⩥ 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 and 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 and job size
⩥ Articulated trucks consist of two individual frames joined by pin, and
can be easily operated over soft ground. Answer: True
, ⩥ A contractor wants to investigate the production and cost differences
of using a 4S blade on a crawler-type dozer (D4H-4S). The material is
dry clay and is to be moved a distance of 150 ft from the beginning of
the cut. The dozing is uphill on a 20% grade. The operator will have
average skill. The site conditions will be dark for visibility. The material
weighs 108 pcf in the bank state. Job efficiency is assumed to be
equivalent to a 50-min hour. What is the operator correction factor?
Answer: .75
