Rammer has unveiled a new model that further completes its large range of hydraulic hammers. Designed to meet the demands of professional users, the new Rammer 5011 is designed using the same operating principle as first seen on the smaller 3288 and 4099 models. This operating principle that has raised the standards in power to weight ratios, allows these hammers to be purpose-matched to specific applications for increased productivity and usability. Suitable for carriers in the 43 to 80 ton (39 to 72.5 t) operating weight category, the 5011 model weighs in at 10,470 lb. (4,750 kg) and slots neatly into the Rammer large range line-up between the 4099 and 7013 models to provide customers with a complete range of hammers.
The new Rammer 5011 benefits from a number of key features including:
• Flexible operating principle — Stroke length and idle blow protection can be easily adjusted to allow the hammer to be better matched to the applications at hand.
• Improved hydraulic efficiency — Delivers massive impact energy and high blow frequency for exceptional power-to-weight ratio.
• Lower operating costs — Rammer’s VIDAT (vibration dampening tie rods) system provides improved reliability and minimizes downtime while a modern sealing system and enhanced lubrication help to reduce operating costs.
Flexible Operating Principle
Rammer’s new 5011 utilizes the same operating principle that allows it to be purpose-matched to individual applications and materials by using two simple working mode selectors located on the hammer. The long stroke setting uses a lower blow frequency for optimum breaking in hard materials, such as granite and reinforced concrete foundations, while the short stroke setting delivers higher blow frequency, which is ideal for softer materials, such as limestone. The idle blow protector on/off selector allows the operator to easily adjust the working mode to provide protection against idle strokes.
Like the other models in Rammer’s large range of hydraulic hammers, the new 5011 is designed for a long, trouble-free life. Simplified and more robust hydraulics feature less valves and greater back-pressure tolerance, making them the ideal match for a wide range of carriers and hydraulic flow rates. The new model utilizes long-life, high-tension VIDAT tie rods for improved reliability and lower operating costs. The tool-retaining pins are locked by simple, reliable rubber rings, while the surface of the lower tool bushing has been specifically designed to provide longer tool life, according to the manufacturer.
To further extend the working life of the Rammer 5011 it is offered with three greasing options: a centralized manual option; carrier-mounted Ramlube I automatic greasing; or Ramlube II, which utilizes a cartridge mounted on the hammer to automatically deliver optimum levels of lubrication for greater wear protection and a longer service life. The new model also comes equipped with Rammer’s Ramdata II service indicator that allows operators and service personnel to monitor and log vital service and maintenance information.
