51 AGGREGATES MANAGER December 2015 Indeco North America's HP 13001-ABF hydraulic breaker is particularly suited to aggregates ap- plications. Featuring a severe-duty casing, it is designed to fit excavators weighing from 86,000 to 176,000 pounds. Features include a special low-alloy steel construction for longer working life, the manufacturer's unique ABF (anti-blank fire) technology to eliminate damaging blank or dry firing, an intelligent hydraulic system that varies hammer blow and frequency according to material hardness, a dual shock absorber system that reduces vibration, a field-replaceable lower insert bushing, and a power greasing system to reduce wear. The unit weighs 11,150 pounds and delivers 270 to 540 blows per minute. Indeco North America hwww.indeco-breakers.com Montabert's V32 heavy-range hydraulic break- ers feature automatic variable-speed technology that senses changes in material hardness and adjusts impact energy and striking rate, maximiz- ing productivity while reducing harmful energy transferred back to the carrier. The variable-speed system is designed for quarrying and excavat- ing applications. Designed for use on excavators weighing between 39,700 and 66,150 pounds, the 3,408-pound hydraulic breaker delivers be- tween 400 and 1,050 blows per minute. Standard features include a progressive start system that prevents slipping by creating a niche in the mate- rial before full power is applied. A blank-fire pro- tection system reduces metal-on-metal contact, and an energy recovery system recycles recoil energy to increase strike power. Montabert | www.montabert.com Unit features severe-duty casing Variable-speed technology Doosan hydraulic breakers are available in impact energy classes from 2,720 to 10,880 joules and are designed for use with its crawler excavators (DX140LC-5 through the DX350LC-5) and DX140W-5 wheel loader. The breakers fea- ture an energy recovery system that increases strike power for maximum productivity. The nitrogen-powered units are equipped with an upper/lower suspension system that isolates the power unit from the housing. Additional features include a patented main valve design that reduces hydraulic pressure, a suspension system that extends boom life by absorbing vi- bration, and accessories such as a bracket cap, hoses, automatic greaser, and toolbox. Doosan | www.DoosanEquipment.com JCB hydraulic breakers are designed to break a wide range of materials using minimal power for optimal productivity. All combine hydraulic force and recovered energy in the hydraulic system through the use of a highly efficient internal control valve. Energy not absorbed by the rock is reused during the following blow, placing less demand on the carrier. Reused energy requires no additional hydraulic flow from the pump, improving ef- ficiency while saving fuel. All breakers are available with either a moil or chisel tool as standard equipment. The heavy-duty hous- ing is constructed from high wear-resistant steel for reliability across a wide range of applications.

Models range from 10,000 foot pounds to 150,000 foot pounds which easily break materials such as limestone, basalt, granite, trap rock, iron ore, slag, etc. The high, single-blow impact energy, coupled with low maintenance and low wear part costs, make the ham- mers a productive and profitable attachment for all quarry owners and operators.
