Key Challenges & Highlights
Rapid Emergency Response
Works were instructed on a Friday and required overnight mobilisation of a full equipment train – specialist grab, tractor trailers and recycler – to be set up and operational by Saturday morning.
Extremely Confined Working Conditions
The tight HGV tipping access above the silo and the narrow internal chambers severely restricted plant manoeuvring. The specialist grab was essential to reach material within the strengthening supports and screw shaft divisions.
Confined Space Excavation
Working deep within the cake silos required the specialist grab to clear blocked material without damaging the silo structure or screw shaft mechanisms.
