Marchington Stone operates Shire Hill Quarry, a live quarrying environment using heavy plant and machinery for daily operations. As part of a scheduled maintenance programme, the site required a specialist deep clean of key equipment to allow safe and effective mechanical work to take place.
The machinery selected for cleaning included:
• CAT 980M Loader (29,000kg)
• Doosan DX530 Heavy-Duty Crawler Excavator (53,000kg)
Both machines had accumulated significant levels of mud, clay, oil and grease through continuous quarry operations.
Project
Shire Hill Quarry – Marchington Stone
Client Type
Commercial Quarry / Heavy Industry
Services Delivered
• Heavy machinery deep cleaning
• Oil and grease removal
• Mud and clay build-up removal
• High-pressure superheated water cleaning
• Degreasing (TFR)
• Industrial site cleaning
• RAMS-led service delivery
The Challenge
The machinery required a full deep clean prior to maintenance work being carried out, to:
• Remove heavy mud and clay build-up
• Strip oil and grease from critical components
• Improve safe access for engineers
• Support effective inspection and repair
All works needed to be carried out within a live quarrying environment, presenting additional safety and operational constraints.
Rokjet was required to liaise closely with the on-site safety team, submit detailed RAMS (Risk Assessments and Method Statements) and work within strict site safety controls.
Our Solution
Rokjet was appointed to deliver a specialist heavy plant cleaning service at Shire Hill Quarry.
We deployed high-pressure superheated water combined with an industrial degreaser (TFR) to break down and remove oil, grease, clay and heavy surface contamination from the machinery.
The CAT 980M Loader (29,000kg) and Doosan DX530 Heavy-Duty Crawler Excavator (53,000kg) were systematically cleaned, including:
• Undercarriages and track assemblies
• Engine bays and access panels
• Hydraulic components and housings
• Working arms, buckets and attachments
• Operator access steps and handrails
Our team worked in close coordination with the site safety team to agree a safe working plan, including controlled work zones, plant isolation procedures and site-specific safety protocols.
Full RAMS documentation was submitted and approved prior to works commencing.
Why This Matters for Industrial Operators
• Enables safe and effective maintenance work
• Improves inspection visibility of mechanical components
• Reduces contamination and fire risks
• Supports health & safety compliance
• Demonstrates proactive asset management
• RAMS-led, safety-first service delivery
