Jackhammer Large
With its 75 joules of single stroke impact energy and only 25 kilograms of weight, the EH 75 electric demolition hammer by Wacker Neuson is unique on the market. Pleasantly light, but powerful in use, it also impresses with its shockwave-optimized, hollow piston percussion system and an asynchronous motor with a carbon brush-free drive. And thanks to its efficient full hood spring mounting, it also offers excellent vibration damping for low hand-arm vibrations. The re-greasing interval was re-tuned and is 30 hours. This saves time and money.
75 joules of single stroke impact energy
25 kg operating weight
4.8 m/s hand-arm vibrations*
Built-in converter protects against drops and peaks in the mains supply
Optimized percussion system
Hollow piston percussion system with striker rod
The patented, shockwave-optimized percussion system provides for an extremely high demolition performance.
* The hand-arm vibration is therefore under the limiting value of 5 m/s. This allows for a continuous use of up to eight working hours per day. According to the EU directive EU 2002/44/EC.
