Job conditions:
- Topography and work dimensions
- Surface and weather conditions
cranes
Mobile cranes and tower cranes are the primary machine used for the vertical
movement of construction materials
crawler cranes
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
-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
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
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
crawler cranes for heavy-lifting
additional counterweight mounted on a wheeled platform to increase lifting capacity.
Ring system, "ringer," a heavy counterweight system supported on a large circular
turntable ring
, All-terrain cranes
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.
Pros and cons of different types of cranes
Rough terrain crane "pickers"
-Pros= off road applications, set up quickly, very maneuverability.
-Cons= limitation of capacity and cost of freight
*All terrain crane
-pros= travel on highway and rough terrains
-cons= limitation of capacity, set up time, maneuverability and foot print.
*Crawler
-Pros= don't require outriggers, very high lifting capacity, any site even soft soils,
travel with load
-Cons= expensive, set up time, large foot print, lot of matting, larger number of
fall off loads
top slewing cranes
cranes can increase their height
Tower cranes
The flexibility of its freely suspended hook moving in three planes provides a
tremendous advantage in terms of load pick-up and positioning.
Advantage of having both the operator and jib above the construction site.
