HEMM Job Services Details

➢ Site Visit and Inspection: Conduct an initial visit to the site to inspect the machinery and understand the operational environment.

➢ Identification of Critical Machinery: Identify and prioritize the machinery that requires vibration analysis based on usage, age, and criticality.

➢ Instrument Setup: Install appropriate vibration sensors on key components of the HEMM such as engines, gearboxes, transmissions, and hydraulic systems.

➢ Routine Data Collection: Schedule and perform routine vibration data collection during different operational conditions (e.g., idle, loaded, and peak performance).

➢ Data Analysis: Analyse the collected vibration data using specialized software to identify abnormal vibration patterns, resonance frequencies, and potential issues.

➢ Diagnosis of Issues: Diagnose specific issues such as misalignment, unbalance, bearing wear, gear faults, or other mechanical problems.

➢ Recommendations: Provide actionable recommendations for corrective actions such as rebalancing, realignment, component replacements, or design modifications.

➢ Site Survey and Machinery Identification: Conduct an initial site survey to identify the specific HEMM that will undergo noise testing. This includes cataloging the types of machinery, their operational roles, and the environments in which they operate.

➢ Regulatory Compliance Review: Review relevant noise regulations and standards (such as OSHA, ISO, and local environmental laws) to ensure that the testing process meets all legal and industry requirements.

➢ Baseline Noise Measurement: Perform baseline noise measurements with the machinery in an idle state to establish reference noise levels.

➢ Operational Noise Testing: Conduct noise measurements during typical operating conditions, including during startup, normal operation, and under full load. Capture noise levels at various operating speeds and under different types of loads (e.g., digging, lifting, moving).

➢ Environmental Noise Measurement: Measure the ambient noise levels around the operational area to differentiate between machine noise and background noise.

➢ Frequency Analysis: Perform a frequency spectrum analysis to identify specific frequencies contributing to noise levels, which can help in pinpointing sources of excessive noise, such as specific components or mechanical faults.

➢ Identification of Noise Sources: Analyze the data to identify specific components or operations that are contributing to excessive noise levels.

➢ Risk Assessment: Assess the potential health and safety risks associated with the measured noise levels, particularly for machine operators and nearby personnel.
