Mining wheel scraper mucking loaders are vital equipment in mining operations, facilitating the efficient removal of debris and muck from underground tunnels and shafts. However, several factors can contribute to a decline in the efficiency of these machines, impacting productivity and performance.

Before delving into operational issues, it’s essential to ensure proper maintenance procedures are followed. Hydraulic oil levels must be maintained above three-fourths of the tank capacity, with regular oil changes every 100 hours of operation to prevent hydraulic system malfunctions.

The primary cause of decreased working speed in mining wheel scraper mucking loaders is wear and tear on various components, resulting in reduced power output and hydraulic system leakage. Over time, internal components of the hydraulic pump, such as the cylinder block, pistons, distributor plate, and others, experience excessive wear, leading to internal leakage and inadequate flow rates. This necessitates comprehensive machine overhauls to repair or replace worn components.

However, sudden slowdowns in loaders may indicate electrical or hydraulic issues that require immediate attention. Checking circuit fuses for breaks or shorts and ensuring normal pilot pressure are initial steps. Subsequent inspections should focus on servo control valves, servo pistons, and distributor convergence for any malfunctions. If problems persist, dismantling the hydraulic pump for thorough measurements and diagnostics is necessary to pinpoint the root cause.

Additionally, regular inspections every six months are crucial to identify wear and tear on components like support wheels, guide wheels, sprockets, and track segments. Timely replacement of severely worn parts ensures uninterrupted operation and prevents further efficiency losses.

In conclusion, proactive maintenance, timely component replacements, and thorough diagnostics are essential to maximize the efficiency and longevity of mining wheel scraper mucking loaders in demanding mining environments.
