CM 2113 2026 CONTRACTS,
PROCUREMENT AND LEGAL PRINCIPLES
LEARNING OUTLINE
◉Fill factor Answer: adjusts heaped capacity in lcy based on the
type of material being handled
◉Excavators job efficiency Answer: Management conditions:
- Skill, training, and motivation of workers
- Planning, job layout, supervision, and coordination of work
Job conditions:
- Topography and work dimensions
- Surface and weather conditions
◉cranes Answer: Mobile cranes and tower cranes are the primary
machine used for the vertical movement of construction materials
, ◉crawler cranes Answer: mounted on a pair of parallel crawler
tracks, which provide the crane with good travel capability around
the job site
◉telescoping boom truck mounted cranes Answer: -Travel on
highways, can change boom length, have outriggers for stability.
-Outriggers on large steel mats to reduce ground pressure and
prevent damage to pavement
-Crane positioned on hollow-core precast concrete panel slab
◉Lattice-boom truck mounted cranes Answer: The lattice-boom
structure is lightweight. This reduction in boom weight means
additional lift capacity, as the machine predominately handles hoist
load and less weight of boom
◉rough-terrain cranes Answer: These units are equipped with
unusually large wheels and closely spaced axles to improve
maneuverability at the job site. They earn the right to their name by
their high ground clearance, as well as the ability to move on steep
slopes
◉All-terrain cranes Answer: They have an undercarriage capable of
long-distance highway travel. Yet the carrier has all-axle drive and
all-wheel steering, crab steering, large tires, and high ground
clearance.
