Overview
Operated and maintained, often abbreviated O&M, means the crane comes with a qualified operator and the crane company is responsible for maintenance. This is common for mobile crane rentals.
Bare rental, where the customer provides the operator, is less common and carries more responsibility for the customer.
O&M service may include additional personnel such as oilers, riggers or signal persons depending on the crane and job.
How it typically works
- Crane and operator provided.
- Maintenance handled by the crane company.
- Optional riggers and signal persons.
- Lift planning support.
- Setup and teardown.
Before you decide
- Operator qualifications should be verified.
- Overtime rates may apply.
- Responsibilities should be clear in the contract.
- Additional personnel may be extra.
- Insurance requirements vary.
Local notes for Orange County
In California's dense urban areas, street setups frequently need city permits and traffic control, and many lifts are scheduled early in the day to minimize disruption. Projects near the coast may contend with marine-layer fog.
