Breaking and Moving

Rapid inventory turn-around in scrap yards and the controlled demolition trend in that industry are among the factors boosting the sale of mobile shears and other attachments that do more than simply move scrap material.

Without question, the scrap boom is causing grapples and lifting magnets to work overtime just as much as any other equipment in a scrap yard. And stationary processing equipment—from the alligator shear to the super-sized shredder—is humming along nicely in most regions.

But a growing number of orders have also been placed for mobile shears and multi-functional variations of this hydraulic attachment that are used by demolition contractors and the scrap processors who handle demolition scrap.

INSIDE JOB. Demolition contractors use compact excavators and skid steers outfitted with a variety of attachments to perform "infrastructure" demolition, or the removal of plumbing and heating and electrical systems within a building.

"In controlled demolition the contractor will normally remove any material with salvage value, such as wires, conduits, pipes and electrical equipment, using small shears and grapples on skid-steer loaders or mini- or standard-size excavators," Poul Rosengaard, senior application engineer for Caterpillar Work Tools, Peoria, Ill., says.

"Due to the compact size, low weight and speed of skid-steer loaders, these machines are becoming much more popular in demolition applications," Rosengaard continues. "Also, with the ever-increasing versatility and great selection of work tools available for the skid-steer loader, they are widely used in selective demolition jobs, like refurbishment of residential and office buildings. The use of skid-steer loader machines and the appropriate work tools are often needed when working within the city limits."

In addition to demolishing structures, demolition contractors face a variety of recycling-related tasks, including the primary sizing and separation of material. This necessitates a number of tools, though just how many depends on the size and nature of the job and the time constraints a contractor faces, Cat's Rosengaard says.

Kevin Loumas at West Springfield, Mass.-based Atlas Copco, says the use of these carriers, equipped with either hydraulic hammers, grapples, shears or pulverizers, has increased greatly during the last eight years.

"They have a variety of attachments, plus they are light and they can work in confined areas, especially the compact excavators," Tom Witt, director of sales for Breaker Technology Inc., Thornbury, Ont., says.

While he says compact excavators are nice because they can sit in one spot and reach around to demolish the surrounding areas, a skid steer equipped with a bucket is ideal for picking up material and loading it out.

The two carriers, equipped with various attachments and used in combination, could provide contractors with an expedient solution for interior and infrastructure demolition tasks.

YARD WORK. At the scrap yard, recyclers eager to process incoming demo scrap efficiently to fill waiting orders have turned to mobile equipment with attachments to help increase production.
