JCB Martillos Contractor Martillos

Our Contractor hydraulic breaker range has been designed for situations where the total project cost is a key factor, as it offers unrivalled value for the rental and construction sectors. Product specifications• Impact energy 300-22,469 J • Long stroke impact rate 230-1,500 bpm • Oil flow 12-272 lpm • Tool diameter 45-175 mm • Pressure 90-210 bar • Weight 120-4,131 kg Contractor breaker rangeThese versatile breakers are fully tested and approved for flow, pressure, compatibility and installation as part of every machine development program we carry out. This, in turn, means that every unit carries the relevant CE certification. Key points• The breakers are delivered ready to use, with hoses*, suspension bracket and moil point included. • *Universal models are available without suspension brackets or hoses to help customers with mixed fleets. • Accumulators ensure complete protection of the machines against sudden increases in hydraulic pressure. • Internal control valves provide greater efficiency and are much less vulnerable than competitors' products with external units. • Available for side mount, top mount or universal use on machinery other than JCB • Vibration-isolating rubber shock absorbers absorb the recoil from hammering, reducing damage to the carrier vehicle. • Automatic greasing as standard on HM080T hammers and larger. • To reduce blank firing, HM080T models and above include an automatic stop function. This prevents inexperienced operators from causing unnecessary wear and damage to the breaker. • The stroke regulators on the HM054T allow operators to adjust the speed and tool stroke length to increase productivity. • The two oval tool retaining pins offer twice the service life of a standard pin. • Rock claw with anti-abrasion tool made from Hardox steel, designed to move material and prepare it for breaking. • Includes gas charging kit, unless otherwise stated. • For complete peace of mind, every Contractor breaker comes with a 3-year warranty. HM330TThe HM330T is fully tested and approved for use on the 370X excavator. • Top mount option: compatible with 90 mm or 100 mm* diameter pins (*using quick coupler). • Impact energy: 8788 J. • Operating weight: 2220-3655 kg.
