scrap shear showdown

Published 27/12, 2019 at 17:36

The development of the scrap shear was pioneered in the US in the 1980s by such giants of the excavator attachment industry as Roy Labounty and Bruce Bacon. Since its inception, the shear design has gone through a number of iterations before acquiring its current look. Today’s scrap shear is a staple item in every respectable attachment supplier’s arsenal, with European and Asian manufacturers steadily gaining ground on their North American counterparts. PDi’s Andrei Bushmarin presents the latest updates in the scrap shear market.

The FS145 - a new kid on the ShearCore block 

Based in Superior, Wisconsin, ShearCore has introduced this year its new FS145 mobile shear, the largest in the company’s product line of attachments for the demolition and scrap recycling industries. Lead designer, Ross Christenson says about the new model; “The FS145 shear has been designed with less welds, fewer pieces, and is structurally stronger.” Bruce Bacon, president of the Exodus Group, states: “The new FS145 shear model is the culmination of the company’s design policy of, ‘begin every design with a foundation in experience and a desire to improve’. This shear model exemplifies that policy with a new tip design to handle the massive force this shear delivers. A new ‘shark fin’ rear lug design transfers stress in a new and improved method over any previous design in the mobile shear world, which allows higher forces to be distributed over greater mass. What this means to the customer is that this shear punches above its weight class; a big advantage in the steel processing world.” Weighing in at 12.7t, the rotating FS145R has a jaw opening of 1.2m and a reach of 4.5m. The minimum excavator boom mount is 65.7t while the minimum stick mount is 113t. The FS145 is also available as a non-rotating model. The FS145 now brings ShearCore’s Fortress mobile shear range to eight models. The Fortress line also includes the concrete processor ‘cracker’ series.

LaBounty expands ‘Legend’ series 

Starting April 2020, US based trendsetter in scrap shears LaBounty will start rolling out four new Legend models. The new shears are equipped with the full protection indexable piercing tip, ‘Dual Max Indexable Protection’, which defends the shear from wear, reduces the need for maintenance and hence any downtime. The Legend’s jaw design also produces up to 10% more cutting force than previous offerings. The attachments feature the ‘InSite’ advanced telematics platform that provides actionable information about the shears’ condition and activity, such as job tracking, jobsite mapping and remote diagnostics. With the InSite app, available for iOS and Android, users have access to valuable information in order to optimise shear performance.

New Demarec DXS mobile shears with ‘DemaPower’ 2.0 cylinder

The brand new Demarec DXS-40 and DXS-50 mobile scrap shears are engineered to deliver high cutting force and optimal performance to weight ratio thanks to patented DemaPower 2.0 cylinder technology. Unlike a conventional cylinder technique utilising two oil chambers, DemaPower 2.0 technology is based on four cylinder chambers, two way oil regeneration for open to close operations in combination with high shearing forces, which results in very fast cycle times. The DemaPower 2.0 system generates 25% more power which results in a closing force equivalent to that of a shear one or two sizes up. The speed valve works in two directions during opening and closing. If the jaw senses resistance during closing, the valve switches from ‘speed mode’ to ‘power mode’ and the full cylinder force from the DemaPower 2.0 cylinder becomes immediately available. According to the Dutch manufacturer, the DXS shears deliver up to 20 -30% more performance than rival brands, whilst reduced fuel consumption is another benefit of this solution. The DXS-40’s and DXS-50’s other remarkable features include a powerful swivel to avoid high oil temperature and ensure high working speed, with the patented ‘DemaSafety System’ protecting the cylinder against excessive pressures (above 450 bar) on the rod side of the cylinder.

RSS range from Rammer 

The Scrap Shear Range (RSS) from Finland based Sandvik company Rammer, comprises of nine models, fitting 4t to 90t carriers. Manufactured from wear resistant HB400 steel, the shears feature hydraulic rotation, rotation protection, heat treated pins and bushings as well as weld free cylinder rods. All new models are equipped with a speed valve for improved cycle times, whereas a smart jaw design allows the material being cut to fall away from the cutting area, thus enhancing performance and increasing uptime. A central pin adjustment system helps prevent jaw deviation to maintain maximum cutting performance. This system has been proven to reduce operating costs by minimising the amount of material stuck in the jaws.

Hydraram rolls out the ‘Terminator’ 

Netherlands based Hydraram has recently shipped the first units of its newly developed HRS-27T scrap shears to customers in Germany and Australia. The letter ‘T’ in the model designation stands for ‘Terminator’, which speaks volumes about the shear’s power and efficiency. Weighing in at 2,680kg, the new model boasts a jaw opening of 855mm and delivers high cutting force. Due to the combination of wide jaws and relatively low weight, this model is ideal for mounting on long front excavators. Made from Hardox ‘Hituf’ steel, the shear is equipped with two hydraulic motors, two reversed cylinders and a double bearing slewing ring. With a working pressure of 350bar and an oil flow of 250-350bar, the HRS-27T fits 23t to 34t machines or long front excavators which can carry a weight of up to 3,000kg. With a cutting force of 120t at the tip and 540t in the middle of the rear blade, the shear is capable of cutting 600mm x 300mm I-beams with thicknesses of 12mm x 17mm.
