Mountainside Unloading picks up rare role with Louisiana-Pacific Mill

Insiders recognize that Larry McKay is a rare species in the lumber processing industry.

As the owner of Mountainside Unloading Ltd., he is under contract to operate the Louisiana-Pacific wood yard in Swan River, Manitoba. 

“I am pretty blessed that they’ve given us this good job,” he said. “L-P usually likes to run its own yards, with its own equipment. But we’re providing a good service to them and they seem to like us.”

Mountainside Unloading opened in 2006, across the road from L-P’s OSB mill about 500 km northwest of Winnipeg. At that time, McKay took over the yard from the original owners who founded it. L-P has diversified Swan River’s product range since then, including OSB. Today the mill is processing about 1 million board feet of finished product per day.

Going green

Mountainside Unloading handles all yard duties for the mill: unloading trucks, stockpiling the yard and feeding wood to the mill’s six conditioning ponds. When McKay acquired the business, it came with seven Prentice ATL 625 loaders. Last year, he sold off the last of his 625s and completed his transition to an all-green fleet of Sennebogen 830 M-T log handlers. 

“I loved those old red machines,” he said. “Prentice made a good machine. But now they’ve been replaced by a great machine.”

The Sennebogen 830 M-T is a purpose-built model for woodyard applications. It is a compact 41,400 kg loader mounted on a rubber-tired undercarriage specially engineered to pull heavy log trailers. McKay recalls purchasing his first two units in 2013, following a visit from Westcon Equipment. 

“At first, the guys on our crews were kind of scared of them,” he laughs. “But after six months, nobody wanted to use the old loaders anymore.”

Extended reach

Those original two machines were equipped with a Sennebogen K14 boom, giving the 830 a reach of 13.7 metres, compared to the 10.7 metre reach of the previous loaders. Building stacks up to 8 metres high, McKay’s operators are usually working at eye-level with their stacks. In fact, it was the height of the 830’s elevating cabs that, at first, made them wary of riding in it. Soon, though, they found that extra cab height made stacking a simpler and safer process. The square footprint of the 830 also gives operators a stable 360-degree lift radius, allowing them to work efficiently between tight rows with minimal maneuvering.

Efficient rotation

Over the next two years, McKay added two more of the same machines to his fleet, matching his equipment with his 12-man crew rotation. At least two 830s are running day and night, often three when truck traffic is busy through the winter months. 

The crews work 12-hour shifts with a pair of operators alternating days and nights on each machine, four days on and four off.  When they finish their shift block, the machines come in for cleaning and service, while the other two units go out for the next four-day cycle. Typically, the yard handles 160 trucks of poplar wood per day, with about 50 truckloads going straight to the mill while the rest is stockpiled in the yard.

Changes in loader tech

Reflecting on the change in loader technology, McKay notes that 10 years ago, he had 2-wheel-drive Prentice machines pulling 23,000 kg trailer loads. With the new 830s, the yard now has four-wheel-drive machines with dual transmissions capable of pulling 100,000 loads through 15 cm of wet clay, day in and day out.

Last year, McKay added a fifth 830: this one fitted with the longer K19 boom that provides additional 3 metres of reach for high stacking. 

The objective is to build up the stocks before the roads are restricted by summer rains and mud. He is shooting for 240,000 cubic-metre stocked to be in the yard by spring. While this unit is dedicated to stacking duties, its real purpose is to reduce operating hours for the fleet.

Sharing the load 

“With this rotation, we can keep these Sennebogen’s going forever. They’re a well-built machine, and I’m lucky to have some very smart fellows here to maintain our equipment.” McKay said.

He also credits his factory service rep in Stanley, North Carolina, for providing the support his technicians needed in the early days to learn their way around the new machines. 

“Here we were, 2,000 miles apart from each other, and he would troubleshoot for us right over the telephone,” McKay said. “Hat’s off to that man, he gave us a lot of help.”

Despite the distance to McKay’s remote location (500 km North of Winnipeg), he relies on Westcon for quick delivery of any service parts.

“If I need it, they can get it here within 48 hours. The parts warehouse in Stanley is a massive place. I ordered a few of their Uptime Kits and I’m glad I did. They also seem able to get urgent parts on an airplane and — bang — it’s in Winnipeg and on a bus to us the following day.”

The reliability of Mountainside Unloading’s service is what earned the firm its place in the Louisiana-Pacific supply chain. 

With his five Sennebogen machines, McKay has the capacity he needs to meet the requirements of a very productive mill, plus the flexibility to maintain a thorough service discipline that will deliver long life and reliable uptime without fail. 

“It’s time sensitive to get this wood in like we do,” McKay said. “It’s a pretty impressive feat, what my boys are doing.”
