Truck-Mounted Hydraulic Excavators
Historical Construction Equipment Association (HCEA)
Rubber-tired carriers of cable-operated excavators filled a niche into the 1960s.
This image from a Hein-Werner advertisement illustrates one of the problems faced by a truck-mounted backhoe: When a backhoe has to be moved to continue the trench, the operator has to change cabs twice rather than simply propelling from the excavator cab.

The Double-Boom Excavator
Historical Construction Equipment Association (HCEA)
The annals of construction equipment design history contain quite a few oddballs, experiments, eccentricities and other contraptions that seemed like good ideas on the drawing board but just never took hold.
The Double Boom Excavator is seen here equipped with two 2.5 cu. yd buckets at work near Mounds, LA.
