Steering problem in dumpers pose significant risks in mining operations. These failures, often arising from mechanical or hydraulic issues, can lead to loss of control, accidents, and injuries to operators and bystanders. Mechanical failures, such as worn steering components or linkage failures, may result from prolonged use, inadequate maintenance, or manufacturing defects. Hydraulic failures, including leaks or pump malfunctions, can impair steering responsiveness and maneuverability. Addressing steering failures requires prompt identification, thorough inspection, and timely repairs to ensure the safe operation of dumpers in mining environments. Proactive maintenance, operator training, and adherence to safety protocols are essential for mitigating the risks associated with steering failures and maintaining a safe working environment in mining operations. Root Cause Analysis (RCA) on steering problems of mining dumpers includes data collection, investigation, fishbone diagram, root causes identification, and corrective actions and preventive measures.

Steering Problem

  Machine

• Cracks of radiator block
• Steering wheels/ seat in constant vibration
• Steering pump damaged
• Steering gear  box is loose in the chassis frame
• Uneven tyre pressure

  Man

• Improper maintenance
• Excessive backlashing of steering wheels

  Miscellaneous

• Sludge formation
• Rust/ scale formation
• Bumpy roads
• Uneven force on/ off-centre steering wheel
• Improper operating knowledge

  Materials

• Steering drift
• Low power steering fluid
• Loose/ worn out steering belt
• High thermal expansion of connection rod

By conducting RCA on steering problems of mining dumpers, organizations can systematically identify and address underlying issues to enhance the reliability, safety, and performance of dumpers in mining operations.

Who should use the Steering Problem template?

• Maintenance, engineering, operations, quality assurance teams, and safety officers may find this RCA fishbone template beneficial.

Why use this template?

• Using an RCA Fishbone diagram template for steering problems in dumpers provides a structured approach to identifying root causes and developing solutions. These techniques facilitate systematic analysis and collaborative investigation.
• The visual representation of the Fishbone diagram enables teams to brainstorm and prioritize potential root causes efficiently, leading to targeted investigations and timely implementation of corrective actions.
