Rammer 1533 benefits from a radical lightweight design thereby which gives this hammer a class-leading power-to-weight ratio that enables customers to enjoy high levels of productivity in a wide variety of demolition, recycling, quarrying and other associated applications.
The Ramdata II monitors vital functions including working hours, operating method and shift duration, using this information to help predict failures before they occur and schedule service and maintenance.
Ramlube I (Optional)
Carrier mounted greasing device
The twin-handed design allows optimal mounting on both left and right handed carriers, prolonging the service life of the hose connections.
Ramlube II (Optional)
Mounted greasing device, with adjustable flow and cartridge feed.
Ramlube III (Optional)
A built in greasing device, that is ideal for working in colder climates as the grease is warmed allong with the product.
Membrane type accumulator
Membrane-type accumulator eliminates Nitrogen leakages, ensuring constant maximum impact power and eliminating the need for recharging in field.
FBE (Fixed blow energy)
The built-in pressure control valve maintains hydraulic pressure levels to ensure that every blow delivers the maximum power, yielding optimum productivity in all applications.
VIDAT tie rods
Vibration Dampened Tie Rods, spherical tie rod nuts and damper bushings ensures piston moves freely for longer, more productive working life.
Idle blow protector (Optional)
Idle Blow Protection ensures the hammer cannot be operated until pressure is placed on tool. This eliminates tie rod stress, reduces oil overheating and protects against premature failures.
Heavy duty set (Optional)
Additional wear resistant plating and stone claws, increase the wear life of the housing and aid with repositioning in boulder breaking applications.
Trenching is a form of primary breaking in which a narrow trench is excavated especially for laying pipes, cables or for installing drainage
Hydraulic excavators have largely replaced cranes with wrecking balls, enabling demolition to be carried out in a much more controlled and efficient manner.
Low clearance hammer tunneling
Especially in the underground mining industry the tunneling operations do not always allow for enough clearance, this restricts the types of carriers that can work in these environments.
- Asphalt Cutting
When blasted rock is too big for the feeder or crusher, secondary breaking is needed to get the boulders down to size. The type of rock dictates the effectiveness of the process, with brittle rock giving the best performance.
Blockages and build-ups
Stationary pedestal booms equipped with breakers are used extensively on crushers for breaking oversized boulders and clearing material for smooth and continuos feed flow.
