HM1570Q JCB HM1570Q Specifications & Technical Data (2017—2026)

Efficiency

To get jobs done quickly and efficiently, JCB Hammermasters are designed to break as much material as possible using minimal power. Amongst other things, these tools are fitted with numerous innovative, versatility-boosting features.

Protective features

To improve the longevity of Hammermaster components, our Autostop feature reduces blank firing. This provides excellent protection against unnecessary wear for the tools and tool retaining pins, especially when working in low visibility areas (eg. trenching). Additionally, HM1770Q-HM3070Q Hammermasters can be used in Autostart mode which is ideal when breaking less stable material.

Minimal servicing, made easy

Because our Autostop feature reduces blank firing, the breaker is protected from excess wear, keeping your Hammermaster breaking for longer. Service intervals are extended and cost of ownership is reduced accordingly. Once the tool has broken the rock, the breaker stops further blows automatically. Breaking material can be a dusty task, so we’ve equipped the range with extensive dust protection to guard internals, provide long life, and reduce grease consumption. Our active single-stage seal is highly effective against rock, debris, and dust, protecting components like bushings, the impact ring, retainer bars, and the piston. We provide a specially tailored toolbox with every Hammermaster so that your operators have everything they need to remove pins and re-gas the breaker, saving time on site.

Full length cylinder sleeve.

Whether the monoblock or standard design, all JCB large Hammermasters feature a replaceable outer shell. This protective layer takes all the knocks from your tasks and, being made of Hardox, it is designed to last and protect the internal components. HM870Q - HM1270Q - HM1570Q Monoblock Design Should tie rods fail, significant damage to the breaker will follow. HM870Q-HM1570Q have a unique fastening system which does not use long side bolts. Due to this design, the potential for leaks is reduced. The Monoblock design removes strains associated with bending forces and increases the life of the Hammermaster. HM1770Q - HM2470Q - HM3070Q Standard Design HM1770Q-HM3070Q models uses head bolts with helicoil insert threads designed to distribute torque load equally. This means that routine servicing can be done on site without the need for specialist tools, reducing downtime.
