FEATURE CRANES & HOISTS
CHAIN HOIST IS SUITABLE FOR A BROAD RANGE OF APPLICATIONS
Fitted with four load hooks, the Demag LDC-Q quadro chain hoist allows different load handling attachments to be lifted and transported at the same time. The available sizes enable loads weighing up to 3.2t to be handled safely and efficiently
are also significant factors. Further safety-related functions satisfy at least Performance Level c and Category 2 to EN ISO 13849-1. Besides safety, service is also of major
importance. The generously dimensioned slipping clutch and gearbox, which is maintenance-free for up to 10 years, as well as fast and simple maintenance of

he Demag LDC-Q quadro chain hoist, a series hoist unit from Demag’s DC
range that has a successful track record all over the world, can be used for a wide variety of handling requirements in production and logistics applications. Equipped with four load hooks, LDC-Q units can handle and transport customer-specific load handling attachments or flat components and feed materials to the relevant workstations. The basis for this broad range of
applications is the technology offered by the LDC-D double chain hoist and some dedicated characteristics. For example, these include a design that combines two double chain hoists which have only one drive, which is a special technical feature. This means that only one chain hoist motor transfers power to the other three chain lead-offs of the Demag LDC-Q quadro unit via corresponding connections. Mechanically synchronised hook lead-offs provide for uniform and precise load handling. This arrangement enables loads with an asymmetrical weight distribution up to a ratio of 70:30 to be picked up without any problems. ProHub integrated variable speed
control, which is a feature unique to Demag chain hoists, also permits rated speeds of up to 90 per cent higher in the partial load range. Operators can utilise sizes DC 10 and DC 25 for handling loads weighing up to 3.2t. The Demag LDC-Q quadro chain hoist offers benefits for safe and efficient lifting.

individual components thanks to its modular design, help to make the Demag LDC-Q quadro chain hoist easy to service. These are all important aspects that minimise downtimes and extend the unit’s service life for improved productivity. For control of the Demag LDC-Q quadro chain hoist, operators also benefit from DSC/DSE control pendants with their low-fatigue actuation force for improved ergonomics. To meet specific ergonomics needs, operators can choose between radio controls or cable- connected control pendants that can be integrated into stationary control units. And ultimately, 2D and 3D geometry
models in the Demag Designer tool give owners the opportunity to view a potential solution and its precise arrangement in their existing building and machinery infrastructure already at the pre-planning stage.

Cranes help fabrication facility to expand A
leading UK manufacturer has selected Street Crane to supply and install overhead cranes at a new state-of-the-art
fabrication facility, which will enable the business to expand its services and meet growing customer demand. Thornhill Heat Exchangers is oen of the UK’s leading
manufacturers of rubber gaskets and plate heat exchangers. The company chose Street to help optimise its manufacturing capabilities at a new site in Barnsley, South Yorkshire, which is the base of its engineering division. The team produces a range of large industrial heat exchangers including plate, shell-and tube, and fin-fan as well as large storage vessels. The products are used in a variety of industries including steel manufacturing, food processing, chemical and shipping. Six overhead Street cranes have now been installed in the new facility, one with a lifting capacity of 10
tonnes and five with a lifting capacity of 15 tonnes. The cranes are being used to lift materials such as carbon steel, stainless steel, brass, aluminium and titanium onto machines which are controlled with CNC (computer numerical control) and used to manufacture the heat exchangers. The cranes will also be used to handle the newly fabricated storage vessels which will be produced at the site. “This site is home to a new division which uses the latest technology and will significantly expand our
product range,” says Mark Ingram, general manager at Thornhill Heat Exchangers. “We needed overhead cranes that would enable us to efficiently and reliably move large and heavy materials around the new site, ensuring maximum productivity.We chose Street because it’s a UK manufacturer with a strong reputation. We wanted the assurance that the overhead cranes were of the highest quality and backed by strong after- sales, which to date has been very impressive.” For more information, visit the Street Crane website at:
