◉An advantage of a crawler dozer as compared with a wheel-type
dozer is higher speed. Answer: False
◉Which of the following work tasks can be performed by a dozer?
Answer: -Spreading
-Striping
-Backfilling
◉The ________________ is very effective for side-casting material,
particularly for backfilling or making sidehill cuts. Answer: Angle
Blade
◉______________ is a technique whereby the blade end spillage from
the first pass or the sidewalls from previous cuts are used to hold
the material in front of the dozer blade on subsequent passes.
Answer: Slot dozing
◉Which of the following factors need to be considered when
selecting a proper scraper for your project? Answer: -Scraper
configuration
,-Volume of material
-Job size
◉Articulated trucks consist of two individual frames joined by pin,
and can be easily operated over soft ground. Answer: True
◉Buckets of loaders are rated in both heaped and struck capacities.
_________________ is based on the SAE standard of a 2:1 material repose
angle. Answer: Heaped capacity
◉Which of the following is a job condition that could affect the
operator's job efficiency? Answer: Surface and weather conditions
◉Fill factor is the ratio of the actual loose volume of material in the
bucket compared to the bucket's rated-heaped capacity. It varies
based on the type of material being handled and the type of
excavator. Answer: True
◉Which of the following is not a disadvantage of a crawler crane?
Answer: Limited capacity
◉Straight blades Answer: Shh hi pet and medium distance passes,
such as backfilling, grading, and spreading full material
, ◉Universal blades Answer: Working stockpiles and drifting loose or
no cohesive materials
◉Semi-U blade Answer: Combination of the S and U blade designs
◉Cushion blades Answer: Mounted on large dozers that are used
primarily for push-loading scrapers. limited utility in pushing
material and should not be used for production dozing. Cannot be
tilted, pitched or angled.
◉Side-to-side Answer: Blade-to-blade dozing. Two machines
maneuver so that their blades are next to each other during the
pushing phase of the production cycle.
◉What factors affect dozer real production rates? Answer: 1. Blade
type
2. Type and condition of material
3. Cycle time
◉Scrapers Answer: Excavating, loading, hauling and dumping
material over medium to long haul distances
◉Scrapers production cycle Answer: 1. loading
2. haul travel
