CRANES AND HOISTS German crane technology from Stahl CraneSystems is in demand in Turkey too The Turkish company Parlak Sistem has been supplying crane systems to the Turkish industry as a partner of Stahl CraneSystems GmbH, Kuenzelsau/Germany, for ten years now. In recent years the company has been able to establish an efficient network of Turkish crane builders. Parlak Sistem advises crane builders on selecting and dimensioning hoists and organises ordering and delivery, in this way offering Turkish companies access to Stahl CraneSystems’ universally acclaimed hoists and crane components. J ust recently Parlak Sistem supplied a crane system to a major Turkish paper manufacturer – built in Turkey, equipped with hoists and crane components from Stahl CraneSystems. The company needed a reliable crane for demanding day-to-day use in production, transporting heavy paper reels. The existing crane was no longer state of the art and needed to be replaced by a more efficient crane system. The crane system designed by Parlak Sistem comprises a double girder overhead travelling crane with two wire rope hoists on double rail crabs and a total safe working load of 25 t. It makes use of the existing 188 m long crane runway, and is equipped with open conductor lines as power supply. Synchronised hoists and reliable collision protection ensure the safety of the system. The crane is operated by radio. Heavy duty conditions Humidity of up to 90 percent and ambient temperatures up to +50°C meant that building the system with standard crane technology was not an option. Stahl CraneSystems thus designed the crane system as a customised solution with climatised control cabinets. High operating time requirements added to the difficulty: the production cranes are in use 16 hours a day, 7 days a week, a problem solved by the use of two high-classification SH wire rope hoists of 20 t safe working load each. Short installation time The contact to the paper manufacturer, who operates 6 plants in Turkey and employs over 1,200 staff, came about at the WIN-Materials Handling Trade Fair in Istanbul, where Parlak Sistem had its own stand. Parlak was able to win the contract against two German and three Turkish competitors thanks to its technically sophisticated crane solution and excellent on-the-spot service. Parlak was able to meet the customer’s exacting requirements during installation too: the old crane was dismantled and the new one erected over the course of a single weekend, thanks to efficient work by two independent erection teams from Parlak Sistem. The outcome of the customer’s positive experience is that the company has already received followup orders. Germany is Turkey’s largest trade partner and German products are much in demand in Turkey. The positive relationship between the two countries is reinforced by personal connections: many Turks who have grown up in Germany return to Turkey and set up their own companies there. Stahl CraneSystems profits from the good contacts to Turkey, as Turkish companies frequently do not just supply products to Turkey, but also have a good relationship with neighbouring countries. Photo: Stahl CraneSystems About Stahl CraneSystems Stahl CraneSystems GmbH, with head office in Künzelsau/ Germany, has more than 120 years experience in crane construction. The manufacturer offers a full range of crane technology and crane components, including chain and rope hoists, winches, and light and small crane systems, as well as drive and control solutions. It is a world leader in explosion protected crane technology. Indeed, Stahl Cranesystems developed the first components for such applications as far back as 1926, thus contributing to today’s industrial standards. The company manufactures its products at the Künzelsau plant, but has 9 foreign subsidiaries. It has 700 employees worldwide.

Product News A-Safe has developed “intelligent” collision protection Absorbers from Ambelt improve cost effectiveness of conveying systems A-Safe, the manufacturer of plastic barriers, has developed the material Memaplex – a robust and flexible polymer compound. Pallet racks with collision protection systems made of this material thus have an “integrated memory”, which means any forces that are applied are optimally absorbed and carefully dispersed. The collision protection systems return to their original shape and remain intact following a collision. In contrast to metal barriers, where practically 100% of the collision energy is transferred in to the floor and the barrier can no longer be used, the manufacturer’s plastic barriers only transfer 20% of the collision energy in to the floor. This consequently reduces the amount of damage, and repair and replacement costs are reduced. A-Safe has numerous international branches and with a company history that dates back 30 years, it is one of the leading suppliers of collision protection systems made of polymers. The products are tested in the company’s own TÜV certified test centers. Dust, sharp objects or heavy bagged materials: conveyor belts are constantly “under attack”. This can result in the need for repairs and subsequently has a negative impact on productivity. This can be avoided with absorbers from Ambelt which can thus, amongst other things, increase the service life of the conveyor belt. The absorbers are made of a highly elastic, shock-absorbing rubber core and a polyethylene sliding layer that guarantees minimal friction. The absorbers also include vulcanized aluminum profiles that enable the fast assembly of elements using T-bolts. These absorbers are available in dimensions of 100 × 100 × 1,240, 75 × 100 × 1,240 and 50 × 100 × 1,240 mm (H × W × L). The absorbers are used for each adapter in the existing support roller stations or are installed on a plant-specific substructure made of steel which is subsequently assembled in the feed area. The latter option particularly applies to heavy material with a high impact energy that is being conveyed. Measurement system from Ametras provides precise volume data throughout the process To date, laser systems with complex technology for which a lot of mirrors and other auxiliary equipment would have be installed, were used, for example, if a logistics service provider wanted to determine the volume of the palettes being dispatched. However, with the newly developed APF volume+ volume system from Ametras, the measurement process can be executed using conventional high-resolution cameras. During this process, a pattern is projected on to the batch using an infrared beam and the height profile is determined based on an algorithm. In conjunction with all types of weighing systems, the volume and weight data can be integrated harmoniously into the work process. If the cameras are installed directly on the doors of the warehouse, the volume and weight can quickly be determined during the unloading/loading process and complete relations can be measured. The users thus have the option to optimize the warehouse on the one hand and on the other, can take the weight and volume of bulk materials into consideration when calculating the price. APF volume+ is available as a standalone solution and as a module for the APF video+ video system. If APF video+ is already being used, the package data is also displayed here and can be processed directly. A standardized interface to most shipping systems or the booking systems of the shipping companies ensures that fully automated discrepancy lists can be created. f+h Intralogistics 1/2015 41
