· • The productivity of the excavator determines the number of dump trucks that an excavator can accommodate within the estimated production time. 3.2. Estimated volumetric capacity of the backhoe bucket Bucket capacity is a measure of the maximum volume of the material that can be accommodated inside the bucket of the backhoe excavator.
· Difficulty: Moderate Instructions Understand the formula for calculating excavator productivity. The formula is 1 as follows: Q = (60*q*z*n*kf) / kl, where Q is the productivity of the excavator, q is the capacity of each rotor bucket in cubic feet, z is the number of buckets on the wheel and n is the speed of rotation of the rotor, measured in ...
The bucket capacity required for a job depends on the hourly production requirement, the density of the material, how full the bucket can be loaded for a particular type of material, called the "fill factor," and the cycle time. The hourly production requirement is set by project management.
· The aim of this work is to evaluate if the number of cycles estimated until the failure of the bucket wheel can be reached considering a preexisting crack in the wheel structure, being calculated the critical length of this crack so that the stress intensity factor K has the same magnitude of fracture toughness K IC.In addition, fatigue life will be evaluated based on S-N curves for welded joints.
· Chapter 2 Page 1 Chapter 2 Productivity of Construction Equipments: Earthwork Equipments Definition: - Productivity in construction is defined as a unit output per hour.An accurate prediction of the productivity of construction equipment is critical for construction management.

· n Compact bucket wheel excavator n Cross-pit conveyor bridge n Compact spreader n Effective output up to 7,000 m³/h A large variety of possible combinations of these ma-chines with individually matched spreaders and belt conveyor systems, as well as cross-pit spreaders, ensures efficient, cost-saving operations.
· The bucket wheel and gearbox can only be inadequately protected in these overload situations through the basic protection system. Bucket wheel. The bucket wheel was also replaced along with the drive. The new single bar configuration facilitates changing of wear elements and improves the accessibility of the design.
7. V. I. Seroshtan, Investigation of the Mutual Relations between the Parameters of Working Equipment of Bucket-Wheel Excavators and the Face, on the Basis of the Example of Working Deposits of Non-Ore Building Materials [in Russian], Author's Abstract of Thesis, Kiev (1970). 8.
Then figure the square footage. (Above, we noted that using a 6" grid gives you .25 square feet per square.) This is your cross-sectional area. Finally, to calculate the volume, multiply the cross-sectional area by the length of the bucket, in feet. And there you have it – estimated bucket capacity for your 2.5-yard wheel loader.
· (track-type, wheel-type, and compact), skid-steer loaders, backhoe loaders and integrated tool-carri-ers. Work tools or any tool used in hazardous appli-cations like demolition and logging, can create a need for special operator guarding. When flying debris from impact, cutting, shearing or sweeping attach-
· 6. Calculate the volume by multiplying the cross sectional area in square feet by the length in feet. Using the 148" width as an example: 148 inches in feet is: 148 / 12 = 12.33 feet In North America, most bucket capacities are expressed in cubic yards so it is important to know that one cubic yard contains: 1 yard = 3 feet. so 3 ft. x 3 ft. x ...
· •Rate analysis of excavation in earthwork use of IS Code 1200 part 1, Part 27, IS 4988, IS 12138 (Part IV) and CPWD for calculation is this measurement of the quantity of excavation to be carried out, the cost of labour, machinery, and other equipment like hard soil for breaker, etc.
