ACCELERATOR PEDAL

560 452 01 ACCELERATOR PEDAL Located within the main body of the hydraulic drifter, this component acts as a high-speed energy reservoir. It accumulates pressurized hydraulic fluid and then discharges it in a powerful, instantaneous burst. This rapid release of energy is what accelerates the drifter's piston to create the strong percussion needed for breaking rock. Its function is essential for achieving the designed impact frequency and energy per blow.

A properly functioning ACCELERATOR PEDAL is directly linked to the rig's productivity. If the internal nitrogen pre-charge is incorrect or has leaked, the drifter loses a significant amount of its impact power, resulting in a slow penetration rate. For example, a drifter that sounds 'soft' and struggles to advance is often a symptom of a faulty ACCELERATOR PEDAL. This inefficiency puts extra strain on the entire hydraulic system, potentially leading to overheating.

A sudden drop in drilling performance is the most common sign that the ACCELERATOR PEDAL needs attention. Before replacing the unit, the nitrogen pre-charge level should be checked with the correct service tools as per the manual. Always ensure the hydraulic system is fully depressurized and the gas charge is safely released before attempting removal.
