Hopto was the brand name used by Warner & Swasey of the USA on a range of excavators built in the 1950s and 60s. The JCB 7 360 degree excavator was based on a Hopto design
The Hopto name originated with the Badger Construction Equipment Company, a subsidiary of the Warner & Swasey company. The first Hopto machine was a tractor mounted hydraulic backhoe - Hydraulically Operated Power Take-Off.
The Gradall brand was also owned by Warner & Swasey who bought the rights to the design in 1946 from the Gadall's designer Ray Ferwerda of Cleveland Ohio.
