Describe the service boundary
Separate extraction from material handling, plant repair and delivery. Identify whether your company controls the process or works under the owner’s direction. A service agreement may assign responsibility for both the equipment you operate and finished material, so the insured operations should be compared with the entire contract.
Follow mobile plant values
Track crushers, screens, conveyors, generators and hired support equipment. Review valuation, transit, assembly and leased-property provisions rather than assuming a single machinery schedule resolves every exposure. Business income at your own premises may not respond to a customer’s interruption caused by a mobile plant incident.
Account for neighboring interests
Dust, runoff, vibration and vehicle interactions can affect third parties as well as the mine operator. Discuss these circumstances with the insurer and separate pollution questions from ordinary liability. Provide site layouts and a clear explanation of public-road use, subcontractors and responsibility for access roads.
Illustrative review scenario
A mobile aggregate contractor moves a crushing spread to a new customer site and adds a rented generator for the project. The equipment list has not changed since renewal. Review the new location, generator value, rental agreement and assembly responsibilities before operations start. The customer’s insurance requirements may also differ from those at the previous site, even though the contractor uses the same principal machinery. Who is responsible for damage when a mobile crusher is being assembled at a new location? Identify the equipment owner, installation contractor and applicable insurance provisions before the mobilization begins.
