The US$20,000 Shannon Solo - remote-control, construction industry workhorse carries 500 kg

The Shannon Solo Dumper is an easy-to-operate, remote-control, 4WD, high-tipper-dumper with a carrying capacity of 500 kg and remote-control-range of 100 metres. It has been so successful, that so well received that Fire Hose, Sprayer and Mower versions have been added.

The Shannon Solo is one of those ideas which stands out as a winner from the moment you realise what it is, how much safer it can make things, and how much work it can do. Manual labour is hard work. It also costs a lot, partly because it's labour-intensive and partly because human beings cost a lot of money to keep safe and insure.

British entrepreneurs Stuart Selway and Ryan Symes recognized the health and safety trends affecting the construction (and related) industries several years ago because they were running a construction hire company and were constantly being asked for machinery which would make workers safer. They tried to find a suitable remote control base vehicle to facilitate what they had in mind, and couldn't find one.

So they drew up what they wanted and built it.

The result is the Shannon Solo, which has a hydraulic, four-wheel-drive base vehicle capable of traveling at 8 mph and of climbing inclines up to 25 degrees. Initially conceived as a dumper, the base 16 hp motive unit has now been adapted to a range of applications, with more to come.

The most obvious advantage of the Solo in each of its guises is that it removes the operator from harm's way. The remote controlled Solo machines can operate in hazardous areas without risk to the operator. The potential for the application of the Solo Dumper in common situations where people are normally at risk stretches the imagination - quarries, near deep water, road and freeway repairs, airports, power stations, railway sites, construction sites, contaminated land, demolition sites or areas where there is a risk of falling debris.

Similarly, the Shannon Solo Dumper will find application almost anywhere where a normal dumper is used where there is unstable ground or steep gradients where there is a risk that a normal mini dumper could topple and injure the operator.

The Dumper can also reduce risk if the operational site is adjacent to deep water such as alongside rivers or canals. Quite clearly, there is no shortage of work for the Shannon Dumper because it can considerably reduce the number of times a person is exposed to danger.

The Shannon Solo Firehose is the perfect tool for tackling dangerous industrial building fires where there is a high risk of exploding gas bottles or chemical exposure. It connects quickly to a standard fire hose and can approach dangers for the spraying of water or foam without high risk to the operator who will be 100 metres further away from the danger. The fire hose can also be angled into different positions to direct water jets accurately.

Shannon also sees application of the Solo Fire Hose in dust suppression in quarries, crowd control, demolition sites and for aerating ponds, lakes or rivers, delivering up to 900 litres per minute at 10 bar pressure. Using the optional auxiliary oil supply the SOLO is capable of running hydraulic tools up to 20 litres per minute via quick release couplings.

The list price of the Solo Firehose is GBP19,500 though this can be reduced by GBP2,500 if the company concerned already has its own fire monitor.

State probes deaths of workers in Durham manhole

State inspectors were investigating Wednesday how two workers for a Burlington company became trapped in a manhole in Durham Tuesday evening and died.

Jesus Martinez Benitez, 32, of Clayton, and Luis Castaneda Gomez, 34, of Durham, were working for Triangle Grading and Paving when they became trapped in a manhole at U.S. Highway 70, near Leesville Road, shortly before 6 p.m., authorities said.

Allen McNeely, deputy director of the state Division of Occupational Safety and Health, said that one of the men went down the manhole and suffocated when he was deprived of oxygen. The other man saw his co-worker was in trouble and went into the hole to rescue him and also suffocated, McNeely said.

"What you've got down in the bottom (of the hole) is any number of things – whatever is connected to that manhole, could be methane gas or could be any number of things – that would cause oxygen deprivation," McNeely said.

The Bethesda Volunteer Fire Department and the Durham County Hazmat Team tested the area before sending someone down into the manhole to extract the bodies and found that oxygen levels were too low to sustain life, said Capt. Don Ladd of the Durham County Sheriff's Office.

A passerby who called 911 to report the incident yelled down into the manhole at least twice but received no response from the men.

"I'm looking down in the hole, and these two guys are completely out," the caller told the 911 dispatcher.

The manhole led to an underground access point for utilities, according to Ladd, who described the space inside as a 4- by 6-foot concrete bunker about 10 to 12 feet below the surface.

Ladd said it was unclear what the men were doing in the manhole, although they might have been trying to remove a piece of equipment or open a valve.

Durham is adding water lines along U.S. 70 in the area, officials said.

Eight workplace health and safety complaints have been filed against Triangle Grading and Paving in the past 14 years, according to U.S. Occupational Safety and Health Administration records. One worker was killed in 1997 when a hydraulic hose ruptured and caused the bulldozer he was operating to catch fire, records show.

The company was fined $40,000 last year for serious and willful safety violations for exposing employees to hazards while working in an 8-foot-deep trench at Fort Bragg, records show.

"An employer is responsible for making sure confined spaces are monitored, so you know what's going on down there," McNeely said. "That's some of the things we'll be checking on, that and training the individuals, making sure they knew what they were working on."

Triangle Grading and Paving officials issued a statement Wednesday expressing sorrow at the men's deaths and stating that the firm is dedicated to ensuring worker safety and is cooperating in the state investigation.

"We take great pride in our safety and education programs at Triangle. We do everything in our power to prevent injuries and deaths in a dangerous occupation," the statement said.
