What it is for
Derrick Cranes
A stiff-leg derrick is erected on the roof or on a structure and stays there for the duration of the work. Nothing occupies the street, no daily setup and teardown, no road occupancy permits for a mobile crane every morning, and no waiting for a machine to come back next week.
This is the equipment of choice for long-running rooftop work: mechanical replacements, restoration, envelope and window programs, and any building where a mobile crane cannot reach the roof from grade or cannot be set up at all.
Best suited to
- Rooftop mechanical replacement
- Building restoration programs
- Sites with no street access
- Multi-month rooftop work
Working envelope
Diagram is indicative. Actual capacity at any radius comes off the load chart for the specific machine and configuration, confirmed in the lift plan.
