard-wearing. the st chain hoist is suspended from this solid basis. because of the solid design, the st has a long working life even in heavy-duty situations. the st chain hoist has been the benchmark for years as regards durability and reliability and is still one of the most compact chain hoists in the market. on the basis of the modular series assembly units, countless customised variants can be made from the st for almost all applications and industries. example: timber industry chain hoists of various designs are used in a sawmill in the netherlands with single-girder overhead cranes. two special cranes operate in the joinery of south german prefabricated house manufacturer, despite the difficult conditions. compact standard st 20 chain hoists are used for lifting.
example: chemical industry in a chemical plant, an explosion- proof st 20 chain hoist with a lifting capacity of up to 1,600 kg is used for maintenance work in the open air. the narrow design of the explosion- proof chain hoist allows the entire width of the chain bridge to be used. in a metal-finishing plant, a special design with space-saving double chain hoists, type std 50, and specially developed, height-reduced crane end carriages lifts metal elements. example: automotive industry in each case, two st 20 chain hoists lift complete engine blocks and trans- port these through the assembly line. in each case, two st 50 chain hoists lift complete car bodies and transport these through the assembly line. example: systems building the bigbag version for loads of up to 3,200 kg lifts bigbag crossbars up to the highest hood position without annoying interfering edges. only 210 mm high: the extra short headroom trolley makes excellent use of the hook path in the low hall of a factory. in combination with the st 50 chain hoist for a lifting capacity of up to 5,000 kg. the 60 % reduction in overall height also increases the lift height. mag a z ine 18 mag a z in 18 15 15

pure fascination! hands-on crane technology usually, it’s not easy to explain how the handling of a crane system covering a whole building works. who has the chance to experience a crane system in action? stahl cranesystems wanted to make this experience possible for anyone who was interested, and so it built a fascinating model out of 7,500 lego bricks. lego has been captivating people for decades with its never-ending wealth of possibilities. from the brandenburg gate just ten centimetres high, through the building of the minster in ulm in miniature in the stuttgart swabia exhibition to the fantastic worlds in legoland, every structure can be built and any dream fulfilled with the little bricks. however, building real structures in lego is not easy and calls for a great deal of imagination and experience, and precise planning. this is why, for the construction of a miniature industrial building with mobile bridge crane, stahl cranesystems employed a certified lego model builder, who created a 100 x 75 cm large model. in addition to 7,500 lego bricks, the project required three motors, two infrared receives, two battery boxes and two infrared remote controls. the result was an exact replica of a real crane systems using stahl cranesystems technology on a scale of 1:40. as with a real crane system, the bridge crane can be moved in the building using a remote control. it can lift and load loads in the form of lego coils and, most importantly: it can be operated by anyone who is interested, irrespective of age and training. the model made its grand début at the hohenloher wirtschaftsmesse from 23–25 september 2016 in künzelsau and was an immediate hit. the good weather attracted crowds of visitors to the künzelsauer wertwiesen, all keen to see the legendary lego model. so apart from skill and patience, the operation of the lego crane also called for a certain amount of queuing. after all, it’s not everyday that you can operate a crane yourself.
