Overview
Mobile cranes include truck-mounted hydraulic cranes, all-terrain cranes, rough-terrain cranes and smaller carry-deck or boom truck units. They drive to the site, set up on outriggers and perform lifts, making them common for construction, equipment setting and installations.
Crane size is chosen based on load weight, rigging weight, radius, height and site conditions. A crane's capacity drops as radius increases, so a crane rated for a heavy load at close range may handle much less at the distance your job requires. Load charts and lift planning determine the right machine.
Site requirements include stable ground for outriggers, access for the crane and support vehicles, clearance from power lines and space for counterweights.
What to expect, step by step
- Discussing the load, radius and site.
- Selecting crane type and size.
- Planning setup location and access.
- Coordinating permits for street setups.
- Performing the lift with qualified operators and riggers.
- Demobilization.
Things worth considering
- Capacity depends on radius.
- Ground bearing pressure matters.
- Power line clearance is critical.
- Permits may be needed for street setups.
- Weather and wind affect lifts.
- Minimum charges and travel time apply.
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.

How to prepare your inquiry
- Share your preferred dates, working hours and how long you expect to need the equipment or service.
- Include photos of the site and the setup area if you can.
- List the heaviest and largest items or loads, with approximate weights and dimensions, or share the equipment spec sheet.
- Note any site rules, such as general contractor requirements, safety orientation, insurance certificates or restricted hours.
- 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.
- Mention whether you need an operator, rigging, delivery, permits or traffic control, or plan to handle those yourself.
Red flags to watch for
- Quotes that change significantly on the day without a clear reason.
- No questions about loads, ground conditions or site access before quoting.
- Vague answers about equipment inspection and maintenance records.
- Pressure to proceed without a lift plan or site visit on a complex job.
- Unwillingness to provide insurance certificates or operator qualifications when asked.
- No written quote that lists equipment, minimum charges, travel, overtime and cancellation terms.
- Dismissing wind, weather or ground concerns rather than explaining how they will be managed.
