There is a growing movement in this hoist sector towards wireless control systems that may ensure greater safety as well as less downtime for guys, as well as intelligent devices that include increased levels of production data. Tom Woerndl stories.
The advent of wireless solutions within the last decade has found both industrial and buyer technology move towards ‘hands-free’ and much more portable products. At any domestic level, the advantages are clear, as such technology can be used by individuals in the home to live more handily and flexibly.
Likewise, with regard to operators of overhead cranes, wireless solutions—or a minimum of solutions with fewer wires—are today becoming more commonplace, with control systems regarding lifting equipment that make use of radio frequencies providing a considerable amount of potential advantages.
Jim Kluck, global product manager for Magnetek-brand regulates and automation systems on Columbus McKinnon, a US-based lifting and motion control consultant, confirms that the hoist sector is moving off from systems that require considerable wiring.
“There’s definitely been a push inside last few years to help simplify controls and reduces costs of wiring by, for case in point, utilising a point I/O obstruct that transmits wired I/O via a single Ethernet cable, and also the Ethernet connections to devices and sensors.
“By reducing the number of wiring, troubleshooting becomes a lot easier for operators, who no longer must dig through several wires to find the issue. ”
One knock-on effect associated with fewer wires is reportedly reduced downtime, lower manual work costs and smaller -panel size. “There is also an expense benefit for operators, as they’ll be using less copper wiring intended for inputs and outputs, ” gives Kluck, who says that crane users are increasingly using radio-controlled models to stand further far from loads. “As a end result, we are seeing a lot more demand for these different types of systems with wireless connectivity, although operators still like to have a pendant regarding back-up. ”
Radio-controlled systems can additionally simplify and streamline operations by reducing the quantity of devices in a production environment which can be liable to fail, while also decreasing the quantity of technology that is more prone to suffer from wear as well as tear.
Headquartered in Sweden, but with a number of international sites, Tele Radio recently supplied radio manage systems for 18 electrical overhead travelling cranes with Nortek Air Solutions’s improved air handling equipment developing facility in Québec, Nova scotia.
Tele Radio provided each crane with three Panther receivers: one for your bridge, one for hoist/trolley A SINGLE, and the third for hoist/trolley 2.
All on the operations are controlled by the single transmitter, with the cranes utilized by Nortek to lift various loads— including custom ventilators, coils and air handlers—which are manufactured at the recently expanded 200, 000 sq ft facility in Montreal.
“A key advantage of our radio-controlled systems over traditional solutions is that we’ve eliminated festooning, ” explains Miguel Tellez, managing director at Tele Radio. “This means that no cables have to be installed to control the functions which might be handled by each independent receiver.
“Consequently, the product is more cost-effective, because festooning could be very expensive. In addition, having no cables means that there isn't a wear and tear together with those cables. ”
Reported by Tellez, having just one transmitter for every crane also allows rapid and easy part replacement just in case of break downs. “In a facility where web sites cranes, each with one of our transmitters installed, a spare transmitter in the same family may be used to replace a damaged one, ” he continues.
“So if you will discover 50 cranes, one spare Tele Radio Panther transmitter can often replace a faulty program. With most of our main competitors, a spare transmitter is needed for every crane in the facility. ”
Andreas Bahls, revenue manager at Tele A radio station, adds that the Panther system is easy to begin and operate, while in addition , it benefits from working in 2. 4 GHz, which enables having hundreds of systems while in the same area. “Our success with this sort of solution means that crane makers and operators now trust wireless systems for instance these, ” he talks about.
Bahls notes that the Panther system might be adapted to almost just about all standard overhead crane applications, and one transmitter can easily operate four separate cranes at home, while multiple transmitters could be allowed to communicate with the same receiver.
Installation of systems such as Panther is usually completed by the OEM or end user, although Tele Radio provides assistance with special specifications.
For the Nortek challenge, Canadian Stahl CraneSystems rep CanStahl installed the 18 single-girder EOT cranes, 15 of which work in tandem having two hoists. In North america, indoor cranes are typically fitted with wire string hoists but, in that instance, chain hoists were used to lift loads in tandem operation with virtually no sideways movement of this hook.
A total of 35 new chain hoists having a lifting capacity between 2, 000 and 5, 000kg were being installed; the spans from the bridge cranes are about 66 ft (20. 12m), using a lifting height of individual hoists between 19. SEVERAL ft (6m) and TWENTY SIX. 2 ft (8m). Most cranes are fitted along with 12-button Tele Radio remote computer repair controls.
In general stipulations, Tellez says the North U . s citizens market for control methods has changed significantly inside the last two decades. “When I moved to the US from Spain 15 in years past, it felt a minute like I was stepping back in time, as remote controls once were a luxury item, ” your dog explains.
“However, as your safety and reliability of remote controls improved, and the money necessary for high-end solutions came down, applications that require cable control have gradually disappeared. ”.
