PRACTICE Boring,
PRACTICE Boring, hammering and drilling systems are exposed to severe stresses. Hammer drills can be rather expensive. Hammer drill oil has the important job of protecting this valuable piece of equipment against wear and keeping it operating smoothly in the most challenging conditions. It’s hard to even imagine building a tunnel without hammer drills. Properly maintained and operated, hammer drills can serve us well. ROTAC BIO FOR THE ROUGH WORK Picture: Sandvik/Tamrock ALWAYS LUBRICATE! Proper lubrication is the most important and affordable part of maintaining pneumatic and hydraulic mining equipment. Since the oil mist in the compressed air that operates the device is ultimately released into the environment, a rapidly biodegradable hammer drill oil is recommended. Hammer drill oil consumption can vary widely, depending on the amount of compressed air required, operating pressure setting and manufacturer’s specifications. MOTOREX ROTAC BIO High-performance, rapidly biodegradable ROTAC BIO hammer drill oil with ISO VG 100 viscosity is generally suitable for use in compressed air tools. The fully synthetic fluid mixes well with compressed air, absorbs moisture in a controlled fashion and offers ideal protection against corrosion. Special additives prevent the compressed air’s moisture content from crystallizing (freezing). The following benefits make MOTOREX ROTAC BIO a compelling choice: HAMMER DRILLS The first hammer drills were used in tunnel construction as early as 1860, and later also in mining. At one time they were purely pneumatic. Today the impact and drilling mechanism is hydraulic, but moving parts are still lubricated and cooled by hammer drill oil carried by compressed air. At the end of the process the air-oil mixture is expelled onto the movable hammer drill’s slide tracks, where it lubricates them as well. Picture: Sandvik 24.5 kW Sandvik HFX5 hammer drill clean compressed air mixed with hammer drill oil used compressed air mixed with hammer drill oil released to lubricate slide track • Outstanding corrosion and wear protection • Wide operating temperature range • Ideal pressure absorption capacity • Designed for high percussive performance • Binds and removes moisture • Optimum adhesion • Lubricates slide tracks QUALITY PAYS OFF With improper or inadequate lubrication – or worse still, none at all – hammer drills have been shown to generate extremely high temperatures in less than one minute of operation. Paying the necessary attention to the hammer drill’s lubrication system and using the right hammer drill oil can prevent the risk of costly work stoppages.
