If you have ever driven eastbound on the Massachusetts Turnpike by the Lee, Mass., exit you cannot help but miss a quarry of nearly perfect white rock. It turns out that it is a limestone quarry and is called OldCastle Lawn & Garden Northeast. The limestone that comes out of this quarry — and has been coming out since 1877 — is primarily used for agricultural applications.

Fecon's FRS15 is the latest addition to the company's lineup of attachments for 16 to 24 ton (14.5 to 22 t) excavators. Made of Hardox Steel, this shear attachment provides a 360 degree rotation, which gives operators more reach and access to the trees and reduces repositioning of machines.

Genesis Attachments has four new XT Mobile Shear models, increasing the line to eight. The new GXT 445 and GXT 775 straight and rotator models join the GXT 555 and GXT 665 models introduced in April 2013. Shorter in length and height and lighter in weight, the GXT features a center of gravity that is closer to the excavator, enabling the rotating models to mount on 46,000 to 78,000 lb.

Genesis Attachments’ XT mobile shears is designed to process scrap more efficiently and fit on smaller carriers, reducing initial acquisition investments and hourly energy consumption costs, according to the manufacturer. Shorter in length and height and lighter in weight, the GXT features a center of gravity that is closer to the excavator, enabling the GXT 555 and GXT 665 rotating models to mount on 46,000 to 66,000 lb.

Allied Construction Products LLC has added AMS series mobile shears to its full-product line. These all-new Allied AMS series mobile shears are specifically designed and built for scrap processing, industrial contracting and demolition applications. Allied’s newest full-product line addition, the AMS series mobile shears are available in four models (AMS 30, AMS 40, AMS 50 and AMS 100) ranging from 721 to 1,446 tons (654 to 1,312 t) of cutting force.

Mobile scrap processing operations can look forward to productivity and durability equal to the standards of today’s most advanced stationary plants, as Vezzani S.p.A. introduces the new VS Series of transportable shears. The new VS model pre-compression shear is offered as a mobile system in the 600 to 700 ton (544 to 635 t) range that utilizes the same gravity feed system that Vezzani used for its PC/AC stationary shears.

The Geith precision steel shear is available in six different models for excavators from 16.5 to 100 tons (15 to 100 t). Geith precision steel shears feature jaw force, a hydraulic speed valve for a faster work cycle and an interchangeable nose blade to ensure optimal piercing productivity.

Three new Cat B-Series mobile shears — S320B, S325B and S340B — round out the six-model lineup of Caterpillar designed shears. The new shears feature a redesigned lower jaw, wider jaw opening, new knife-retention system, new jaw-adjustment system, greater hydraulic power and boom or stick mounting options.

Fecon has added three new tree shears to its line of excavator attachments. Two models are designed for 12- to 18-ton (11 to 16 t) excavators with 15 to 20 gpm (56.8 to 75.7 Lpm) — the FBS1400EXC and the FBS1500EXC. The FBS1400EXC weighs 2,000 lbs.

Citing a demand from its customers for a shear that provides large-scale results on a smaller-class machine, Genesis has introduced its line of XP Maxx mobile shears. Genesis GXP 660 Maxx and GXP 990 Maxx shears provide power usually found in a shear that is one to two sizes larger, according to Shane Kuhlmey, Genesis’ national sales manager.

In its heyday, the LTV Steel plant in downtown Pittsburgh, PA, represented about ten square miles of steel making facilities. However, changes in global and national economics, a growing reliance upon foreign steel and a push toward mini mills have collectively brought about the demise of the massive steel plant in America.
