BREAKERS ATTACHMENTS ROUNDUP Boom mounts on portable crushing plant The Indeco portable pedestal boom is designed to mount on a portable crushing plant The versatile unit can be supplied with a power pack or run off the crushers hydraulic system Its mobility allows for more freedom of reach which results in an increase of production by as much as 30 percent the company says The optional wireless remote control box makes it possible to operate the pedestal boom without a dedicated operator www indeco breakers com Breaker frequency easily adjusted Delivering up to 600 bpm the Doosan 5400 lb DXB260H hydraulic breaker is designed for use with excavators in the 27 to 37 metric ton weight range specifically the Doosan DX300LC and DX350LC With two speeds the DXB260H breaker frequency can be easily adjusted between short and long stroke settings Standard features include a cradlemounted grease station Blank fire protection uses a cushion of oil at the base of the cylinder to reduce metal to metal contact A patented main valve design reduces hydraulic pressure peaks that can reduce pump life crack excavator workgroup welds and cause system overheating Finally an energy recovery system on the DXB260H increases strike power by using energy generated by piston rebound www doosanequipment com Screening bucket features modernized shape The new Evolution Pro replaces all old Remu screening buckets The new design protects the hydraulic motors and hoses of the bucket from impact and wearing reducing damage risk and maintenance The shape of the bucket has been modernized which will bring many improvements for its use For example the sides of the bucket are straighter so that even wet material will pass through smoothly Bolted couplings make each bucket usable with multiple base machines and the unit features a bolt on mounting configuration for excavators and wheel loaders making it easier and faster to change the bucket from one machine to another www remu fi Breakers reinforced suspension absorbs vibration Tramacs V4500 is part of the companys line of heavy breakers boasting the same engineering and high durability found in the V1800 and the V2500 the company says It features blank firing protection to prevent metal on metal contact Its pressure regulator valve prevents overpressure and accidental overflow Reinforced suspension absorbs vibration that leads to premature wear to the boom An automatic pressure regulator ensures constant operation despite variations in flow or temperature An automatic frequency adaptation system provides an optimal beat per minute and strike force for the material being worked on www tramacus com 46 PIT QUARRY May 2012 www pitandquarry com
