You will find there's growing movement in the particular hoist sector towards wireless control systems which could ensure greater safety along with less downtime for guys, as well as intelligent devices that include increased levels of production data. Tom Woerndl reports.
The advent of wireless solutions inside the last decade has noticed both industrial and customer technology move towards ‘hands-free’ and much more portable products. At a new domestic level, the rewards are clear, as such technology can be used by individuals in the home to live more handily and flexibly.
Likewise, to get operators of overhead cranes, wireless solutions—or at least solutions with fewer wires—are at this point becoming more commonplace, with control systems with regard to lifting equipment that use radio frequencies providing a nice selection of potential advantages.
Jim Kluck, world wide product manager for Magnetek-brand handles and automation systems from Columbus McKinnon, a US-based rising and motion control specialized, confirms that the hoist sector is moving from systems that require considerable wiring.
“There’s definitely been a push while in the last few years that will simplify controls and streamline wiring by, for model, utilising a point I/O block that transmits wired I/O via a single Ethernet cable, along with the Ethernet connections to driving and sensors.
“By reducing the quality of wiring, troubleshooting becomes a lot easier for operators, who no longer need to dig through lots of wires to find the challenge. ”
One knock-on effect with fewer wires is reported to be reduced downtime, lower manual work costs and smaller mother board size. “There is also an expense benefit for operators, as they’ll workout on less copper wiring for inputs and outputs, ” brings Kluck, who says that crane customers are increasingly using radio-controlled systems to stand further far from loads. “As a consequence, we are seeing progressively more demand for these varieties of systems with wireless connectivity, although operators still like to have a pendant for back-up. ”
Radio-controlled systems can also simplify and streamline operations by reducing the number of devices in a production environment that are liable to fail, while also decreasing the amount of technology that is more likely to suffer from wear along with tear.
Headquartered in Sweden, but with some international sites, Tele Stereo recently supplied radio command systems for 18 utility overhead travelling cranes with Nortek Air Solutions’s improved air handling equipment production facility in Québec, The us.
Tele Radio provided each one crane with three Panther receivers: one with the bridge, one for hoist/trolley YOU, and the third pertaining to hoist/trolley 2.
All belonging to the operations are controlled by a single transmitter, with the cranes utilised by Nortek to lift various loads— including custom ventilators, coils and air handlers—which are manufactured at a recently expanded 200, 000 sq ft facility in Montreal.
“A key advantage of our radio-controlled systems over traditional solutions is always that we’ve eliminated festooning, ” makes clear Miguel Tellez, managing overseer at Tele Radio. “This means that no cables has to be installed to control the functions that happen to be handled by each unbiased receiver.
“Consequently, the technique are more cost-effective, because festooning are very expensive. In addition, having no cables means that there isn't any wear and tear having those cables. ”
Based on Tellez, having just one transmitter per crane also allows speedy and easy part replacement just in case of break downs. “In a facility where there are many cranes, each with certainly one of our transmitters installed, a spare transmitter with the same family may be used to replace a damaged one, ” he continues.
“So if you will find 50 cranes, one spare Tele Radio Panther transmitter can be used to replace a faulty program. With most of our own main competitors, a spare transmitter is required for every crane inside the facility. ”
Andreas Bahls, income manager at Tele Stereo, adds that the Panther system is easy to put together and operate, while this also benefits from working from 2. 4 GHz, which enables using hundreds of systems inside the same area. “Our success with such type of solution means that crane brands and operators now trust wireless systems for instance these, ” he explains.
Bahls notes that the Panther system is often adapted to almost many standard overhead crane applications, and one transmitter might operate four separate cranes individually, while multiple transmitters is often allowed to communicate when using the same receiver.
Installation of systems such as Panther is usually performed by the OEM or end user, although Tele Radio offers assistance with special specifications.
For the Nortek undertaking, Canadian Stahl CraneSystems rep CanStahl installed the 18 single-girder EOT cranes, 15 of which work in tandem with two hoists. In North america, indoor cranes are normally fitted with wire string hoists but, in this specific instance, chain hoists were familiar with lift loads in tandem operation with no sideways movement of the particular hook.
A total of 30 new chain hoists which has a lifting capacity between ONLY TWO, 000 and 5, 000kg have been installed; the spans of the bridge cranes are about 66 ft (20. 12m), which has a lifting height of individual hoists between 19. 6 ft (6m) and 26. 2 ft (8m). All cranes are fitted with 12-button Tele Radio remote computer repair controls.
In general words, Tellez says the North U . s . market for control devices has changed significantly in the last two decades. “When I moved to the US from Spain 15 typical, it felt a little bit like I was stepping last time, as remote controls was previously a luxury item, ” this individual explains.
“However, as the actual safety and reliability associated with remote controls improved, and the price tag on high-end solutions came lower, applications that require wire control have gradually vanished. ”.
