Operated and Maintained Crane Service Guide: Denver

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.

The usual process

Crane and operator provided.
Maintenance handled by the crane company.
Optional riggers and signal persons.
Lift planning support.
Setup and teardown.

Things worth considering

Responsibilities should be clear in the contract.
Additional personnel may be extra.
Overtime rates may apply.
Insurance requirements vary.
Operator qualifications should be verified.

Local notes for Denver

Wind along the Front Range, especially near the foothills, can affect crane operations, and lifts are postponed when conditions exceed limits. Altitude does not change crane load charts, but weather windows and ground conditions after snowmelt matter.

We take inquiries from Denver, Aurora, Lakewood, Littleton, Arvada, Westminster.

What to have ready

Describe the job site: address or nearest cross streets, access route, ground conditions and any overhead lines, trees or structures.
Note the lift height, reach or pour distance needed, measured from where the equipment would set up.
Tell us who the on-site contact will be on the day of the work.
Note any site rules, such as general contractor requirements, safety orientation, insurance certificates or restricted hours.
