The good news is growing movement in the hoist sector towards wireless control systems that can ensure greater safety and also less downtime for workers, as well as intelligent devices offering increased levels of manufacturing data. Tom Woerndl stories.

The advent of wireless solutions while in the last decade has found both industrial and consumer technology move towards ‘hands-free’ even more portable products. At the domestic level, the advantages are clear, as such technology can be used by individuals in the property to live more ideally and flexibly.

Likewise, for operators of overhead cranes, wireless solutions—or no less than solutions with fewer wires—are these days becoming more commonplace, with control systems regarding lifting equipment that make use of radio frequencies providing a good number of potential advantages.

Jim Kluck, world product manager for Magnetek-brand handles and automation systems from Columbus McKinnon, a US-based rising and motion control expert, confirms that the hoist sector is moving far from systems that require extensive wiring.

“There’s definitely been a push inside last few years in order to simplify controls and reduces costs of wiring by, for case in point, utilising a point I/O hinder that transmits wired I/O through a single Ethernet cable, combined with Ethernet connections to drives and sensors.

“By reducing how much wiring, troubleshooting becomes a lot easier for operators, who no longer ought to dig through a good number of wires to find the challenge. ”

One knock-on effect associated with fewer wires is supposedly reduced downtime, lower your time costs and smaller cell size. “There is also a price benefit for operators, as they’ll use less copper wiring to get inputs and outputs, ” adds Kluck, who says that crane consumers are increasingly using radio-controlled models to stand further away from loads. “As a outcome, we are seeing a growing number of demand for these kinds of systems with wireless connectivity, although operators still love to have a pendant with regard to back-up. ”

Radio-controlled systems can on top of that simplify and streamline operations by reducing the amount of devices in a production environment that happen to be liable to fail, while also decreasing the quantity of technology that is prone to suffer from wear in addition to tear.

Headquartered in Sweden, but with a bunch of international sites, Tele Stereo recently supplied radio manage systems for 18 electrical overhead travelling cranes on Nortek Air Solutions’s upgraded air handling equipment producing facility in Québec, Nova scotia.

Tele Radio provided each one crane with three Panther receivers: one with the bridge, one for hoist/trolley 1, and the third intended for hoist/trolley 2.

All belonging to the operations are controlled with a single transmitter, with the cranes used by Nortek to lift an array of loads— including custom ventilators, coils and air handlers—which are manufactured for a recently expanded 200, 000 sq foot facility in Montreal.

“A key benefit of our radio-controlled systems over traditional solutions usually we’ve eliminated festooning, ” makes clear Miguel Tellez, managing overseer at Tele Radio. “This means that no cables ought to be installed to control the functions that are handled by each free receiver.

“Consequently, the product is more cost-effective, because festooning are very expensive. In addition, having no cables means that there is absolutely no wear and tear by using those cables. ”

Reported by Tellez, having just one transmitter for every crane also allows fast and easy part replacement in the event of break downs. “In a facility where there are many cranes, each with one among our transmitters installed, a spare transmitter in the same family enables you to replace a damaged just one, ” he continues.

“So if there are 50 cranes, one spare Tele Radio Panther transmitter is known to replace a faulty program. With most of each of our main competitors, a spare transmitter ought for every crane inside facility. ”

Andreas Bahls, income manager at Tele A radio station, adds that the Panther system is easy to set up and operate, while it also benefits from working with 2. 4 GHz, which enables the use of hundreds of systems in the same area. “Our success with this solution means that crane brands and operators now trust wireless systems such as these, ” he makes clear.

Bahls notes that the Panther system can be adapted to almost most of standard overhead crane applications, and one transmitter may operate four separate cranes at home, while multiple transmitters may be allowed to communicate while using same receiver.

Installation of systems for example Panther is usually carried out by the OEM or end user, although Tele Radio offers assistance with special requirements.

For the Nortek undertaking, Canadian Stahl CraneSystems rep CanStahl installed the EIGHTEEN single-girder EOT cranes, 15 of which work in tandem having two hoists. In United states, indoor cranes are typically fitted with wire string hoists but, in this kind of instance, chain hoists were used to lift loads in tandem operation with no sideways movement of the hook.

A total of THIRTY-FIVE new chain hoists with a lifting capacity between TWO, 000 and 5, 000kg ended up installed; the spans belonging to the bridge cranes are around 66 ft (20. 12m), which includes a lifting height of unique hoists between 19. 7 ft (6m) and 26. 2 ft (8m). Many cranes are fitted having 12-button Tele Radio remote computer support controls.

In general phrases, Tellez says the North Us market for control programs has changed significantly from the last two decades. “When I moved towards the US from Spain 15 in years past, it felt a small bit like I was stepping last time, as remote controls was previously a luxury item, ” he / she explains.

“However, as the actual safety and reliability regarding remote controls improved, and the cost of high-end solutions came affordable, applications that require cable control have gradually gone. ”.
