New PRO hammers from Rammer

Published 22/4, 2016 at 13:30

Rammer has introduced two new PRO hammers the Rammer 2577 PRO and Rammer 5011 PRO. They are suitable for carriers in the 21t to 32t and 43t to 80t weight range respectively. They have been designed to work horizontally and undertake tunnelling duties in hard rock, being purpose built to withstand high levels of dust.

The 1.94t Rammer 2577 PRO and the 5.3t Rammer 5011 PRO are based on the proven Rammer 2577 and 5011 hammers. Both new models possess features such as an Idle blow protector that works regardless of working mode to provide greater levels of protection. Additionally they are equipped with long-life, high-tension VIDAT tie rods for improved reliability, extended service periods and lower operating costs.

These standard Rammer features are backed by a range of enhancements that help the PRO range to withstand extreme working conditions. Customers will be able to benefit from a sealed housing structure that prevents the ingress of dust and dirt, thereby extending the working life of both the hammer and the tool. A top cover plate has sealed through apertures for stump hydraulic hoses, and features sealed hose connections for grease, air and water.

The PRO hammers have a housing design and wear plates that make them perfect for horizontal working duties, including applications such as tunnelling. To match the demands of the extreme applications, the Rammer PRO range models are also offered with special tools for horizontal primary breaking, which have been designed to work with a broad range of auxiliary systems.

For customers working in tunnelling applications, Rammer has a package of auxiliary systems and solutions such as the air grease water. These have been designed to protect the hammer from the demands of this extreme application; delivering lower owning and operating costs.

The air grease water unit comprises special features designed to aid tunnelling activities. These consist of the Ramair air flush system that prevents potentially harmful dust ingress; the Ramlube I automatic lubrication system to ensure consistent and thorough greasing; and the water jet dust suppression package to minimize the creation of dust during breaking.

Hydraulically actuated and requiring no additional power supply, the air grease water unit is easy and safe to install and maintain. It helps ensure that all Rammer PRO hammers are protected and productive throughout their working life. All these key features are backed by long life, wear resistant Rammer parts available from the Rammer global dealer network.
