In 1838, the industrialist and businessman William Armstrong designed a water-powered hydraulic crane. Alternatively, the medieval treadwheel may represent a deliberate reinvention of its Roman counterpart drawn from Vitruvius' De architectura which was available in many monastic libraries. From Business: Operational for more than 80 years, John Crane designs and manufactures a range of engineered and mechanical seals. Instead of setting up a large crane to construct a wind turbine tower, a smaller climbing crane can help build the tower, climb with it to the top, lift the generator housing to its top, add the rotor blades, then climb down.

Exchanging mobility for the ability to carry greater loads and reach greater heights due to increased stability, these types of cranes are characterised by the fact that their main structure does not move during the period of use. During development of cranes, load level (lifting load) can be significantly increased by taking into account the IIW recommendations, leading in most cases to an increase of the permissible lifting load and thus to an efficiency increase.[67]. They are opportunistic feeders that change their diets according to the season and their own nutrient requirements. Tower cranes are used extensively in construction and other industry to hoist and move materials. United Rentals offers portable gantry cranes that can lift up to 725 lbs.
