Backhoe dredgers - A backhoe dredger is a mechanical

"Backhoe dredgers" are water-based excavators that evolved from the land-based backhoe. The water-based backhoe dredger is a stationary, hydraulic crane mounted on a dedicated dredging pontoon that often has a rotating table. The word "backhoe" does not refer to its location on the back of a vehicle or pontoon.

Productivity in Construction

1986 and 1990, the productivity of construction labour in Japan increased by 6.6% a year, while Canadian construction productivity rose by only 1.6% . In response to this dilemma, the Con­ struction Division of the Canadian Society for Civil Engineering (CSCE) developed and im­ plemented a program with a view to improving productivity.

Productivity Considerations for Shovels and Excavators

"Backhoe configurations are slightly different and the cycle times can be quite fast compared to front-shovel configurations," Sammut said. "If the backhoe is set up correctly with the truck on the lower level with the bucket raking up the face and a low swing angle [20º to 30º], the cycles time could be as little as 20 to 23 seconds.

Influence of Crushed Rock Properties on the Productivity

Feb 12, 2021 · To obtain effective excavator productivity, technical productivity must be corrected by mainly modifying the estimation factors: operator competence, operator utilization, and excavator efficiency. Excavator efficiency is called "random conditions" [ 13 ] and "natural variability" [ 6 ] and depends on specific conditions at the work site.
