‘Workhorse’ still hard at work – after 73 years

A vibrating screen remains an important part of an aggregates operation more than 70 years after its purchase.

The RE Law Crushed Stone quarry near Port Colborne in Ontario, Canada, bought its oldest operating machine on 20 March, 1943. The vibrating screen shipped two months later.

The machine was then sold to Hard Rock Paving Co along with the quarry in 1977.

The Waterford Group bought the operation in 2008 and today uses the vibrating screen at a quarry in Uxbridge, Ontario. Its operators say it still works flawlessly.

“It’s one of the best running machines on the site,” Waterford Group site supervisor Brandon Smith said.
“When it was put in my care last [northern] spring, it had been sitting idle for six years at our head office, so I was sceptical. But we did some minor repairs, started it up and it didn’t miss a beat.”

The 1.2m x 3m vibrating screen was called a Ty-Rock screen when RE Law Crushed Stone purchased it in 1943. Its modern day counterpart is the Haver & Boecker Tyler F-Class vibrating screen, which minimises vibration transmission to the surrounding structure due to its four-bearing technology.

Waterford’s machine still has the original beds but has had a few updates, including new paint and added spray bars.

There have been no major refurbishments to the vibrating screen over the years and no major repairs of which Smith is aware. The Ty-Rock spent most of its life screening crushed limestone, and now Waterford uses it to screen natural sand and gravel.

“I usually expect 25 to 30 years out of a vibrating screen, so it’s amazing that this one is still running perfectly,” Smith said.

“We spend a lot of money when purchasing equipment like this, so we expect it to last. Downtime is huge for an operation like ours because we’re paid by the tonne, not the hour. When we have a machine that doesn’t quit, we keep using it.”

“Our F-Class vibrating screens are built for longevity, so I’m not surprised at all that this one is still in operation after so long,” Haver & Boecker engineered screen media and OEM parts manager Steve Fair said. “The F-Class is our signature machine. It’s our workhorse. And the fact that this machine is still operating more than 70 years later proves our equipment lasts.”

Smith said the Ty-Rock had always been serviced with F-Class OEM parts and screen media.

Fair works closely with Smith to provide screen media and parts for Waterford Group’s machines when it needs them.

“Besides the overall quality of the F-Class, a key reason I believe this machine continues to run so well is that the Waterford Group uses OEM parts,” Fair said. “There’s always a risk of damage to the entire vibrating screen when using non-OEM components fabricated without the exact specifications. The repair costs and production loss often costs many times more than an OEM part would have in the first place.”

The original RE Law Quarry opened in 1937. Current owner Waterford is a diverse company that serves many facets of the Canadian construction industry through supply of natural stone and sands, premium washed and unwashed limestone products, recycled asphalt, concrete products and ready-mix concrete.

The year that was...

When the Ty-Rock vibrating screen was originally purchased in 1943:

  • Franklin Roosevelt was US President. There have since been another 12 Presidents of the United States.
  • John Curtin was Prime Minister of Australia. There have since been another 16 Australian PMs.
  • There was a failed assassination attempt on Adolf Hitler.
  • Italy surrendered to the Allies in the Second World War and a few months later declared war on Axis partner Germany.
  • Lt John F Kennedy’s PT-boat 109 sank off the Solomon Islands (he would, of course, become US President in 1960).
  • Serbian-American physicist Nikola Tesla died, aged 86.
  • Musician Frank Sinatra debuted on radio’s Your Hit Parade.
  • Rolling Stones vocalist Mick Jagger was born in Dartford, Kent.
  • Actor Robert de Niro was born in New York.
  • Doors vocalist Jim Morrison was born in Melbourne, Florida (died of a heroin overdose in 1971).
  • American actress Sharon Tate was born in Dallas, Texas (she was murdered by the Manson Family in August 1969).
  • Richmond Football Club won the Victorian Football League premiership (defeating Essendon by five points in the grand final).
  • Newtown Leagues Club won the New South Wales Rugby League premiership (defeating North Sydney Leagues Club 34-7 in the decider). Financial pressures forced Newtown out of the NSWRL in 1983.
