Scrapyard operators face numerous challenges when it comes to processing waste. First, it comes in a variety of forms, requiring equipment that can handle everything from bulky materials to glass. Second, these materials aren’t always all in one place, so processors must be easy to move from location to location. And third, the scrap just keeps coming, meaning equipment needs to work quickly and reliably with minimal maintenance to stay on the job. ŽĎAS mobile scrap shears check all of these boxes.

PRODUCT OVERVIEW

  • ŽĎAS mobile scrap shear models CNS 400 K and CNS 730 earned gold medals at Central Europe’s International Engineering Fair for their innovative horizontal tool-holding slide-cutting technique.
  • Both models cut more scrap of all types per hour than other products and requires only one operator to remove cut scrap from the shear, simplifying operation and minimizing operating costs.
  • ŽĎAS offers scrap shears with both diesel and electric power to meet different customers’ requirements. For those who prefer diesel, the company relies on Cat® industrial engines — the C4.4 for the CNS 400 K and the C7.1 for the CNS 730.
  • Since Cat engines are regarded as reliable and high quality to ŽĎAS customers, the choice to go with Cat industrial engines was an obvious one. 
  • With scrapyard customers located around the globe, ŽĎAS relies on the Cat dealer network to keep the CNS 400 K and CNS 730 up and running. Regular service of mobile scrap shears is essential and having these products as part of a Cat powered fleet offers a big advantage come maintenance time with savings on service time and expenses.

Cat® Engine Overview

Cat® C4.4

  • The Cat® C4.4 Industrial Diesel Engine is offered in ratings up to 200 hp (150 kW) and peak torque 825 Nm (609 lb-ft) which meet U.S. EPA Tier 4 Final, EU Stage V emission standards.
  • A modular and compact core on the Cat C4.4 makes installing the engine on any number of machine applications a relative breeze.  And when downsizing from five-liter platforms, OEMs can see a 20% reduction in length, 5% reduction in height and 40% reduction in weight of the engine, significantly reducing installation costs.
  • With a 15% increase in power density and 10% increase in torque when compared to its predcessor engine, the compact design of the Cat C4.4 reduces heat loss for more efficient engine output, helping operators conquer even the toughest tasks with relative ease.
  • When compared to similar 6-cylinder platforms, the C4.4 saves more than 18% in fluid consumption and is specially balanced to be its most effective, every day.
  • Built-in clean emissions modules keep the Cat C4.4 performing at its peak while also keeping the air around the work site cleaner.

Cat® C7.1

  • The Cat® C7.1 industrial engine is offered in power ratings up to 320 hp (239 kW) and peak torque 1268 Nm (935 lb-ft) allowing for downsizing while still getting more responsiveness and productivity than ever before.
  • Highly-efficient fuel and turbocharging systems are specially configured to meet a wide range of machine operating cycles while also reducing fuel consumtion, up to 20% when downsizing from a larger engine platform.
  • With technologically-advanced fuel-injection and SCR systems, the C7.1 reduces the need for DEF consumption, so overall costs remain low.
  • The newest thermal management systems and catalysts mean your aftertreatment is fit for the life of your engine.
  • When you've got options, you can keep design and installation costs low. The C7.1 has a wide range of configurable options including one that's fit for your machine application.

ON TOP OF THE SCRAP HEAP

Scrapyard operators face numerous challenges when it comes to processing waste. First, it comes in a variety of forms — metal scrap, cupola scrap, non-ferrous metals, plastics, window profiles and more — requiring equipment that can handle everything from bulky materials to glass. Second, these materials aren’t always all in one place, so processors must be easy to move from location to location. And third, the scrap just keeps coming, meaning equipment needs to work quickly and reliably with minimal maintenance to stay on the job.

ŽĎAS mobile scrap shears check all of these boxes. In fact, the CNS 400 K  (introduced in 2000) and the CNS 730 (introduced in 2009) earned gold medals at Central Europe’s International Engineering Fair for their innovative horizontal tool-holding slide-cutting technique. Both models cut more scrap of all types per hour — up to 12 tons for the CNS 400 K and up to 20 tons for the CNS 730 — than other products. And each requires just one operator to remove cut scrap from the shear, simplifying operation and minimizing costs. The two models’ mobile design also is preferred by many scrapyards, since it takes just minutes to move the shears via a hooklift or flatbed trailer to wherever scrap occurs.

ŽĎAS offers scrap shears with both diesel and electric power to meet different customers’ requirements. For those who prefer diesel, the company relies on Cat® industrial engines — the C4.4 for the CNS 400 K and the C7.1 for the CNS 730.

A CUT ABOVE THE REST 

Long service life is critical for waste processing equipment, considering the challenging environments in which it works. ŽĎAS prides itself on the robust construction of its mobile scrap shears — the CNS 400 K and CNS 730 are built to handle as much force as traditional stationary shears. The engines powering them need to be just as tough, and ŽĎAS experimented with a number of brands before landing on a winner.

Tried and tested. Prior to 2012, various engine manufacturers supplied diesel power for the CNS 400 K and CNS 730 scrap shears. That year, the company launched a competition to choose a preferred supplier, and after evaluating engine parameters and after-sale support, Cat industrial engines rose to the top.

“Caterpillar is a renowned brand worldwide, and our customers regard Cat engines as reliable and high quality,” says Zdeňka Hoblová, commercial manager of ŽĎAS’s engineering division.

One reliable design worldwide. With that decision made, ŽĎAS worked closely with Cat dealer Zeppelin to select and integrate the C4.4 and C7.1 into the CNS 400 K and CNS 730, respectively. Nearly a decade later, the company has no regrets. In addition to dependable, low-maintenance performance, the C4.4 and C7.1 use the same engine core to meet different emissions regulations. That means ŽĎAS can use the same main components in the scrap shears it exports worldwide, saving time and money on design and manufacturing.

Service to support an entire fleet. With scrapyard customers located around the globe, ŽĎAS relies on the Cat dealer network to keep the CNS 400 K and CNS 730 up and running. Regular service of mobile scrap shears is essential and having these products as part of a Cat powered fleet offers a big advantage come maintenance time. “Having Cat engines implemented not only in our shears but also in other equipment operating in scrapyards helps our customers save on service time and expenses,” Hoblová says.

“HAVING CAT® ENGINES implemented not only in our shears but also in other equipment operating in scrapyards helps our customers save on service time and expenses.”
