Stiffleg and shearleg construction derricks

Construction derricks

Timberland, home of the original Adjustable Stiffleg Derrick, has supplied derricks to support construction of many of the world’s tall buildings.

Adjustable 17-ton and 35-ton Stiffleg Derricks from Timberland allow greater flexibility and lower costs at the time of installation.

Timberland Shearleg Derricks range in size from 50-ton to 350-ton lift capacity.

Timberland modular material hoists are recommended for use with any Timberland derricks.
